Summary

I simple battery adapter for a JCB 20V battery. It uses three screws (I have no idea what size) to attach the top to the bottom, and uses spade connectors to contact the battery terminals to wires. The batteries also have a little blip by the terminals, I just snipped it off for simplicity.

This model was originally and for a 20V battery Dewalt battery. I can't remember where I found the files for the original.

Let me know how well it works for you. Might need to slightly modify files for better fitment.
