torq - I wouldn't expect leads a few inches longer to be the prob. It would have been helpful to know what another charger would do as far as charging them or not. I'm not familar with your charger, but the Reedy lipos are supposed to be real good ones and that plenty of voltage. Check charger and make sure teh minimum lipo voltage is not set too high - it should be ~3volts/cell.

I'd still be suspicious of the soldering. If another charger charges you lipo, then its the charger.
