1) The BMS is designed for 13 series lithium battery.
2) The BMS have all functions which are :
Overcharge detection function
Over discharge detection function
Over current detection function
Short detection function
Balance function
Temperature detection
If you are designing new residencial back up power with energy of bigger capacity , you can parelle two or more standard module, we can provide all equipment including of the battery storage charger bms inverter or other compenents such us display unit , romote motering and etc with your require.
