I am trying to replace my drill's nicad batteries with Lithium\BMS.
I ordered a bunch of BMS but upon soldering, I get several problems such as the bms is draining a battery(different battery(1-5) on different BMS), or the power out will read 20v but as soon as I give it a load and squeeze the trigger, the voltage drops to 0v(the whole time the battery still reads 20v.
SO... I just bought a new drill of higher watts to speed up the soldering. It is not like I leave the soldering iron on the board and I am sure I am not shorting wires. Being it is hotter than my old solder, will this fry components on the board, or did I indeed get a bunch of lemmons??
TIA.
