48V 13S 20A battery BMS with small size(65*35*10MM) for ebike downtube batteries, Hailong batteries, Jumbo shark batteries or Dorado batteries.

Note, this BMS is only suitable for 48V/13S li-ion battery; it is not suitable for LiFePO4 battery.  

The continuous discharge current is 20A, pulse/max discharging current is 50A; The max charging current is 5A.  

If you use this BMS for Dorado battery, please short circuit the switch wires.

If you are looking for larger current BMS,you can order order this one for you battery: 48V 13S BMS for downtube battery.

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.

12S BMS for 3.2V Lifepo4 battery pack, continous discharge current being could be 30A,  pulse/peak discharge current being 80A, suitable for 12S(36V) LiFePO4, phosphate battery and li-ion battery;

The BMS has 90 degree temperature protection sensor.

20S, 24S, 60V/72V /84V lihtium-ion/LiFePO4 BMS/PCM with balance for e-motorcycle 30A,40A or 50A.

The BMS has short circuit, overvoltage/undervoltage protection, over current protection etc.

COMMON port means charging and discharging use the same port.

Separate port means charging and discharging use separate port.

There balance LED on the BMS which you can check if the cells are in balance or not, or you can find the "defective" cells which are not in balance status.

17S 30A 40A 50A BMS /PCM, Battery management system for 60V Li-ion battery, continuous discharge current could be 30A, 40A or 50A, peak/pulse discharge current could be 100A. 

Common Port can handle large charging current; separate port would be with smaller charging current(5A~10A, please refer to detail information on our website);

This BMS has LED for balance, you will get to know which cells are in balance status and which cells are not in balance status.

Smart lihtium battery management system/PCM for 12S, 13S, 14S or 15S Lithium LiFePO4, NiCoMn, LiMn2O4 etc diy battery packs. You can program the intelligent BMS/lithium battery on your computer and view all the parameters via your mobile(The Android APP can slightly modify parameter for the BMS while the IOS APP can only read datas and cannot modify data from mobile). Our ltihium battery BMS has been upgraded with alloy plates for better heat radiation, but the connection of the PCM has no changed.  We also provide smart BMS with larger serial from 7S~10S, 11S~15S(current less than 60A), 16S~ 20S PCM and 20S~ 30S BMS with software and mobile app control. 

The PCM is with blanace, standard UART COM, Short circuit protection, temperature(NTC) protection, overcharge protection, overdischarge protection, over current protection and under voltage protection etc.  Some Smart BMSs are available for RS232 and RS485 COM port, please email us if you need.

This smart BMS use the same COM for charging and discharging which means the max charging current could be larger. If you  need a battery charger for your diy packs, we also provide customized lihtium battery chargers.
