Makita CXT(2) to Ryobi adapter

I have a set of Makita CXT drill / drivers and started building this before I bought a LXT battery. I finished it because I wanted to see if it would work. This will work fine on old brushed tools, I would not try it on a new brushless tool. USE AT YOUR OUN RISK.

The original design has amazing instructions, and works really well with my LXT batteries. 

The design uses M3x 15 self tapping screws.

I used 8x100mm nickel strips folded in half and cut down for the battery terminals.

connected in series as seen in a picture.
