    1. About us


    Shenzhen Topband Battery Co., Ltd, a company professional to do LiFePO4 battery, which is founded in 1996 and listed in Shenzhen in 2007. There are over 300 R&D engineers and about 3,000 employees in the 70,000 square meters Topband industrial park. We can provide One -Stop Solution of new energy, from cell, BMS/PCM to battery pack assembling.


    This rechargeable LiFePO4 battery pack TB-BL1220F-S115D supports 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. It is necessary for the customer to confirm whether the phone is compatible for the APP.

    3. Test conditions


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

    Normal charge:Charge battery under CC(0.33C)/CV(43.8V) mode until over charge protection or the charge current reduce to 0.05C, and then rest for 1h.


    4. Product Performance


    NOItemsCriterionCondition
    1Internal Impedance≤50mΩTest the internal resistance of 50% SOC battery pack with 1 kHz AC internal resistance test instrument.
    2Capacity≥20AhRest 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.
