48V 13S Universal Ebike battery BMS with small size for Hailong/tigershark/new-polly case

48V 20A/25A 13S BMS/PCM for e-bike downtube batteries. This BMS is with small dimension(L80*W60*T10mm) with balance, ON/OFF switch, battery capacity LED and high temperature protection.

This battery management system(BMS) is suitable for most frame batteries, such as Hailong-02/03 casing battery, DA-5C Casing battery, DS-6 casing battery or new Polly DP-6 casing battery.

If your battery case has 5V USB output, you may also need to order a 5V PCB for your battery.

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.
