Hey guys - for all of my Provis, these have been all I've used almost since Day 1.
3000mAh 18650 Battery 20A-35A Li-ion 3.7V Button Top Rechargeable High Drain H-IMR - Orbtronic
^^^ Button tops, not flat ^^^
You're thinking of the Billet Box, KAS, and the issue where Mr. Wong decided it's acceptable to have mis-labeled batteries (16340 that SHOULD have been labeled 16350).
If AW were the last batteries on earth, I'd buy them again. Other than that scenario though...
Okay I thought you were using the same company for both battery sizes. I think I have that one book marked as well. Do you know of a good button to 18490/18500, other than the one I quoted? It looks like Orbtronic does not have the button tops.
