Victron Energy Skylla-i Battery Chargers – Intelligent, Multi-Bank Charging for Marine and Off-Grid Systems

The Victron Energy Skylla-i series delivers advanced charging solutions for complex battery systems, offering smart functionality, rugged design, and exceptional flexibility. Available in Skylla-i (1+1) and Skylla-i (3) models, these chargers are ideal for marine, industrial, and off-grid applications where reliable power and battery care are critical.

Skylla-i (1+1): Dual-Output Charging:

The Skylla-i (1+1) features two isolated outputs:

Primary Output: Supplies full rated current to the main battery bank.
Secondary Output: Provides a limited 4A charge at slightly lower voltage, ideal for maintaining a starter battery.

Skylla-i (3): Triple-Output Charging:

The Skylla-i (3) model includes three fully isolated outputs, each capable of delivering the full rated charging current. This allows simultaneous, efficient charging of three separate battery banks, ensuring balanced and reliable energy delivery across complex systems.

Key Features:

Rugged Construction: Aluminium housing with epoxy powder coating, stainless steel hardware, and drip shield for resistance to heat, humidity, and salt air. Circuit boards are acrylic-coated for added corrosion protection.
Battery Temperature Protection: Sensors prevent overheating by reducing output in extreme temperatures.
Flexible Configuration: Set up via CAN bus (NMEA 2000), rotary switch, DIP switches, and onboard potentiometers.
Parallel Synchronization: Chargers can be paralleled (same model only) via RJ45 UTP cables for higher output needs.
BatterySafe Mode: Prevents damage from excessive gassing during high-voltage charging.
Variable Absorption Time: Automatically adjusts based on depth of discharge to prevent overcharging.
Storage Mode: Reduces float voltage when batteries are idle, prolonging lifespan and reducing maintenance.
Temperature Compensation: Dynamically adjusts charging voltage based on battery temperature to extend battery life.
Voltage Sense Input: Ensures accurate voltage delivery to compensate for cable loss.
AC & DC Input: Accepts both AC mains and DC power sources.
Power Supply Mode: Stable voltage output allows use as a standalone power supply.
LiFePO₄ (Li-Ion) Ready: Integrates easily with lithium systems via remote control port or full CAN bus communication.

Typical Applications:

Marine vessels with multiple battery banks
Off-grid or backup power systems
Commercial and industrial equipment
Integrated LiFePO₄ BMS-controlled charging
