I need a change out soon but I'm not sure what to buy. When I got the device originally I got 4 900mah trustfire protected 16340s which didn't fit. The 500mah LiMN's work great, but they're only 500mah and they're quite expensive. I've looked at LiFPO4's, but they seem to be 3.0, not 3.7V's. The adaptever site tells what length and diameter fit but that's not particularly useful when ordering online.
So how's about it? What can I use for 3.7 V vaping on the adaptever?
