I have a led lantern that takes 8 D cell batteries. after it got left on a few times over night and ran through 16 D cell batteries in 1 weekend ($$$) i figured this would be an easy project to convert to 18650's with a little USB charge controller so i could plug in the lantern to recharge. I searched the forums a bit but didn't see a bunch of other posts with the same thing.
originally i just assumed that a 18650 cell would stomp a D Cell battery in amp hours, but after a bit of checking it looks like a D Cell battery is between 12000 - 18000 mah (depending on load)? so it looks like i might actually lose run time if i swap out the D cells.
lantern seems to run on 6v (not confirmed yet) given that it will run on only 4 batteries installed.
