JNFN Bluetooth 4S BMS Balancing Board 420 A Continuous 1050 A Peak Screw Terminals for Li-ion LiFePO4 LTO and Na-ion Yellow for E-bikes and Scooters
You already have the maximum available quantity in your cart.
The JNFN Balancing BMS Board is designed for the management and protection of batteries in a 4S configuration, meaning it has 4 cells in series, with a very high current draw. The board is rated for a continuous current of 420 A and can briefly withstand a peak of 1050 A. It is equipped with Bluetooth connectivity and a cell balancing function. The power wires connect to screw terminals directly on the board. It can be used in batteries for e-bikes and electric scooters.
- 4S Configuration: the board is designed for batteries with 4 cells connected in series.
- Continuous Current 420 A: compare this value with the maximum current draw of the motor and controller before installation.
- Peak Current 1050 A: the board can briefly handle peak loads of up to 1050 A.
- Screw Terminals: three B- screw terminals and three C- screw terminals are used to connect power wires. Choose the cable cross-section according to the current load of the battery.
- Bluetooth: wireless connectivity allows communication with the board without the need to connect a cable.
- Cell Balancing: the function balances the voltage between individual cells of the battery.
- Types of Cells: the board is suitable for Li-ion, LiFePO4, LTO and Na-ion batteries.
- Temperature Inputs: the connector labelled NTC T1/T2 is used to connect temperature sensors for monitoring the battery temperature.
- B- and B+ Connectors: connectors on the upper edge of the board are used to connect wires to individual cells.
- UART/SW Port: connector in the upper right corner of the board for data communication and additional connections.
- Mounting Brackets: brackets with holes in the corners of the board allow for mounting in the battery box.
- Design: yellow board with JNFN branding.

- 1x JNFN 4S 420 A Balancing BMS Board
The JNFN Balancing BMS Board is designed for the construction or repair of a battery with 4 cells connected in series and a very high current draw. The continuous current of 420 A with a peak of 1050 A should be compared with the needs of the specific drive. The board supports Li-ion, LiFePO4, LTO and Na-ion cells and, thanks to the NTC inputs, allows monitoring of the battery temperature. Bluetooth connectivity and the balancing function complement its protective features. The screw terminals allow the use of power cables with a cross-section appropriate to the load.
