1. General Information
This specification defines the performance of rechargeable LiFePO4 battery pack TB-BL1280F-SC-S113A-2301 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.
