Lithium Battery Description:

It is an 824070 2S 7.4V 2300mAh lithium polymer battery pack. It is series by 2 pieces 824070 cell. Its rated voltage is 7.4V.

The landing page is about 2S 7.4V 824070-2300mAh battery pack. 824070 refers to thick 8.2mm, width 40mm, length 70mm. As it is 2 series battery pack, it shall 2 cells layout into one battery pack. So its thick will be 14mm. After soldering PCM, the length will be increased 2~3mm. So that’s basic lithium polymer battery dimension explanation.

General performance:

0.2C Capacity
Test methods and condition: After standard charging, laying the battery 5min, then discharging at 0.2C to voltage 9.0V, recording the discharging time.
Criteria: ≥300min

1.0C Capacity
Test methods and condition: After standard charging, laying the battery 5min, then discharging at 1C to voltage 9.0V, recording the discharging time.
Criteria: ≥57min

Cycle Life
Test methods and condition: Constant current 0.5C charge to 12.6V, then constant voltage charge to current declines to 0.01C, stay 5min, constant current 0.5C discharge to 9.0V, stay 10min. Repeat above steps till continuously discharging capacity higher than 80% of the initial capacities of the cells
Criteria: ≥300 times
