Battery report:
I put in a Panasonic 3400mah NCR18650B in my Semovar on Wednesday at 5 in the morning.
Batttery is about 4 months old, and well used.
Nivel Chip 1.4, firmware 1.80.
Display intensity set to 2.
Button LED set to ON.
Battery cap inverted with spring pointing out.
Vaped all Wednesday at 12W
Vaped Thursday a.m. at 12W, then toggled down to 10W, then 8W for the rest of the day.
Vaped this morning (Friday) 5am to 8am.
Dead battery. Removed battery, re-inserted, got one vape. Dead battery.
Vape timer says 58 minutes of vape.
xtar VP1 reports 3.4V on dead battery.
Battery readings during this time showed 0.2V to 0.5V difference between unloaded and loaded.
No battery re-insertions other than noted above at the very end.
No errors, though I cannot see the window when I vape. It may have been throwing errors, but I noticed nothing from the vape quality.
I never got that far with my eVic, and my eVic was always at 8-9W.
I am very happy with my Semovar battery life. And I am going to stop neurosing about battery voltages. If I swap in a new battery every morning with my breakfast beer, life will be good.
