Most devices & gadgets are rechargeable nowadays. The only thing I have that still requires batteries is a headlamp but even those are available in rechargeable varieties. House smoke detectors need a battery too.

I’ve only recently stumbled on 18650’s potential (lol) by using the 4Ah Kobalt 24v batteries for some experiments with solar, 12v loads, and inverters. Holee hell nuts. Theoretically around 44amp continuous draw in 4Ah arrangement (though I’m aiming to be well under 30 in most circumstances).
Also need to mod kids power wheels with these.
Wait until you hear about 21700s.
I was looking into them! Basically I’m just trying to utilize what I already have with my kobalt batteries for odd-end projects and camping, etc. The price-to-performance for the XTR line that has the 21700s just isn’t justifiable for my use-cases.
