Ryobi battery adapter

thingiverse

I built an "adapter" for a single-cell battery for Ryobi tools ONE+. Last week I bought and used (5 years battery) with 1.5Ah cells. Since I had a set of 5S2P welded battery packs (5Ah) for electric tools, I decided to add a spacer between the cover and bottom part. It works very well using the original electronic BMS board with a 4-bar indicator. I replaced the original "star" screw with a classic PZ1 M3x35 wood screw. All build steps are in the "how I designed this." If necessary, I can take additional photos/videos of the battery content. This is not a 100% proper model. The project is for someone who has DIY skills - a little grinding, cutting, gluing, and basic tool operation! There's a risk of battery damage, fire, and electric shock. Be careful!
