To all the VP2 experts. I'm getting ready to leave and play some golf so I usually take my 2.5 for golfing. I did a battery check and the Provari reads 3.6 volts. I put in a fresh battery and placed the 3.6 battery in my VP2 and it read 3.9 volts. What am I missing?

I'm curious about this as well. Yesterday, I put in a battery I had charged in the VP2 and it of course said 4.20, but was read in the P3 as 3.6. Today, the same scenario, but a different battery and it reads 3.9v.

3.6V vs 3.9V is the difference between the battery under load in the ProVari, and being charged in the charger. The charger will always read a little higher due to it being charged, and the ProVari will always read a little lower due to it being read while under load (firing the coil).

As for your huge difference between 4.2V and 3.6V, something is not right. That much voltage drop is either a very old battery ready to be replaced, or under a load larger than the ProVari can provide. I see that much voltage drop in my SXmini at 50W. Maybe 20W would drop it to 3.9V under load - especially if it's a smaller battery like an 18350. The larger the battery (think 26650), the less voltage drop under load.

John,

These are all pretty fresh batteries. In my P3, I don't recall EVER seeing the voltage for the battery exceeding 3.9. But in reality, these are 18490 batteries, which are actually 3.7v, so getting a reading of 3.6 on a P3 shouldn't be that bad or far off from their design spec. What I don't understand is why on the PV2, with the switch on the back set to 3.6v, the batteries all show 4.20v at full charge?

The voltage you're reading on your P3 is the voltage being used to achieve your wattage setting.
P3 only displays battery charge as %

I'm a little confused, where do you see the remaining battery voltage in the P3? I only see %.

I believe that feature is part of the upgrade.

Never mind. I thought the latest P3 upgrade showed the remaining battery charge like the 2.5 or maybe like the Classic, but I was mistaken.

oops.....Never mind........SR had a senior moment in there. Yes he did!

And to demonstrate just how my mind works (or as I have been accused of before - doesn't work), the difference today from yesterday is I'm using my KFL+, which has a higher ohm coil than is in what I had on my P3 yesterday (Russian 91%) which has a lower ohm coil. The constant is they both produce great flavor and vapor at 10 watts. Hence why my P3 is showing 3.9v today as opposed to 3.6v yesterday. Duh.......
