I have the 10S 40A model and mounted dissasebled, choose this model instead the 30A one because this one have 2 more MOSFET and has the same dimensions, the overcost is 1-2€. Each mosfet can handle 250W max. A 10K NTC can be installed once case is removed and makes cut off at about 72ºC but; --> IMPORTANT --> Once the NTC installed there is a voltage drop of 0,4V when the temperature reach 39ºC and more, i tested it with a 10K potentiometer, voltage drops 0,4V at 5,74K ohm on the NTC input. There is a current spark when you connect the cahrger, no matter if the soft swiych is off.

it's good that you dismantled this bms, how many are its dimensions, length, width, height when disassembled? I want to buy.
77,2 x 58,5 x 7,5 mm
Thas the size without the 11pin connector, i removed it
it looks cheap , also a very discrete heavy build , maybe it was cheaper
also that is not am MCU it is some cheap analogue chip
