Using A Power Tool Battery As A Range Extender


Well-Known Member
If they're asking $250 for a 15 cell battery, they got plenty of margin for protection circuitry. You have to watch every cell to make sure it doesn't go past the minimum., or it's at risk of being damaged.

All I see is 2 or 4 pins going to the tool on these batteries. There's an internal BMS in there. Otherwise you need an extra 16 wires to monitor the cell voltages.

Thanks for posting. I use Ridgid power tools and now I might have a little project for my eScooter.
Hell me too! So when I blow up my ridgid 18v batteries I can have them replaced according to their 3 year warranty! T-20 torx anti-tampering bits here I come. HAHA.
