Well when I ordered the light, it came with 2 18650 batteries separate in a package. When I opened the battery package, one immediately had thermal run away in my house and almost burned my dog down. Thank god it was not on my head. Then there is the issue where most 18650 batts wont turn the thing on. I have to take out and reinsert and screw cap super tight for there to be a connection. It could work fresh off the charger, throw it in my pocket,
Head to hunt, then it not turn on and its games time. It could work in morning, then at dark coming down/getting back to truck, it wont work again but batteries are good. Basically an unreliable POS based off of my personal experience.
