New Here - MVP 2.0 Question

[leeson]

OK so I have just got my MVP 2.0 on 12/24 and it just now died today (12/27)
I know when you press both buttons it shows the ohms of the coil first right?
the second number it shows is the remaining volts of the battery? I read that fully charged is 4.2 BUT mine had fully died and was reading 3.7 still? maybe I am confused on what this is but I thought it was how much battery is left?
Just if someone could help me out with what these numbers mean, thanks.

Put'er on the charger


I'm on my iPhone

It stops working at 3.7 Volts. Its designed to do that....... as said, put her on the charger now.

 

[leeson]

yes its on the charger it already went to red and then blinked red,
I am still confused on what the 4.2-3.7 means. will this effect anything when vaping at any volts higher then what it reads?

That's a very good question. I'm pretty sure the answer is no but a very good question indeed.

The voltage it shows after the coil resistance is the voltage of the battery. There is a boost circuit in the unit that will allow the output to go up to 5V in the voltage settings. 3.7 volts isn't dead on the MVP. The fire button should glow yellow at 3.7v when you press it. Mine didn't turn red until it got to 3.6 or 3.5 volts. When you plug it in to charge the light will light up to what level the battery is and change as it charges up. I'm not sure what the blinking red is. It should be solid red. Leave it on for a while and it should eventually turn yellow then green then turn off when done.

Just charge it. The battery is just discharged.

If you mean it went to red, then blinking red while you were using it, then the color is just indicating that you will need a charge very soon (red), and it has reached its cutoff point (blinking red).

Your fully charged battery should be around 4.2 when you press both the p and u buttons after it shows resistance. This is saying what the battery is currently at, as if you were to take a DMM and stick it on the positive and negative of the battery. You set your wattage/voltage, and then the circuitry inside changes the voltage to whatever voltage or wattage it is set at. Your variable wattage feature will automatically change voltage for you if you like a certain wattage vape on different resistance atomizers.

The MVP is designed to not work when the battery gets below a certain level, rather then give you less power when you attempt to vape with it. Some batteries will still work when the power is that low, but you'll get a poor quality vape, plus it hurts overall battery life to let it COMPLETELY discharge. So, the MVP and other regulated devices will shut down before that happens.

Use the lights. When it turns yellow, o charge mine then. I never let it ho down to red.

I am still confused on what the 4.2-3.7 means.

A picture is worth 1000 words:

A fully charged battery will be up around 4.1 volts. By the time it gets down to 3.6 volts, it's 85% discharged. Discharging it past about 3.5V or 90% is really bad for battery life, so regulated devices usually won't allow that.

Ok yea that helpsfor sure I better get it now. So the mvp is considered a regulated device? Mine was fully charged at 4.1 and died at 3.7 Ill check again for this 2nd charge.
Well thanks everyone for all the responses, appreciate it.

 

[Rossum]

Yes, it's a regulated device. If you can set the output wattage (or even voltage) it's regulated. Heck, even the cheapest eGo type batteries have a simple circuit in them that prevents them from over-discharging the battery. About the only devices that don't have something like that are the purely mechanical mods.

If you discharge a lithium-ion battery too far, it can be downright dangerous to re-charge it and most chargers will refuse to even try.

The way I do mine is just plug it in every night when i plug in my cell phone. Never went dead on me yet. I am going to order another one of those charger cables though. Love the different attachments and comes in very handy...now only if it had a Ego attachment too...LOL

 

[SnowDog]

I guess they are all a little different. My light has been yellow for about 50 puffs or so. It just changed from 3.7 to 3.6 volts and the light is still yellow.

 

[Rossum]

Here's my guess: The voltage shown is probably the battery's "no-load" voltage. But I bet the electronics in the device also monitor how low the battery's voltage drops when under load when you fire it. You don't see that, and it's partly dependent on the resistance of the load, as well as the condition of the battery itself, but it's an important factor in evaluating the battery's state-of-charge and whether it can continue to fire the load you have on it without an adverse effect on the battery's life.
