Victron Energy Lithium Battery Smart batteries are Lithium Iron Phosphate (LiFePO4) batteries and are available in 12.8 V or 25.6 V in various capacities. They can be connected in series, parallel and series/parallel so that a battery bank can be built for system voltages of 12 V, 24 V or 48 V. The maximum number of batteries in one system is 20, which results in a maximum energy storage of 84 kWh in a 12 V system and up to 102 kWh in a 24 V1) and 48 V1) system.
A single LFP cell has a nominal voltage of 3.2V. A 12.8 V battery consists of 4 cells connected in series and a 25.6 V battery consists of 8 cells connected in series.
Why lithium-iron-phosphate?
Rugged
A lead-acid battery will fail prematurely due to sulfation:
• If it operates in deficit mode during long periods of time (i.e. if the battery is rarely, or never at all, fully charged).
• If it is left partially charged or worse, fully discharged (yacht or mobile home during wintertime). A LFP battery:
• Does not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of LFP compared to lead-acid.
• Other advantages are the wide operating temperature range, excellent cycling performance, low internal resistance and high efficiency (see below).
LFP is therefore the chemistry of choice for demanding applications.
Efficient
• In several applications (especially off-grid solar and/or wind), energy efficiency can be of crucial importance.
• The round-trip energy efficiency (discharge from 100 % to 0 % and back to 100 % charged) of the average lead-acid battery is 80 %.
• The round-trip energy efficiency of a LFP battery is 92 %.
• The charge process of lead-acid batteries becomes particularly inefficient when the 80 % state of charge has been reached, resulting in efficiencies of 50 % or even less in solar systems where several days of reserve energy is required (battery operating in 70 % to 100 % charged state).
• In contrast, a LFP battery will still achieve 90 % efficiency under shallow discharge conditions. Size and weight
• Saves up to 70 % in space
• Saves up to 70 % in weight
Expensive?
• LFP batteries are expensive when compared to lead-acid. But in demanding applications, the high initial cost will be more than compensated by longer service life, superior reliability and excellent efficiency.
Bluetooth
• With Bluetooth cell voltages, temperature and alarm status can be monitored.
• Instant readout: The VictronConnect App can display the most important data on the Device list page without the need to connect to the product.
• Very useful to localize a (potential) problem, such as cell imbalance.
1) To reduce required balancing time, we recommend to use a little different batteries in series as possible for the application. 24 V systems are best built using 24 V batteries. And 48 V systems are best built using two 24 V batteries in series. While the alternative, four 12 V batteries in series, will work, it will require more periodic balancing time.
Our LFP batteries have integrated cell balancing and cell monitoring. The cell balancing/monitoring cables can be daisy-chained and must be connected to a Battery Management System (BMS).
Battery Management System (BMS)
The BMS will:
1. Generate a pre-alarm whenever the voltage of a battery cell decreases to less than 3.1 V (adjustable 2.85 V – 3.15 V).
2. Disconnect or shut down the load whenever the voltage of a battery cell decreases to less than 2.8 V (adjustable 2.6 V – 2.8 V).
3. Stop the charging process whenever the voltage of a battery cell increases to more than 3.75 V or when the temperature becomes too high or too low.
See the BMS datasheets for more features.

Enabling a cost reduction, as well as boosting the system’s efficiency
4.Battery management
The battery has an integrated Balancing, Temperature and Voltage control system (BTV). The BTV connects to an external Battery Management System (BMS). In case of multiple batteries, the BTVs of several batteries are daisy chained and then connect to the BMS.
The BMS protects the battery cells against low and high cell voltages and against charging at too low or high temperatures. This is how it works: The BTV monitors each individual battery cell. It balances the cell voltages and in case of high or low cell voltage, or in case of high or low cell temperature, it will generate an alarm signal. The alarm signal is received by the BMS and the BMS will turn off loads an/or chargers accordingly.
A Victron Energy BMS is essential for a correct operation of the lithium battery. The lithium battery is not allowed to be used without one. In addition to this you will also need to ensure that the BMS correctly controls all loads and charge sources that are connected to the battery.
The BMS is not included with the battery. It needs to be purchased separately. For more information on the different BMS types, see chapter The BMS models [7]
5.The VE.Bus BMS V2
The VE.Bus BMS V2 is the next generation of the VE.Bus Battery Management System (BMS). It is designed to interface with and protect Victron Lithium Battery Smart in systems that have Victron inverters or inverter/chargers that have VE.Bus communication and offers new features such as auxiliary power in- and output ports for powering a GX device, remote on/off ports and communication with GX devices.
Just like the smallBMS, it also features a “load disconnect”, a “charge disconnect” and a "pre-alarm" contact.
• In the event of low cell voltage, the VE.Bus BMS V2 will send a “load disconnect” signal to turn off the load(s) and will also disable inverting of the inverter/charger via VE.Bus communication.
• Prior to turning loads off, it will send a pre-alarm signal warning of imminent low cell voltage.
• In the event of a high cell voltage or high/low battery temperature, the VE.Bus BMS V2 will send a “charge disconnect” signal to turn the charger(s) off and it will also disable the charger of the inverter/charger.
A mains detector and a short RJ45 UTP cable ship together with the VE.Bus BMS V2. These are needed for mains detectiononce the inverter/charger has been turned off by the BMS.
6. The VE.Bus BMS
The VE.Bus BMS is used in a system that also contains one or multiple Victron Energy inverter/chargers. The VE.Bus BMS directly communicates via the VE.Bus with the inverter/chargers. Just like the smallBMS, it also features a “load disconnect”, a “charge disconnect” and a "pre-alarm" contact.
• In the event of low cell voltage, the VE.Bus BMS will send a “load disconnect” signal to turn off the load(s) and it will also turn the inverter of the inverter/charger off.
• Prior to turning loads off, it will send a pre-alarm signal warning of imminent low cell voltage.
• In the event of a high cell voltage or high/low battery temperature, the VE.Bus BMS will send a “charge disconnect” signal to turn the charger(s) off and it will also turn the charger of the inverter/charger off.

7.The Lynx Smart BMS
The Lynx Smart BMS is used in medium to large systems that contain DC loads and AC loads via inverters or inverter/chargers, for example on yachts or in recreational vehicles. This BMS is equipped with a contactor that disconnects the DC system, a “load disconnect”, a “charge disconnect”, a "pre-alarm" contact and a battery monitor. In addition to this it can be connected to a GX device and control Victron Energy equipment via DVCC.
• In the event of low cell voltage, the Lynx Smart BMS will send a “load disconnect” signal to turn the load(s) off.
• Prior to turning a load off, it will send a pre-alarm signal indicating imminent low cell voltage.
• In the event of high cell voltage or low/high battery temperature, the BMS will send a “charge disconnect” signal to turn the charger(s) off.
• If the batteries are eve further discharged (or overcharged), the contactor will open, effectively disconnecting the DC system to protect the batteries.

Battery monitoring
The common battery parameters, such as the battery voltage, battery temperature and cell voltages can be monitored via Bluetooth using the VictronConnect app. However, state of charge monitoring is not built into the battery. To monitor state of charge use the Lynx Smart BMS or add a battery monitor such as a BMV or a SmartShunt to the system. If a battery monitor is used together with a lithium battery, adjust the following two settings:
• Set the charge efficiency to 99%
• Set the Peukert exponent to 1.05
For more information on battery monitors see the Battery monitor product page. When a battery monitor is added to the system it matters how the battery monitor is powered. There are two options:
