Worthwhile to change out my Parallax 7300 Converter/Charger?

Hello folks, For years I have read that the factory converter/chargers on most RVs don't usually charge the storage batteries very well. With tax returns I finally have a little money to change out...

Yes. The battery charges much faster. I don't have numbers but it is a very noticeable change. The Parallax charges at 3.8v, or something less due to the resistance of the wiring between the converter and the battery. The PD charges at 4.4v when the battery is low. I replaced the existing #8 wire with #4 to reduce the resistance.
