MVP2- Does coil resistance matter?

[jjuice]

With the MVP2 does the resistance of the coils make much difference if you are using it in wattage made? If it does, what resistance do you prefer and why?
Thanks!

You can reach the amperage limits of the MVP2 quite quickly, going low ohms, or high ohms.

I find roughly a 2 ohm +/- .2 ohms is ideal for the MVP.

I have put a 3 ohm coil on mine, and when hitting it with full power with the MVP, and comparing it to hitting the same topper at the same power on a dna 20 device, the MVP is noticeably weaker even though it is claiming to be putting out the same power level.

Although the MVP is a variable wattage battery, the selected wattage must fall within the voltage range and maximum current draw of the battery.

These limits are 3.3 volts minimum, 5.0 volts maximum and a maximum current of 3.5 amps. When the MVP is in variable wattage mode, it will sense your ohms and attempt to fire the requested power as long as the above minimums and maximums are not reached.

For a 3 ohm coil, the MVP2 would only reach a max of 8.5 watts since anything set higher than 8.5 watts would cause the battery to would simply keep firing at 5 volts.

For a 1.5 ohm coil set to 6.5 watts, the MVP2 would lower itself to the minimum of 3.3 volts to the coil which means that it would actually send 7.26 watts to the coil

Setting the battery to vv mode allows you to directly control the output of the battery thus allowing power to be adjusted to values that are outside the adjustable wattage setpoints.

For example, if you put a 1.8 ohm coil on it and adjusted the VV setting to 4.9 volts, You could actually push 13.3 watts to the coil even though in VW mode you could only set it to 11.0

Conversely, if you put a 2.5 ohm coil and only set VV to 3.3 volts, you would only send 4.3 watts to the coil, even though the minimum wattage setting you can select in VW mode is 6 watts.

Go with what taste best and vapes best. I prefer my standard ohm builds to be 1.5-2 ohms. gives me more leeway on my amp limitation on my regulated device. Ultimately, it comes down to the atomizer and what it can handle and your personal preference.

The lower ohm resistance, the more current you will draw and the shorter battery life.
The higher ohm resistance the less current you draw, but the MVP must adjust to a higher voltage.

The battery is capable of 3.3 to 5.0 volts.
The amp rating is 3.5 amps.

Your power setting must fall within these limits.

For example with a 3 ohm coil, you will only be able to push out about 8.5 watts before you reach the voltage limit of the battery.

Similarly with a lower resistance coil, you will likely over draw your watt setting. For example a 1.5 ohm coil at 6.5 watts would require the battery voltage to be 3.1 volts. The MVP would fire that at it's lowest available voltage of 3.3 and thus you would draw more than 6.5 watts.

It's best to keep your resistance in the 1.8 to 2.5 range.

Thanks for the reply. Opus rocks!

I like 3ohm cartos, but the MVP has a 5volt max output. 2ohms will give you the best range for it. If you're not going to go at or above 9watts (5.2volts with 3ohm coil), I personally would choose 3ohm cartos.

Edit-and the mvp2 will fire a 0.8 ohm coil, but you won't be able to adjust anything. It will only fire ~2.8volts.
