cutoff voltage can play a roll in the need to balance as well. Depending on the quality of your backs and how low you set the cutoff, the cells can get out of balance more so than with a higher cutoff value from what I have seen, especially in 1/8.
Me personally, I run a duo style charger so the extra time to balance-charge a pack is insignificant.
so, back on topic, anyone have a shock and piston suggestion (AE) to start with for indoor carpet? Picked up some AE shock springs and pistons, big bores to go in some kyosho shocks to make comparisons easier to everyone else. Last jam session front felt great, rear needed a bit resistance coming off the big jump on to the concrete-ish surface.
