Description
**# Warning!!!!! #**
1.Make it at your own risk.
2.This circuit Has not any current limiting feature.(except 2x 1R3W Resistor)
3.This circuit is not 100% Perfect, but it is still very useful for hobby/DIY projects.
4.Wrong calibration can cause battery explode.Be careful.
5.Use a 5 times lower current value then your battery capacity.
i.e. 200mA. For 1AH Battery.
