You may need to go with a tube mod, like the SmokTech Bolt or something. 3.7v at 1.5 ohms will net you only around 9 watts though. Here's an example

The BOLT ECIG by SMOKTech

For variable voltage, you are stepping up in price but have more flexibility in your desired vape. The LavaTube would be an example of a VV tube mod. With that you could turn up the voltage.. to say 4 volts and get you a good 11 watts with regulated power.

Buy Lava Tube | Get Lava Tubes | Find LavaTubes Carry Case and Accessories

Basically whatever you can fit a AW IMR battery into. I don't think the stick eGo type batteries were made for vaping at 10+ watts. They would be the cheapest entry, and a VV eGo like the Twist or the Vision Spinner could get you your 4+ volts, but will they die like your last battery? Maybe so.

There exist knock-offs and derivatives of the Bolt and LavaTube that may run cheaper. Tube mods are nice because when the batteries die they are replaceable, without replacing the whole mod, which will save you $$ down the road.

Maybe someone else can chime in with ideas/opinions

What do you have that you'd tried 10-11 watts on the carto? You need to be around 4V to get there, I'm guessing you may think you're at 10-11 watts, but really aren't. It seems most PV's aren't really putting out the voltage they claim when they're getting into the higher power range.

It was my old ego clone Riva that supposedly puts out 4.2 freshly charged.

But thanks guys for the suggestions! I'll look into the bolt.

Also, is the bolt regulated? Or will the power die down as the battery gets low?

As far as I know, the Bolt is not regulated. I don't think there's is any extra circuitry. It's a pretty simple straight-forward mod. That VAMO that rik701 posted looks cool. Variable wattage is nice for consistency across different delivery devices.

    This is the best low price mod for that LR DCC ($35)

    When you have a dual coil you have to double the normal voltage to get the same wattage as you did with a single coil. If you use 8 watts on a 1.5 ohm total coil resistance you will have two coils at 3 ohms each and need almost 7 volts to get that 8 watts on each coil and the amperage would be 4.7 amps. Pretty high for most mods. If you went to 6 watts then you would only need 6 volts but the amperage would still be high at 4 amps. Still pretty high current. Some batteries will not handle that. Dual coils are tough on battery use time and wear and tear. The formula is sqrt(desired watts *ohms)*2 for a dual coil to get the voltage needed.

    Wrong Answer

    Watts = Voltage * Current no matter how it travels 1.5 ohms is 1.5 ohms no matter if it's made with a single coil, a double or seven coils.

    Actually in the real world you're both wrong.

    With parallel coils the total wattage provided by the PV is in fact cut in half for each coil. However, if you use a DCC at the same wattage to each coil that you would use to one coil of the same resistance (16 watts to get 8 watts to each coil), it's quite likely that you would have smoke comming out of your ears. So in practical use, the reality is about half way between, and the DCC performs best in the 10-12 watt range (5-6 watts to each coil)

    So in other words you're saying is ...
