I use a single 18650 mod, and am interested in finding the best (longest between charges) battery for my style. Wismec Sinuous P80 Approx 10W in TC mode, 410F SS316L 28 ga, 2.5mm id, usually 0.78 ohm 150-200 hits per day, around 6 sec per hit Approx 2 ml juice per day Got the P80 a couple of months ago, and have a Nitecore charger on the way. In the meantime, I've been using the USB charger (yes, I only charge when it's attended). I'm using the Samsung INR 25R battery. I know that using the internal charger, especially since it's a 2A quick charge, certainly isn't getting me the longest time between charges, and is shortening the useful life of the battery. Most days, a full charge will just get me thru the day. Sometimes, I need to charge a few minutes when I get home from work to make it thru the evening. So with this style/power of vaping, should I go up to a 30A battery, look for specific mAh, or what? What would give me the longest time between charges? Would one of the Sony VCT or LG batteries be better suited for me? Thanks in advance for any advice/recommendations.
