RYOBI 18V Battery Adapter Cable

I wanted to be able to plug one or more external batteries into RYOBI tools. I designed this adapter to fit in where the battery normally attaches. For example, with a RYOBI Inverter, you can connect a bank of 18V batteries and have a longer run time.

Here's a youtube video that explains the reverse engineering, 3D scanning, CAD design, and assembly:
