The MVA limits in my tables are not to be used as vaping ratings!
They are meant only to give you an idea of the risk if a battery is accidentally discharged at beyond its continuous current rating when vaping. You should not consider them as a rating for the battery that you can vape at!
If properly used the MVA limit can help increase our safety. But it has been misused by too many.
Safety is important and must guide us in the recommendations we make. I have decided to remove the MVA limit numbers from my tables and ask that everyone delete any tables they have now and download the new ones that are available. See the links below.
Please do not post or distribute any earlier version of these tables.
Please delete any earlier version of these tables you might have posted.
Please do not recommend the MVA limit as an acceptable vaping level.
I ask this with all the sincerity and urgency that I can muster...please.
Our community is under increased scrutiny and battery and vaping hardware (atomizer and device) regulations/standards are now being discussed and written...very severe ones. I am not allowed to discuss some of what I've learned but it could be bad. We must set a good example and self-regulate our community as best as we can. I cannot emphasize too strongly the importance of this.
I realize that many are vaping at discharge levels considerably above the continuous discharge rating (CDR) of their batteries and have done so without incident. But that doesn't mean it's done without risk.
Giving the community the tools and data we need to pick the best battery is very important to me though. I have a way to replace the pulse testing I do now. These new tests can be used to directly compare how hard one battery hits versus another and which is the better performer. It will simplify my testing too.
Many battery wrapping companies sell batteries with ratings that are considerably higher than the battery's true ratings. This is an issue I will continue to devote a lot of my time to.
I realize that many of you will be upset at these changes. I'm not doing this to piss off the high power vapers. You will still have the tools you need to pick the best performing battery. I will post about this soon.
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.
Each of us can decide the level of risk we wish to take ourselves but we should recommend safe battery use to others.
Thank you for your time.
Sorry for the long read and the inconvenience of having to replace your tables!
