Xantrex Echo Charge 12/24VOLT

Xantrex Echo Charge is a compact, high-efficiency auxiliary charger designed to keep your secondary or starting batteries topped up while you’re relying on an inverter/charger or another charging source. Model 82-0123-01 delivers up to 15 A maximum charge current and automatically adapts to either 12-volt or 24-volt battery banks (both banks must share the same DC voltage and battery type).

Effortless, automatic operation means once your house battery bank is being charged, the Echo Charge detects the condition and directs a portion of the charge current to auxiliary or starting batteries. It switches on and off automatically without drawing down or overcharging the in-house bank, maximizing overall charging efficiency and minimizing voltage drop from your primary source. This smart sharing helps you start more reliably and maintain readiness across multiple battery banks.

Designed with safety in mind, the Echo Charge includes built-in thermal and over-current protection and reverse polarity protection, providing peace of mind in rugged environments typical of RVs, boats, and off-grid setups. The unit features a simple, three-wire installation, making setup quick and straightforward while preserving the integrity of your main charging system.
