Victron Skylla-i 24/100 (3): Industrial-Grade 24V 100A Multi-Bank Battery Charger

Advanced Adaptive Charging for Professional Marine, Automotive, and Off-Grid Systems

The Victron Skylla-i 24/100 (3) is a high-performance, microprocessor-controlled battery charger engineered for demanding environments where reliability and precision are critical. Delivering up to 100 A across three fully rated outputs, it simultaneously charges three independent battery banks without compromise, making it an ideal solution for commercial vessels, emergency vehicles, and large off-grid power systems.

Unlike conventional chargers that divide current between outputs, each of the three isolated outputs can supply the full 100 A, ensuring rapid, complete charging even under heavy load. The integrated 7-stage adaptive charge algorithm automatically adjusts absorption time based on depth of discharge, preventing overcharging after shallow cycles and ensuring full recovery after deep discharges. This extends battery service life and reduces maintenance in critical applications.

Built for Harsh Environments

Housed in a robust aluminium epoxy powder-coated case with a drip shield and stainless steel fixings, the Skylla-i withstands heat, humidity, and salt air. Internal circuit boards receive an acrylic conformal coating for maximum corrosion resistance, while temperature sensors automatically derate output current under extreme conditions to protect power components. These features make it a trusted choice for marine, coastal, and industrial installations where lesser chargers fail prematurely.

Intelligent Battery Management

The Skylla-i incorporates Victron's advanced BatterySafe mode, which limits voltage rise once gassing voltage is reached, preventing excessive gassing and electrolyte loss. The Storage mode reduces float voltage to 26.4 V after 24 hours of inactivity, minimising positive plate corrosion and electrolyte stratification, with a weekly refresh cycle to prevent sulphation. An included battery temperature sensor enables automatic voltage compensation, essential for sealed lead-acid batteries and environments with wide temperature swings.

Flexible Integration and Control

With a galvanically isolated CAN bus (NMEA2000) interface, the charger supports synchronised parallel operation of multiple units via RJ45 cables, scaling to meet large battery banks. A rotary switch, DIP switches, and potentiometers allow fine-tuning of charge parameters for specific battery chemistries, including LiFePO4. Remote on-off control via a BMS relay or optocoupler output enables seamless integration into lithium systems, while the voltage sense facility compensates for cable losses, ensuring precise charge voltage at the battery terminals.

Applications

This charger is purpose-built for professional and heavy-duty applications where downtime is not an option. Typical use cases include:

• Commercial marine vessels with multiple battery banks (house, start, thruster)
• Emergency service vehicles requiring reliable, fast charging
• Off-grid solar systems with large lead-acid or lithium battery banks (500-1000 Ah)
• Industrial backup power and telecommunications sites
• Mobile workshops and field service trucks

Why Choose the Skylla-i Over Standard Chargers?

Standard multi-bank chargers often split total current across outputs, leading to extended charge times when one bank is deeply discharged. The Skylla-i's three full-current outputs eliminate this bottleneck. Its adaptive algorithm and environmental hardening reduce the risk of battery damage from overcharging, undercharging, or corrosion-related failures, common in generic-grade chargers. For lithium systems, the CAN bus interface provides precise control beyond simple on-off switching, ensuring safe, efficient charging profiles.

With a power factor of 0.98 and wide input voltage range, it operates efficiently on generators and unstable grid supplies, reducing generator run time and fuel consumption. The alarm relay (DPST) provides remote monitoring of charge status or fault conditions, enhancing system oversight.

Technical Highlights

The charger connects via M8 bolt terminals for secure, low-resistance battery connections, and the 230 VAC input uses screw-clamp terminals accepting up to 10 mm² cable. Forced cooling with temperature-controlled fans maintains full output up to 40°C ambient, with derating to 60°C. The IP21 rating suits protected indoor or enclosed installations.

Note: For optimal performance, ensure adequate ventilation and use appropriately sized cables to minimise voltage drop.
