Ever want to use a Roomba Battery in your own robot? Here is a way to build a remote charger.

Step 1: Bottom Plate Surgery

First thing is to get a bottom plate. Then cut the battery box off. I did this with my hack saw and then cleaned it up with my Dremel. Make sure that you keep the battery connectors and connector cover with screws.

Step 2: Now We Need to Put the Stuff in a Box.

This a Sterilite pencil box you can get them for $1.00 each.

I mounted the battery tray under the cover. So you need a template and steady hands. I used my Dremel for the cut outs yes you will need one for the battery connector block, as well.
