510 Mega Battery from Madvapes

Do these have an auto shutoff feature? It seems like after 10 seconds the LED blinks like the battery is dead...but after sitting for a second it works again

I mine do. I also got them from madvapes. Link : 510 Mega Battery, Red LED

Although 4.5 months ago, when I got mine, they had blue LEDs. They start flashing and you have to wait a bit, then they work again.

yes, 8 to 10 second cutoff and if you hit the cutoff, there's about a 5 second wait.. I pump the button when using 3.2 ohm cartos, seems to reset the timer as long as you don't hit the timeout..
