bigcloud80 Posted May 19, 2021 Report Share Posted May 19, 2021 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. Link to comment Share on other sites More sharing options...
dwcraig1 Posted May 19, 2021 Report Share Posted May 19, 2021 The 18650 battery setting is correct, it more or lees just means round replaceable type cell. The Cell Soft Cutoff is set at 2.75 volts normally with a round cell. What is the standing voltage of the cell when it reports 40%? Can you post a snippet of Device Monitor firing under the conditions described in your post like the one below? Note on mine the voltage dropped to 3.52 while firing at 45 watts. Had it dropped to below 2.75 volts the low battery error should display. 2 Link to comment Share on other sites More sharing options...
bigcloud80 Posted May 21, 2021 Author Report Share Posted May 21, 2021 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.

BillW50 Posted May 21, 2021 Report Share Posted May 21, 2021 There is something wrong between the battery connections and the wiring to the DNA60 that has high resistance causing a voltage drop. Cleaning the battery contacts might be all that is required. 2 Link to comment Share on other sites More sharing options...
dwcraig1 Posted May 21, 2021 Report Share Posted May 21, 2021 My guess is there is a problem with the wiring between the battery and board. Look first at the battery contacts. Does the battery fit snug? There may be a cold solder joint where the wires solder to the board. Does the mod use a ground wire from the negative side of the battery to the board or does is use a chassis ground? Is is not because it's a 21700. 2 Link to comment Share on other sites More sharing options...
bigcloud80 Posted May 21, 2021 Author Report Share Posted May 21, 2021 It's a stabwood, so can't check anything but I'll contact the modder and send it in for a checkup 1 Link to comment Share on other sites More sharing options...
dwcraig1 Posted May 21, 2021 Report Share Posted May 21, 2021 Does the battery cap screw in? If so try cleaning it's threads and the corresponding threads on the mod with a q-tip and alcohol. Look down inside using a light and see if the positive battery contact looks clean. 1 Link to comment Share on other sites More sharing options...
