I was looking at those and was thinking those would be the right ones and it would give me some.extra wattage room I've been reading moochs battery cell info but something's I got confused on so i thought I would post and ask just to make sure.. thank you will those ones last a full day ? If I vape around 45-55 watts
Battery life is more about puff count and puff length with wattage being a factor. I do know that the HG2 will outperform most 18650's in an ecig mod.
I vape at 10W, so I can't tell you how long the HG2's will last. I get morning until about 9pm on a set of HG2's in my Innokin Proton. It's a 235W mod, so i'm in buck mode all the time.
Someone here will be using the same hardware as you and can give you some first hand info.
Single and dual battery mods vary on the amount of power that the mod's electronics use to provide variable wattage and TC vaping. I don't really see a doubling of vape time in a single or double battery mod most of the time. I'm sure there's a sweet spot where the mod's electronics are coasting. The logic in a mod has to boost or buck (reduce) the output from the cells to go up and down in power at the 510 connector. All that electronic manipulation eats some power from the battery. I have simple single battery mods that can take me from one morning into the next day and others that need a battery change the same night. At my 10W vaping style I'm in buck mode all the time. It's all about efficiency in the circuitry.
It's always a good idea to keep a spare set of batteries in a plastic battery box in the car when you are away from home. Sometimes, I need them and sometimes not, but they are there if I need them.
