[DNA 60 battery drains overnight]

My SVA Cinque Terre (DNA 60) drains overnight. It's only draining the battery when there is an atty on top. (tried different atties)

I already tried to clean the board with Isopopanol alcohol as I read in other threads but no succes.

Installing an other theme is not an option because there is no usb port on the mod.

I have another Cinque Terre (DNA 60) with the same theme on it and with that mod I don't have issues, so I guess it's not due to the theme on the mod.

I really could use some help here, any suggestions?

thanks in advance.

It's a stabwood, so can't check anything but I'll contact the modder and send it in for a checkup

The battery voltage is at 3,6V and it drops below 2.75V as you said.

But I'm only vaping at 17Watts with a (1ohm coil). I think a DNA60 just wasn't made for 21700 batteries.

I got a few other DNA60 mods powered by a single 18650 (Sony VTC6) and I can vape the same amouth of juice with the same tank and build with an 18650 battery as on this mod with a 21700.

these are the 21700's I tried so far.

Molicel INR21700-P42A 4000mAh - 45A

Samsung INR21700-50E 5000mAh - 10A

Vapcell INR21700 4000mAh - 30A

When I use a battery adapter with a VTC6 18650 on this 21700 mod it seems to perform the same as with a 21700.

I got a custom made dna60 mod powered by a 21700. 

Once my battery is at 40% it's starts blinking after every puff. The modder doesn't have a clue.

I think I have this issue because on escribe it says there is a 18650 in it.

I can't change it to 21700 the only options I have is Lithium 18650 or Lithium polymer.

Is there someone with the right settings for my device? I know the Thrill plus is also a DNA60 powered by a 21700.
