lipo batteries

hey every i just picked up a Sidewinder ESC & CMS5700 combo for 60 bucks and a 49 min drive im putting in my xx4 i was wondering what would be a good size lipo batt.
i plan on racing this truck at my local track (oc/rc).

does anyone use this charger?? looks like a good charger and great price
and charges 6 cell for a brushless mammoth im working on =]

Good charger, cheap alternative to things like the BC6 and 606i.

With the sidewinder and cms5700kv motor, I would keep it on 2s lipo for best results- probably something like a ~3000-4000mah 25-30c for best runtimes and cool temps. Basing that on the xx4 being like a belt driven 4x4 slash, sort of..

would this fit int my car??

No idea- time to break out your tape measure!

You will want/need to add a little to the lipo measurements as they arent 100% accurate- you dont want to have an uber tight fit, so allow for about 2-5mm.

wishful thinking perhaps

I said 2-5mm, not 2-5"... 8===D

Off topic in only 5 posts- that has to be a new record.

i think i might jump ship and convert my rc10gt to BL
