JK BMS Smart — Active Balancer Battery Management Systems

JK BMS (JiKong) smart boards combine protection and active balancing on a single PCB, which is why they are the default choice for DIY LiFePO4 storage banks and EV packs. Every unit supports Bluetooth monitoring through the JK app, giving you live cell voltages, temperature, current and state of charge without extra hardware.

Amcell stocks JK BMS in common 4S, 8S, 16S, 20S and 24S configurations with continuous current ratings for both home energy storage and traction use.
