- General Information
This specification defines the performance of rechargeable LiFePO4
battery pack TB-BL12200F-S108A 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.

constant current, then charge with constant voltage until current
less than 0.02ItA.
"Standard Discharge" means at 25±2℃ discharge to the cut-off
voltage with 0.33C current.
"Quick Discharge" means discharge to the cut-off voltage with 0.5C
current.

Testing method |
4.1 |
Rated Capacity |
200Ah | 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 120 minutes, you can stop and define the Discharging
current*time value (Ah) as battery capacity. |

Internal resistance |
≤20mΩ | 50% battery SOC state frequency of 1 KHZ ac resistance tester |
4.4 |
Cycle life (DOD100%) |
≥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 full charged capacity is no more than
80% of normal value. Accumulated times is defined as cycle life. |
