350A Relay BMS 4S-35S Peak 2000A For LiPo LiFePO4

The relay BMS can be one of the perfect solution for large vehicle starting power, engineering vehicle, low speed four-wheel vehicle, RV or any other device you want to place it in.

It supports 500A continuous current output, and the peak current can reach 2000A. It is not easy to be heated or damaged. If damaged, the main control will not be affected. You only need to replace the relay to reduce maintenance costs. You can also develop your own application system according to your own needs. We can provide BMS interface communication protocol.

We’ve done several successful solar energy storage project. Contact us if you want to build your high voltage system!
