Perfect for your kit and overall the best battery life by far. Totally recommend

By Sam from London

Still my favourite for RDA (31 January 2020)

For RDA/Dripping, these are still my favourite. Just got a new set after around a year. Absolutely true to mah. Solid batteries. Accurate drainage on both batteries in all dual mods I have.

Quality (10 December 2019)

Been vaping littler over a year and have only ever used these Samsung batteries and never had any issues so I would highly recommend these.. Delivery was next day and included 4 rubber battery cases for the 4 batteries I ordered for free so can’t go wrong. Thanks to the guys at vape club.

By Stu from Edinburgh

Does the job! (28 October 2019)

If you're new to vaping and wondering which batteries to buy these are normally a solid choice. Pretty good across most mods (always check your manual first) and charge at a good rate. Genuine and highly recommended.

By Harry from Walton on the naze
