Quick Overview

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.
