Bosch battery adapter for Bosch Power4All battery

thingiverse

I had some a spare power4all battery lying around, and wanted to use it to power my old Bosch tools. The battery is 18V, and the drill only 14.4V, but it works fine for me. For me it was a cheap way to get some use out of my old tools. Use on your own risk. To hold the Battery I used another design, but since that was not holding the battery well in place I reworked it slightly. And I added some build in supports, that were easy to remove with a small screwdriver and a knife. https://www.thingiverse.com/thing:3318613 To assemble, you need some screws, spring, wire and a copper strip. It also fits the older style batteries, but when using these you need to be careful to not discharge them too much. Because these older batteries don't have the protection build in. And when you discharge them too much, you kill the batteries.
