Cloud Size on same juice/batts and coil setup that brings these mods at their full potential. EZ
The advantage for RX so far is that RX supports bigger attys and that plays pretty major role also it uses 3 batts.. I just dunno how much regulation restricts the potential of 3 batteries *parallel?* compared to unregulated series with 2 batts and max 22mm atty.
Series or parallel makes no difference outside of battery life. Regulated 200w is always 200w, series or parallel. Whether the batteries push high-voltage or high-current doesn't affect the coil, since the mod is going to convert to and output the same voltage and current to the coil regardless of how the power is attained. Ohm's law dictates a fixed voltage-current ratio for "x" resistor to achieve "y" wattage. When it comes to reggy boxes, there are several ways to get your power from the batteries, but only one way to give it to the atty.
The RX is set up in series because it's more power-efficient to bring voltage down than it is to generate extra voltage. It's a matter of wasting less power and drawing less current. 3 18650's kick out 12v in series, but the RX200's output caps at 9v, not all that much higher than the cricket. And besides, the input current limit of 23A caps it out at 200w, so even though it can kick out 9v, it can't really make full use of it.
At the 200w max, you can't use the RX's 9v to get more power than the cricket's roughly 8v can push with 30A... ...they even out. If a .3 on the NC gets 200w at 8v, then 8v is all the RX can give the same coil because of the wattage limit. A.4 at 9v on the RX is still only 200w. You feel?
But you're right, you can use large atties with big, super-low sub-ohm coils on the RX200, which you can't do with the cricket without really pushing the batteries.
But you can still do essentially the same thing with the cricket by using big-ass fused claptons and aliens with higher ohms and lots of wraps. Hell, you can stack 4 of them in a velocity-style 22mm if you want. A 25mm atty rigged with double-wides will look goofy as shit on top of the cricket, but it will perform just as well as a super-low sub-ohm 25mm on the RX. Plenty of power to fill em out. I've seen people use 25mm atties very effectively with the cricket.
Power-wise, they really are pretty matched. The real performance differences are gonna be the battery life and the hit. Do you like the slower, more building mech hit? Or the straight-to-the-chest reggy hit? Which one's easier and more comfortable for you?
Personally, I think 200w is a lot of power to be having that regulated push behind. Unregulated's smoother hit might make it easier to get a deeper hit.
With both maxed, it's pretty much same power, same mass, same vapor output... ...but different
feel. The RX200 delivers flat, even power, while the NC is peaky. That's the only key difference.
