I have come to the conclusion to rebuild my battery packs.
My Ryobi 14.4v drill batteries are giving up the ghost.
The plan is to rebuild them with 18650 lithium cells if i can find some cheap..if not more Ni-cads.
If i end up going with Ni-cads again I'll install another 4 volts for a total of 18v, giving the drill a nice boost.
Right now the battery charger charges the 14.4v batteries to 17 volts.
