dumb question..but can you buy an aftermarket 20v LION that will work with an 18v NICAD dewalt drill?
i mean..is the juice a function of the battery or electronics in the drill itself?

Pretty sure the pack is going to supply the voltage it's capable of, and I don't think the drill will like a voltage it's not designed for.
I'm not an electrician or ee or anything, but I believe supplying too LOW a voltage can result in a device drawing more amps than it's designed for in order to reach the desired wattage. This can result in overheating and failure.
If you supply too HIGH a voltage, I think this can push too many amps, also resulting in overheating and failure.
Or, more likely, the drill checks the voltage and will refuse to work. I think.
Anybody smarter than me around to correct me?

quote:do not use Lithium in a drill not designed for it. They have circuitry built in to shut off before the battery discharges too much.That is what kills lithium,discharging too much.
