What do you guys think i should run, 4s2p 8000mah pack , or 5s1p 4000mah pack... I will be using a 1950 7T Hi-amp motor. Probably 125B or 9920..

@ Serum ; i know you havent post in this thread , but was wondering, since you've already done 2 of these types of conversions.. Should i try moving the center diff to the center of chassis or keep it off set like it already is, and than put the pack on the opposite side? I was thinking of putting motor on the side with a lay down motor mount. P.S : would you know if the new 10K mah maxamps cells would fit in the lsp? thanks.
