11.1 Volt Lipo Question

[kikcaffine]

So my helicopter (I know this is a car forum but I figure someone could know about lipo here) has a 11.1 volt lipo pack. Its not taking a charge anymore, the charger says error. Its the stock E-Flite one. The voltage says its 7.40-7.45 volts on the little red connector. Can I charge it still? Or can I give it a voltage kick with a regular charger to get back to 11 volts? What should I do with this?

If you are REALLY CAREFUL (read EXTREMELY CAREFUL), sometimes you can charge them on a NiCd/NiMH setting at literally .1A (or lower if possible) until the voltage gets above 9.0v.
You have overdischarged your battery by the way. The absolute minimum that battery should ever be is 9.0v. Make sure, when the heli doesn't want to climb very well, turn it off and charge it. LiPos also don't like to be stored "dead" ("Dead" meaning around 9.0v)
Watch the pack the entire time it's charging. If you notice any heat build up or swelling, dispose of it properly (salt water/trash)

I can charge them at .5 amps. How long for though?
