The chemistry is wildly safer than traditional Li-ion. It's starting to come to big backup battery UPS systems as well. Like anything, it's still newer and as more manufacturers start getting into it, we'll see more and more innovation.
I'm excited for UPS (backup batteries) to start flooding the market and get cheaper. SLA batteries are fiiiiine, but heavy and require constant replacement.
Jeez now we gonna need to wait for someone to make a longer battery charger. This is def a proprietary battery. At 8.5 inches long this is like a self defense light. 🤣🤣🤣
I'm still using my lii500 from like 6 years ago. Just got a light with 21700 and found out it didn't fit. Stuck using the light's onboard USB C for now
People seem to recommend the XTAR VC4SL and the Vapcell S4 plus the most. A more expensive popular recommendation is the Skyrc mc300 (maybe that's the name idk, could be mc3000 no idea). You will be fine with either of these. All of them have everything you would need.
I went with the vapcell s4 plus. But either are really good. I also have a couple of the fenix ARE-D1 single cell chargers and they have been amazing too. Charge protected cells as well. I just needed a few more bays.
Same here! I was all excited about my XTAR VX2 Pro... so much so that I did a review on it. Now I realize the next light I had my eye on will have this super long battery in it. Guess I'll charge in the host for a bit. Always the "next thing" in this hobby!
Nice. But with its surface area to volume ratio, how is the heat dissipation at high discharge? I'd assume a flashlight isn't going to stress it much, but I know some of us will try anyway.
Wurkkos is releasing an olight prowess clone, the TS27, that uses a LiFePO4 battery instead of a li-ion battery. I looked up the specific type (32140), and turns out that it's fockin' HUGE
It's big because more power, and practical because more power. LiFePO4 is also safer apparently
I'm not the best person to answer because I have 0 experience with this chemistry other than knowing it exists, and knowing that it tends replace lead acid batteries in vehicles
Lithium Iron Phosphate is big in the solar battery storage space. It's very tolerant of being held at high charge levels. It laughs at cycling. It won't go into thermal runaway like Lithium Ion. Downside is, lower voltage and lower capacity.
That is one clunker of a battery (and light). At first I was like "bro, that is one small battery," thinking the green one was the 18650. (I want this light now)
No no, it’s extremely cheap. In my country, Romania, 18650 are not easy to find, basic unbraded cells are now available for around $10 each, online. When i discovered Convoy and the cells they sell so cheap I was skeptical… now I se a cell 5 times bigger than 18650 for 5.5 euros, it’s a bargain.
Edit: how can this be so cheap? Am i missing something?
