>>1398237I was at Walmart the other day and found pic related in the garden section by the solar powered lights. $14.
I found a drill battery on sale and got a bunch of 2000mAh Samsung cells for $4ea. Not button top, but I used them for other projects. And if you cut the tabs right, they will work the same as a button top.
Also Walmart has these power banks for $5 that are made of a little board and a 3250mAh 20650. Ripped a couple of those apart and they fit in my flashlights with the 3xAAA carriers. They actually fit better than the 18650 because they’re the same length but a little fatter.
