I'm using a Fenix LD20 now but I'm considering an even brighter light. I'm a total newbie when it comes to 18650 Li-ion batteries, CR123A batteries and RCR123A batteries and I'd like to know the pros and cons of the three.
Are there rechargeable versions of the three available?
If so, which one is easier / safer to recharge, if I use top quality brands?
I live in the tropics so cold weather performance isn't a factor. The primary use will be daily carry and security work. What I'm concerned about is the best bang-for-the-bucks rechargeable battery choice, one that will be easy and relatively safe to use. The lights I have in mind is a Fenix TK11 or a Fenix PD30.
