99201 - Dolphin Charger DC Converter - 12/24V - 30A

DC-DC Converter - 12/24V - 30A

Your boat has a 12V alternator, and you need to charge a 24V or 36V battery “on the run”? Dolphin has the solution. Our boosters are true DC/DC chargers with a 3-stage smart charge feature. Compatible with 4 different technologies, including Gel, AGM, or Lithium LIFEPO4. Dolphin booster is the perfect choice to charge your bow thruster or trolling motor batteries!

Flexibility & Versatility

BOOSTER units are designed to charge a 24V, 36V or 48V auxiliary battery from a single 12V or 24V power system, ideal for new installations or for updating older systems. Thanks to recharging during navigation, auxiliary batteries are always available. No need to wait until you’re connected to the shore to recharge. This product range extends from 12/24V (charging at 30A), 12/36V (charging at 20A) up to 24/48V (charging at 15A).

Efficient Power Conversion

Small is beautiful: our engineers have made it compact. BOOSTER is only half the size of a conventional charger of equivalent power!

Faster Charging Times

BOOSTERS are intelligent marine battery chargers featuring an advanced and unique 4-stage charging program. This reduces charging time by 50% compared with charging from a basic alternator. with different battery chemistry settings (Lead, Gel, AGM, Lithium, LifeFO4).

Compatibility with Different Voltages

BOOSTERS are smart battery chargers featuring four different battery profile, Lead, Gel, AGM, and Lithium LifeFO4.

Protection Features

BOOSTER units include automatic protection against battery source drainage, over-current, over-voltage and reverse polarity and built-in fuses protections.

As for all other Dolphin® charger products, the BOOSTER’s assembly process includes conformal coating of the electronic board (PCB) to guarantee an extended lifecycle of your battery charger.

The Dolphin Charger DC-DC Converter (part number 99201) is a heavy-duty voltage converter designed for marine and similar applications requiring efficient power management. It enables the charging of 24V or 36V auxiliary batteries from a 12V or 24V power system, such as an alternator. This unit is suitable for IT professionals and system integrators managing power solutions in environments where auxiliary batteries, like those for bow thrusters or trolling motors, need reliable charging while on the move. It addresses the challenge of maintaining auxiliary battery readiness without requiring shore power, offering a compact solution half the size of conventional chargers. The converter features a 3-stage smart charge and an advanced 4-stage charging program, which can reduce charging times by 50% compared to basic alternator charging. It supports various battery chemistries, including Gel, AGM, and Lithium LiFePO4, and incorporates protection features against battery source drainage, over-current, over-voltage, reverse polarity, and includes built-in fuses.
