As far as sheer firepower, I like and only use AW IMR batteries. Sure, less runtime, but safe chemistry and heavy load tolerances are a good selling point. For good runtimes, I use Sanyo Eneloops (1500 cycle ones). Less firepower, but safe chemistry and good runtimes. "Safety Above All." Baby!
I see. I was referring to these IMR cells and that's why I said the price is good but since AW has protected IMR then I might just go for those instead. Although they cost quadruple but at least I know I'll receive protected cells that should last me some years.
I'm into the RC hobby so I know the do's & the don'ts of lithiums.
I would not count on a circuit board to protect me from my own stupidity, but the protection is a nice thing to have which could come in handy in some circumstance. You're right, the circuit is just a last resort safety step and one should not be relying on it.
Anyways, I'll just go for couple of the AW IMR for now to make the E03 a true pocket rocket.
The AW IMRs are an excellent choice, and your post above is very true. I'm glad you seem to be an experienced user, as I'm always a bit apprehensive seeing the newer members naturally gravitate towards the most powerful torch, and the cheapest cell to accompany it. :)
Haha, I've been using Westinghouse Lifepo4's from Walmarts solar lighting section. They are a bit hit or miss. I've had a couple cells die just sitting in my drawer, but I also have a couple that are still going strong after about 2 years.
The Bestinone's tested out pretty well in Mitro's test (below). $8 for a pair with free shipping is a pretty good deal. Most IMR's are not protected because they don't have thermal runaway problems of LiCo cells. I have some batteries, but not a Xeno to test them in. I would worry about using an IMR in a direct driven light because it might burn out the LED. Since you asked for the best, the AW IMR's are certainly better, but cost more.
