Leaving a charge on lipos?

[MetalMan]

It's best to keep Lipos stored at half capacity, around 3.80v. Storing them fully charged can cause them to lose some capacity, thus shortening their overall life. You can discharge Lipos on devices used to discharge NiMh, and monitor the voltage of the pack with a voltmeter. Disconnect the discharger when the pack gets to 3.7v/cell. It will rebound its voltage a bit, and it should be fine stored at that level.

I store mine for a week or 2 at a time charged. I havent seen any bad effects. Although I try not to leave them sit at full charge longer than that. I just toss em on the discharger at 5 amps for a half hour just to take the top off of em and then put em away again. Although, they rarely go unused for that long.:018:
