Is.it a v2 SVD?..

Mine is similar but has a clear led fire button and says it only goes down to 3.3v when mine goes to 3v which I doubt I will ever go that low. Other than that they are the same.
I know the short tube works with a 18650 but looks kinda odd compared to putting the big tube on for the bigger batteries. As for the black button it would work but I like seeing what color mine lights up indicating the battery level.
