Dewalt 18V Battery to Dewalt 12V (NiMH) Skin
** you will be over volting your tool **

Extra requirements

2 x 6mm male spade connectors
2 x 6mm long male spade connectors 

4 x M3 nuts
4 x M3 10mm socket head bolts
2 x wires
40mm long, 5mm diameter, 0.5 gauge spring, clicky pen spring might work too

Prep spade connectors like this, flatten out the shoulders if you can

Prep long spade terminals like this, it's folded to give it some thickness.

Assembly Guide

I find if I run a 3mm drill bit through all the bolt holes, it helps with getting the bolts in smoothly.

Remove the insulation from the spade terminals and install one on one end of each wire and feed it through the holes in the base plate, matching the polarity. Use some pliers to push the terminals in for the last few millimeters, they should fit nice and snug.

Load the nuts into the base plate.

Load the spring and buttons into the base plate, then feed the wires into their respective holes inside to the top of the male Dewalt post section, then screw down the top plate to the base plate whilst ensuring the wires are pulled through to minimise slack inside the adaptor.

Cut the excess wire exiting the top and install the folded long terminals.
