    Rigid Battery Adapter

    Posted by John deWit on Oct 24th 2021

    Great product for converting older cordless tools to LI battery use. I’ve ordered 3 of these and on one of them the battery is difficult to slide on and off.

    Very impressed

    I was very impressed with the build quality of this part. It fit my Ridgid batteries perfectly, even click-locking into place so it doesn't slide off. Quality, heavy-gauge wires made connecting it into my project easy. Also appreciate the mounting holes as I may end up mounting it in the future. Great purchase.

    I'm using the adapter to convert 18vdc to 12vdc via a step down buck converter. The uses are several; any 12 vdc device...I have photos of the finished converter if that would be of any interest to you for future sales and applications.

    The quality of the the print is really nice and clean. It's actually a perfect fit. I was skeptical at first because my printer kept warping the model, but this is perfect.
