Charge Small LiPo Batteries. This charger has a customized resistor to provide a 40 mA charge rate. This is suitable for small LiPo batteries such as 40 mAh.

Charge Large LiPo Batteries. Use appropriate pin settings for charging larger LiPo batteries. A rule of thumb is that the charge rate should be 50% to 100% of the battery capacity. For example, a 100 mAh Lipo should have a charge rate of 50 to 100 mA.
