Ryobi Battery power supply

thingiverse

I needed a variable power supply for a voltage regulator and for a robot I'm working on. I thought about ordering several lithium Ion battery packs and wiring them up when I realized I had half a dozen packs for my tools why not utilize them. hence this cap. I used keystone 204 battery clips and soldered a fused connector to each. they slide right on the print and it pops right on the battery. I did notice with some of the stiffer clips (depends on supplier) it helps to scale to 102% or 103% it will still be snug because of how tight the battery clips are. Here's a link to the 20 pack I got I'm sure there are several dozen places to get them, or just rip them out of some broken remote the should all work about the same. If your contacts are larger I'm happy to modify. https://www.amazon.com/gp/product/B00XYSUURS/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
