Gearing an ERBE for racing on 4s

[shaunjohnson]

with a little thinking you can charge the 2 packs at the same time...
the charger will see them as a 6s pack.

you will need to make an adapter for the balance lead, so cells 1, 2 and 3 are immediately followed by the other pack's 1, 2 and 3 cells, then rig up a common ground, connect the packs in series with deans adapters etc and you have a saddle pack.

here's the catch those 2 packs MUST ALWAYS be used together no matter what! you wont be able to put one in your rustler and run that, they are always connected as a 6s pack.
