I'd imagine the Dart LV is easier? My Heavy Hiter Vape Pen has a 10 second cutoff and im pretty sure 650 milliamps is tiny as fuhhhh comapared to 2 amps. Im no whiz owhen it comes to electricity though.
Does anyone know the output of the dart?

Would it be worth it with a battery that has a 10 second cutoff?
A couple of misunderstands getting cleared up might make it clearer?
First off, the spec of interest here is 650 mA
h. The important part being the lower case H. It stands for "hours". Like adding time changes a
distance (miles) to a
rate (miles per hour), adding time changes mA (a measure of current flow
rate, like gallons per minute might be, in this case Coulombs per second.....) to a
capacity. That battery has, therefore, .650 per second times 60 seconds per minute, times 60 minutes per hour or 2340 Coulombs of electrons stored it can transfer. In case anyone asks.
So, in broad terms it can supply .65 Amps for an hour. 1.3 Amps for half an hour, 2.6 Amps for 15 minutes and so on.
LV DART is about 1.5 Ohms, a measure of resistance of current flow. For any given voltage (pressure) more resistance means lower flow (current) like you'd expect. The formula for this is like knowing distance traveled if you're told the rate of travel and the time. For electricity this is Ohm's law, the relationship between voltage (pressure), current (flow rate) and the resistance involved. In our case, using a typical 3.7 Volts and dividing it by 1.5 we get a current used of 2.5 Amps or so. If you think of the "Ohms number" in terms of units of "Volts per Amp" it might be clearer?
Anyway, take that 650 mAh and divide it by 2500 (the number of mA in 2.5 Amps) and the "mA" parts 'above and below the line' cancel each other out and you're left with .26 h (you know you're on the right track when the units part of the values work out right, in this case we lost current units and are left with only time). A quarter hour. We can expect about 15 minutes total run time from a charge.
Got it? Ready for the test?
As to the ten second time out, yes it can be a PITA which is why D9 took it out of their products after Omicron V1. However, you can pretty easily develop the habit of pulsing it every five or so seconds in use.
Of other interest, typical e-cig batteries have a fair bit of drop (voltage wise) under load. They just tune the loads to tolerate it. DART needs all the power it can get staying under the limits, even the small sag (less than half a Volt typically) from e-cig supplies can effect them. DART will do best on a low loss supply like the TV it was designed to run on with AW brand (highest quality) IMR type (best for this application) batteries. That's why this is the factory battery for the TV supply. As shipped, that supply has an important power advantage over 'all the rest' and that includes Omicron as now shipped.
While other supplies will work OK if you dance around the time out, hottest performance will come from the TV setup, followed by the right version of Omicron using the AW battery, followed by that guy with the factory IMR, followed by the rest. Exception to that would be VV heads which can compensate for the voltage drop (by pulling more power from the battery of course).
And you thought you were ready for the test......
So yes, it will work. But it can work better in terms of convenience and power with different hardware.
