I frequently park my diesel motorhome in the back yard, for an extended period of time, and plug it into 30 amp power. This keeps my house batteries topped off but does nothing for the chassis/starter battery. I have heard that echo chargers (also called Automatic Charging Relays (ACR) will charge the Chassis battery. Per the literature, the ACR is connected to the inverter output that charges the house batteries and sends a charge to the Chassis battery. Does anyone have experience with these systems? One concern I have is that my chassis battery is about 15 feet away from the house battery bank and inverter and I wonder if there will be too much a voltage drop over that distance.
