There's nothing internal on the board, IIRC - voltage regulator but that's all. The connector's keyed so polarity being correct is the responsibility of the cable.

With respect to overvoltage/overcurrent protection there's none needed. If you overload the mount weight-wise it's going to have issues regardless of what you do extrinsically.

If you're worried about having enough capacity in your supply to provide sufficient current (and thus keep the voltage steady etc) then you want capacitors, not a boost-buck converter, but I don't know of anyone who has done that. Capacitors bring their own issues. I'd stick to a good-quality power supply.

I am planning to use a 12 volt to 15 120 watt converter between my power supply (usually going to be battery) and the mount. My reasoning is I want to be able to accommodate different battery systems without worrying about under voltage issues.  The converter is touted as high efficiency, so.... One caveat, I'm an engineer so I'm comfortable with insuring correct polarity and what not. All the reasonably priced converters I've found are definitely aimed toward folks that like to tinker,  definitely not plug and play.
