48V 13S 30A BMS battery with mini size; it is suitable for Dengfu E22 /E23 /E10 batteries and some of the Dorado batteries.

The BMS has ON/OFF switch if your battery has no switch, just short circuit the two switch wires.

7S BMS(battery management system) for 24V li-ion battery. 

The BMS is small in dimension(65*35*9mm) and it can fit into many battery cases.

It has a high temperature protection sensor which will protect your battery from too hot.

10S, 11S, 12S, 13S, 14S, 15S, 16S, 17S, 18S, 19S, 20S, 21S, 22S Smart battery BMS with computer softwave or mobile(via bluetooth). This Smart BMS is handle max 120A continuous discharging current; if your going to build a smart battery with a case, this small BMS(63x52x12mm, 102x66x10MM, 102x66x17mm or 102 x76x18mm) 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).  If you install the BMS for a 10S battery, and a year later, you want to install it for a 14S, this BMS can fit your requirement. For different strings, only the connection diagram is different, please contact us for the connection diagram if you want to install it for a different battery. 

The BMS has ON/OFF switch and you can activate the switch via the mobile app; The Bluetooth is built in with the BMS which you can install the app on the mobile and check the battery status or change the parameters(IOS can only change a few parameters, please note).

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.  The BMS can identify the battery string as far as the connection is correct.

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
