110mAh LiPo Battery Test

We want to check the capacity of the an 110mAh LiPo battery for a low drain application.  We'll discharge the battery to a 7.5KOhm resistor for about 5mA load and recharge it at 100mA.  

The battery weighs 3.11g (w/ connector), dimension 1.1 x 0.5 x 0.22", connector JST.



Discharging

Charging 

The kink is caused by switching from constant current (100mA) to constant voltage (4.2V) charging.
