There is a blurb at batteryuniversity that says keeping lipos at elevated voltages promotes cell corrosion on one of the plates. It was actually for Li-Ion, but the technology is similar. If I'm not running them for a week or more, I keep them at around 3.8v/cell, which is between 1/2 and 3/4 charge. I figure at worst, I have to charge them a little while the night before to top them off.

But having them puff after on;y a night or two at full charge? I'm gonna call shennigans on that one. Chances are, they were just overdischarged despite whatever their labels say.
