More powerful batteries

Has anyone else tried the "new" higher voltage batteries? they're called "powergenix" and they're 1.6 volts instead of the standard 1.5 and they're rechargeable. they really make your battery device "take off" ha ha. with dc current the higher the voltage the faster the device runs.

And the quicker it will burn out!!! x

Get one of those ones that plug into a wall
