The batteries function is to provide power to the E Liquid Cartridge to produce thick and dense vapour. If the battery is to small there isn’t enough vapour and if its to big it doesn’t really feel like a cigarette. So to get the balance right between size and power is the key to a great user experience.
The K7 series is the latest in battery design and rated at 145mah.
