Just got in a bunch of new batteries to try out. I bought them all at goinggear.com and got free shipping on my order, though the order took its sweet time - a full week. But everything arrived safely and as advertised, and so far I'm really pleased with the new batteries I got. The wife also picked me up a couple Panasonic hybrid 18650's from one of her orders, so we really scored on 16340 and 18650 lithium-ion and hybrids.
The EagleTac 3100 was 15 bucks a piece on goinggear, but holding these in my hand, I can see where that money went.
I got just one of these Nitecore 18650 batteries to try out. They were only 10 bucks a piece, and the 2300 capacity is fine for the tactical flashlight I keep on my nightstand. 2300 seems low, but most battery makers overstate their capacity, and this one if anything is probably understated. They look like a really good value, so I figured I'd try one and see.
Got these EagleTac 16340's for my EDC type flashlights and as a backup for the wife's e-ciggy.
These hybrid IMR / Li-Ion batteries look interesting as well. I'm curious to see how they hold up. They are higher capacity than IMR chemistry and more stable than lithium-ion. I guess I shouldn't be worried that they are unprotected?
