I have a quality charger, I took the batteries out of the package and tested the voltage of each cell through the balancing lead.

Charged the batteries to 4.2xx each cell on the 11.1 and 7.4 and put them into the respective guns. Ran the batteries, at the end of the day i check the voltage on the batteries and ensure they are above 3.3v. I had a lipo cutoff on a alpha version of the Trigger master v3.9, it cuts off at approximately 3.3v each cell. At the end of the day if the batteries voltage range was 3.3v - 3.8v / cell I put them away and will charge them before the next game. The one 7.4 battery didn't live beyond it's first charge cycle and use on a stock TM gearbox (v6). The 11.1 lasted perhaps a month or about 5-6 charge cycles in my M4.

Once you move away from those awful buffer lipo to a nice brick style you never go back. 12-15c providing a continuous amperage of ~25-30 is really anemic.

I've had several LIPOs go puffy after RC use on helicopters / planes but that took several 6-8 months of using the battery hard.
