I'm confused about this.
Thanks for shedding light on this.
Thanks for shedding light on this.
I have been debating getting a 2 cell.SF but,the.G2 I had was awful for runtime.Give some info on the lights that you are using. We may be able to recommend 3.7v 16340 li-ions as an alternative
There aren’t many 3v CR123 rechargeable options. As Fivemega said, the keeppowers are an option, but they may end up being longer and have fitting issues because of the usb port (but not certain). Surefire makes a set of rechargeable CR123s as well Here but they are only 450mah. Work great but runtimes suck
I never had an issue. They work great but you just don’t get long runtimesSurefire 123a rechargeables (SFLFP123) are probably high quality.
LFP123s meet my needs very well, but it's probably due to my perspective. My own experience in engineering has taught me that it practically always requires 'prioritized tradeoffs' to achieve the best results, and I've never found a way to 'have it all'. If anyone finds it, please 'PM' me! I get significant (to me) advantages from LFPs in a number of my flashlights (and other things designed around a 3V power supply), and I'm happy with what I get relative to the capacity I trade off for those (in some applications). Do I use them in all my applications? Of course not. That would be another absolutist view which would not serve me well. I think it's a perspective thing. Many things are relative, not absolute. Some may not have any applications where LFPs pay off, but many like me do. If I was in that first group, I would not use them.I never had an issue. They work great but you just don’t get long runtimes
I prefer LFP cells. They are more tolerant of temperature swings than the other rechargeable lithium chemistries, have an acceptable self discharge rate, work as a direct replacement for 3v primaries in most cases, have a super flat discharge curve (almost rendering regulation pointless), and— most importantly— are unlikely to burst into flames no matter how much you abuse them.
I think their only downsides are lower capacity and lack of market acceptance. I wish I could find a dedicated LFP charger, or 16650 LFP cells. They just don’t seem to exist, anywhere.
