In this video, I do a capacity test on a 21700 5000mAh Li-ion battery from TinkerTechAU. I got a pair of these at a great price of $7.99 each. The battery is intended to replace the more expensive Samsung 50E while providing the same capacity of 5000mAh and slightly more powerful at 15A continuous discharge rate at lower price.
