For the price, I do not know, it’s an Australian contact who sold me for about 3usd / piece and I had more expensive shipping than batteries, but the curiosity has taken over the reasonablity at the time (lol), I do not know how much he had paid or even how he got them, I searched everywhere on the net and I found no place where he sells this model, even if they are better than the “liter 20650”, it is not worth the quality / performance of Sanyo or LG, moreover it’s been more than a year that LG 20650 “HH2” is expected but still nothing available today, they are supposed to give 3500mAh typical capacity and 20 amps continuous. As well as an LG 20650 “M42” giving 4200mAh typical capacity and 15 continuous amps, and still nothing available. After I heard several rumors that are substantially all the same: like what the 20650 is a format that would sell rather badly. It’s sad because I think it’s a good alternative to the 26650 format.
