Chimney...you are too cool! Thanks for your help on both subjects!
Getting back to the "high drain IMR batteries." The mAH on these batteries max out at 2250. Other L-ion batteries go as high as 5000. I assume the 5000 will provide a much longer charge. What is the purpose of the IMR batteries in a Provari?
Can I just use the 5000 mAH l-ion batteries in a Provari which I currently use in my Vamo3?
Going by the high mAh ratings that you said your batteries have (5000?), those are likely
"protected Li-ION" batteries. These are volatile chemistry batteries, meaning when they become stressed under load they can get hot, therefore they require protective circuits built into the battery. These batteries, if they were unprotected, could explode if hard-shorted or stressed beyond their tolerance.
IMR, or high drain, or safe-chemistry Li-MN batteries are what Provape recommends for the Provari. Being safer chemistry means they are not as volatile as the Li-ION batteries, and do not require built-in protection. They will not explode if stressed, but may still over heat if stressed beyond their tolerance, and vent hot gasses in an event called thermal runaway.
http://www.e-cigarette-forum.com/fo...-battery-failure-imr-18650-a.html#post3265928 IMR batteries generally have a lower mAh rating than protected batteries, but are capable of high drain bursts of energy required by boost circuits in regulated mods.
Mechanical mods have little or no protection against a hard-shorted battery, so the protected Li-ION batteries are often used with them. Using a Vape Safe Mod Fuse offers an additional layer of security against a hard-short battery.

Regulated APVs like the Provari have boost circuits in the microprocessor which allow higher voltage to be produced. To be able to do this, it requires a high drain type of battery, which the Li-MN or high drain IMRs are. Also, the microprocessor has built-in protection against atomizer and battery shorts - it will either refuse to fire the atty and give an error message on the LED display, or shut itself down completely to protect the atty, the mod, or the user from harm.
Provape designed the Provari around the red AW IMR button top batteries, and recommends only those. Button top variety to prevent accidentally installing the battery in the wrong way which can cause a hard-short in itself. Attempting to use earth magnets on flat top batteries in the Provari is expressively discouraged and will void the warranty.
