An emaxx on 4s needs a batt capable of at least 125amps cont, I would go for something with 150amps cont myself. 4s is hard on lipos, you really need 5000 30c lipos, or 6000 25c. A pair of 3000-3500 30c 4s packs wired in parallel would be my choice for the emaxx, as I do not like packs made with internally paralleled cells, such as the larger mah maxamps packs. Some enerland 3200 30c 4s packs would be a good combo. Or maybe a pair of zippy 4000-5000 20-25c 4s packs wired in parallel. Not as light as the 30c packs, but much cheaper. Still close to 200 bucks worth of lipos.

The previous info was given assuming that you will gear for 40-45mph. Higher gearing will require better lipos if you plan to continue with 4s. If you want speed go to 6s and get a pair of 4500 30c 3s lipos, or go all out with 6000 25c 3s lipos...
