I was thinking of making a pack of GP2200's up for my TC3..9 cells for the weight of 6-7.

OK realistically 4 packs of 5s lipo is outside my budget. But a bulk order of 40 GP2200 cells isn't much more than a single 5s lipo of a good capacity. 40 cells -> 4 packs of 10, two packs/cycle so 20 cells a run. Thats starting to sound realistic. Would it be safe to push the 9920 to 20 cells every run? I'd run a fan over it to be sure but I dont' want to risk damaging it.

What sort of runtimes do you think 20 GP2200 cells would give compared to 14 cell GP3300? Math tells me 20 GP2200 cells is about 900-950w of energy output, more for peaks. Surely thats enough to break 50mph with semi decent runtime? Thanks for the advice, I never thought of using smaller cells but simply more of them.
