Battery Maintenance
• When the customer receives the battery, they should check the basic function first, and make sure no damage occurred during transport. Please test the battery voltage, charging function, discharge function, and display function; if there are any anomalies, please stop installation and notify us immediately. After installing the battery according to the installation manual, fully charge the battery before using it for the first time. Upon being fully charged and discharged between three and five times, the battery will reach its maximum capacity.
• To prolong their lifecycle, charge batteries when their capacity is low. If batteries are not charged during this time and they are left in a deficient state for a prolonged period, this will adversely affect the battery life. If those batteries will not be used for a long time, keep them at half-capacity and float-charge the battery every two months, for one hour each time.
• The battery should be installed in a dry, clean, and wellventilated area, while avoiding ignition sources and proximity to flammable materials. Be sure to disconnect the load (i.e., turn off the electrical equipment) during charging.
• The working temperature of the battery is 41–104°F. (Optimal working temperature is 59–95°F.) Outside this temperature range, the performance of the battery may change. Under such circumstances, it is normal for the capacity or the equipment operating time to change.
• Avoid cleaning the battery case with organic solvents. 
• If an accident occurs, do not use carbon dioxide to extinguish the fire; instead, use carbon tetrachloride or sand to extinguish it.
• The battery is a consumable item and its lifecycle is limited. Please replace the battery when the battery capacity is lower than 50% of the rated capacity.

HARGING GUIDELINES

If LiFePO4 batteries are not fully discharged, they do not need to be charged after each use. LiFePO4 batteries do not get damaged when left in a partial state of charge (PSOC). You can charge your LiFePO4 batteries after each use or when they have been discharged up to 80% DOD (20% SOC). If the Battery Management System  BMS) disconnects the battery due to low voltage (voltage will be <10V), remove the load and charge immediately using a LiFePO4 battery charger.

CHARGING TEMPERATURE

LiFePO4 batteries can be safely charged between 0°C to 45°C (32°F to 113°F). LiFePO4 batteries do not require temperature compensation for voltage when charging at hot or cold temperatures. All Canbat LiFePO4 batteries come with an internal BMS that protects the battery from low and high temperatures. If the BMS disconnects due to low temperature, the battery must warm up for the BMS to reconnect and accept the charging current. If the BMS disconnects because of high temperature, the battery will need to cool down before the BMS will accept charging the battery. Please refer to your specific battery’s datasheet for the BMS low temperature and high-temperature cut-off and reconnect values.

The charging and discharging temperature for lithium batteries from our LT series is -20°C to 60°C. Canbat Low Temperature (LT) Lithium Batteries are cold-weather rated, designed for Canada’s cold climates. These batteries have a built-in heating system featuring proprietary technology that draws power from the charger. No additional components are required. The entire process of heating and charging is completely seamless. The heating system automatically activates once charging below 0°C is attempted, and it automatically deactivates when it’s no longer needed. The heating system does not take power from the battery, but rather from the charger, ensuring the lithium battery is not discharging itself and keeping you powered. Simply plug the LT lithium battery into the LiFePO4 charger and the internal heating and monitoring systems take care of the rest.

HOW TO CHARGE LIFEPO4 BATTERIES WITH A LEAD-ACID CHARGER

Most lead-acid battery chargers can be used with LiFePO4 batteries as long as they are within the appropriate voltage guidelines. AGM and Gel algorithms typically fall within the LiFePO4 voltage requirements. The voltage for flooded battery charging algorithms is often higher than LiFePO4 charging requirements, which will result in the BMS disconnecting. If this happens, it is generally good practice to replace your charger for one with a LiFePO4 charge profile. Since the BMS protects the battery, using lead-acid chargers will typically not damage the battery.

Note that if the BMS disconnects due to low voltage, a lead-acid battery charger may not be able to reconnect the BMS, even if the charger has the acceptable charging parameters to charge LiFePO4. This is because when the BMS disconnects, the lithium battery will not have a voltage as it will read 0V on a voltmeter, while lead-acid chargers require the battery to read out a voltage to start charging. If the battery is reading 0V, the lead-acid battery charger will not be able to understand that a battery is connected and that it should start charging. This is also true for some low-quality lithium chargers. It is always recommended that you invest in a high-quality LiFePO4 charger to ensure high performance and longevity. Feel free to contact Canbat should you have any questions.

