Your E-Cig battery is one of the most important parts of your vaping device. The battery you choose will determine how long you can vape for between charges, how much vapour you can produce and the clearomisers that are compatible with your device.
Larger capacity batteries will allow you to vape all day. Larger batteries usually have higher capacities, while smaller batteries usually (but not always!) have lower capacities and will need to be charged more often.
