I will likely pick up a couple VTC5As to have available should I be trying some lower resistance builds. And I suppose I could do my own general test to see which last longer. If the difference in the amount of run time or actual hits on the device isn't extreme it shouldn't be an issue. I mean if we're talking 10-15 pulls on the device that's not much difference really. I guess the main difference is the price at this point. But the price for only a couple batteries to have the option to use lower resistance builds would be worth it IMO.
Just out of curiosity what would most regulated mods do if the power rating was exceeded? Not that I would ever vape that high but let's just say I was using two HG2's at 200W. Would the batteries get warm? Would the mod just give an error and not fire? Would there be the possibility of the batteries venting?
Remember the resistance doesn't matter with a regulated mod like we said before- build at 0.1 or 1 Ohm, run it at 100W, and the amp load will be exactly the same on your batteries , so don't choose batteries based on your resistance with a regulated mod, only the power you intend to run them at.
I would also choose based on price, and how far you are going to push things power wise an choose a battery with a suitable CDR. Usually something like the 25R or HE4 is available at a great price, then the HG2 and 30Q's are also good value. Capacity is also a bonus if you aren't pushing insane power levels.
The Sony's are fantastic but usually slightly more expensive, but not by much so may be worth it.
It is a lot more than 10-15 pulls from what I have found with my regulated mods, it is the difference between the mod lasting me either until evening or the whole day.
If you exceeded the CDR by a large amount, the best thing that could happen is the voltage sags so much you will get a weak battery message. Worst case you have a bomb in your hand. So always best to stay within their limits.
If it is by a little, it will likely work, but you are stressing the batteries past their design, which is not good.
