1. General Information


This specification defines the performance of rechargeable LiFePO4 battery pack TB-BL1250F- S110A 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.

3.Electrical Characteristics & Test Condition


Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%


NO Items Criterion Condition
1 Internal Impedance ≤20mΩ

Test the internal resistance of 50% SOC battery pack with 1 kHz AC internal resistance test instrument.

2 Capacity ≥49Ah

Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the discharge cutoff voltage.


Repeat above process for three times, if the discharge time is not less than 180 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.





Cycle life (DOD%100)


Discharge with the current of 0.5C 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 full charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.




Discharge Temperature


-20℃ ≥70%

At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage.


Record the ratio between discharging & charging capacity.

0℃ ≥80%
25℃ 100%
55℃ ≥95%
5 Charge Retention ability remain capacity≥90%


Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.


4. Circuit Protection


The batteries are supplied with a LiFePO4 Battery Management System (BMS)that can monitor and optimized each single prismatic cell during charge & discharge, to protect the battery pack overcharge, over discharge, short circuit. Overall, the BMS helps to ensure safe and accurate running.


Test item Content Criterion
