Want most powerful setup for Revo

[Gustav]

Was it the little brass pins that key to the steel slipper plates?

For Lipos check out FMAdirect cellpro system(the 3200 20C packs),it's very userfriendly if you've not had lipos before,monitors each cell on charge and discharge,has it's own dedicated charger so it's as foolproof as possible.
I'm using flightpower/duralite evo 20c packs with a schulze 330D charger,polyquest 'twenty' seem to be the same cells.
Lots of good lipos around,go for ones with a high discharge rating and with balance taps installed.
