This is not a helpful comment. There is danger. Criticizing someone for caring about somebody's well-being is short sighted. There are some people that need to be warned. You may not be one, Karen.Thank you safety police, you saved my life. Do you have any other confused tips? Perhaps how to drive a car?
You can find used 26650 A123, and a Chinese factory that knocks them off, now that A123 is no more. 50 cents each. 2.5 ah 3.2 v. Charger for said lipo is $10. Fits in C cell lights, with a spring stretch. 2cell lights can be replaced by one cell. 3 cell lights 2 cells for 6.4v. In D cell lights one for one with spring reduction. Double your voltage. Can't nick these cells. I ruined one by shorting the case with a sharp spring.Recently ended up with several lights using 18650 and 21700. Want some extra cells. I know everything at places like Amazon/ebay is fake, and do not hold the labeled capacity.
Edit: see below - branding and badging covered.
I tried to buy "Samsung" 5ah 21700s from IMR Batteries and they could not be more fake. 4.5ah. No branding. The fake capacity is just a sticker out of a label printer. Samsung had nothing to do with these...
Who can I actually trust to buy these batteries from? Is it even possible to get a real 3.5ah 18650 or 5ah 21700?
ThanksPlease stay on topic. The topic is single 18650 and 21700 batteries, nothing else.
I need to get out my WMR-Battery Analyzer.
