a 2 battery mod going all the way up to 220 watts? That sounds like a recipe for disaster. Even with true 30 amp batteries at a full charge, you are limited to 252 watts(not accounting for any voltage sag...at that high of a drain, you WILL have some voltage sag). The mod is going to have SOME inefficiency. Once the batteries are half drained, you are already at the limit of your batteries if you are trying to run it at 220w. Simply stated, a 220w mod running off only two batteries simply isn't practical. Realistically, with true 30a batteries, you are going to be able to hit it 2-5 times(if that) at 220w before you are actually exceeding the limits of the batteries after the voltage sag.
Personally, since you don't want to learn to build and just want something to throw on there and chuck clouds, I would say just get a tfv4 and ramp it up to 90-120 watts depending on the coil and watch the clouds fly. If you really want to go much higher than 140ish, you are going to have to learn to build your own coils. Even then, with a dual battery mod, I wouldn't even bother going above 160 even with 30a batteries simply because you are going to be running the batteries at their limit the whole time, getting terrible charge life, and the batteries are going to wear out incredibly fast from being run near their limit all the time.
Probably not what you really wanted to hear, but it is the truth.
At 25A duty, even the LG HB6(a true 30a battery) is going to suffer a voltage drop all the way down to a little under 3.6v per cell on the first hit. That means at 220w, you can't even safely hit it a single time before you are exceeding the safe limits of the battery.
