I am still confused here. The thing about not taping the button down is exactly what we are speaking about isn't it?
Thats exactly what a pulse is. So if you pulse your mod, surely you go by a pulse rating?
Actually, you never, ever, ever go by the pulse rating. There is no defined value for a pulse. One second? Two seconds? 10 seconds? It could be anything. The user defines the pulse of the battery by the resistance of the coil. In other words, it will pulse at whatever you tell it to pulse at.
It is up to you to know how long the pulse is going to be, how fast the battery heats up when pulsed, the chemical make up of the battery.. Eg, will it pop if pulsed at X amps for Y seconds. To know how low a resistance can be used before the battery goes into a thermal run. How long you are going to be firing at XAmps and how fast the battery will heat up at XAmps.
Now, about taping the button.. Don't think that just because you are within the CDR that you are safe. A battery heats up when you pass current through it. CDR or no CDR, it is still heating up. So you can fire a 20A CDR battery at 18 amps, or 20 amps or 22 amps, and it still heats up. What you need to know is, how long it takes and how hot it will get. There is an actual graph in Mooches Blog about this. But anyway, lets use this example, and these numbers are ONLY for example.. 20A CDR. discharged at 20 Amps, might take 5 minutes to fully discharge and reach a temperature of 70F. Discharged at 18 Amps, might take 5 minutes and 30 seconds and reach a temperature of 68F, and Discharged at 22 Amps, might take 4 minutes 30 seconds and reach a temp of 72F. The problem comes, when you discharge the 20A battery at a rate that brings it up over 100F before it completely discharges. And there is why we don't use a pulse rating. How fast does a 20A battery, Discharged at 35A (pulse rating) take to heat up past 100F or will it discharge fully before reaching 100F. 100F is the safety cap Mooch uses for his testing. And of course, the hotter a battery gets, the faster it heats up. The problem comes, when you pulse a battery at such a high rate that it heats up faster than you can react and it heats to over 100F.
Now lets say you are some vape fiend and vape 1 puff every 10 seconds for 60 seconds. Is it safe to do this at 20A on a 20A CDR battery? NO. Is it reasonably safe? Yes. Is it safe to do this at 18 amps on a 20 amp CDR.. NO.. Is it reasonably safe? Yes. Is it safe to do it at 22 amps on a 20 amp CDR, NO.. is it resonably safe.. YES. Why? Because at all 3 levels, the battery temperature will never exceed 100F. So here is the big thing, if your fire button sticks, How long does it take at 18, 20, 22 amps to either drain out the battery or heat it past 100F where it runs the risk of venting? The other factor, is the chemistry of the battery.. does the chemistry allow the battery to heat faster than the venting gas can be dissipated? In a cheap battery, the answer is yes, and the battery pops, just like a balloon. In a good, high quality battery, such as Sony, Samsung and LG that we all recommend, the answer is no. Gas is vented before it can build enough pressure to go POP.
Now I will not tell anyone what is 100% safe for them to build at. That doesn't exist. Anyone that thinks it does is a fool. What I can say, is that if you have a 20A battery, and it is running at 22A then it is still reasonably safe. In other words, it won't vent or blow up under normal conditions. Remember here, I did not TELL you to run it at 22A, I said you COULD run it at 22A and still be within a reasonable safety margin.
Now as to the What IFs.. it is the users responsibility to avoid the What ifs. What if.. the end of your coil stuck to the post and you didnt notice.. and dropped down across the insulator? You avoid this by knowing where the clipped ends are and making sure they aren't inside your deck.
What if.. you fall asleep on the couch with your mod in your pocket.. you avoid this by not sitting on the couch with your mod in your pocket. The more risks you take, the more risk you are at.
What people need to understand, is there is no mechanical mods made by Fisher Price. These are not toys. These are advanced vaping items. There is a risk to using them. And YOU are responsible to limit those risks.
While learning, it is fine to ask questions. IS it safe to run at 22 amps on a 20A battery? NO.. Is it reasonabley safe, Yes. Is it safe to run at 20A on a 20A battery.. NO.. is it reasonably safe.. Yes.
How high can I go safely on a 20A battery.. You Can't. How high can I go and be reasonably safe.. GOOGLE IT or read Moochs blog and find out.
Sorry Zutankhamun, I went a little deeper than why we don't use pulse ratings.
