The Xantrex Echo Charge (part number 82-0123-01) is an auxiliary battery charger built to keep a second battery bank topped off from a single charging source. It's aimed at boaters and RV owners running a house bank alongside a starting battery who don't want to add a second charger to the system. The Echo Charge pulls from an existing inverter/charger, alternator, or other charging source and routes a maintenance charge to the auxiliary battery with minimal voltage drop. It handles both 12 and 24 volt systems, which makes it a practical pick for mixed setups. At $130 for the Xantrex Echo-Charge, it's an inexpensive way to manage two banks.
The Echo Charge monitors the voltage on your primary battery bank and passes current to the auxiliary battery whenever the main bank is being charged. Because it works downstream of your existing charging source, you don't need a separate dedicated charger for the second bank, which saves both money and panel space. The unit is rated for 12 and 24 volt operation, so it fits a wide range of marine and RV electrical systems. It mounts compactly and wires into the system between your charging source and the auxiliary battery. If you're spec'ing out a dual-bank system, pair it with the right gauge marine wire and proper terminals to keep voltage drop down across the run.
This is the part you reach for when you've got a starting battery that needs to stay charged but you only have one inverter/charger feeding the house bank. Common installs include sailboats, powerboats with a dedicated engine-start battery, and RVs with separate chassis and coach batteries. The Echo Charge does its job quietly in the background, keeping the secondary bank ready without you having to manage it.

Yes. The Xantrex Echo Charge supports both 12 volt and 24 volt operation, which makes it suitable for a range of marine and RV electrical systems running either voltage.
No. The Echo Charge is designed to eliminate that need. It works downstream of your existing charging source, so a single inverter/charger or alternator can keep both your primary and auxiliary banks topped off.
