I picked up a vmax the other day and was wondering if i had to get special batteries for it or if the ones that came with my vamo were just too fat. both sets are 18350, the ones i got with the vmax i think are 600mAh while the ones in my vamo are 800. i already had some 18650's from a flash light that was stolen that fit the vamo. i just cant get the better bats in my vmax, and i dont want to break it.
