Smart battery BMS for 13S /14S(48V/52V) 20A/30A/40A/50A/60A with small size

Availability: Out of Stock


Quick Overview

13S/48V 14S52V battery BMS with computer softwave or mobile(via bluetooth). This Smart BMS is handle max 60A continuous discharging current; if your going to build a smart battery with a case, this small BMS(108X65*10MM) would be suitable for you. You can program the battery from the the computer or view the battery status from your mobile(IOS system can only view battery status while Androi system can slightly modify some parameters).  

The smart BMS adapts UART COM; you cannot connect to the computer or mobile in the same time since it has only one COM; you can connect to the computer set the parameter, save the data, then connect to the bluetooth, view datas fromt the mobile app. 

If you also need a matching charger for your battery, you can choose one battery from here: battery charger; if you don't know what charging current it is, you can leave us a message and we will check for you.

If you need larger discharging current for your battery, we also provide other smart BMS with larger current, you can check from here: 80A-100A 11S-15S smart battery BMS

You can switch ON or OFF the battery via the mobile app. For more functions or details, you can download the software and app from here: smart BMS connection diagram and software
