This probably isn't a new idea to most, but for me it was a breakthrough! I got sick of man handling my YR1030 with the cord dangling and test fixture getting wacked and misaligned. Mounting them solved that problem and frees up a hand to speed up the work. I can hook it on the edge of my bench or jam it up against something and remove/install cells with one hand. Hallelujah! Super easy now to move around and store also
