Thanks for this interesting disassembly video! I bought two flashlights just like this one over a year ago, and they turned out to be just simple flooders although the ads deceptively sold them as throwers. 🔦😐 They were cheap and I knew these were meant to be disposable. I had expected to see a generic 18650 inside this light and found it interesting that the manufacturer went even cheaper by using a lower capacity, 14500 lithium ion. I'm not surprised if these batteries are substandard or even recycled ones that were bought in bulk. It probably cost the factory a few cents per cell. In my experience with this kind of flashlights, they usually fail prematurely on account of their batteries, long before their driver electronics or LEDs reach the end of their lives. The downside of disposable flashlights is that they contribute to e-waste and I'm sure many of them have to be replaced because their cheap batteries went bad, much earlier than the flashlights' potential lifespan. The only reason people would buy something like this is because they are so cheap that it wouldn't hurt so much if they were borrowed and not returned, lost or stolen. 😀 Working with lithium ion batteries carry a certain amount of risk to the uninitiated. I think one of the reasons the manufacturer makes flashlights like this one a sealed unit (that also goes for USB rechargeable personal fans) is that they want to discourage the average user from trying to replace the factory welded or soldered lithium ion cell for their personal safety. I also had a Shustar zoomable LED torch with a side COB light that came with a removable 26650 cell. I gave it away after I started collecting "real" flashlights. That was intensely bright from the candela POV but fell short when it came to lumens. It was advertised as having a "P70 wick" and someone had told me that it was a Chinese copy of the domed Cree XHP 70.2 emitter. That Shustar felt beefy in my hands and could be used to whack someone senseless with its weight. 😀
You can find the Shustar S-445 flashlight here. s.click.aliexpress.com/e/_DCXLebb Or Better LED Light Here amzn.to/4e1z4co
I would buy a basic C8 Flashlight and change the battery with a quality one. It's about the same price and a better deal.
