Keystone 209. 1 Cell Leaf Spring Battery Contact, Spring Steel, Nickel Plating (Pack of 20)

Fantastic clip. Ease of use with 3D Printed models (Just search for, "Ryobi" on any 3D model site) to allow you to build your own applications for Ryobi's batteries. A good model + These clips results in an extremely professional result that is very useful. They fit extremely well and secure on reasonable wall thicknesses (~1.0mm) and are perfectly sized to the Ryobi battery. Very secure and stable connection. Vibration immune. Throw a bit of glue for even more confidence (but not really needed).

works great, I didn't use them for the intended purpose. used them to connect 2-20v battery adapters to a 40v skil lawn mower

I used these to turn Ryobi tool batteries into portable benchtop power supplies. I got the voltage regulator off of aliexpress for $1, and used these battery terminals along with a 3d printed handle designed for them. You can find the model as "Ryobi Power Deck (Battery Adapter, Power Supply)" on Thingiverse, thing:3498860. These terminals are a perfect fit, high quality, and easy to solder and work with.

I add these to my 3D prints to make functional converters for Ryobi battery packs. I thought they were a little expensive, but after using them I feel they are well worth the price

If you are making a DIY power supply using ryobi 18v batteries, these have the best contact.

I had to remove the small wire loop at the back of the clip as my 3d print didn't have room for it. Wire solders to the clip nicely. Used this for my FT2DR 3d printed replacement battery pack. Thingiverse thing #4804346.

Doing a DIY battery project, and it's 50/50 if solder will stick.

These battery clips were a perfect fit for my vintage Simpson 260 meter. The clip tinned very easily and slid into the battery holder perfectly after soldering on the wires from the meter.
