Sadly he is going out of business. 90+% out there is junk, have 26650s with 1800 mA. Last week finally located a reliable vendor, purchased seven 21700 Samsung B50s, reasonable price. 21700 is a better fit in the 50 X 65 X175 mm battery frame. After extensive dialog with vapah.inc and bench tests of all seven 4800 to 5200 mA, I am convinced that I found in the US a very viable source. No commercial or any other interest, now my only problem is how to get rid of the other junk.

I use their LiFePO4 batteries to build packs for lots of different kit.
