I left mine for around 24 hours (actually forgot it). Nothing exciting happened (like a BOOM). The red light stayed there all the time as well. Checked the battery was fully charge (actually it was 4.13 not sure if that how this battery charges full).Anyone know if, on "the latest version" (with fixed 510 and sleep mode,) there is any battery charge protection?!
I got a plain white-paper note in mine that reads "***Please note when charging this mod, the LED screen will not notify you that it is charging. If you would like to know whether it is charging or not, simple unscrew the back of the mod and you will see a red light glowing which means it is being charged. You will then notice that the battery indicator on your LED screen (when power on) fill sup after being fully charged."
So I'm NOT going to unscrew every time, that is freakin' dumb - if I was going to do that I would use my fancy charger, the point of the usb connection should be convenience. And I can see the faint red light through the small crack in the USB port...so its not really at issue. BUT that light never goes out, nor seems to change, ever.
SO...is it charging indefinitely? If I were to be reassured, by someone who knows (not assumes or guesses) then i'd feel better about leaving it overnight, which is by far the most convenient way for me to charge it.
Thanks in advance,

P.S. I asked the supplier, they said they don't know for sure, and if I am concerned about it I should use my Nitecore charger. Well yea...but then a really nice feature of this thing just went up in smoke (pun.)
BUT don't take my word for it. I'm not assuming nor guessing just telling you what happened. By the way when I bought it I did not get that paper I got the paper for polarity only.
So YMMV, do it at your own risk .
