Mods With Built-In Batteries - What Are They?

[Shinzon]

I recently used my friends RX200s with 3 18650's in it, he was using the TFV8 tank with .15 ohm coil at 130w, I really liked it. I currently use a Coolfire IV Plus which can only do 70w so obviously I am thinking about upgrading.

Innokin do a Coolfire Ultra which according to the specs can do 150w and 36A. This is where I am getting confused. How can such a small device which based on its size and shape, I would say only uses 1 battery, put out 150w and 36A?

I am willing to get the RX200s and a few Samsung 25R batteries but I much prefer the ease of use of a built-in battery and just a micro usb for charging.

I believe I am correct in saying that the 4000mah battery on the Coolfire Ultra would last longer between charges than the 3 Samsungs in the RX200s as it's the volts that are additive not the mah.

I don't know what to buy!

How is easy: the machine uses LiPo batteries, not LiIon, and the LiPos have the advantage of being able to be manufactured in just about any shape. What you think of as "only one battery" is actually (probably, anyway) "only one battery pack" with two or more cells in it, thereby raising the voltage to a level that can accommodate 150W output in exactly the manner your buddy's RX-200 does. It's just the batteries are smaller as individuals, not as big (or with as much capacity) as the 18650s an RX-series mod uses. I don't have a Coolfire IV Plus, but I'd be surprised if the batteries last longer than a RX-200 at the same wattage output. The mAh capacity does add up, it is the ampacity (maximum discharge current) that does not add in series. I think you are confusing the terms: "amps" means how much current the cell can supply; "mAh" means how much current the cell can supply over a specific time period. The first is a measure of maximum applied power (for however long the power lasts at the rate), the second measures (approximately, for a lot of technical reasons I won't go in to) total power capacity of the cell regardless of discharge rate.

Many people like the ease and convenience of a fixed battery mod. I disagree with all of them, but I don't have to use them. My primary point of disagreement is once the battery has reached the end of its useful life, the mod is trash because you can't replace the cell(s). That's on you, of course; buy whatever kind you like. I don't know if your budget will stretch, but the higher powered DNA boards by Evolv are intended to be used with 3S LiPo packs and they will all charge with a USB port.

I have to agree with @suptrkr once a built in battery is dead, it's dead. I mean yeah they can be replaced but by the time you find the right one and go through all the trouble, it ain't worth it.

It does cost more to have to buy batteries but they can be swapped out and charging, while a second set keeps you going, without being attached to an outlet. Then there's the fact of being able to buy more batteries when those aren't living up to the job anymore.

IMHO and it means nothing, under 200w a built in is fine if you're not a crazy sub-ohming manic, as that's hard on batteries. Anything at/over 200w and you're running low, go with external batteries and should be 3- 18650 minimum or larger cell size.

Honestly though, if you were to go to an 80w mod, you'd be happy I'm sure, unless you just want clouds. I can run a mech at .36 to .4 or a .5 or .6 on a VW at 42 to 50w and be just as satisfied, I'm not cloud chasing anymore though (well sometimes I do, lol).

My view is it's best to stick with mods that have a built in battery at least until you can do a Watts law calculation from memory and understand how that should inflluence battery decisions. Or if you must have something with replacable batteries use only what the manufacturer recommends and make an effort to insure you aren't being sold a misbranded fake. A brother of mine has been vaping all day every day on the same iStick 20 for the past three years and he says it's still lasting though the day.

Buy what suits your style.
Built-in battery mods have their uses and can make life easy for you.
External battery mods are the same. It all really depends on you.

Neither is really better than the other.

what I dont like about built in battery mods is when the battery dies ( totally) you have to throw away a good mod...

Not if you DIY Mods... I've remade many mods in the past.

3 Sammys look like they'll easily last longer than the Ultra. Plus, LiPo mod sellers are known to over estimate the size/Mah of their batts for sales.

Personally, I always use LiPo mods and never had a batt die. Sure they won't last forever, but I'm ready for my next mod before they do.

Welcome and glad you joined.
Might want to weigh the pros and cons.
In General lower ohm coils/higher wattage vaping will:
Heat The Coil Faster
Produce More Vapor, can mute taste (coat mouth/build up)
Drain The Battery Faster
Use E-Juice Faster
Produce A Warmer Tasting Vape
Shorten Coil Life
Shorten Wick Life
May be less healthier - higher temps.
May Produce Spit Back
More PV Maintenance/Issues
More irritation to non vapers (tends create more negative comments regarding cloud production)
More exposure to carcinogens at high temps

In General higher ohm coils/lower wattage (generally MTL) vaping will:
Heat the coil slower, which may produce “less” vapor
Provide A “cooler” tasting vape, can produce more flavor
May use less E-Juice (<$ less money)
Prolong battery life (<$)
Prolong coil life (<$)
Prolong wick life (<$)
Less likely zero spit back
May result in less PV maintenance/Issues
Less irritation to non vapers
Aids stealth vaping
Less exposure to carcinogens at high temps
