Hehe, I wouldn't go that far. But seriously, one of the really nice things about electricty is that when you limit yourself to purely DC systems, all you need is a 3rd grade education in math to understand 90% of it. Now it does get into E=MC squared territory when you get into things like the physics of electromagnetic fields and solid state electronics, but for purely DC applications, where the far-out stuff does not apply (like e-cigs), it's all quite elementary.

Hmmm I think for that to work the juice would have to be going light speed while you weren't. When are you going to post that wiring diagram?
You just need to attach a proton accelerator to the end of your mod. Of course this may also solve all of the battery charging problems.Hmmm I think for that to work the juice would have to be going light speed while you weren't. When are you going to post that wiring diagram?
Hmmm... cold fusion vaping?????
Future-proofing vaping for decades to come huh? At least nobody has called me on my "ink pen sized proton accelerator" patent yet...Shhh don't tell anyone...
I am in the same boat as many in regards to mods and battery testing issues but as intended, some of the "worst case" battery issues caused me to order a DMM in preparation for my first true mod, a Precise P-18.
Perhaps I have read too much but my primary interests are mainly safety checks. Some of the online "tutorials" for checking say the 18650's, seem to indicate a need for testing under load via running a resistor in parallel with the test leads.
To keep it as simple as possible, is that type of battery testing just mentioned providing any more information or better information? Or is simply checking the voltage for over/under charging sufficient for our e-cig mod battery testing as to safety of the battery being tested?
Thanks!

The best way to test under load would be by making an adapter similar to the second video I linked to. This will allow you to check the load voltage of the atty or cartomizer you are using giving you an exact measurement of what you are hitting the battery with.
Checking the battery before using it should tell you if there is anything going on with it. I also check mine when they are "dead" to see what voltage they dropped to after use. Just keeping an eye on how they are preforming periodically will hopefully alert you to any potential issues before they become serious.
As an example in one of my mods using 2 14500's in series, Checking the voltage of the batteries once they need to be charged shows me that one battery always reads 0V telling me that the batteries are not draining evenly and the protection circuit is kicking in and shutting off the battery to prevent under-voltage. I need to find a way to remedy this but I think I will need to recharge the batteries prior to them cutting out. I will probably figure out what the usable vape time is and just make sure I switch out the batteries an hour earlier so the batt isn't completely drained. This will also prolong the usable life of the batteries.
I am now seeing one of the benefits of the buck/boost circuit so that you only need to use one battery.
I will let someone with more knowledge than me describe what to look for when measuring the voltages so that I don't give you mis information as I am still on a learning curve myself. =]

Thanks very much for your feedback. It does help me in knowing a bit better what to look for as it applies to our mods.
Yea just remember don't cross the streams of unlicensed proton accelerators
And for those who ask what happens when you cross the streams...the marshmallow man goes everywhere...lol
srry couldn't help it you put a particle accelerator in a PV...
