Caveats? What caveats? The cell is capable of producing 148 watts safely. And the mod is capable of 100 watts max. How is that pushing anything to the limit? And you want people to use 3.20v. But the mod refuses to fire below 3.26v. Why do you want them to use a voltage in their calculations that the mod will not even fire at? That is totally ridiculous!
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.
Just watch Busardo's video on the Geek Vape Aegis. He used a cell that couldn't pull 100 watts safely. I knew when I first watched his video that his Brillipower cell couldn't do it. But you don't complain about Busardo doing things people shouldn't be doing anyway, now do 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.
And what does the mod do with Busardo's underpowered Brillipower? It shuts down just like it is supposed to. That is why we buy mods with all of these protections built in. It keeps dumb people from doing dumb things.
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.
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.
