* Board is using DW01-P Chip to control the cells with 2x FS8205A MOSFETs. I found the datasheets and put them above.
* After connecting the cells may need to connect the charger to activate the board
* Before connecting cells in parallel, equalize the voltage with 1 ohm resistors between. May need from few minutes to few hours.
* Have fun!
