35 watts? Your battery life should be awesome. Rock on.
I boosted the power to 50w this morning once I found a comfortable restricted lung hit/air-flow setting on the Maker, ~6 hours ago. Been hitting continuously the past 2 1/2 hrs, really nice Mod and I'm still massaging it between hits.
The battery was @ 95% this morning, and now is registering 31%, when they arrived, they held a charge of 3.99v, and I charged them full/ 4.2v before their first use. Once the icon blinks, I'll report back.
I just refilled the bottle, using a modified "Peng Method", after inverting and squeezing out the air, I inserted my needle-tip juice bottle, and rotated them 180 degrees (d), letting the SS bottle, now right-side up, suck in the juice. Once full, I rotated feed/juice bottle 90 d and removed the tip with no leakage, it filled the SS ~80%, good enough for me.
I'm glad I changed mind and tried another regulated B-F Mod, thanks again, it's been nothing but pure bliss so far.
