Dolphin Charger DC-DC Converter - 24/48V - 15A - 99203

DC-DC Converter - 24/48V - 15A

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 youre 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 BOOSTERs assembly process includes conformal coating of the electronic board (PCB) to guarantee an extended lifecycle of your battery charger.
