5 Best 21700 Batteries In 2023 [by use case]

Molicel are a well-known brand in the world of vaping. Maybe not quite as commonplace as companies like Samsung and Sony, but for a company almost entirely dedicated to rechargeable battery tech it’s impressive that they’re able to compete with and – in some cases – excel beyond the Big Brand Names.

Morever, Molicel aren’t limited to 18650 batteries; Molicel’s P42A boasts an impressive balance between high capacity and amperage.



The Molicel P42A has an internal battery capacity of 4200mAh, very ample and capable of providing many hours of charge for your external battery vape.

The P42A has a discharge rate of 30A, making it very well suited to sub-ohm vaping and power outputs which are likely to put the battery through some stress which it’s designed to handle well. The amperage may not be the kind of wattage an RDA requires. though.



Molicel were responsible for the creation of the very first rechargeable lithium batteries, and so you can be assured that when you buy Molicel you’re buying literal decades of experience in the manufacture of safe and reliable 21700 batteries.

Although it’s unsurprising that a battery manufacturer as storied and experienced as Molicel would release a 21700 battery that was perfect for intensive vaping, it’s very pleasing to see that they haven’t had to make any great sacrifices when balancing mAh and A.

High Amperage: 40A easily capable of handling any intense requirements
Dual Batteries: Perfect for marrying a pair for long-term use
Long Lasting: 3750 mAh enough power for consistent use

It’s often a good idea, when seeking out batteries for a dual battery mod, to purchase two batteries at once and ‘marry’ them, meaning you use and charge them together constantly to ensure the longest battery life possible.

Golisi are here to meet this need with a frankly stunning pair of batteries, the Golisi S35.

The S35 battery boasts an absolutely awe-inspiring 40A of amperage. This is easily enough to handle any amount of stressful output you intend to put the battery through, capable of producing consistent competition-level clouds with ease.

Even better, Golisi have somehow solved the issue of ordinarily having to sacrifice mAh for A. The Golisi S35 has a power capacity of 3750mAh, not the highest in the world but astonishingly high for a battery with such a high amperage rating.

The Golisi S35 is perhaps one of the best battery bargains you’ll ever encounter; two stunningly powerful and high charge batteries that won’t let you down, no matter how many fat clouds you hope to puff that day!

Good Amperage: 35A is a very high and capable of handling frequent high stress levels
High Capacity: 3000mAh, while not the highest, is still good for all-day-vaping
Competition Grade: Professional quality power and longevity

Ordinarily when looking for a 21700 battery that’s capable of handling wattages above 100W all day you need to accept a sacrifice in capacity, as high amperage batteries are rarely able to hold a large amount of charge.

But Vapcell are here to smash those assumptions! As a matter of fact, you don’t have to make the sacrifice! Their T30 battery will absolutely not let you down.

The Vapcell T30 has a very high amperage of 35A, which is easily enough to handle the highest wattage outputs your mod can manage.

But it also comes packing a 3000mAh capacity! While that might seem lower than some of the other batteries mentioned today, it’s a very high amount of power capacity for a vape designed to withstand intense, competition-level cloud outputs.

While some vapers out there, both sub-ohm and MTL, will possibly be looking for a battery with a slightly higher mAh, those of you who rarely go lower than 100W will want to opt for a battery like this because it is absolutely designed with your requirements in mind.

The Vapcell T30 is a cloud chaser’s dream; capable of handling intensive outputs and also lasting several hours before requiring a charge!

Brand Recognition: Sony is an extremely well known brand with years of experience
Long Lasting: 4000mAh enough power for all day use
Durable: Solidly built batteries that last a long time when well maintained

Sony need no introduction; one of the most recognisable technology brands and manufacturers on the planet, they carry with them a hefty payload of name recognition and consumer confidence, and taking a look at these batteries you can quickly see that the faith is not misplaced.

The Sony VTC6A 21700 battery has an internal power capacity of 4000mAh, a stunning amount of charge bound to provide hours of heavy vaping action.

And emphasis on heavy, as the 30A discharge rate of the battery means that it can handle those more stressful high wattage outputs favored by the cloud chasers out there.

There’s a reasonably good chance that, if you’re looking up the best 21700 batteries, you’re probably familiar and fond of high-powered sub-ohm vaping. Rest assured that the Sony VTC6A is easily enough to handle almost any output level for your vape kit.

High Capacity: 5000mAh is an absurdly high charge, particularly for MTL vaping
MTL Specific: 10A not an advisable amperage for sub-ohming
Durable Build: Solidly constructed

It’s easy to assume that 21700 batteries are only for the hardcore, the cloud chasers, the sub-ohmers kicking out vast and massive plumes of vapour, but you’d be wrong!

BAK are back in town to prove that any vaper can seek out intelligent power solutions. And, it’s fantastic to see they are supplying 21700 batteries which are ideal for MTL vapers.

The BAK N21700CG-50 has a phenomenal power capacity of 5000mAh. You’d be hard pressed to find an external battery that can offer you more than that!

A sacrifice is made to attain that high mAh; the N21700CG-50 has a very low amperage – clocking in at only 10A. 10A is absolutely not suited towards sub-ohm vaping, and we do not advise using the battery for such purposes.

However, if you’re an MTL vaper who intends to keep their wattage in the moderate 9-13W range then it’s a perfectly adequate amperage for your requirements, and with 5000mAh to play with you’re looking at several days of MTL vaping action!


The BAK N21700CG-50 is the best vaping battery for the MTL vaper who only wants to charge their vape twice a week!
