So yeah i have homemade batteries on all my cordless tools. Each battery pack (5S) has a balancer BMS module and a big MOSFET that opens when the battery goes below 18v. All of the tools (rated at 18v) are standard DC brushed motors with pwm control, which i think implies that they must have a freewheel diode so therefore i don't need to add one.... i guess.
does anyone have experience with this?
