Thelema DNA 250c

[drizzyigor]

Hey, So i got this thelema and the battery percent is showing 4-8% on it but on a different cigarette it's showing 66%. After a soft and hard reboot it shows 66% on the thelema but after like 30 seconds it goes down back to 4-8%. Anyone have any idea what could be wrong?

Also cell 1 keeps jumping while cell 2 is still

That's one of those relatively rare issues, that even I wouldn't be able to come up with good search terms (but I have seen it a posted here). I'd suggest you open a Help Desk ticket.

Show me, like before.

Here you are, the second battery isn't as charged but it should show more than 4% right?

Thanks, great. Your cell 1 is only at 3.5V. That % is based on the lowest cell. Charge both fully, hopefully externally and try it then.

Okay i will and i'll give a reply

So after charging the batterys both are charged. When plugged it shows 93% after a reboot. While disconnected from the PC it shows 52%. The screenshot is made while taking a puff, While not pressing the power button the the cells are not jumping anymore. Any ideas why the battery % is going to 52% while disconnected? And if i don't fix it can it be dangerous?

Were both batteries charged externally? And what make and model are they?
Look at each battery's voltage right now. Unplug your mod, and swap the battery positions in your mod.

If cell 1 (old cell 2) still shows lower than cell 1, then we know something is wrong with that area. Either way you might want to clean all their contacts with Isopropyl alcohol (IPO), or even better, semi dismantle the mod and look for ejuice and wipe down the area around the bottom of the board (both sides), those 2 fatter connections and those 5 small ones. There might be white connector which you can pull apart off the board. Wipe down everything.

Looking at your screenshot, ideally/regularly they should be parallel. When you take a puff they should both dip/sag equally.

No, it's not dangerous, but it should be fixed. Because that % is based on the lowest cell, your mod will give you a weak or check battery much sooner than it should, and stop working.

Similar to this.

So i tried newly bought batteries but it's still the same i'm guessing it's something in the insides but i have no idea how to open it, even after unscrewing everything i couldn't open it up
