[E-Revonut]

Generally using 2 2s, or 2 3s packs is for balancing a truck out or in the case of the E-REVO or E-MAXX thats what it was designed for. It balances the truck out side to side. The reason for higher voltages is to reduce current (Amp) draw to get the same power output (Watts) Watts = Voltage x Amps If you increase the Voltage the Amps needed are less, therefor things will run cooler as current produces heat. As far as using 6s in a buggy, IMO I think we don't see this because of a lack of room on a buggy chassis for 2 packs and there is only so much room under the body to fit a pack. 5s has been run on them though. IMO buggies are much lighter and have A LOT less rotating mass than a truggy or MT and can easily survive on 4s
