I rebuilt my cordless drill battery pack and I'll take my lumps for
being a moron, but I reversed the polarity of the cells, so the leads
are reversed. My drill has a forward and reverse, so will this pack
still work, just in opposite direction from normal? Secondly, do you
think it will still charge normally or should I not even try and risk
an explosion or death to my charger?

the pack apart, and swap the 2 leads - simple enough and alot cheaper
then a new charger, batteries and drill. You don`t charge your car
battery the wrong way, you don`t reverse charge Nicads either. It
likely might work in the drill - awhile, but frying the speed control
is most likely. I hope you properly Heat Sinked the cells so you did
not overheat them while soldering, it is another way to ruin them
fast. At least you caught it and asked, you will be ok, you are not a
moron, you found a simple mistake.
Thanks, problem was that leads are molded into plastic clip, so I had
to run a new wire to swap the + end of the battery chain with the -
end of the battery chain and connect these to the lead wires/tabs. i
did get the batteries with tabs already spot welded, so i don't think
i overheated. thanks for the advice....fixing the problem was easier
than i thought...i was thinking I'd have to unsolder the entire chain
and redo, but with extra portion of solder tabs already trimmed, that
wouldn't have worked. now to charge up and see what happens...
