Peter I take back everything I stated about the echo-charge. For some reason I was under the impression that it was the equivalent of a DC-DC charger and could be programmed/selected for different battery chemistries. After re-reading the owners manual I can not understand any advantage/difference compared to an ACR and am even more eager for Rich to tell us why he so strongly prefers the echo.
As for using the reserve as a start, the idea would be to run new cables from the reserve battery to the starter. The 1-ALL-2 switch would always stay on 1. The auxiliary loads would come off the house battery (#1) and the alternator would only be connected to the house battery. The echo-charge/ACR provides charge current to the starting battery when the house bank is full...ish (> ~12.7v). When you go to start, the starting battery is the only one providing power since the echo-charge opened the connection when the charger/alternator was disconnected/shutdown. Remember this is all so that you don't ever have to switch the 1-ALL-2 switch. Even more so that there isn't any temptation to do it while the engine is running.
