Cool but doesn't work 🤣
I think the tool needs more signal -
I thought it is chinese BMS not capable and bypassed it by adding original dewalt PCB.
The original PCB also has NTC sensor on it.
I measured the voltages all fine. 20.60V at the drill.
Again, LED goes on/off but the motor is not turning.
What does the tool wants to know? Or whats could be the problem?

Hiya!
I'm trying to built my battery pack.
I had used LG HG2 3000 mah batteries which has 30A peak discharge.
The problem is DCF880 drill doesn't want to turn. When the switch triggered LED goes on/off but the motor is not turning.
DCF880 is fine because it works with the original battery.

Okay just found it. The tool needs C1 & C3 as an input.
C1=4.2V
C3=12.6V
Now I'm modeling and printing the case for it. It would be uploaded to thingiverse.com for the ones looking to make their batteries.
