From what I have seen the true rc cells are not exactly the same as maxamps cells, how ever the performance seems to be about the same. I have had a bunch of maxamps lipos, and returned about 75% of them for replacement. It seems like members here have had great success with true rc packs, I am sure a pair of the 15c 4000mah lipos would work fine with a stock emaxx. You would need to run a seperate lvc, like a li-saver or novak smart stop module. The evx2 does not have a lvc built in.
