I've done a few searches with little turned up. How many different 18350 batteries are there, so far I find only the IMR ones at 700 mah. I've been using a few pocket lights with tubes allowing both 16340's and 18350's, one dropin is at 5.6 amps one at 3 amps and another at 2.5 amps. I would perfer the slightly larger if a little greater capacity and discharge can be had. Any help will be greatly appreciated, thank you.
