1. General Information
This specification defines the performance of rechargeable LiFePO4 battery pack TB-BL12150F-SC-S110A 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, it can read the battery status and information. 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.

9. Battery operation instruction
Charge and discharge
1. Charging current: Do not surpass the largest charging current that specification stipulated.
2. Charging voltage: Do not surpass the highest limited voltage that specification stipulated.
3. Charging temperature: Within temperature scope that specification stipulated.
4. Charge with constant current, then with the constant voltage, no reverse charge, which is dangerous1
5. Special note: Short time doesn't affect the use of the battery overcharge too, but for a long period of time over discharge or over charge can affect the function of the battery failure, or the battery can't use permanent, appear serious safety hazards, and need longtime floating please use the recommended floating model specification. Battery when not in use for a long time, because of its own self-discharge characteristics can also cause discharge, to prevent the occurrence of a discharge, the battery should maintain a certain capacity; maintain the voltage at 50% state of SOC.
10. Other Chemical Reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges, the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the discharge time is much shorter than the normal after fully charged, even battery is charged correctly, and this may indicate it is time to change the battery.
