Victron Skylla-IP65 12V 70A: Professional-Grade Battery Charger for Demanding Environments
Engineered for Reliability in Harsh Conditions
The Victron Skylla-IP65 12/70(3) is a robust, fully sealed battery charger designed to deliver a powerful 70A output across three isolated outputs 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.
Adaptive 7-Stage Charging for Maximum Battery Life
At the core of the Skylla-IP65 12/70(3) is an advanced 7-stage adaptive charge algorithm, meticulously optimised for lead-acid batteries with capacities ranging from 350-700 Ah. 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. This precision charging minimises battery wear and maximises lifespan.
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 13.2V to minimise positive plate corrosion and electrolyte stratification. A weekly refresh charge further prevents sulphation, a leading cause of premature battery failure. The included battery temperature sensor provides automatic voltage compensation, adjusting charge parameters based on ambient temperature—a critical feature for sealed batteries and 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 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 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 equipment.
Advanced Connectivity and System Integration
Built for modern energy systems, the Skylla-IP65 12/70(3) includes a dual RJ45 CAN-bus interface supporting the NMEA2000 protocol. This allows seamless integration with Victron's GX monitoring devices, such as the Color Control GX, and enables synchronised parallel operation of multiple chargers. Simply interconnecting chargers with standard UTP cables ensures coordinated charging, balanced load sharing, and simplified system expansion.
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.

Built to Solve Real-World Charging Challenges
In marine, mining, and remote off-grid installations, charger failure is not an option. The Skylla-IP65 addresses the common failure points of generic chargers—corrosion, overheating, and inaccurate charging—with a design that prioritises protection and precision. Its sealed construction eliminates the risk of salt-laden air corroding internal electronics, while the adaptive charging logic prevents the chronic overcharging or undercharging that silently destroys batteries. By maintaining optimal charge parameters under all conditions, it reduces the total cost of ownership through extended battery life and reduced maintenance interventions.
Whether you are maintaining a critical engine start battery, a house bank on a cruising yacht, or a backup power system in a remote telecommunications shelter, the Skylla-IP65 delivers the reliability and performance required for mission-critical applications.
