I saw on a rechargeable battery review that the EagleTac 3100 mah, 18650 battery was highly rated. I have some AW 2900 mah 18650's but find that they don't always completely charge in my charger. The EagleTacs have a button top. Has anyone ever used these in a wood mod? If so, I'd love an opinion on using them with a mod. Thanks in advance for any responses.
