Xantrex Heart Echo Charge Charging Panel
Xantrex Heart Echo Charge Charging Panel — Product description
Imagine heading out on a weekend adventure in your RV or boat, only to find your starting battery dead because the house batteries drained it overnight. That's a common frustration for off-grid enthusiasts, but the Xantrex EchoCharge changes the game. This clever device acts like a smart middleman, channeling excess power from your primary house battery charger straight to your auxiliary or starter battery—without the usual voltage losses that plague traditional setups.
Unlike bulky diode isolators that rob precious volts from your charge cycle, the EchoCharge uses advanced digital sensing to kick in precisely when your house bank hits 13V (12V mode) or 26V (24V mode). It then delivers up to 15 amps of clean, efficient charging to keep everything topped off, automatically switching off to prevent overcharge or interference with your main bank.
Why Choose the EchoCharge for Your Dual Battery Setup?
RVers, boaters, and solar power users swear by this unit for its seamless integration. It taps into spare current from your inverter/charger, alternator, or shore power source, ensuring your engine-starting battery stays ready while your house batteries power lights, fridges, and gadgets. No more babying your batteries or worrying about cross-drainage—it's all handled automatically.
- Zero Voltage Drop: Digital design bypasses the inefficiencies of diode-based systems, delivering full-strength charge to aux batteries.
- Universal Fit: Handles both 12V and 24V systems effortlessly (as long as both banks match).
- Safety First: Over-current, thermal shutdown, and reverse polarity protection keep things reliable in harsh marine or RV environments.
- Plug-and-Play Simplicity: Just three wires to connect—positive from charger, positive to aux battery, and a ground. Install it in minutes, no electrician needed.
Perfect for RVs, Boats, and Off-Grid Living
In an RV, pair it with your converter/charger to keep the chassis battery happy during long boondocking trips. On the water, it ensures your thruster or generator starter battery mirrors your house bank's charge from solar panels or the alternator. Off-grid solar warriors love how it maximizes every amp from limited panels, preventing starter battery neglect.
Users report extending battery life noticeably because it maintains optimal float levels without constant cycling. Think of it as your battery system's quiet guardian, working invisibly until needed.

Quick Installation Guide for DIY Success
- Disconnect all battery negatives for safety.
- Connect the red wire from your primary charger's output to the EchoCharge input.
- Run the output wire to your aux/starter battery positive.
- Ground the black wire to a solid chassis point.
- Double-check polarity, reconnect batteries, and test—charge should flow above trigger voltage.
Pro tip: Mount it away from heat sources and use appropriately sized wire (10-12 AWG recommended for 15A runs) to minimize resistance.
Frequently Asked Questions
Xantrex digital echocharge (part#82-0123-01) is designed to charge auxiliary or starting batteries from an inverter/charger or other charging source with limited voltage drop. The Xantrex echocharge detects when the house battery bank is being charged and directs a portion of the charge current to auxiliary or starting batteries. The maximum charger current offered by echocharge is limited to 15 amps.
