I got it. Thanks. Can u list me some 20700 batteries, With best
efficiency? cuz my friend told me that ncr20700a is one of the best.
I only buy brand batteries, not rewraps. The only 20700's I have experience with are the Sanyo's. The below is very simplistic. There are a lot of factors affecting battery performance. I would watch Mooch's YouTube videos.
20700A - 30A max current, 3300mah capacity. High wattages, this will perform better and be safer due to the 30A draw. The 3300mah capacity is also great for a battery capable of a 30A output. Probably the best you will find currently in a 20700.
20700B - 15A max current, 4200mah capacity. At lower wattages (not pulling more than 15A), this battery has an additional 900mah capacity over the 20700A. So since I almost always vape below 30w, this is a better battery to me than the 20700A. In theory it will last me longer than a 20700A (since it has higher capacity), you just shouldn't draw more than 15A from it. Batteries typically perform better and last longer when they aren't stressed to max specifications.
It's really all in what you need the battery to do. If you need high current, the trade off is the battery will have less capacity. Lower current batteries can have a higher capacity, lasting longer. So you make a choice based on your vaping style.
Sanyo is also coming out with the 2070C (impatiently waiting). This will be a 35A battery with 3500mah capacity. It's not available to us yet, Mooch hasn't tested it that I'm aware of. Based on the numbers though, it has higher current capability than than the 20700A, and also has an additional 200mah capacity. Theoretically, this battery should outperform the 20700A. I will pick some up to try them when I can find them, but for low wattage use, the 20700B may still be a better battery to me since it has such a high capacity.
This is looking at it in simplistic terms though really. A batteries run time really depends on many factors. Mooch rates them not just on these numbers like I used to compare them. For example, sometimes a battery that may have better stated specs, may not hit as hard for as long before needing charged than another batter with similar specs.
Make sense?
