DESCRIPTION
Victron Skylla-IP65 24/35(1+1): Professional-Grade 24V Battery Charger for Demanding Environments
Engineered for Reliability in Harsh Conditions
The Victron Skylla-IP65 24/35(1+1) is a robust, fully sealed battery charger designed to deliver dependable power in the toughest environments. Its IP65-rated steel enclosure, finished in a durable epoxy powder coat, provides complete protection against dust and water ingress, making it ideal for marine, industrial, and off-grid applications where exposure to moisture, salt air, and extreme temperatures is a constant challenge. Internal circuit boards receive an additional acrylic conformal coating, offering superior corrosion resistance and ensuring long-term reliability even in high-humidity settings.
Unlike standard chargers that can fail prematurely under thermal stress, the Skylla-IP65 employs active forced-air cooling and integrated temperature sensors. These sensors continuously monitor critical power components, automatically reducing output current if necessary to prevent overheating and maintain operation within safe limits, even at ambient temperatures up to 60°C. This intelligent thermal management significantly reduces the risk of charger failure and extends service life.
Dual-Output Configuration and Adaptive 7-Stage Charging
This (1+1) model features two isolated outputs: a powerful 35A main output for your primary battery bank and a dedicated 3A output specifically designed to maintain a starter battery. At the core of the Skylla-IP65 is an advanced 7-stage adaptive charge algorithm, meticulously optimised for lead-acid batteries. This intelligent system dynamically adjusts the absorption phase duration based on the depth of the previous discharge—shortening it after shallow cycles to prevent overcharging, and extending it after deep discharges to ensure a full, complete recharge.
For sealed batteries, the BatterySafe mode actively prevents excessive gassing by limiting the rate of voltage increase once the gassing threshold is reached, protecting the battery from damage. When the battery remains idle for 24 hours, the Storage mode automatically engages, reducing float voltage to 26.4V to minimise positive plate corrosion and electrolyte stratification. A weekly refresh charge further prevents sulphation, while the included battery temperature sensor provides automatic voltage compensation—a critical feature for installations subject to wide temperature swings.
Precision Charging with Voltage Sense and Power Supply Mode
Voltage drop across long cable runs can compromise charging accuracy. The Skylla-IP65 24/35(1+1) features a dedicated voltage sense input that measures the actual battery terminal voltage, automatically compensating for cable losses to ensure the battery receives the precise charge voltage required. This is particularly valuable in large marine installations where the charger may be located some distance from the battery bank.
Thanks to its exceptionally stable output regulation, the Skylla-IP65 can also function as a high-quality DC power supply when batteries or large buffer capacitors are not available, providing clean, regulated power for sensitive 24V equipment. The integrated LCD display allows for easy status monitoring and simple adaptation of the charge algorithm.
Advanced Connectivity and System Integration
Built for modern energy systems, the Skylla-IP65 includes a dual RJ45 CAN-bus interface supporting the NMEA2000 protocol. This allows seamless integration with Victron's GX monitoring devices, such as the Cerbo GX, and enables synchronised parallel operation of multiple chargers. Simply interconnecting units with standard UTP cables ensures coordinated charging and balanced load sharing.
For lithium-ion (LiFePO4) battery banks, the charger offers flexible control options. A remote on-off port accepts a signal from a battery management system (BMS) for simple charge enable/disable control, while the CAN-bus port allows complete, real-time control of charge voltage and current for fully integrated lithium systems.