CHARGING LIFEPO4 IN PARALLEL

When connecting LiFePO4 batteries in parallel, please make sure each battery is within 0.1V of each other before putting them in service, This will minimize the chance of imbalance between batteries. If you’re charging 12V LiFePO4 batteries, the charging voltage should be between 14V – 14.2V. When charging 24V batteries in parallel, the charging voltage should be 28V – 28.4V. Charging 36V lithium batteries in parallel requires a voltage of 42V – 42.6V. Finally, charging 48V LiFePO4 batteries require voltage parameters of 56V – 56.8V. Below is a table with a summary showing the voltage requirements for each system voltage.

 

System VoltageCharging parameters
12V14V – 14.2V
24V28V – 28.4V
36V42V – 42.6V
48V56V – 56.8V

 

The voltage parameters apply to both charging profiles CC and CC-CV. If your charger’s voltage is lower than those listed in the table, it will not damage your battery, but it will be undercharged, and it will not provide the full rated capacity of the battery. If your charger’s voltages are higher than those listed in the tables above, the BMS may disconnect the battery and you may have to remove the load to reconnect. We recommend you replace the charger to avoid this inconvenience and to invest in a high-quality LiFePO4 battery charger.

CHARGING LIFEPO4 BATTERIES IN SERIES

When connecting batteries in series, please make sure each battery is within 50mV (0.05V) of each other before putting them in service. This will minimize the chance of an imbalance between batteries. If your batteries get out of balance, the voltage of any battery is >50mV (0.05V) from another battery in the set, you should charge each battery individually to rebalance. You can charge each battery individually periodically to avoid imbalance. When charging LiFePO4 batteries in series, it is best to use a multi-bank charger that charges each battery individually to ensure the cells remain balanced. You can also use a 24V battery LiFePO4 charger or a 48V battery LiFePO4 charger if you’d like to charge your system as a whole.

CHARGING LIFEPO4 WITH AN INVERTER/CHARGER AND/OR CHARGE CONTROLLER

Below are the key, typical charger inputs when using an inverter/charger or charge controller for charging LiFePO4 batteries. Many inverter/ chargers require additional parameters, please contact Canbat technical support for assistance. LiFePO4 batteries do not require equalizing. LiFePO4 batteries do not require temperature compensation for voltage when charging at hot or cold temperatures.

CHARGING LIFEPO4 WITH ALTERNATOR AND DC TO DC CHARGERS

Depending on the quality of the alternator, it may work fine to charge LiFePO4 batteries without modifications. However, low-quality alternators with poor voltage regulation can cause the BMS to disconnect LiFePO4 batteries. If the BMS disconnects the batteries the alternator may be damaged. To protect your LiFePO4 battery and alternator, please be sure to use a compatible high-quality alternator or install a voltage regulator. You can also use a DC to DC charger to safely and effectively charge your batteries including house banks. Installing a DC to DC charger is the recommended option when it comes to charging lithium with an alternator.

FUEL GAUGES FOR LITHIUM BATTERIES

If you are using a voltage-based fuel gauge that is designed for lead-acid batteries, it will not accurately measure the state of charge (SOC) of LiFePO4 batteries. Please replace your fuel gauge with one that measures current rather than voltage to accurately measure the state of charge of lithium iron phosphate batteries.

If you have any technical questions, please contact Canbat Technical Support at +1 778-358-3925.

FREQUENTLY ASKED QUESTIONS (FAQ)

 

CAN I CHARGE LITHIUM WITH SOLAR PANELS?

Yes, you can charge Canbat lithium batteries with solar panels. In fact, you can charge them with any type of charging equipment, as long as the charging voltage is within 14V to 14.6V for our 12V LiFePO4 batteries.

 

CAN I CHARGE LITHIUM WITH AN ALTERNATOR?

Yes, but it is recommended to invest in a DC to DC charger to protect your LiFePO4 battery and alternator.

 

CAN I CHARGE LITHIUM WITH A LEAD-ACID CHARGER?

Most lead-acid battery chargers can be used with LiFePO4 batteries as long as they are within the appropriate voltage guidelines. AGM and Gel algorithms typically fall within the LiFePO4 voltage requirements. The voltage for wet cell or flooded battery charging algorithms are often higher than LiFePO4 requirements, which will result in the BMS disconnecting the battery at the end of the charge cycle, and may result in the charger displaying an error code. If this happens, it is generally good practice to replace your charger. Since the BMS protects the battery, using lead-acid chargers will not damage the battery.

