About the lipo charging circuit problem ( Important update in 10th September 2018 ):
After V2.1-1.5 was upgraded to V2.1-1.6, after our tests, the diode components should be used on the charging circuit, but we used a fuse, the diode is unidirectional, and the fuse is bidirectional. This causes the USB voltage to pass directly to the battery. After a long woking time, the battery may become hot or burn, so you cannot use this V2.1-1.6 version to charge the battery! ! ! (Battery can be used, but the battery cannot be charged) If you want to use this V2.1-1.6 version to charge the battery, you need to replace the fuse in the figure with a diode (Type:?BS5819 SOD123 1A) to use the charging function normally.?The following is an upgraded picture.
