How To: Batteries – Mech Mod Safety

This is not for beginners, or inexperienced vapers!

Vapers just starting out, or not looking to get into anything overly complicated should check out our article on starting vaping, or our article on battery safety in general. Mechanical and hybrid mods can be incredibly dangerous and this fact cannot be stressed enough; they are only for those willing to learn about the safety aspects and only for those willing to take the additional risks associated with using a high powered, unregulated device with no safety features right in and around your face…

Much of this article applies to both mechanical, or ‘mech’ mods and hybrid styled mods. Hybrid styled mods share a lot with mech mods (but are different to true hybrid mods), the main difference being that on a hybrid, the positive post on your atomizer or dripper makes direct physical connection to the battery itself whereas a mech mod still has a traditional 510 connector with a positive pin which can, on some mech mods anyway, be adjusted to suit your atomizer.

Never, ever use a normal tank on a hybrid mod! Hybrid mods can only be used with atomizers with protruding positive pins, preffereably only ever with screw own adjustable pins so you can ensure the out negative never comes in ontact with the top of the battery itself.

Use and Understand Ohm’s law:

Before touching mech mods, hybrids, and preferably even rebuildables, you need to have a solid understanding of Ohm’s law to make sure you’re never putting yourself in danger of pushing your batteries past the point of no return and into the thermal runaway zone. Remember if you’re planning to use a device with no electronic safety features, the only thing keeping you safe is your knowledge and your ability to apply that knowledge. Read about Ohm’s law.

Here is a quick reference from a very helpful site dealing with Ohm’s law:

The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω): V(V) = I(A) × R(Ω)

The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): P(W) = V(V) × I(A)

They also have a calculator you can use before and during your builds.

Don’t Discharge Batteries Too Far:

One of the most common mistakes when people start using mechanical mods is discharging their batteries too far. Because mechanical mods (and hybrid mods) have no battery discharge indicator (like the fancy UI you might have on a regulated mod) it can be difficult to tell if your batteries are getting a little low. Now, your worst case scenario is that you discharge the batter so far that it can no longer be charged, this means you’ll now need to replace the battery and buy a new one entirely. Even if you don’t discharge it this much though, regularly or repeatedly discharging a battery beyond it’s safe limits effects it’s ability to hold a charge in the future. The best way to avoid this is really just trial and error. Because your vaping with raw power from the battery, the performance will vary over the discharge cycle and you’ll get a feel for when the battery is getting low. Get yourself a nice charger with a display (I personally use the Efest LUC Blu 6) that can show you what voltage your batteries are at when you put them on charge. Try to make sure you charge batteries before they fall below around 3.8v to be safe.

Currently located in Sydney, Australia, I have been vaping since 2009 and became active in the e-cigarette industry in late 2015. Since then I’ve had the pleasure of visiting over 700 shops in 6 countries.
