Are there any posts that list which battery types tend to work with which manufacturers?
If you had to buy only 1 type of 18650 that would be most likely to be compatible with lots of batteries, which would you get? (I’m assuming non-protected and button top? maybe flat top?)
I know:
- some zebra lights can’t fit protected
- some nitecore lights require button tops
Any other good general warnings? Would you say button tops or flat tops are more compatible across the recommended lights on here?
