LiPo Vs 18650 Battery Mods, Which Is Better?


I was asked this question by a reader named Tim. He asks:

“I’m planning on buying a new mod soon. I first wanted to get a dual 18650 box mod, but my buddy keeps insisting I get a mod with an internal battery since I’ll be saving money and won’t have to buy batteries. Should I follow his advice?”

Thanks for contacting me Tim. Well let me lay it down for you right away.

To answer your question on what type of mod you should get, I would suggest you stick with an external battery mod.

Sure, you’ll save money with an internal battery mod, but there are also downsides to them.

My Problems With Internal Battery Mods

I’ll admit, I was a big fan of internal battery mods when they first came out, but my opinion of them changed after I started using them more.

The thing I hate the most about internal batteries in a mod is once they go out, that’s it. You can pretty much throw your mod away. Unless you know how to tinker with mods and change the internal battery, your mod can now pretty much be summed to a paper weight.

Another experience I hate having with these types of mods is once the battery dies, you have to put it down and wait for it to recharge again.

Now if you had a mod that had external batteries you can bypass this problem by having an extra pair of batteries on hand that you can swap in when your other batteries die.

Sure, there are pass-through mods that you can use while vaping, but what if your mod dies and your no where near a charging station? Your basically screwed.

So Tim, go for that external battery mod you were originally set on buying. I just mentioned the bad experiences I had with LiPo battery mods and hopes this helps you out with the whole buying process.


How Often Should I Replace My 18650 Batteries?

How Often Should I replace My 18650 Batteries

Since we were on the topic of how often you should change your vape coils, another reader asked me this interesting question: How often should I replace my 18650 batteries?

This is a good question especially for someone who is just getting into vaping. You will be going through quite a few of these batteries if you want to do this vaping thing for a while.

After some research, I found out the best way for you to determine whether your 18650 batteries need to be replaced is to get yourself a voltmeter or multi-meter. If your battery output is lower than 4 volts, that means your battery are worn out and will not perform at the level they were intended for.

4.2 volts is the output of a new and healthy battery. Keeping batteries that are at that output level will ensure your mods perform properly.

If you don’t have anything to measure your batteries output, then throw out your batteries after 4-6 months. This is the common lifespan of 18650 batteries.

But then again, I don’t know how much you vape so getting the voltmeter is the best way to determine how healthy your batteries are.

Most importantly, make sure you know how to dispose your batteries properly! What I do is whenever I go to Ikea, there’s a place there where you can dispose of old electronics and batteries. Other places to go to are recycling centers and electronic outlets.

How To Choose The Best 18650 Batteries For Vaping

Batteries are something the vape community doesn’t ponder much on. We are all fixated on our mods and tanks, but every smart vaper knows how important a great battery is in getting a great vaping experience.

I myself am not too familiar with 18650 batteries. All this time my rule of thumb when it came to buying batteries was stick with Sony VTC 4’s or 5’s only, and nothing under 30 amps!

Is it the right thing to do? I couldn’t give you a 100% answer. To be honest I’m really not sure.

This led me to do some research on vaping batteries, particularly 18650 lithium batteries for REGULATED mods.

Fortunately I came across this video from Pegasus Vapor Academy. This man has tons of useful vape knowledge in his channel so make sure to check him out.

Yes, the video is quite long so if you don’t have time to go through the whole video, let me break it down for you.

What is the best 18650 battery for vaping?

So to answer the million dollar question everyone asks, “What is the best 18650 battery to buy when it comes to vaping?” The answer to that my fellow vapers is there is no such thing as a “best” battery for vaping!

Sorry for the letdown, but it’s true. There is NO single 18650 battery that is the all in all, pound for pound battery in the vape world.

What you should really be asking yourself when shopping for batteries is this, “What device do I have and how do I vape?” When you know the answers, then you could use this as a basis on what battery to choose.

Let me explain further.

The only two things you need to know about batteries for vaping

These two things are “amp” (ampere) and “mAh” (milli-Ampere hours). Amps tell how much power the battery can put out, while mAh indicates how long the battery lasts. These are usually indicated on the battery.

Now, here’s the kicker. The HIGHER the amperes on a battery are, the LOWER the mAh and vice versa.

This means the higher your battery output is, the shorter it lasts. This makes sense because you need more power to charge high-wattage devices which leads to draining your battery faster.

How to choose the right 18650 battery for your device?

Let me give an example on how to choose the right battery for your device using the chart above:

Let’s say you you usually vape at 25 watts on 0.5 resistance. According to the chart, you should use a Type A battery which is a 10 amp/3500 mah.

Before I watched the video, my logic in battery shopping was: Let me get the Type E battery. Its 30 amps, which means its puts out A LOT of power therefore supercharging my vape!

Uhm no, that is not the case at all when it comes to understanding batteries. That 30amp battery you use vaping at 25-30 watts is USELESS. Whatever your ampere is in battery, it will consistently fire at whatever wattage you set it to.

If you have a mod that only goes up to 30 watts max, then it doesn’t make sense to use a 30 amp battery when your mod can only use 10 amp.

You want a low ampere battery to make use of the high capacity mAh. This means your battery life will last longer since the battery uses just enough juice to power your device.

Warning: this chart does not apply to mechanical mods. It’s really hard to tell with mech mods because it all really depends on how your build is, but to be on the safe side only use high amp batteries with mechanical mods.

I hope this video shed some light on understanding 18650 batteries better because it sure did for me.
