1. General Information
This specification defines the performance of rechargeable LiFePO4 battery pack TB-BL12300F -S107A_HEAT 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.

"Standard Charge" means at 25±2℃ charge to limit voltage with 0.33C constant current, then charge with constant voltage until current less than 0.02C.
3.3 Quick Charge Mode
"Quick Charge" means at 25±2℃ charge to limit voltage with 0.5C constant current, then charge with constant voltage until current less than 0.02C.
3.4 Standard Discharge Mode
"Standard Discharge" means at 25±2℃ discharge to the cut-off voltage with 0.5C current.
3.5 Quick Discharge Mode
"Quick Discharge" means discharge with 0.67C current withstand 30 mins.
4. Product Performance
|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.|
|4.3||Internal resistance||≤30mΩ||50% battery SOC state frequency of 1 KHZ ac resistance tester|
|≥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.|
|-20℃||≥70%||At 25±5℃ discharge the battery with the current of 0.5C to the cut-off voltage and record charge capacity. Store the battery at various temperatures for 2h and discharge the battery with 0.5C to the cut-off voltage.|
|4.7||Charge Retention ability||
|Charge the battery to full capacity and store it for 28days, and then discharge it with 0.5C to the cut-off voltage.|
