Just did some digging into the dead Worx 20v pack to see what the deal is with each pin. I think I've got it all figured out but I want to make sure no one else is about to fry there charger on me when they try to use this.
So the most obvious. Is negative and + is positive. Then BH is the battery enable pin, BS is the battery sense / identification pin. Vcc is the logic voltage from the charger. L is the thermistor for the tool to sense temperature, should be NTC thermistor. Finally C1-C4 is the junctions between each battery pack group, for balancing during charge.
I'm somewhat confused about the exact use of BH and BS, but Vcc appears to be required to enable the battery to turn on entirely.
If anyone have done a rebuild on a Worx 20v tool let me know what you've found on this topic. Also just wanted to check if the C1-C4 pins are in order from bottom to top of the battery pack like you'd think, or if Worx did something different.
