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.
Batteries hate being overcharged or undercharged, and this charger's microprocessor brain takes care of that automatically. It cycles through three stages:
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.
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.
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).
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.
Yes, it's fully compatible with LiFePO4 lithium-ion batteries, using dedicated profiles to prevent overcharging and match their unique voltage curves.
Three-stage (bulk, absorption, float) fully optimizes and maintains batteries for longevity. Two-stage skips float for quicker cycles on deeply discharged packs.
Any orientation works due to its drip-proof design. Secure with screws on a flat surface, ensuring good airflow around vents.
Absolutely—90-265V AC input covers 120V US, 230V Europe, and 240V Australia, plus 47-63Hz for generators.
Each bank charges independently, so mix flooded starting, AGM house, and lithium thruster batteries—no issues.
Reverse polarity, DC over-voltage, over-temperature, circuit breaker on AC, and surge/spike protection keep everything safe.
Quiet mode minimizes fan noise, making it suitable for liveaboards or campground stays.
TRUECHARGE™3 30A 3 Bank Battery Charger - 24V
TRUEcharge3 battery chargers lead the industry with a small footprint and ultra-compact design. In addition to meeting global safety and regulatory standards, TRUEcharge3 battery chargers feature low electrical interference and efficient power factor-corrected multistage charging. Thanks to their inherent drip-proof design characteristics, the TRUEcharge3 Chargers can be mounted in multiple positions. Unlike its predecessors, TRUEcharge3 is lithium-ion battery compatible.
Designed for recreational and commercial applications worldwide, TRUEcharge3 accepts 90–265 Vac, and 47–63 Hz, which makes traveling abroad and handling poor-quality power a breeze. The easy-to-read display of the TRUEcharge3 24 V models can be enhanced with an optional remote panel. Each model comes with built-in protection against surges and spikes on the AC power line.

Protection Features:
Three-Stage Charging
Multistage charging ensures batteries receive optimum charging, but with minimal wear and tear, regulating the voltage and current delivered to the batteries in three automatic stages:
Power Factor Corrected (PFC) Charging
Less shore power is required for charging batteries, freeing up more usable AC power for running electrical devices and appliances and reducing the likelihood of tripping shore power breakers.
