14S 30A BMS/PCM for 52V new polly downtube casing battery for Bafang BBSHD kit

52V 30A 14S BMS/PCM for e-bike downtube new polly DP-6 casing batteries. This BMS is designed for new Polly DP-6 casing battery with only 8mm in thickness which enables building larger capacity with this case;

The BMS has balance, ON/OFF switch, and high temperature protection.

Continuous discharging current to be 30A, fit for Bafang BBSHD kit.

If your battery case does not have ON/OFF switch, please short circuit the ON/OFF switch wires when assemble the BMS to your pack.

14S 30A BMS for 52V ebike new downtube polly DP-6 casing battery(14S5P) with large current and small dimension.
