Lithium Smart Battery,
Lithium Phosphate Battery
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-BL12125F 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. 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%.
|1||Capacity||≥125Ah||Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the cutoff voltage. you can stop and define the Discharging current*time value (Ah) as battery capacity.|
Cycle life (DOD%100)
Charge / CC(0.33C)/CV(14.6V);
End current : 0.05C;
Rest time : 1h;
Discharge / CC(0.5C);
End voltage : 8.0V;
Repeat above process until discharge capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.
|-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.|
|4||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. New function
It's available to add Bluetooth tool for monitoring battery feature from smart phone as following:
5. Dimensional Drawing
6. Storage and Transportation
1) Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
2) Battery should be stayed in the ware house -20℃～35℃ where it’s dry, clean, shade, and well-ventilated.
3) The battery should be stored in 50% SOC during transportation.
4) The battery need to be charged every 6 months if out of use
5) Keep the battery against dropping, turning over and serious stacking during loading.
7. Warning & Tips
Please read and follow the specification and caution remarks on battery surface before use the battery. Improper use may cause heat, fire, rupture, damage or capacity deterioration of the battery. Shenzhen Topband Battery Co., Ltd. Describes is not responsible for any accidents caused by the usage without following our specification.
