If one wants to use thicker cables than will fit in the cable receptacles, there are adapters available, or one can simply destrand at the connection until it fits. It's not going to cause any measurable voltage drop or excessive heating destranding a 0 gauge cable to 4 awg at the connection. The thicker copper cable will help wick away any extra heat. Do be sure to retorque it after a few cycles though.
The Pd is a good converter. The ability to manually force one of the three voltage stages is awesome. I am only annoyed by their marketing, calling the 4th stage , that 15 minute blast to 14.4 or 14.8 every 16 hours from 13.2v "equalization' instead of destratification.
True equalization is accepted as applying voltages over 15.3v, to as high as 16.2v, after the battery has already been held at a regular absorption voltage until amperage quit tapering in order to max out the specific gravity of all cells. To call Destratification which is simply inducing gassing voltaegs for a period of time to stir the electrolyte, 'equalization', annoys me, but I still recommend their converters for those who require automatic, as at least this Automatic, has the option of manual override.
I've installed two pd9245s for those needing automatic but liked the idea of manual override, and an Iota DLS-45 for the one person who said they would never manually override it even if they knew when why or how that would be desirable.
I like the Manual powermax adjustable voltage models too. The older 100 amp model I have modified with a 60mm continuous running fan opposite the provided 80mm fan, and calibratable illuminated voltmeter on a switch, and with 10 turn 500 ohm bourns potentiometer, makes only 94 amps, but that is likely as it is near maxing out the 15 amp household AC circuit and is not getting 115vac+ from it. It goes as high as 15.5v. Adjustable voltage is great when charging in hot or cold climates or multiple batteries that ask for wildly different setpoints, or when one simply hates anything 'automatic' which falls so short so often that it negatively affects battery longevity and enjoyment one can have when the batteries are not prematurely dying from chronic undercharging in back to back nightly deep cycle duty.
Powerpole princesses that rarely or never boondock, with their dual 12v group 24 marine/rv batteries are 'just fine' with the Manufacturer provided Wfco, until it fails anyway.