 

HOW TO CHARGE A LIFEPO4 BATTERY IN THE COLD?

LiFePO4 batteries can safely charge between 0°C to 45°C (32°F to 113°F). If your application requires you to recharge in freezing temperatures, Canbat Low Temperature series (LT) can be recharged between -20°C to 45°C (-4°F to 113°F). The LT series has a built-in heating system featuring proprietary technology that draws power from the charger itself. No additional components are required. The entire process of heating and charging is completely seamless. The heating system automatically activates once charging below 0°C is attempted, and it automatically deactivates when it’s no longer needed. The heating system does not take power from the battery, but rather from the charger, ensuring the battery is not discharging itself. Simply plug the battery into the lithium charger and the internal heating and monitoring systems take care of the rest.

 

DO I NEED A SPECIAL CHARGER FOR LITHIUM?

The short answer is no. In order to fully charge a 12V LiFePO4 battery, a charger with a voltage of 14V to 14.6V is required. Most AGM battery chargers are within that range and they would be compatible with Canbat lithium batteries. If you have a charger with a lower voltage, it may still charge the battery, but it won’t charge it to 100%. A charger with a higher voltage would not charge the battery and the BMS would enter protection mode due to its high voltage disconnect feature. Although many AGM battery chargers are compatible with LiFePO4, wet cell or flooded battery chargers are not compatible as they typically charge at a higher voltage.

 

CAN I FULLY DISCHARGE A LITHIUM BATTERY?

Canbat LiFePO4 batteries can be discharged up to 100% of their capacity. However, to optimize the performance of your LiFePO4 battery, to achieve a higher cycle life, and to avoid the BMS disconnecting the battery, we recommend limiting the discharge to 80%. If the BMS disconnects the battery due to low voltage, at 100% depth of discharge, remove the load and recharge using a LiFePO4 charger to reactivate the BMS.

 

CAN LITHIUM DISCHARGE IN COLD TEMPERATURES?

LiFePO4 batteries can safely discharge between -4°F to 140°F (-20°C to 60°C). All Canbat LiFePO4 batteries come with a built-in BMS that protects the battery from low-temperatures and high-temperatures. If the BMS disconnects due to cold or high temperature, wait until the temperature is more suitable and the BMS will reconnect automatically.

 

HOW DO I STORE LITHIUM BATTERIES?

It is recommended to store LiFePO4 batteries at about 50% state of charge (SOC). If the batteries are stored for long periods of time, cycle the batteries at least every 6 months. Do not store batteries that are discharged. They do not require a trickle charger. · Recommended storage temperature: -5 to +35°C (23 to 95 °F) · Storage up to 1 month: -20 to +60°C (4 to 140 °F) · Storage up to 3 months: -10 to +35°C (14 to 95 °F) · Extended storage time: +15 to +35°C (59 to 95 °F) It is highly recommended to store lithium batteries indoors during the offseason.

 

CAN I CONNECT 12V LITHIUM IN SERIES?

Yes, you can connect up to four 12V batteries of the same model in series to obtain a higher voltage. Do not connect lithium batteries in both parallel and series simultaneously. Please note that the 24V lithium batteries are designed for 24V applications and do not support series connections. Likewise with the 36V and 48V lithium batteries. When charging LiFePO4 batteries in series, it’s recommended to use a multi-bank battery charger that can charge each battery individually. If that’s not an option, you can also use a 24V battery LiFePO4 charger or a 48V battery LiFePO4 charger if you’d like to charge your system as a whole. Canbat lithium batteries support charging in series.

 

CAN I CONNECT 12V LITHIUM IN PARALLEL?

Yes, you can connect up to four 12V batteries of the same model in parallel to obtain a higher capacity. Do not connect lithium batteries in both parallel and series simultaneously. Canbat 24V and 36V lithium batteries also support up to 4 units in parallel. Canbat 48V LiFePO4 batteries support up to 14 units in parallel as they are designed for larger projects. Canbat lithium batteries support charging in parallel.

 

CAN I INSTALL A LITHIUM BATTERY ON ITS SIDE?

