Battery question

[TrikStari]

Just a quick question. My Birthday is coming up, tomorrow, and I'm getting a new vaporizer setup.

I'm looking at getting a Zephyrus V2, and a Wismec RX200 box mod. Right now, I'm just trying to figure out what batteries to get for the box mod. Their website calls for 18650 batteries, with "discharging current above 25a". Does this mean that 30a 18650 batteries would work, or do I need to get exactly 25a batteries?

I'm looking at getting three of these for the box mod.

I forgot to mention, I am getting the non-programmable RX200, not the fancy pants one.

That's a good battery but you can get them for a better price here and pick up a couple sets. Each pair comes with a free plastic case.

18650 Sony US18650VTC4 2100mAh High Discharge Flat Top - Batteries - Batteries, Chargers, and PowerPax Carriers

And these are also real nice choices for that mod.

18650 Sony US18650VTC5 2600mAh High Discharge Flat Top
18650 Samsung INR18650-25R R5 2500mAh (GREEN) High Discharge FLAT Top
18650 Samsung INR18650-25R R5 2500mAh (GREEN) High Discharge FLAT Top
18650 LG 18650HE2 2500mAh High Discharge Flat Top - Batteries - Batteries, Chargers, and PowerPax Carriers
18650 LG 18650HG2 3000mAh High Discharge Flat Top - Batteries - Batteries, Chargers, and PowerPax Carriers

Also some good information on batteries:

You need a good battery for that mod and Sony's are good batteries as well as the others I recommended. Each will keep you safe if used properly.

If you check out the links I gave you you'll find that very few batteries really test at the advertised rating. Being a regulated device as long as you load the batteries correctly and keep the wrap intact any of the one's listed will be good.

Thanks for the info. I will definitely check all this out, as I am placing my orders tomorrow.

(the timing is good to. Since I just lost the barrel for my Kanger Subtank and am relegated to using this dripper that runs out of juice in just a few puffs lol)

Does it matter that some of those batteries have a max continuous discharge rating under 25 amps?

Your planning on using those batteries on a regulated mod so you should be fine. Most times batteries fail in regulated mods because of the wrap falling apart or the batteries loaded incorrectly.

I know it's a lot of information but you should try to take a look at some of Mooch's test results. I don't know him personally but use his information as a guide. I found this blog post interesting because of how many vendors claim 30A continuous. There are no 18650 batteries with a genuine rating over 30A! | E-Cigarette Forum

I am looking through that. What I'm mainly wondering is, does the 25a or greater measurement listed in the mod specifications simply mean "to reach 200w you need this level of battery"? I've never run a dual coil build, so there's a lot of stuff I need to learn. I'm used to running a single coil on an Eleaf iStick 50w, so the only thing I ever worry about is going below .01 or over 25w (according to a few people here, this particular mod can malfunction if run at the max).

So basically, if I get one of the batteries you suggested, some of which claim 20a (which is under the 25a specified by the manufacturer) as the max continuous discharge, will the battery still function properly, if run under the maximum that that particular mod is capable of? I don't plan on vaping at 200w.

Take what the manufacturer says 'under advisement', do your own calculations and base your choice of battery accordingly.

If you run at a lower wattage, you don't need a battery that will support the full 200W. Whether most people really go to the full 200W under normal circumstances is another question.

For instance, I use a single battery mod, run it at the low end of the wattage, and can use just about any battery on the market (but I still always use a high quality IMR or INR battery for safety). Overall, I draw a piddling 1.6A per my mod's display, well under the maximum of even my worst battery, the Samsung 30Q (which will output 15A safely).

Three 20A batteries (assuming the battery's label is accurate, so check Mooch's data on that) can output a theoretical 180 watts (actually, a bit more). Just to have some margin for safety, inefficiency in the mod, and battery aging, I'd limit that to 120 watts maximum.

Good to know. I was merely confused by the term "max continuous discharge", and then Mooch, and several others, pointing out that when you vape you are actually pulsing the battery instead of actually drawing a continuous discharge.

As long as I can run dual twisted micro-coils I'll be happy.

I've never been comfortable acknowledging that the pulse rating even exists. There's no standard for pulse testing, so whether that's 100 ms or 10 s, you wouldn't know unless you research the tests--if they even make that information available.

It's far safer to never exceed the battery's sustained draw rating. Even there, I always leave a good safety cushion. That's not only because my teeth are very close to this battery, but also because a gently used battery lives a lot longer.

I can sympathize with those feelings. It's even worse when you know almost nothing about electricity. All I know is basically positive to positive, negative to negative, and ground to ground. Anything else is your ....
