2S charger (test)

Overview

2s lithium battery balance charging. TP5000
20200825: The TP5000 charging daughter board did not work properly after testing. The problem has not been found. It is recommended to buy the finished product directly. (General price is 3.5 yuan per piece)
20200826: The original plan to use a flyback power supply to convert 12V to 5V was too low, only about 50% efficient, and the mos generated serious heat, so the plan was to use a push-pull circuit instead.
