A way to get around that, is to set the charger, to charge a Ni-Cad or Ni-MH. Charge it for 5 minutes, then switch to Lipo charge.

I have heard of people doing this and it worked! Just keep an eye on everything!

Yes, as stated it can be done, depending how low it went.

A charger that displays voltage per cell is your best option.

Start at 1A and monitor voltage per cell to assure they are charging within .05V difference. This is a "base" indication of how good they are or not.

*IF you have a cell charging faster than the rest, its the bad one. Also applies when discharging.

Stop charging when voltage reaches 3.2V per cell then switch charger to lipo mode and try again.

After a full charge, I would cycle it once (discharge - charge) to find out total capacity vs label.

My radio shuts off at 8.6V...yours?

Your TX battery is LiPo.
When you discharge a LiPo to 0v (or close to 0v) - it is destroyed.
Buy a new battery.

It depends on what voltage per cell the batteries are sitting at right now... if they are in fact at 0.00V then yes, but if his charger shuts off at 8.4V then they might be salvageable.
