If your using 12 cells on each esc now, I'd use 2 4s packs of the same age and specs. If you use 1 4s pack on each side you won't be able to sit some of the batteries under the chassis like you do now obviously, but I wouldn't want to do that with lipo anyway.
Your chassis looks like it will hold more than 6 nimh cells length ways, so if you have about 165-170mm of space I'd look for the longer style lipos since they sit a bit lower than a normal length pack of similar capacity. I'd probably go for the 5000mah 25c enerland cells (flightpower, poyquest and a few other brands that I forgot), but you should be able to loose some capacity if you want, since 5000mah 25c packs can do 125 amps, and you'll be using 2 in parallel...good luck trying to put 250 amps at 4s to the ground
Thank you for that info, I was wondering about that.
When I built my twin motor nitro I was told that each motor needs to be perfectly in sync with each other...... that was absolute BS!! I could run one motor fat and one motor lean, it didn't matter they both temped the same. How ever when they were both tuned perfectly the truck would take off like a rocket :)


Sweet as hell truck plentenbergs!!
