E-Cigar - Green Led Flasing?

[Jaaxx]

I've got a DSE701 from litecigusa that sometimes flashes a green light from end. Then end where the orange led is.

It used to do this when the battery was going dead, now it sometimes does it with a fresh battery for about a minute or 2 then works normally. I can't find any documentation on this. Anyone know?

That's kinda cool... my puresmoker cigar, nor my Blings have any other lights than the red one. A dead battery indicator would be pretty handy.
