2 x Samsung 25R 18650 High Performance Rechargeable Lithium Battery

The Samsung 25 R rechargeable lithium battery provides a consistent power source with its 2500mah capacity making it an ideal battery for vaporisers.

This battery is also one of the top performing batteries used in sub-ohm mods, power banks, torches and other devices. 

For the best charging it is recommended to use a Smart / Intelligent Charger to maintain the battery’s high performance. This is because the IMR cells have a low internal resistance and should not be charged above 2.5 volts, which can happen with an inferior charger.

The Samsung 25R was still a top selling battery last year (2019) after being a favourite on the market since its release in 2014. It still provides a great balance of 20A current rating and capacity.

Its battery cell is of continual good quality and high reliability. Dubbed the "Goldilocks" cell, it does everything a battery should do and does it well.

The 18650 batteries are the most popular for vaping owing to their reliability.
