Best vape dual battery box mod

The number of batteries in a box is a compromise between size and battery life. The more batteries there are, the longer it’ll last but the bigger the box will be. Dual battery mods are perfect for vapers who want to get through the day without recharging, but still vape at more than 25 W. It will also satisfy vapers who like powers over 80 W, that a single battery just can’t do.

The trend for big clouds

Dual battery boxes have been gaining in popularity since the appearance of high-powered clearomizers. They’re bigger, which also appeals to vapers who like the comfortable hold of a bigger mod. Fans of these mods probably expect more power, but it’s definitely not the only benefit. Their handling and their battery life are also attractive.

Using two batteries instead of one has a downside. It increases the size and weight of the mod. But it also doubles the battery life and the power available from the mod.

Two batteries mean twice the energy available, i.e. double the battery life, regardless of the type of battery you use. Using two 21700 batteries with 4000 mAh gives the box a capacity of 8000 mAh. That’s enough to last all day, even with high-powered vaping.

Using two batteries also allows mods to deliver much higher power, up to 220 W. These models also open the door to the world of big vapour clouds.

It is better to match your batteries, i.e. to use two batteries of the same type, to put them both in from new, and to use them together from then on. That way, the batteries age in the same way and will deliver equal power in the box.

It’s not a good idea to use different batteries, e.g. an old one and a new one, or batteries with different power ratings. It’s the weaker one that – paradoxically – the electronics will draw more power from, so it might exceed its normal operating limits.

No, there are no specific batteries for dual battery mods. Just be sure to only use batteries in perfect condition, and choose ones made by manufacturers like Sony, LG, Samsung and Panasonic over any from retail brands like Efest, Enercig or Trustfire.

Charging two batteries is a bit trickier than just one, because both need to be charged identically. This is what happens when you use an external charger, which is the best possible solution.

Most dual battery mods can charge the battery inside the mod using a USB cord. Some do this very well, and distribute the charge between the batteries individually, but others charge the set together. The first way is definitely better, which is why we include it in our testing.

Most 18650 batteries on the market can deliver a continuous current of 20 A. This is the equivalent of 75 W, whatever the value of the coil used in an electronic box.

With two batteries, this limit rises to 150 W. Beyond that, the batteries are forced to operate above their limit and may heat up. If this happens, reduce the power or use batteries designed for higher powers.

Are all dual battery boxes the same?

No. There can be big differences between dual battery boxes. Some work with a touch screen, for example, while others are designed to be much lighter than average.
