Dolphin Booster Series

The Dolphin Booster Series offers professional-grade marine battery charger on board solutions, designed to intelligently charge auxiliary battery banks from a primary DC source. Perfect for commercial and leisure vessels, these DC/DC chargers seamlessly upgrade existing systems without rewiring.

With flexible voltage configuration, 4-stage smart charging, effortless installation, and robust safety features, the Booster Series stands out as the best battery charger for marine batteries used onboard.

Key Features & Technical Performance

Intelligent 4‑Stage Charging (IUUo)

Automatically adapts performance across battery chemistries—Lead Acid, AGM, Gel, Lithium, LiFeSO₄—to ensure fast, safe, and precise energy delivery.

Automatic Source Protection

Self-regulating design prevents depletion of the primary battery bank while charging the auxiliary bank—ideal for vessels with bow thrusters, service loads, or dual-voltage systems.

Compact, Durable Construction

Roughly half the size of a traditional DC/DC charger with equivalent output. Conformal-coated circuit board (PCB) improves corrosion resistance in harsh marine environments. Easy to install—only four fixing bolts and electrical connections needed.

High Efficiency & Wide Operating Range

With ~90% efficiency, energy utilization is maximized. Handles input currents up to 70A (12/24 or 24/24 models) or 35A (24/48 model). Operates reliably from –10 °C to +55 °C.

Dolphin Booster Series – Model Overview

Recommended Applications – Real-World Onboard Scenarios

The Dolphin Booster Series is ideal for onboard dual-voltage setups, without needing full rewiring:

• Charter catamarans with 24V bow thrusters: Charge directly from a 12V house system using the 12/24V model.

• Commercial vessels with dual 24V banks: Keep both the starter and service batteries topped off independently.

• Lithium retrofit systems (LiFePO₄ or 48V): Use the 24/48V model to integrate a 48V house bank without changing alternators or isolators.

• Trolling motor setups (36V): Power 36V motors from a 24V system in utility or fishing boats—ideal where space is limited.

• Power redundancy for long-range cruisers: Maintain backup service batteries without draining the primary supply.

These use cases make the Dolphin Booster a flexible marine charger battery for demanding and evolving onboard systems.