Yes, Canbat LiFePO4 batteries can be installed upright or on their sides. Please fasten the battery if installed in a moving vehicle, such as in an RV or a boat. Please also avoid placing anything over the battery, and it’s recommended to cover the terminals with a plastic cap to prevent an external short circuit.

 

ARE LIFEPO4 BATTERIES SAFE?

Yes, LiFePO4 is a safe chemistry and the most stable lithium-type battery on the market. Canbat lithium is UL 1642 certified, which means they have been tested for short-circuit, abnormal charging, crush, impact, shock, vibration, heating, temperature cycling and pressure. All Canbat LiFePO4 batteries come with an internal Battery Management System. The BMS protects against

  1. Under-Voltage – during discharge
  2. Over-Voltage – during charge or regen conditions
  3. Over-Current – during discharge
  4. Low-Temperature – during charge and discharge
  5. High-temperature – during charge and discharge
  6. Short-Circuit Protection – protects battery cells from damage
  7. Single Cell Equalization and balancing

There are three main types of lithium-ion batteries (li-ion): cylindrical cells, prismatic cells, and pouch cells. In the EV industry, the most promising developments revolve around cylindrical and prismatic cells. While the cylindrical battery format has been the most popular in recent years, several factors suggest that prismatic cells may take over.

Because Laserax provides laser solutions for battery manufacturing, we are watching these developments closely. Before we go over what’s coming, let’s do a quick overview of the two types of batteries.

What Are Prismatic Cells

EVE Energy  prismatic cell is a cell whose chemistry is enclosed in a rigid casing. Its rectangular shape allows efficiently stacking multiple units in a battery module. There are two types of prismatic cells: the electrode sheets inside the casing (anode, separator, cathode) are either stacked or rolled and flattened.

For the same volume, stacked prismatic cells can release more energy at once, offering better performance, whereas flattened prismatic cells contain more energy, offering more durability. 

Prismatic cells are mainly used in energy storage systems and electric vehicles. Their larger size makes them bad candidates for smaller devices like e-bikes and cellphones. Therefore, they are better suited for energy-intensive applications.

Prismatic cells are much larger than cylindrical cells and hence contain more energy per cell. To give a rough idea of the difference, a single prismatic cell can contain the same amount of energy as 20 to 100 cylindrical cells. The smaller size of cylindrical cells means they can be used for applications that require less power. As a result, they are used for a wider range of applications. 

EVE Energy  specializes in battery design, production, marketing and services in many different industry sectors, such as Telecom Base Stations, AGV, RV, E-Forklift, E-Sweeper, Golf Carts, Golf Trolley, Gardering Machine, Boats, Cleaning Machine, Solar Energy Storage and so on. We are so familiar with all these projects because we`ve work on them for years.

Size

Many of project purchasers and the project development engineer are meeting various problems when they work with the battery selecting and sourcing, such as short cycle life caused by cell differences, terrible heat cooling management, slow and poor developing ability of a more functional BMS, difficulties of integrating BMS and other parts by communication protocol and on. We are deeply aware of all these existing problems, along with the market growing, lithium batteries are solution engineering require much better engineer team than many other products. EVE Energy  were built to solve this problems for you, and save much of money and energy of sourcing a reliable lithium battery products.

Connection 

Because prismatic cells are larger than cylindrical cells, fewer cells are needed to achieve the same amount of energy. This means that for the same volume, batteries that use prismatic cells have fewer electrical connections that need to be welded. This is a major advantage for prismatic cells because there are fewer opportunities for manufacturing defects. 

Power

Cylindrical cells may store less energy than prismatic cells, but they have more power. This means that cylindrical cells can discharge their energy faster than prismatic cells. The reason is that they have more connections per amp-hour (Ah). As a result, cylindrical cells are ideal for high-performance applications whereas prismatic cells are ideal to optimize energy efficiency. 

Example of high-performance battery applications include Formula E race cars and the Ingenuity helicopter on Mars. Both require extreme performances in extreme environments.

The EV industry evolves quickly, and it’s uncertain whether prismatic cells or cylindrical cells will prevail. At the moment, cylindrical cells are more widespread in the EV industry, but there are reasons to think prismatic cells will gain in popularity. 

Why Prismatic Cells Might Be Taking Over

First, prismatic cells offer an opportunity to drive down costs by diminishing the number of manufacturing steps. Their format makes it possible to manufacture larger cells, which reduces the number of electrical connections that need to be cleaned and welded. 

