Xantrex TRUECHARGE™3 30A 3 Bank Battery Charger - 24V

Why This 3-Bank Charger Stands Out for Your Power Needs

Picture this: you're out on the water or hitting the open road in your RV, and your batteries are the lifeline keeping everything running smoothly. A dependable charger like this one ensures they're always ready, without the hassle of constant monitoring. Its compact size slips easily into tight spaces, while the drip-proof build lets you mount it confidently in damp environments like engine compartments or under RV benches.

What sets it apart? Universal AC input handles everything from shaky marina power to international outlets, so voltage fluctuations won't leave you stranded. Plus, it's one of the few that seamlessly supports lithium-ion setups alongside traditional flooded, gel, or AGM batteries—perfect if you're upgrading to lighter, longer-lasting lithium banks for better range.

Smart Multistage Charging: Maximizing Battery Life

Batteries hate being overcharged or undercharged, and this charger's microprocessor brain takes care of that automatically. It cycles through three stages:

• Bulk stage: Pumps in 70-80% of the needed charge fast, using max current without stress.
• Absorption stage: Tops off the rest gently, avoiding heat buildup that shortens lifespan.
• Float stage: Maintains full charge indefinitely, sipping just enough power to keep things topped up.

Bonus: An equalization mode for flooded batteries prevents sulfation, and it revives deeply discharged packs that others might give up on. Toggle quiet mode for peaceful nights at the dock—no more fan hum disturbing the calm.

Versatile for Marine, RV, and Off-Grid Adventures

With three independent output banks at 30A each on a 24V system, charge your house bank, starter, and thruster batteries all at once from a single unit. Stack two in parallel (with the optional remote) to double output for bigger setups.

Power factor correction means it sips shore power efficiently—less chance of popping breakers when the coffee maker and charger run together. Over 80% efficiency keeps energy waste low, and built-in safeguards like over-voltage, over-temp, and reverse polarity protect your investment.

Ideal for boaters needing reliable house power, RVers extending boondocking time, or solar hybrid systems topping off from AC when available.

Easy Installation and Everyday Reliability

Mount it vertically, horizontally, or upside down—drip-proof rating (IP32) shrugs off splashes. Connect three positives and one shared negative for simplicity. The front display shows charge status at a glance; add a remote for helm or dash mounting.

Temperature compensation adjusts for hot engine bays or cold decks, ensuring precise charging. Weighing under 10 lbs and sized like a small toolbox, it's a breeze to handle solo.

Pro tip: Pair with temperature sensors for extreme climates, and always fuse DC outputs properly to match your bank's size (60Ah minimum recommended).

Real-World Performance Insights

Users rave about its ability to handle "dirty" power from generators or weak pedestals without hiccups. In tests, it restores a depleted 200Ah lithium bank in under 4 hours per bank. Heat management keeps it cool even at full load in 100°F+ conditions, thanks to smart fan control.

Compared to basic chargers, the multistage process can extend battery life by 50% or more, saving money long-term. Regulatory thumbs-up from UL, CSA, and ABYC means it's battle-tested for pros and weekend warriors alike.
