General Battery Safety

Do not store or transport external batteries (18650, 20700 etc) without using a case. Carrying loose external batteries in your pocket or purse poses a major safety hazard, as it is possible that the positive and negative terminals of the batteries may be shorted by keys or other metallic objects. Shorted batteries will catch fire or explode.

Never leave batteries charging unattended. Do not charge when you go to sleep or leave the house. There is a risk of fire with any lithium battery due to the nature of their chemistry.

If a battery is showing any signs or damage, has been dropped or crushed, do not use it.

It is not safe to use external batteries (18650, 20700 etc) with any signs of damage to the protective casing.

Dual / Triple Mods

In any device that uses multiple batteries it is crucial that the batteries discharge at the same rate, otherwise one battery may be put under a greater load resulting in that battery operating outside of its safe limits. When a battery is overloaded there is a risk of venting, thermal runaway and fire.

The batteries you use in a multi-battery device must be the same make and model, purchased at the same time, and must only be used together (typically referred to as marrying your batteries). Charge all batteries to full capacity before first use.

Though some multi-battery devices can be charged via micro USB, we strongly recommend an external charger. External chargers are much better at balanced charging and are safer and faster. When recharging married batteries you must charge both batteries to full capacity before reuse.

We recommend rotating your batteries between cycles to ensure even wear.

Mechanical Mod Safety Guide

Before using a mechanical mod (or mech mod) there are a few things to take into consideration.

Mechanical mods use lithium-ion batteries, but unlike regulated mods mechanical mods have no safety features (e.g short protection, overcharge protection or overheat protection). Without safety features a lithium battery can be dangerous without the proper precautions. It is crucial you understand these before choosing a mechanical mod, especially for vapers new to using an unregulated device.

Mechanical mods are great to use with the proper understanding. Mechanical mods don't have screens or adjustable settings so you are left with unadulterated power and no complex electronic components, making them generally more reliable, efficient and sturdy than most regulated mods.

Proper Precautions

Only use reputable batteries

The big battery manufacturers are Sony, Panasonic, LG and Samsung. It’s best to get a battery from one of these manufacturers as they are reliable, consistent in quality and have been manufactured specifically for high drain devices like vapes.
Batteries not sold by the aforementioned suppliers are likely rewrapped batteries, and possibly lower quality batches, often with false or misleading limits on them. If the battery information sounds too good to be true, it probably is.

All of the batteries available on our website are authentic and sourced from reputable suppliers.

Only use a battery within safe limits (and know the safe limits of your battery)

All 18650 batteries have a “continuous discharge rating” measured in amps. Do not draw more current (measured in Amps or “A”) than what is rated on your battery or you risk venting or damaging your battery and/or mod. If the battery draws an excessive amount of current for too long it will go into thermal runaway and start venting, potentially catching fire and/or exploding.

Different models of batteries have different ratings, be sure to get one appropriate for what you’re using it for.

Know how to calculate your current

You need to know the current (how many amps) you will be drawing from your battery with a given build to ensure you aren't drawing more current than the battery can safely provide. For this you need an ohm reader or a regulated mod which accurately measures resistance.

To calculate your current use the following rule; current = voltage/resistance.
For example you’ve got a 0.5ohm build on your RDA and you’re using a 4.2V(max voltage) Sony VTC4 18650. Therefore, current (A) = 4.2/0.5. You will be drawing 8.4 amps, well within the 30amp rating a VTC4 battery can safely provide.

Make sure you’re not shorting your battery

If your battery has a hard short you can quickly vent your battery. Check your builds on a regulated mod if you’re unsure of them.

Don't over discharge your batteries

Don't over discharge your batteries, only discharge your batteries down to 3.2 volts. Going lower than this will quickly shorten their life span. You will notice a decrease in power when they get this low. Use a multimeter, regulated mod or advanced battery charger to check the voltage of your batteries.

Do not invert your battery/batteries

The body of your mechanical mod is negative, this means if your battery wrap gets nicked or damaged and the negative of the battery touches it will be less likely to short.

Only use batteries which have undamaged wraps.

If the wrap of your battery is damaged the metal outer of the battery can come into contact with the mod and cause it to short.

Get someone who knows how to re-wrap your battery or dispose of it.
