Dolphin Premium Series Battery Chargers for Marine Use

The Dolphin Premium Series Battery Chargers are advanced, compact, and efficient devices designed to meet the demands of modern battery technologies. These chargers are ideal for marine applications and compatible with various battery types, including Lithium-Ion-Iron-Phosphate batteries. With robust features and multiple configurations, they provide reliable and versatile performance.

Features and Benefits

The Dolphin Premium Series Battery Chargers offer numerous advanced features tailored to meet the needs of professional and recreational users. These include:

1. Compact and Durable Housing

The Dolphin Premium Series features a slim, low-profile design built to save space in tight compartments like engine rooms, navigation lockers, or behind cabinetry. Despite their compact form, the housings are reinforced with marine-grade materials to resist corrosion, moisture, and vibration—key challenges in onboard environments. Quick-connect AC/DC terminals and flexible mounting brackets make installation fast and secure, whether retrofitting an older system or outfitting a new build.

2. Smart Charging for Lithium and More

These chargers are engineered to support a wide range of battery chemistries—including Lithium Iron Phosphate (LiFePO₄), AGM, gel, and flooded lead-acid. Each unit includes pre-programmed charging curves that users can select internally via dip switches. For lithium batteries with BMS (Battery Management System), Dolphin provides a dedicated algorithm that ensures accurate voltage limits, current regulation, and thermal control, preventing overcharge or imbalance across cells. This makes them ideal for modern hybrid and electric propulsion systems.

3. Digital Control via RISC Microcontroller

At the core of each charger is a high-performance RISC microcontroller that governs the charging process with precision. This digital brain adjusts power delivery in real time based on battery status, temperature, and load demand. The internal dip switch panel allows installers to easily configure the system for the correct voltage and battery type, making Dolphin chargers technician-friendly yet advanced enough for professional fleets.

4. Multi-Bank Charging

Every Dolphin Premium charger comes with three fully isolated DC outputs, allowing independent charging of multiple battery banks—such as start, house, bow thruster, or auxiliary batteries. Each output receives optimized current regulation, preventing one weak battery from affecting the rest. This makes Dolphin an excellent solution for multi-bank setups on yachts, catamarans, commercial vessels, or even mobile service trucks and industrial backup stations.

5. Global Input Compatibility (115/230V)

With automatic input voltage detection and switching, Dolphin Premium chargers can operate seamlessly with shore power systems around the world, including North America (115V) and Europe/Asia (230V). The chargers are also compatible with both 50Hz and 60Hz AC systems, making them ideal for global cruisers, liveaboards, or fleet vessels that dock in ports across different electrical zones. You’ll never need a step-down transformer or manual conversion.

6. Silent Night Mode

Noise-sensitive environments, such as cabins, medical boats, or luxury yachts, benefit from Dolphin’s manual night mode feature. This mode disables the cooling fan, reducing operational noise to nearly zero during sleeping hours or when silent operation is required. While active, the charger continues to function at reduced current, preserving battery health while offering maximum acoustic comfort.

7. Automatic Weekly Equalization

Certain models (e.g., 12V–40A and 24V–20A) include a built-in weekly equalization cycle, which helps restore battery performance by eliminating charge stratification and reducing sulfation on lead-acid plates. This periodic high-voltage boost extends battery lifespan and maintains charge capacity, making it particularly valuable for vessels with large house banks or limited charging time at dock.

8. TouchView Controller Support

The higher-output models—such as the 12V–60A and 24V–30A—are compatible with Dolphin’s TouchView remote display, a powerful interface that lets users monitor and control charger activity from anywhere onboard. The TouchView shows real-time data including voltage, amperage, charging stage, battery status, and any system alerts. It’s an excellent upgrade for fleet managers, charter operators, or owners who want full visibility over their onboard energy system.
