Description:
Holds up to 12 AA batteries in a compact tabletop hopper. The batteries go in the top and are directed to the bottom of the hopper by 3 ramps. I want to make the next version automatically charge the two batteries at the bottom of the ramp and would love input and thoughts on this idea.
