I am very sad today. I need some help/advice.
Apologies for the wall of text, but just trying to give as much detail as possible....
It seems like my HCigar VT Inbox v3 DNA75 is starting to flake out.
Either that, or 6 different LG HG2s of varying ages, are all degraded.
Yesterday I rebuilt my Goon v1 with 6 spaced wraps of 24g SS316L on 4mm ID, installed, wicked, and all was well (or so I thought).
Coil reads @ 0.38 ohms (as expected per Steam Engine and also confirmed on my Ohm Reader). After a few mins vaping this at 30w on the Inbox, the battery indicator starts flashing.
Never seen that before, usually it says 'weak battery' when the cell cannot provide enough power. Remember, this is a DNA75 chip inside.
So I pull the battery (LG HG2) and put it on the charger (Efest LUCv6) and it reads 3.67v.
So, puzzled I try another freshly charged LG HG2, that was resting in my stand (not in the charger) and put that in the Inbox. Same thing with the flashing battery indicator. When removed and placed on charger, voltage is 4.05v.
Ok. So I swap the Goon for the Wasp Nano (4 spaced wraps of 24g SS316L on 3.5mm ID, 0.29 Ohms).
Same problem on the Inbox with the flashing battery indicator.
So I lower the power down to 25w. Same problem.
Change it into TC mode with Djaquith's DNA SS316L v7 profile, set the mod for 420F and 35w. 3-4 puffs all is fine just like in wattage mode. Then, same problem with flashing battery indicator.
So, after some google-fu, found some info about changing the battery cutoff in Escribe down to 2.5v (default setting was 2.8v). Changed it. Now after first firing, battery thing is flashing again.
Also verified that the cell-type parameter was set for "18650 Litium-Ion" and not "Lithium-Polymer Pack". All these things were verified the first few times I ran Escribe.
So I set it back to 2.8v and open the Diagnostics Monitor in Escribe and am looking at everything while firing it, and it shows room temp is 109 F (not accurate, digital thermometer/hygrometer at my desk shows 80 F) and board temp is 190 F. Seem kind of high to me.
The mod and battery were both hotter than I've ever felt since I started vaping, moreso even than when I use a hair dryer to shrink a battery wrap...
I removed the battery, and let everything cool off.
Also to note, I never got the message from the DNA chip 'Too Hot' which I had seen a few times on my Lost Vape Drone.
After the mod cooled off, I tried 4 other NEWER LG HG2 cells, and still got the flashing battery icon.
So I removed the Wasp Nano, and put on my Kanger TopTank Mini which has a 1.07 Ohm 27g Kanthal build on the Inbox and set it for wattage mode at my normal 18w.
Thinking if something was fubar with the settings of the voltage cutoff, or the Escribe settings for 'maximium input amp draw' which is set to 32a. I had not changed this setting.
I figured higher resistance and lower watts should at least work since it is drawing less current from the battery.
But, nope. Fate was not smiling. Still got the flashing battery icon even with a 1.07 Ohm build @ 18w.
I've had the Inbox since Feburary, and bought it used but 'like new' here on VU (with the Wasp Nano) and it worked fine up to this point. Never been dropped, never left the house and it sits on my desk since day one.
I tried to open it via the 4x 1mm hex screws on the case, but one of them was apparently stripped and I could not get it out.
I wanted to see if maybe there was liquid inside or something came loose, but cannot get it open.
So now it sits unused, in a box on the side of my desk.
If I wanted to salvage the DNA75 board and some of the other parts, I will likely have to cut the case apart with a dremel, which could all be for nothing if something is fried with the DNA board now.
Any ideas what to do next?
Any ideas what the root cause of the problem could be?
Should I buy some brand new high-drain cells like Sony VTC5a's and see if they too experience the same problems in the Inbox?
Should I do a 'Factory Reset' in Escribe? (this will reset the default DNA75 firmware settings and purge all of the custom screens installed by HCigar, and I'm not sure how to back them up).
Please help me Obi-Wan Bonkers, you are my only hope...
