Awesome. Thanks guys for responding. Think I'll try the safe options! I'll probably end up buying some LiPo's anyway, just wanted to salvage what were at one time some very nice matched packs. I know they're no longer race worthy, but I'm sure I can still get some use out of them.
One more question, after connecting all four packs to my charger, three of them false peaked as I described in the original post. The fourth pack wasn't even detected by the charger. It was like it wasn't connected. I tried connecting through the Deans plug and also used alligator clips to circumvent the plug, but no luck. Is it possible that a cell in that pack has completely lost its ability to even pass current? I'm almost certain that all the connections are solid throughout the pack, so I don't think it's as simple as a loose battery bar or something like that.
