The ProSport doesn’t have the capability of running multiple charging profiles for different banks. But I think the basic difference here is what type of AGM battery you are using. The charger has a Flooded / AGM setting, using the same profile / rates for both and then a “HP AGM” setting, which one would use on batteries such as Optima Sprial Wound, Odyssey, etc. It also has a Gel setting.
I think it’s pretty easy to identify the difference in batteries when shopping. Example of a Group 24 AGM ... the standard marine “dual purpose” AGM might run $200. A HP or a “thin plate pure lead” AGM would typically run over $300. But yes, I do have the capability of running the charger (and all other charging sources) only to the house bank and then using an echo-charger or other device. The echo charger will follow the charging profile of the charger that is connected but will limit the amperage passed to the 2nd bank depending on the voltage difference sensed between the two banks ... which isn’t a huge feature as I understand a battery will consume only the amps it needs. It’s 15 amp maximum for the echo-charger. Also voltage passed is limited to 14.4. I don’t know if there is any benefit or not to using the “reserve” as a conventional “start” .... but I’d have to remember to switch banks after running the engine.

AGM for start and Flooded for house. Each type of battery requires different charge profiles. With the same chemisty the ACR allows for a higher current charge to switched bank. The echos are limited to 20Amps...IIRC. I too am eager to hear why Rich is partial to the echo. Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD
