21700s are the latest batteries for vaping. They are considered an upgrade over 20700s and 18650s because they come with a larger capacity and can generally be operated at higher wattages. With more and more companies coming out with 21700-compatible vape mods lately, these batteries are considered by many to be the future of vaping. Outside of vaping, 21700s are mainly used in the electric vehicle market (electric bikes and cars).

Most of the batteries that don’t come from long-time electronics manufacturers such as Sony, Samsung, Panasonic and LG, are rewrapped cells. Many of these come with exaggerated specs, so always do your research before purchasing batteries for your vape.

Note: Always practice battery safety when operating powerful lithium-ion cells. Make sure you understand Ohm’s law, especially if using mechanical mods. And only charge vape batteries in external and dedicated battery chargers.

The Samsung 30Ts are the best 21700s for high-wattage vaping. While not the longest lasting of the bunch (quite the contrary), if you are in the market for powerful 21700s you should get some 30Ts. The only cells that can reliably go up to 100 watts per battery, 30Ts are also ideal for 21700-compatible mech mods.

Samsung 40T

Samsung 40T

The Samsung 40T comes with a name you can trust. Best paired with a regulated single or dual-battery mod and good for up to 75 watts per cell, 40Ts will give you an all-day running time while performing at a consistent level throughout. If you are not vaping at very high wattages, this is the cell to get.

Golisi S35

Golisi S35

The Golisi S35 cell is overrated on the wrap but still is one of the best 21700s currently available. It is capable of a similar output to the Samsung 40T but is not as long-lasting. This is a balanced cell for vaping up to 90 watts, that’s best paired with a regulated mod in single or dual-battery configuration.

IMREN 21700

Imren (gold)

The gold Imren is a solid performer, and an excellent choice for vaping up to 60 watts per cell. Not quite as long-running (or even as powerful) as the Samsung 40T, it makes up for it with its low-price tag. Make sure to follow the “max continuous recharge” rating instead of the 40A that’s written on the wrapper.

iJoy 21700

IJOY

IJOY’s 21700 cell is offered at a very attractive price. While the rating on the wrap is unrealistic, it performs at a similar level to most of the batteries on this list (excluding Samsung). Coming with a price of just under $10, the IJOY is recommended for up to 70 watts per cell with regulated box mods.

How we picked the batteries

Choosing “best batteries” is not something to pick simply based on subjective likes. While our international team of experts and vape enthusiasts use the batteries on our lists, our recommendations and product selection could not have taken place without first going over the data offered by Battery Mooch.

Battery Mooch (or just Mooch) is the vape community’s expert tester of batteries. For a few years now, he’s been supplying the community with in-depth and reliable testing for the majority of batteries used in vaping.

This is not his list of best batteries, though all these batteries have been verified by his battery charts to be worthy of inclusion. Mooch and his highly detailed research can be found on his E-cigarette Forum blog, his channel on YouTube, and his recommendations on Reddit.
