Exceeding the CDR tends to stress the battery. Stressing the battery damages it and lowers its performance potential for future use. Once you've pulled excessive power from a battery, you no longer know what it's capable of doing.

3.2 v is the standard figure for that calculation because it's at or slightly below the limits for most mods and saves you the trouble of finding out what the limit for that particular mod is. As you say the limit for the Aegis is 3.26 v, I agree that it would be perfectly reasonable to use 3.26 v instead of 3.2 v. The difference is two watts - 88 w, rather than the 86 w I initially calculated.

Look name one cell that will fit in the Aegis (18650, 20700, 21700 or 26650) that could safely pull 100 watts at 3.2v or even 3.3v? Guess what? There is no such animal (unless it is a LiFe cell). You would have to pull 30A at 3.3v just to almost get 100 watts and the battery sag will be so great at that low voltage the chips won't even work. The battery voltages we have talked about is at rest. So using your own standards, no cell on this planet (except LiFe) could be safely used in the Aegis. And if you did use a LiFe cell (they are very expensive), you could only use about 30% of the capacity before the voltage would drop below 3.26v and the mod would refuse to work.

Yet Geek Vape recommends the Golisi IMR 26650 35A 4300mAh cell. And Mooch claims that the Aspire 26650 has the same specs. And then I say you can safely use the Aspire 26650 in your Aegis and you want to argue with me that isn't safe. Do you want to argue with Mooch and Geek Vape too? So who is misleading users here? Is it Geek Vape, Mooch, and me or is it you?

I'm not the internet police. I don't complain about what Busardo's doing because I don't happen to be interested in watching videos. I am interested in reading ECF. When I encounter something it seems appropriate to comment on, I do so.

As I said, I haven't watched the video. If you'd like to give me the timestamp I'll check it out, but I'm not spending an hour on a video I'm not interested in just to find it. That said, given what I know of regulated mods and their safety features and the way batteries work, I doubt the mod shut down. I expect the battery failed - if you try to draw far too much current from a battery the voltage collapses and nothing happens.

Oh for Pete's sake! You remind me of someone who complains about a book who never actually read the book. Okay for all of the cry babies out there, here you go. Busardo claims he could only get 85 watts out of the Brillipower cell. Busardo is one brave soul. As I would never push a Brillipower 26650 at 85 watts ever! Notice that the wrap says 80A? Those damn liars, it can't even do 30A (and claiming that it does better than 20A is really pushing it). But at least the Aegis was smart enough to not let him push it further.



I think you're saying here that you believe regulated mods have safety protections that prevent excessive draw on a battery (excessive being something that would damage it, cause venting or trigger thermal runaway). If I've misunderstood you, please correct me. If not, you're mistaken. A regulated mod will not prevent you from damaging, venting or blowing up a battery. They do have one feature that reduces risk somewhat, but its effectiveness is limited.

The only feature that limits what you can do with a battery is the board temperature sensor/shutdown. If your battery is overheating it will eventually heat up the board which will then shut down and stop pulling power from the battery. The problem is that the battery might already have entered an irreversible process leading to venting or thermal runaway well before the board gets overheated and shuts down. It's a good safety feature and may prevent some problems, but it's nowhere near foolproof.

Apart from that, mods have no idea what battery is being used and no way to tell whether that usage is appropriate or not.

Wow! You have a lot to learn yet. Okay I will start really simple. Say I take a flashlight/torch cell that can only do 5 watts and throw it into an Aegis. What will happen? Probably nothing at 5 watts or less. Now ask it to do 100 watts. Now what will happen? The voltage sag will be huge and the Aegis mod will simply shutdown.

I'm very well aware that there are no batteries that will safely provide 100 watts at 3.2 v. It's a serious and well-known problem with the way mods are marketed. If a single battery mod says it works up to 100 w, what they're saying is that the board can handle 100 w. That doesn't mean that any battery exists that can safely provide it.

Yet Geek Vape recommends the Golisi IMR 26650 35A 4300mAh cell. And Mooch claims that the Aspire 26650 has the same specs. And then I say you can safely use the Aspire 26650 in your Aegis and you want to argue with me that isn't safe. Do you want to argue with Mooch and Geek Vape too? So who is misleading users here? Is it Geek Vape, Mooch, and me or is it you?

It would seem that you're drawing a faulty conclusion from what Geek Vape and Aspire have said. As for @Mooch, he has never claimed that 'you can safely use the Aspire 26650 in your Aegis to 100 w'. The calculation I used earlier is from Mooch:

Calculating battery current draw for a regulated mod | E-Cigarette Forum

As you can see, Mooch's calculation supports limiting your watts to 88 with that battery.

Here's another quote from Mooch:

"But I can only recommend to our community that we never exceed the continuous current rating (CDR) of any battery. These batteries were never meant to be used outside of a battery pack with suitable protection electronics." (The MVA limits in my tables are not to be used as vaping ratings! | E-Cigarette Forum)

Er, you were the one with a complaint about Busardo. You interpreted what he said to mean that the mod would protect you from misusing a battery. This is not entirely correct. A mod will help with certain types of misuse - in this case the voltage sag likely triggered the low battery warning - but it will not protect against all battery abuse. You can still use a battery very unsafely (and risk venting or, in the rarest cases, thermal runaway) in a regulated mod.

Wow! You have a lot to learn yet. Okay I will start really simple. Say I take a flashlight/torch cell that can only do 5 watts and throw it into an Aegis. What will happen? Probably nothing at 5 watts or less. Now ask it to do 100 watts. Now what will happen? The voltage sag will be huge and the Aegis mod will simply shutdown.

When you demand 30 A from a 500 mA battery and nothing happens, the mod has not done anything to protect you. It tried to fire. The battery's voltage then collapsed, so it provided no power to the mod to do anything.

I've been using both iJoy 26650 and their 21700 batteries without issues. They both last half a day, if I'm not at work. I vape consrantco at home...

Btw, my Aegis is 7 months old, been dropped onto travel and ceramic flooring once each (accidentally), and still looks and performs like the day I got it. Mines fully updated. No issues.
I have a second one, never used, just in case.
