There are three main considerations regarding safety to keep in mind when using high drain lithium cells. Ensure your batteries are not damaged or have torn wraps, make sure you have the right cell for your device, and always store your batteries in a case.

Every battery cell has a different “continuous amp rating”. To safely use a battery in a mechanical mod or powerful regulated mod it is important to know the continuous amp rating of your cell.

There are a lot of batteries on the market. We highly recommend only purchasing highly reputable cells from Sony, Panasonic, Samsung or LG.

Choosing a battery

If you are using a regulated device at a lower wattage (under 60W with a single battery, or 120W on a dual battery) we would recommend a Samsung 25R or Samsung 30Q as they have a larger capacity, giving you a better overall battery life.

The Sony VTC4, or Samsung 25R are our personal favourites for mechanical mods or vaping at high wattages on regulated devices (above 60W on a single battery, or above 120W with a dual battery mod). While Regulated devices have advanced protection features to prevent your batteries from getting damaged, batteries other than the VTC4 and Samsung 25R may heat up when used at a high wattage, and this will trigger overheat protection on your vape temporarily preventing it from firing.

When your Battery is Damaged

It’s really important to make sure there is no damage to your battery cell, always check for nicks and tears in the plastic wrap and large dents in the battery. Underneath the battery wrap is the negative of the cell, if this comes into contact with something metallic this can quickly lead to a hard short, which can cause your battery to vent. If you find such damage on your battery cell, you will need to re-wrap the cell, or purchase a new one. If in doubt, contact your local vape shop.

To the left are some examples of damaged batteries that should be rewrapped or disposed of. Keep an eye out for damage like this and consult your local vape shop if you are in doubt.

Please do not throw damaged batteries in the bin, if in doubt, contact your local waste disposal team to properly dispose of your Li-Ion batteries.

Carrying Spare Batteries

Make sure to always carry spare batteries in a non-conductive case, such as these dedicated battery cases. Carrying your spare batteries in your pocket or bag where they may come into contact with conductive metal is dangerous as it may cause your batteries to short circuit or vent.
