RE: LiPo charging between heats?
Yes you can do this. As far as how long it would take to do it, well that depends how much you take out of the pack. We have many racers using our 6000 packs and a lot will run the qualifiers on one pack without topping off. They then run a second pack for the main. I have even had some guys go as far as 3 qualifiers and a main on a 6000.
