Rechargeable 18650 batteries
With so many choices and specifications, battery shopping can be overwhelming. The simplest method is to look for something with a higher mAh number if you want a longer lasting cell, and a higher amp rating if you want a stronger cell. If you mostly vape at higher temps, focus on the amps, or power. If you vape at lower temps and want longer battery life, get a battery with a higher mAh rating. Finally, if you use a box mod with more than one battery, it’s best to buy batteries in sets that you keep together and charge together, treating them as one.
The Samsung 30Q 18650 battery is an excellent high capacity cell for those looking for long battery life. It is rated at 3,000 mAh with a 15 amp continuous discharge rate. The Samsung 30Q is great for box mods, and provides long run times at low to medium temperatures. If you prefer higher temperatures and are a Samsung loyalist, give the Samsung 25R a look.
