I got two AW 2000's as well and they are too long !! First of all AW has a slight fluctuation in their battery height (even the 1600's but they're under the 65 mm mark so no body noticed).. As one of my new AW's is .030" taller then the other 2000 mAh AW (yes, they are genuine bought from super t's) so I took the shorter of the two and tried it in the LT and it was too long and you could see a space, crazy thing is, the same batt put into a second lava tube fits.. So you got two variables to consider; how tall will your AW 2000 battery be ?? And how much length do you have in your tube when they cut it during manufacturing ?? It's a craps shoot !! I personally believe Volcano should make a better end cap that has a bit more depth, then people could use any 18650 they choose (although I still would choose the IMR).. IMHO I think Volcano rushed these to get them out before the Holidays, and I KNOW they'll have a Ver. 2.0 out soon, it's their only way to keep the hype that they are losing daily from L-Ryder selling them wholesale to everyone...
