You already have the maximum available quantity in your cart.
The JNFN balancing BMS board is designed for the management and protection of the battery in an e-bike or electric scooter with a higher voltage. It is intended for batteries configured in 17S to 24S, meaning with 17 to 24 cells in series. The board is rated for a continuous current of 50 A and can briefly handle a peak of 125 A. Features include Bluetooth connectivity and cell balancing functionality. Connectors on the top edge and power wires on the sides are clearly labelled.
- For 17S to 24S: the board serves batteries with 17 to 24 cells connected in series, thus higher voltage assemblies.
- Continuous current 50 A: compare this value with the maximum consumption of the motor and controller before installation.
- Peak current: the board can briefly withstand a peak of 125 A.
- Bluetooth communication: wireless connection allows communication with the board without the need to connect a cable.
- Cell balancing: this function equalises the voltage among the individual cells of the battery.
- Compatible cells: the board is designed for Li-ion, LiFePO4, LTO and Na-ion batteries.
- UART/SW data connector: located in the top left corner of the board, used for data communication and additional connections.
- Cell connectors: two connectors labelled B- and B+ on the top edge of the board are used to connect wires to the individual cells.
- Power wires: the blue wire B- and the black wire C- ensure the power connection. Colour coding helps prevent confusion during installation.
- Mounting brackets: brackets with holes on both sides of the board allow for screwing into the battery box.
- Yellow finish: the board features the JNFN brand printing.
Contents of the package:
- 1x JNFN balancing BMS board 17S to 24S 50 A
The JNFN balancing BMS board is suitable for building or repairing a battery for an e-bike or electric scooter with 17 to 24 series cells. The continuous current of 50 A with a peak of 125 A needs to be compared with the consumption of the specific motor and controller. The board supports Li-ion, LiFePO4, LTO and Na-ion cells, making it usable in various battery packs. The Bluetooth connection and balancing function complement its protective role. Before installation, ensure that the number and type of cells and the current draw match the specifications of the board.
