Hey guys earlier I mentioned in this thread that my sig eats up batteries a lot faster than the SXM and also needs to be set to a significantly higher wattage and/or temp to achieve a similar vape to the SXM. Both of these issues started becoming progressively worse over time, and it started doing something my old Smok M65s did; giving a low batt warning while firing even with as much as half a charge left.
Well, I feel like a complete idiot now as I've figured out the problem and it's a familiar one to anyone who put their time in with mechs. Contacts. The thing has copper contacts that tarnish really fast and cause two problems:
Resistance reading is higher than it should be because of tarnish/corrosion on the 510 center pin causing inconsistency and inaccuracy with the vape quality.
Being unable to deliver the higher current demands as the battery starts to drain, because the battery contacts are copper as well.
After a quick polish with my trusty old eraser set I used on my mechs back in the day it's able to fire at 55W with a battery that barely registers on the meter, and the vape quality is very similar to the SXM at similar settings.
It's been so long since I've used mechs I've just completely neglected contacts on all my APVs, most of which I sell/trade/give away after not too long, and they usually have brass or stainless contacts that don't tarnish as fast. But the sig definitely needs frequent polishing of the 510 center pin to ensure good performance in TC mode, and less frequent (but still more than normal) polishing of both battery contacts. It was really disappointing at first because performance out of the box was great but quickly started getting worse, I know this may be very obvious for some people, but it totally slipped my mind and I'm not green by any means!
Sorry for the long winded post BTW!
