18v Black & Decker to Bosch Battery Adapter

I have 3 Black and Decker power garden tools with ni-cad batteries that are near the end of there life. Luckily I have 3 18v Bosch lithium batteries but needed to make an adapter to suit. My local hardware store has a 3D printer and one of the guys there found a design for an adaptor online which he printed for me. They also gave me an old 14.4v charger they had that had been returned under warranty which I used for the plate/blade battery terminals.. Now just to cut up an old battery!

Finished off with a little black silicone and a polycarbonate piece that also holds down the negative contact and the b&d electrical terminals..  Runs really well and cost next to nothing!

The weight balance has not been effected by the extra height.. Just needs to be sealed off now

I cut down the old battery case with a multitool and used the original screw posts to secure the adapter.. I know it looks a bit bulky but this allowed my to retain the spring clip at the front while retaking strength in the case

I used a 14.4v lithium charger and removed the individual plates leaving some board to help with stability.. I used sheet metal snips then flatten and filed the plates giving a decent leading edge
