So, what makes the 18650 lithium battery the ideal choice for vapers? Why not the preinstalled batteries, such as you see in ELeaf Mini, Kamry 20W etc.? They are compact and yet fairly powerful. Moreover, you don’t even need to buy new batteries or external chargers. You can start vaping as soon as you buy your vaping gear. What’s more, you don't have to worry about any safety concerns with the built-in batteries.
Well, while the built-in batteries might offer several advantages, they are pretty much disposable. Once they deteriorate, you have to throw away the whole unit. On top of that, the 18650 lithium battery give you a lot more control over your mod and battery quality. The moment you load high-quality batteries, your vaping experience goes through the roof. You can choose any type of batteries (either high amperage or high mAh – which we’ll discuss shortly), and you can replace the batteries when they reach the end of their lifecycle.
