Lithium battery smart BMS is a management system tailored for large capacity series lithium battery packs. It has the functions of voltage collection, active balancing of large current, overcharge over-current over-temperature protection, Coulombmeter, Bluetooth communication, GPS remote and so on. It is suitable for lithium iron phosphate, lithium ternary and other battery types. 
The BMS relies on our Proprietary technology for Active Balancing. Our high current active balancing technology can ensure maximum battery consistency, improve battery life, delay Battery aging. The BMS has a companion mobile APP that supports Android V. 7 and above and IOS operating systems. The APP can connect to the BMS via Bluetooth on your mobile phone to check the battery working status and to modify the working parameters of the BMS, control the charging, discharging switches, and so on. The BMS is small in size, simple to operate and full of functions, that can be widely used in battery PACK of small sightseeing cars, walkers, shared cars, high-power storage, base station backup power, solar power stations and other products.。
This is essential so that everything is reading, sending/receiving the correct Voltages @ the Battery Terminals / DC Bus (for Parallel Banks of Batteries).
 When an SCC or Inverter/Charger etc is charging @ 25.6/51.2 You need to ensure that is WHAT the Batteries See. Otherwise, the differential "will" cause a Mismatch and generate an error (*1), either at the SCC or any Charge Device on the DC Bus (*2).
 The BMS is the MOST Precise @ measuring the Battery & the Cell Voltage States. This applies to a Single Battery or a Bank of Batteries.
 Not All SCC's or Charging Devices have a Compensation/Correction setting within them. Therefore you have to do the "Math" to compensate for that differential. Therefore you "must" take Voltage Measurements @ the SCC, Charger & Battery Terminals/Bus, then make adjustments to match your desired Charge Profile to prevent such incidents.
 A Digital Multimeter / Digital Volt/Ohm Meter with at least 2 Decimal Place voltage displays is Most Highly Recommended to do so. A Single Digit device is TOO  NACCURATE for any
Lithium Based Battery or cell.
(*1) This can result in Over/Under voltage reading triggering an error. IF over or under it can also create the "Runner Cell" situation where one or more cells within a Battery can run & defeat the Working Voltage Range (3.000-3.400) of the cells, triggering a BMS Fault. This is Very Common with new/fresh
installations that are NOT Corrected & Balanced for Voltage.
(*2) Note that ALL DC-Lines will suffer some loss over the length of the wire run. These include every terminal, lug, bolt, switch, and even fuses & breakers collectively. While each individual "item" may not be large (unless there is a Fault), collectively they can add up quite quickly collectively. This is an "accuracy" requirement problem with using Lithium Based tech as opposed to Lead Acid which is more "brute force" and not as accurate due to the very Tight Voltage Curves in comparison to Lead-Acid. 
Typical Faults creating large drops, with some basic problem avoidance solutions:
 Loose or dirty connections,
 Poor or weak crimped terminals,
 Overly long wiring, including wires of Different Lengths (+) & (-) should be as close to identical lengths as possible,
 Low-Grade or Incorrect wiring used for the application, load & demands,
 Quality wires (Fine Strand Pure Copper) tinned or not, along with Tinned Terminal lugs is always the best solution,
 All Connections to Lugs etc should be shrink wrapped with quality adhesive bound Shrink
Wrap to prevent air/moisture infiltration over time that can cause corrosion & deterioration. Do NOT avoid using long enough shrink wrap. 
Final Important Note:
It is extremely important to not that various devices like Solar Charge Controllers, Inverter/Chargers etc all have varying hardware, firmware and user interface software. This makes Calibration & Configuration more demanding for proper operations between all the variety of device.

Key Features

he JK-B2A25S-RP battery management system (BMS) is intended for largecapacity (high current and many cells in series) lithium battery packs. It can be configured to operate with other battery types such as ternary lithium, lithium Titanate (LTO) etc.

The system supports 3 to 25 cells connected in series. The JK-B2A25S-RP performs the standard BMS functions i.e. protection against : over/under cell temperature, over charge or discharge currents,

over/under cell voltages In addition the JK-B2A25S-RP also performs an active cell balancing function. Active balancing takes energy from the highest charged cell (cell with highest voltage) and transfers this via a super capacitor to the cell with the lowest voltage.

Being active no energy loss is experienced in the process (passive balancing uses resistors to balance but this creates a lot of energy loss). Balancing happens as long as the BMS is connected to and powered by the

cells. Balancing avoids situations where adjacent cells can be over and under charged (i.e. 3V and 3.6V iso both being 3.3V) Balancing (after enough time to perform the function) maintains the cell

voltages withing 5mV to 10mV (adjustable) from each other. Balancing improves the available capacity and the overall lifespan of the battery. Unlike smaller capacity BMS units, the JK-B2A25S-RP does not include internal semiconductor switching elements to disconnect the battery if a fault condition occurs.

Disconnecting is achieved via externally installed high current solenoids (relays). Depending on the requirement up to 3 of these solenoids might be needed (pre-charge, over charge, over discharge) The solenoids are not supplied with the BMS and these needs to be externally sourced.

The JK-B2A25S-RP has built in Bluetooth support allowing you to set parameters and monitor the status of the cells. A matching Android/Apple App needs to be installed

Specifications Maximum number of supported cells: 25 cells

Minimum number of supported cells: Around 4 if powered by connected cells (12V)

Max Switching Current: This is a function of solenoid. Typically 500A (1000A peak)

Balancing Current: 2A

Battery technologies: LFP, NMC, LTO etc CAN Support: CAN 2.0A. Transmit status messages at 250kbps

Bluetooth Support: Yes | JIKONG BMS App *All product specifications and product images are subject to change without notice. 

Can Bus Operation

The JK-B2A25S-RP has a built in STM32F103 class microcontroller. It supports CAN bus communications as per CAN2.0A standard at 250kbps. The BMS transmits status information only (it does not receive or respond to any messages). The message cycles and ID’s are as follows: 

Packing Information
