Ohm's Law for vaping
Mechanical or Unregulated (Voltage/Resistance=Amps (voltage is fresh charge so 4.2v))
Regulated Mod (Watts/Lowest Battery Voltage/Mod Efficiency=Amps (most mods cut off 3.2vper battery, mod efficiency can be between 85% to 95%, so divide by 0.9 to get a ballpark)


The mod goes up to 100W with the firmware upgrade so that makes it (100/3.2/0.9 = 34.7A)

Well that should answer why 25A would be more then enough before you even ask OP. The ones that say something crazy like 80A were tested to be 25A. Just don't get eFest(from what I've read)... AWT 4500mAh 75A I heard was the best. From Mooch,
Basen Black 4500mAh
Brillipower Green 80A 4500mAh
Efest Green 20A 4200mAh
Efest Purple 40A 4200mAh (Not recommended yet due to the one dud cell)
MNKE Orange 35A 3500mAh (NOT RECOMMENDED, due to all the fakes being sold)
That's just a CDR. Worst case if it malfunctions and fires on its own your still safe. The battery will just die not explode.



It's looking like there is no such thing as a 100W mod powered by a single 26650. It's all just a web of lies. :nah:

No firmware update for it? I see 100w too. He just used bad wording with no explanation that's all. Made it sound like your mod won't work or something lol. People run 75w on a 20A battery all day. I go by CDR but you can pulse probably 35A, check your batteries pulse tests by mooch, the lowest is the safest obviously. ex my 20A CDR rated 30A at 6 secs on 12 secs off or 35A I believe at 5 secs. Always best to be safe though.

There is no single battery capable of supporting 100w if saftey is one of your concerns.
All the built in protection features will not protect the user if they install & use an insufficient CDR battery.
Pulse/rapid/burst/quick discharge ratings are worthless --->
Battery pulse ratings are useless! | E-Cigarette Forum

I'd bet the power device will fire the advertised 80w ~100W in a very narrow & specific Ω range that doesn't exceed the amp limit of the power device.

Again resistance is irreverent when calculating battery amp drain when using a regulated power device.
---> Calculating battery current draw for a regulated mod | E-Cigarette Forum


High watt devices sell like hotcakes to folks that have no clue about battery saftey and what can happen.
Luckily most folks rarely if ever use much more than 1/2 the output power the device can produce.

"Battery pulse ratings are useless" is based on the ratings given without information like how long they were pulsed. This is a reference to the 80A batteries, that "rating" is probably 0.5-1 sec. From the post itself if you read it. "So how should you choose a battery to get both the most power for your mod and still be safe? Either go by the continuous discharge rating (CDR) or find a reviewer that tests batteries beyond the CDR and records temperatures to know when it becomes unsafe. But for longer battery life, consider running your batteries below their CDR. It adds a greater safety margin as the batteries age and lets them run cooler." Mooch does these tests on most batteries himself. Just look up the battery you are using. I'm paranoid level safe myself but many people do it. Need to monitor your batteries full charge level Volts and replace them way more often too. See the Wismec Presa is 100w 26650 too lol...crazy companies making mods that will explode if you use them cause no such battery exists.lol

I thought @Gramdogg last post was quite helpful. You raised a good point, we've discussed it.
Trying to fit a square peg into a round hole is a constant challenge with e-cig hardware and batteries.
Makers of both over-exaggerate.

I'm still cross I bought a car that claims to do 74mpg and no matter how I drive I can't get more than 59.9. :)

You're right. I misinterpreted his post and spat the soother. Sorry about that.

I like the idea that the Wismec Presa is called a "express kit" and not a "starter kit" like the Pico Mega. If there is actually one good thing the FDA could do it would be to change the names of what classifications are needed to be called a starter kit when no advanced or beginner kits exist. EVOD kit and this crazy thing are both "starter kits"? lol

Better explanation from Mooch. CDR=Good safety margin, MVA(max vaping amps)= bit of safety margin incase of malfunction, Above MVA= less and less safe, higher risk of venting. I use Samsung 25R5 20-22A CDR depending on reviewer and 30A MVA by Mooch. My mod max is 75W or 26A after 10% margin BUT it will say "weak battery" after about 20 puffs at 75W so I wouldn't want to go over 50-60W without a 30A CDR anyways or I'd be changing batteries every 20 mins. If your going to be away from your mod put it to CDR or below or remove battery/tank incase of malfunction. If your near by you should be able to hear it if it malfunctions and starts working on it's own... juice snap, crackle and popping.
