8 Pack 18650 Rechargeable Battery 3.7V 5000mAh Button top Li-ion Batteries for Flashlights, Headlamps

They are perfect

I have a smart charger when I charge these batteries they are identified as NIMH/NICd. Not li-ion like they claim. The charger recognizes and charges three styles of batteries and these also do not have BMS cause 2 have crapped out and won't charge already. Very disappointed with this purchase and feeling scammed! Picture proves both claims with a real li-ion battery also charging next to these scam batteries!

Great battery’s and bang for your buck. Had no problems charging or anything would definitely buy more

I've run 4 of these through a gauntlet of 3 battery testers.Capacity(4 batteries averaged): 1121-1205 mah @ 4.2->2.7v drop @ 4watts 1182-1219 mah @ 4.2->2.7v drop @ 20watts overall average ~4800mwhpower(single battery used for all tests): 40amp at 4.0v 3 second load successful (voltage remained above 3.0v, battery didn't explode, but did get very hot compared to other brands, no built in SCP) 12amp at 4.0v 3minute drain test battery above 50c, end battery voltage after cooldown 3.5v 20amp at 4.0v 3minute drain test battery above 70c, end battery voltage after cooldown 3.1v 22amp at 4.0v 3 minute drain test ended early due to battery over 80c.for the price, it's not a bad battery if you don't need much and have 18650 hardware, but they're the smallest capacity I've seen outside the kind that come with a built in usb charger.only slightly more trustworthy than the other asian options.

So far so good.They measure out to 1200mah.Not sure how long they will last... Time will tell.

Don’t waste your money with this trash
