How do I know how much power/heat our RDAs and tanks can handle?
Any thoughts?
Thanks!

Your build and wattage applied to that build will, with regulated APVs, determine perceived vape temperature. Vape temperature, or coil radiant heat value - as used in the Steam Engine coil model program is, for the purposes of this example - measured as "heat flux" and expressed as (mW/mm²) milliwatts per millimeter of coil surface area, squared.
To arrive at your desired temperature, it's good to know what you currently prefer. If for example you produce a single coil build using 28 gauge wire at 1.2Ω (the lower resistance limit where you can obtain "Ohm's law parity" with the MVP2 maximum of 3 amps / 11 watts), and apply that wattage to it... your heat flux value is 163 mW/mm².
For reference - my builds and power supplied to those builds - usually run between 250 and 350 mW/mm², depending on the atty, power supply and juice variables.
If the reason you're buying high(er) wattage APVs is to obtain a warmer vape, that's easily accomplished with the right build... all the way to the point of uncomfortably hot.
If you're going this route so that you can dip into sub-ohm,
where you can benefit from greater coil surface area and the resultant higher level of flavor and/or vapor that surface area can provide... that's not difficult either.
For both however... you need to understand what you're doing and why.
I'd like you to click on the first two sigline hyperlinks below. The first is the previously mentioned Steam Engine program, the second is my advanced user guide article, which will explain not only the basics, but provide useful information on critical values like heat flux... and the optimal balancing act between wattage and build variables.
