Victron Skylla IP 65 12/70 Battery Charger
A powerful, waterproof and intelligent battery charger with a 7-stage adaptive charging algorithm, suitable for a wide range of battery types and battery chemistries, with a dedicated lithium-ion charging algorithm.
The wide range of universal input voltage increases installation flexibility, and the charger maintains its full output power regardless of where in the world it is located.
Thanks to its IP65 protection rating, this charger is particularly suitable for use in marine applications, mobile applications and industry, and withstands harsh environmental conditions: heat, humidity and salt air.
Skylla-IP65 (1+1): two outputs for charging two battery banks
The Skylla-IP65 (1+1) has 2 separate outputs. The second output is intended for charging the starter battery. Consequently, it is limited to 3 A and has a slightly lower output voltage for maintenance charging of the usually full starter battery.
Skylla-IP65 (3): three full-current outputs for charging 3 battery banks
The Skylla-IP65 (3) has 3 separate outputs. All outputs can deliver the full rated output current. IP65 protection Epoxy powder-coated steel housing and splash-proof. Withstands the challenges of a harsh environment: heat, humidity and salty air. An acrylic coating provides maximum protection for the circuit boards against corrosion. Temperature sensors ensure that the power components are always operated within the specified limits. Under extreme environmental conditions, the output current is automatically reduced if necessary.
LCD display
For status monitoring and easy adjustment of the charging algorithms to a specific battery and its operating conditions. CAN bus interface (NMEA2000) For connection to a CAN bus network, a Skylla-i control panel or the Color Control digital display. Synchronized parallel operation Multiple chargers can be connected in parallel and synchronized with the help of a CAN bus interface. This is achieved by simply connecting the chargers to each other via RJ45 UTP cables.
The right amount of charge for a lead-acid battery: adaptive absorption time
If only slight discharges occur, the absorption time is kept short to prevent overcharging of the battery. After a deep discharge, the absorption phase is automatically extended to ensure that the battery is fully charged.
Prevention of damage caused by excessive gassing:
The BatterySafe mode To shorten charging time, the highest possible charging current is combined with a high constant voltage. However, to prevent excessive gas development towards the end of the bulk phase, the Skylla-IP65 limits the rate of voltage increase once the gassing voltage has been reached.
Less maintenance and aging during battery idle periods:
The storage mode Storage mode is activated whenever no discharge has occurred within 24 hours. In storage mode, the float voltage is then reduced to 2.2 V/cell (26.4 V for a 24 V battery) to minimize gassing and corrosion at the positive plates. Once a week, the voltage is raised back to the absorption threshold to 'refresh' the battery. This achieves a kind of equalization charge that prevents electrolyte stratification and sulphation - the two main causes of premature battery failure. Longer battery life through temperature compensation A battery temperature sensor is supplied with every Skylla-IP65 unit. The temperature sensor ensures that the charging voltage decreases as battery temperature rises. This is particularly important for gel batteries or when consistently high temperature fluctuations are expected.
Battery voltage sensor
To compensate for voltage losses caused by cable resistance, the Skylla-IP65 has a voltage sensor in the charging circuit so that the battery always receives the correct charging current.
Use as a power supply
Thanks to its excellent control circuit, the Skylla-IP65 can be used as a power supply with a perfectly stabilized output voltage when no batteries or large buffer capacitors are available.
Suitable for lithium-ion batteries (LiFePo4)
A simple on/off control can be implemented by connecting a relay or an optocoupler open-collector output from a Li-Ion BMS to the charger's remote control connection. Alternatively, voltage and current can be fully controlled by establishing a connection to the CAN bus interface.
