Increase voltage in my 12v Ryobi drill? Answered
I have a Ryobi 12 v power drill that is really tired. I don't wanna buy a new battery because
after a few month it got so weak. I read the inspiring post
Hot Rodding a Power Drill Battery by archer6817
and would love to try it. But I have a question.
Can I increase the voltage if I put in new cells,
like 14 or 18 volt?
