1. General Information
This specification defines the performance of rechargeable LiFePO4 battery pack TB-BL12100F-M110A_HEAT manufactured by Shenzhen Topband Battery Co., Ltd, describes the type, performance, technical characteristics, warning and caution of the battery pack. The battery pack supports Bluetooth communication function. Through Android and IOS APP, the battery status and information can be read. Especially due to the Android system’s openness, different smartphone manufacturer will have their own different Bluetooth hardware version and customized feature Android systems. So the APP may not work well on some smartphones (with Android system) due to the compatible issue. It is necessary for the customer to confirm whether the phone is compatible with the APP.