Prismatic batteries are also the ideal format for the lithium-iron phosphate (LFP) chemistry, a mix of materials that are cheaper and more accessible. Unlike other chemistries, LFP batteries use resources that are everywhere on the planet. They do not require rare and expensive materials like nickel and cobalt that drive the cost of other cell types upward.

There are strong signals that LFP prismatic cells are emerging. In Asia, EV manufacturers already use LiFePO4 batteries, a type of LFP battery in the prismatic format. Tesla also stated that it has begun using prismatic batteries manufactured in China for the standard range versions of its cars.

The LFP chemistry has important downsides, however. For one, it contains less energy than other chemistries currently in use and, as such, can’t be used for high-performance vehicles like Formula 1 electric cars. In addition, battery management systems (BMS) have a hard time predicting the battery’s charge level. 

When it comes to battery pack production demand, energy storage systems (ESS) are just as important as electric vehicles. ESSs are already using prismatic cells and it is very likely that they will keep using them. Prismatic cells have a longer cycle life, are less dangerous, and come at a low cost compared to cylindrical cells. You can watch this video to learn more about the LFP chemistry and why it is gaining in popularity.

Prismatic Cells in Energy Storage Systems 

When it comes to battery pack production demand, energy storage systems (ESS) are just as important as electric vehicles. ESSs are already using prismatic cells and it is very likely that they will keep using them. Prismatic cells have a longer cycle life, are less dangerous, and come at a low cost compared to cylindrical cells.
The Switch to Prismatic Batteries
With its tabless cell design, high energy density, and low manufacturing cost, Tesla’s 4680 cylindrical cell is probably the most noteworthy battery cell at the moment. But recently, Elon Musk has talked about the advantages of prismatic cells, and Tesla has begun using them in certain car models. 
The 4680 cylindrical cells haven’t been replaced by prismatic cells yet, but Tesla’s next move will be telling of what the future holds. Will they replace the 4680’s Nickel-Cobalt-Aluminum oxide (NCA) chemistry with the LFP chemistry? If so, will they switch to prismatic cells, the preferred format for this chemistry? With the increased cost of raw materials around the world, it is a strong possibility.
The Life Span
Overall, due to the different manufacturing processes, the cylindrical type will have slightly more cycles than the prismatic LiFePO4 cell.
Weight
Cylindrical cells will be heavier because most of them have steel shells. Prismatic cells are lighter because most of them use stainless steel and aluminum shells.
Manufacturing Cost
Because cylindrical cells have a long history and simpler processing and production technology, the manufacturing cost will be relatively cheaper, while prismatic cells are relatively new, and due to the limitations of processing technology and no special standardized production specifications, So the manufacturing cost will be higher.
Damage Cost
In a battery pack composed of cylindrical cells, if one cell is damaged, it will not seriously endanger the entire battery pack. At the same capacity, damage to a prismatic cell will seriously affect the entire battery pack, which means that the cost of damage is high.
Easy to Expand
Since most scenarios currently require large-capacity batteries, the option of capacity expansion has become a consideration for many people. Relatively speaking, it is more difficult to expand the capacity of cylindrical cells. Under the same capacity, cylindrical cells may need tens of thousands of cells, but prismatic cells may only need a small number, which means that prismatic cells may require only a few cells. The expansion of prismatic LiFePO4 cells is simpler.
Differences in Chemical Activity
Due to the internal structure and shape of the cylindrical cell, the electrolyte distribution inside the cell is very uniform, which is conducive to full utilization. In the inner corners of the prismatic cell, some electrolytes will be in an idle state, and the prismatic structure will exert a certain pressure on the corners. A simple summary is that the utilization rate of the electrolyte will be relatively low.
Heat Dissipation
Cylindrical cells will have better heat dissipation, because there is no way to arrange them as closely as prismatic cells, and there will be gaps between the cells, which provide space for heat dissipation.

High Efficiency

LiFePO4 batteries have a flatter discharge curve that holds above 12V for up to 90% of its usage capacity. It consumes an even amount of energy efficiently, allowing for longer use and without significant fluctuations in energy consumption. By contrast, Sealed lead acid batteries increase their consumption rate as they discharge and this consumption rate becomes even greater when SLA batteries hit 50%.
