18650 Battery Ratings and Performance Table

Ladies and gentlemen! Drum roll... please!

Oh, yay! Thanks Mooch. I link people to your cell tests all the time, but the *kind* of people I link to your cell tests are all "cell tests? What's a cell test? Or a cell, come to that?" This should make Mushroom Cloud Avoidance Patrol easier duty.

Good point @suprtrkr!
I'll change some wording, thanks!

Great post! But how long was your test fire?

@VNeil, these grades are all based on the continuous-current discharges done for my tests.
They can be used for pulsed-current safety grading too because if a regulated mod ever autofires, or a mech mod ever has a stuck or accidently pressed button, the current flow will be continuous.

@Mooch I get that it was continuous firing, but for how long? Thirty seconds? A minute? Ten minutes? Until the battery exhausted? Curious minds want to know.

Continuous, left on all the way down to the 2.8V cutoff.
You can see that in the discharge graphs as a smooth, uninterrupted plot line from the start to the finish. For anything less than on-all-the-time-until-the-battery-is-dead I won't refer to it as continuous. I would call it pulsed. Though, in my line of work, pulsed usually means no longer than a few milliseconds.

Thanks. When you say continuous you mean continuous

This is some seriously super amazing information especially for noobs like me. great effort.

So I'm getting an IPV3 LI which specs it's max output at 45A! So is there any battery I can safely use? Should I get the LG HB6 and hope for the best?

I had originally been on the fence between the 25R and the 30Q but from that chart neither would be suitable for the IPV3 LI.

Am I looking at this information correctly?

You definitely don't need 45A batteries.
That mod has two batteries in series and puts out 165W max. Assuming a worst case of 3.2V per battery, that's 6.4V. At 165W you only need 165W / 6.4V = 25.8A max from each battery.

You can use the VTC4 if you want, especially if you won't be running at full power. Otherwise the HB6 will run cooler but you'll be charging more often. I think the VTC4 will work ok for you.

Oops..there is a 200W upgrade, needing about 31A if you run it that high? Will you be vaping at these high power levels? If above 170W then get the HB6's.

That's an extraordinarily high power level though.

Where did you see that 45A specification?

I am waiting for his answer too, but I'll bet that spec came from the manufacturer lawyers to keep their yardarms clear. Honestly, they're gonna get somebody killed by sending them on a hunt for batteries that don't exist to limit their own liability.

Tjanks for the info!

I probably won't run at the full 200w but I saw the spec here under the product description:

IPV3 Li V2 165W Box Mod - Kidney Puncher

But it also recommended the Samsung 25R as a suitable battery.

Lol, that's crazy. But thanks. If they recommend the Sammy 25Rs, I feel better.

If I vape 1.8-2.2 ohm coils at 3.9 and 4.3 volts respectively, using the calculator is says amps is 1.8 to 2.0. Is this the correct number I'm looking for when buying a battery? What would be the difference if I bought a 15 amp vs. 30 amps?
Edit:I read the manual and it says 5amp Max output. How does this configure into which battery to buy?

The output of the board inside that mod is 45A because it might be putting out 3.67V at up to 165W (165W / 45A = 3.67V). But, the current coming from the batteries will still only be 165W / 6.4V = 25.78A maximum (assuming 6.4V cutoff).

What is the low voltage cutoff fir the IPV3 Li?

@skrymir, let's move this to its own post so everyone can chip in.

@Azulsky, which mod are you using?

Please chime in

Wow I was so busy trying to geek out on all the tests you've posted, I honestly had not seen that you put it all together into this chart!!! #sheepishgrin this is awesome, perfect one-stop-shop place to send all the battery questions to -- thanks for all you do to help keep vaping safe!
