Well I got one pack with a dead cell, one pack that dead shorted so I need batteries and I don't wanna by batteries to run for another month. The batteries I would buy now would be junk come next season so I would be ahead of the curve to just make the leap to a single cell lipo and start messing with it now. I talked to my local track owner and he says running a single cell and a 13.5 is going to be fine for stock racing. So I'm just wanting to know rec. pack or voltage booster? Anyone making a weight tray for the single cell yet?
