I've poured over the internet to include reading pages and pages of posts on this light but have not been able to find someone to confirm what the best 18650 battery to use in this light is. I've determined that it has to be a 2200 mah or smaller in order for the length to be below 67mm which is the max recommended by Zebralight. I don't want to just poke and hope. I've used Aw's and Redilasts in the larger sizes with success in other lights. Please let me know which 2100 or 2200 batteries that are 67mm or shorter are best, thanks.
