How old/new are your batteries?
Are they getting warm when you charge them?
How many amps do you charge at?
all the above will/can affect punch
I used some old 3700's from a few years back when I run my sidecar with kit M'troniks esc an it's as quick on the straights as some 4 cell cars. Just can't get the power down though to keep up but I can see the speed in the chassis.
