Fantastic help Duckster, Thank You 😃 From the Amazon Link you so graciously provided me, this doesn't look like something that would interest me although the size and price certainly fit the bill. Why I don't think it would work is that you either have to remove the battery pack to charge it or open the device its in to do a recharge. Although just sitting here writing this reply maybe the plug end of the battery unit can be affixed to the item being powered and the charger plugged in without removing or opening the item. Or.....if the building or whatever is housing a motor is big enough to have an access area to be easy to open and get to and simply swap out a used battery for one already charged. Hmmmm
EDIT
Did just noticed that the Mini Motor Gear Box in the video is 3 volts and the battery pack is 3.7 volts and its wired without resistors...hmmm, would that blow any 3 volt LED's connected to the same motor...I wonder
