Yeah, with 6.6, you could store it right after LVC on your speedo -- I think they cut off around 3.25 or so a cell. Doesn't sound good to me either.

Depends on how far you drained them. Lipos have self discharge, it's just very very slow. The purpose of the storage charge is to prevent the battery from going below 3 volts per cell and being damaged. If your battery hits the LVC on your last run, you probably want to put some in there just to be sure, but a full storage charge isn't needed. leaving too much charge increases the lipo's self discharge rate, which is why the recommended storage charge is around 3.8 per cell.

When I race, I just leave the pack where it was after the main till next week unless I break or don't get to run, in which case I discharge it to at least the storage charge level to ward off high self discharge rates over time.
