Review on ⚡ Circuit 90 150A Battery Storage Lithium: Unleashing High-Performance Energy Retention by Jathan Louis

I bought this one thinking if it didn't work I wouldn't lose much because it was a cheap price. I was wrong! This little spot welder worked great right out of the box. You can change the power level by pressing the small button on the circuit board. Repeatedly pressing until the indicator turns red sets the maximum power. Other settings are lower power which may not work on thicker tabs. I used it to build two battery packs with good welds on both packs.
