What are the Benefits of Using 21700 Batteries?

When it comes to our 21700 batteries, we believe that these particular cells are the ideal product for VV / VW mods as well as various other high power configurations. In comparison to the 18650 batteries, it has a much larger density which allows more energy to run within your appliances for longer. The 21700 battery can last anywhere from 3-5 years and can be recharged at least 300 times and sometimes more, depending on how frequently you use your vape and the batteries. Not only will these batteries help your appliances run efficiently, but it will also ensure that they provide a smooth operation when in use all throughout the year.

Which 21700 Battery is Right for you?

To date, we believe that one of our best 21700 batteries is the Samsung 40T as it has a 4000mAh capacity and a 25A discharge rating, therefore, providing you with long usage on a single day charge. In addition to this, it has a nominal voltage of 3.6V and can easily be recharged through the use of an external battery unit. It is important to remember that no matter what cell you purchase, you should always store them correctly in a cool, dry place that is not exposed to direct sunlight or harsh temperatures as this can warp and damage the cells dramatically.
