yeah i saw those 2, i was thinking the same thing, im looking for some battery holders like the one that holds 2 aaa but i want 2 that hold 1 aaa and im gonna try and figure out a different way to mount them. ive discovered that with the pack were it is currentlty the car is really top heavy so if i make a really sharp turn it almost wants to roll. but i bought the supsension kit so this should help that.
