I do not have the voltages at start. Keep in mind I'm new at this. The battery does disconnect when the voltage gets too low. I wish I had correctly tested it. It may have been zero or not.
Ok. Another post of yours said "I don't have voltage before charging." when I asked you specifically what the cell voltages were, which one interpretation of which implies that the cell voltages were zero, because a previous post said " I'll check the voltage before giving up." which implies somewhere between there you did check them, without a statement that says otherwise.
Another more loose interpretation could be that you did not measure the voltages before charging, but that is not what it sounds like. (but from what you say above, it is probably what you meant).
It's very important to be very clear with specific answers to specific questions when troubleshooting, because the results depend on that. We can only know what you tell us, and what we can deduce or imply from what you tell us. So what we tell you is based on that, and as the saying goes, "garbage in, garbage out"--if you tell us wrong information, you get wrong answers back.
If you have no idea what the cells were before charging, then they could all have been perfectly fine, and there may be nothing wrong with the pack at all, other than it was not charged sufficiently on the cells the "charging relay" runs off of. (whatever this "relay" actually is, and whichever cells those actually are). It may have a long and healthy life ahead of it....
Since you don't know, it *is* still safer to treat it as a fire risk, as you are presently doing.
