Dears:
Could you kindly help to check the below schematic for 20 series batteries(BMS).
Since sometime the chips' temperature will be higher and can not touch it( there is no pattern to confirm which one.) Or there will have pressure drop of more than 1V on R77 and R100 or R145 and R168.
And weld a new chip the board is OK.
Pls. give us some advice, thanks~
