I bought a cheap BMS module for my headway LiFePo4 cells which was supposed to balance the cells and protect from over current charge and discharge.
It didn't, but instead fried two of my headway cells and one of it's own power mosfets. Looking up the mosfet number it was a obsolete Toshiba part and unobtainable at a reasonable price if at all. The datasheet shows that it's only available as a through hole TO-220 package, but the one on the board is surface mount. My question is, can you perform surgery on a TO-220 mosfet, removing the center leg and grinding away much of the heatsink and use it as a surface mount component as this seems what has been done on the BMS board?
