JNFN S Bluetooth 4S 130 A Peak 325 A NTC Inputs Balance BMS Board 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 balance BMS board is designed to manage and protect the battery in a 4S configuration, meaning it has 4 cells connected in series. The board is rated for a continuous current of 130 A and can briefly withstand a peak of 325 A. It is equipped with Bluetooth connectivity and cell balancing functionality. It can be used in the batteries of e-bikes and electric scooters. The power wires are terminated with cable lugs, and the connectors on the top edge are clearly labelled.
- 4S Configuration: the board is designed for batteries with 4 cells connected in series.
- Continuous Current 130 A: compare this value with the maximum draw of the motor and controller before installation.
- Peak Current 325 A: the board can briefly handle peak loads of up to 325 A.
- Bluetooth: wireless connectivity allows communication with the board without the need to connect a cable.
- Cell Balancing: the function equalises the voltage between individual cells of the battery.
- Cell Types: the board is designed for Li-ion, LiFePO4, LTO and Na-ion batteries.
- Temperature Inputs: the connector labelled NTC T1/T2 provides NTC T1 and T2 inputs for connecting temperature sensors that monitor the battery temperature.
- B- and B+ Connectors: connectors on the top 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.
- Power Wires: a pair of blue B- wires and a pair of black C- wires, each terminated with a cable lug for bolting to the battery and output. The colour coding helps prevent polarity confusion.
- Mounting Brackets: brackets with holes in the corners of the board allow for bolting in the battery box.
- Finish: yellow board with JNFN branding.

- 1x JNFN 4S 130 A balance BMS board
The JNFN balance BMS board is designed for building or repairing a battery with 4 cells connected in series and high current draw. The continuous current of 130 A with a peak of 325 A should be compared with the requirements 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 balancing functionality complement its protective role. The power wires with cable lugs simplify the connection to the battery.
