New project batts may decide..

[miniGranis]

Well my 8ight deal fell through :-( But I sold my E-Maxx today :-)
So off we are for a new project:
Looking in the closet and a rough esitimation of funds and I came to the conclution that I probably have to re-use my lipos so here it goes.

I got 2x 3S 6000mAh Lipos (Maxamps) and I sometimes use them in my Crt.5 (a bit on the hevy side).
I want either a buggy if possible but if that is out of scope a truggy could also be fun.
So the basic question is: Is there a buggy (or Truggy) that can (easily) be converted and run two 3S Lipos on seperate sides of the chassis with ok performace ?
I will probably use a 6S config, since 12 Ah is hardly usefull.
So any ideas ?
