Quick Overview

This is a smart BMS which can be used for either Li-ion batteries or LiFePO4 batteries. It can use for 9S to 15S batteries. Some customers seeks for 13S LiFePO4 BMS, 14S Li-ion PCM, this BMS is the one you are looking for.  You can program it 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) when outside. The BMS has been upgraded with alloy plates for better heat radiation, but the connection of the PCM has no changed. If you need the bms communication software, app and connection diagram, please download from here.



Li-ion/LiFePO4 programmable BMS 9S-15S, you can use it for 9S, 10S. 11S. 12S, 13S, 14S and 15S Li-ion or LiFePO4 batteries. You can set the parameters via company and yo can also check parameters on your phone.
