1. General Information

This specification defines the performance of rechargeable LiFePO4 battery pack TB-BL12300F-SC-S106B 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.

4. Product Performance

NO. Items Criteria Testing method
4.1 Rated Capacity 300Ah Rest for 1 hour after fully charged, then discharge with 0.5C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 120 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.
4.2 Minimum Capacity 288Ah
4.3 Internal resistance ≤20mΩ 50% battery SOC state frequency of 1 KHZ ac resistance tester

Cycle life


≥2000cycle Discharge with the current of 0.33C until it can’t discharge, and then rest it for 1h. Charge the battery following CC (0.33C)/CV (14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until fully charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.

Discharge Temperature
