This Forum has helped me tremendously in gaining knowledge about cells, cell testing and BMS’s. This site also steered me to the Facebook DIY Powerwall group. Today I graduate from 18650 to 26650 as I have met my new best friend who can supply me used parking meter packs for free, well almost free. I have to break down and test cells for him. So for how ever many I take, half is his. I took 280 cells today. His testing has yielded no bad cells, his lowest capacity cell is 28xx mAh. This time I will build a 16S100P the conventional way with spot welded nickel strips and a BMS. Any body seen this before? An Opus tester testing 26650’s on banks 1 and 4, banks 2 and 3 had wires solder to them leading to 26650 cell holders. My new friend is a genius. But my question is any real 26650 testers out there?
