I had 2 2s 8000 true rc lipos for a brushless e-maxx. The guy I sold it to still uses them and hasnt bought another battery b/c it lasts so long. It doesnt have the punch or power of the enerland 6000 25c lipos that I have but were more punchy than the elite 4800 25c and the protech 4000 20c lipos. The elites will take a little more punishment though
