I enjoy 1xAA lights and own a good many. I use eneloops or LADDA cells and have been happy with them. That said, I’d like to give 14500s a try (almost all my 1xAA lights are 14500 capable). I don’t need the ones with a built in micro-USB charging port as I recently picked up a charger at SBFlashlights’ sale (Xtar MC1 Plus). Here are my other desires:
1) protected cells
2) button top
3) under 51mm in length. Eneloops are 50.4 mm and I’ve noticed that many protected 14500s are around 52mm (or longer). I’d prefer 14500s that are under 51mm so as to easily fit and not overly compress the springs in the lights.
4) high enough drain to allow for turbo mode
5) reasonable price (shipped) for a pair of cells
At Battery Junction, I saw a few protected 14500 cells with lengths under 51mm: Xtar, Nitecore, and a couple of different Klaurus cells. The Xtars looked attractive price-wise. https://www.batteryjunction.com/search-results.html?keywords=protected+14500&x=0&y=0 Availability at Amazon would be a plus due to free shipping.
I’d appreciate recommendations for 14500 cells that meet these criteria, as well as where to buy them.
