1kHz AC 2.56KWh 250A Discharge LiFePO4 RV Battery 12V 200Ah

1. Accurately monitor battery SOC to prevent damage from overcharge and overdischarge, Over current / over temperature / low temperature protection, multi-stage fault diagnosis protection ;

2. Single cell Balanced Charging, Balanced and consistent state of each cell in the battery pack

3. The charge or discharge of the battery is managed according to the state of the environment and the battery state, with the best charge or discharge curve of the battery


1. General Information

This specification defines the performance of rechargeable LiFePO4 battery pack TB-BL12200F-SC-M110X manufactured by SHENZHEN TOPBAND BATTERY CO.,LTD, describes the type, performance, technical characteristics, warning and caution of the battery pack. The battery pack support Bluetooth communication function. Through Android and IOS APP, can read the battery status and information. Especially due to the Android system’s openness, different smart phone manufacturer will have their own different Bluetooth hardware version and customized feature Android systems. So the APP may not work well on some smart phones(with Android system) due to compatible issue. It is necessary for the customer to confirm whether the phone is compatible for the APP.
