Ok so I bought these after getting a honest review from a YouTube chanel that did real world tests on them. For their price and application as a rechargeable 18650 for headlamps and flashlights they do a decent job. Though don't believe for one second they are 5800mah, real world 1000-1100mah low drain rate unprotected 18650's are what you really get. My skywolfeye headlamp still runs for hrs on them and are good for my uses. Charger works well but as the Youtube review states it charges these to 4.25V so its right at the very edge of the 18650 chemistry maximum technical voltage limits. Eventually i will upgrade to a smart charger to prolong battery life span. Cheap and it works so it is what it is, flashlights these work well for the money.

The chargers work well so far but my issue is the batteries. They have a claimed 5800MAH capacity they don't have that at all. If you want a cheap set of batteries and chargers this is the way to go though

These batteries are of great value and charge quickly. The flashlights are energy hounds so they use up the energy really quick and cause a lot of heat due to their inefficiency. The batteries are great and they give what the lamps need, however, they are a specially sized battery that is customized for these type of devices and it is best for a kit like this with a charger to ensure they provide a long term functionality , as li-ion batteries do. A great plus is that cold weather doesn't discharge or kill them!

These batteries are just awesome. I ran 3 batteries {3.7v ea} in series to make apr 12v. In this case, fully charged they are about 4v and can take alot of abuse. I run them in my Nerf gun which draws some pretty good current. They hold really good charge and last a long time between charges, Thanks for the GREAT Product and EXCELLENT deals

I will argue that the brightness of the flashlight is what you claim.......I have already seen two other's that are brighter and shoot at a longer distance.
