Victron Skylla-IP65 12/70 (1+1) 120-240 V battery charger

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 special lithium-ion charging algorithm.
The wide range of universal input voltage increases installation flexibility, the charger maintains its full output power regardless of where in the world it is located.
Due to its IP65 protection rating, this charger is particularly suitable for use in shipping, mobile and industrial applications and can withstand adverse 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 to maintain the charge of the usually full starter battery.

Skylla-IP65 (3): three full power 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 difficult environment: heat, humidity and salty air. An acrylic coating protects the circuit boards against corrosion as best as possible. Temperature sensors ensure that the power components are always operated within the specified limits. In extreme environmental conditions, the output current is automatically reduced if necessary.

LCD display
For status monitoring and easy adaptation of the charging algorithms to a specific battery and its operating conditions. CAN-Bus Interface (NMEA2000) For connection to a CAN-Bus network, to a Skylla-i control panel or to the Color Control digital display. Synchronized parallel operation Several chargers can be connected in parallel and synchronized using a CAN-Bus interface. This is achieved by simply connecting the chargers to each other using RJ45 UTP cables.

The right charge amount for a lead-acid battery: adjusted constant voltage time
If only weak discharges occur, the constant voltage time is kept short to avoid overcharging the battery. After a deep discharge, the constant voltage phase is automatically extended to ensure that the battery is fully charged.

Preventing damage caused by excessive gassing:
The BatterySafe mode To shorten the charging time, the highest possible charging current in combination with a high constant voltage is aimed for. However, to avoid excessive gas development towards the end of the constant current phase, the Skylla-IP65 limits the speed of the voltage increase after the gassing voltage has been reached.

Less maintenance and aging when the battery is idle:
Storage mode Storage mode is activated whenever no discharge has taken place within 24 hours. In storage mode, the float charge voltage is then reduced to 2.2 V/cell (26.4 V for a 24 V battery) to minimize gas development and corrosion on the positive plates. Once a week, the voltage is increased back to the constant voltage threshold to 'refresh' the battery. This creates a type of equalization charge that prevents electrolyte stratification and sulfation - the two main reasons for premature battery failure. Longer battery life through temperature compensation A battery temperature sensor is supplied with every Skylla-IP65 device. The temperature sensor ensures that the charging voltage decreases as the battery temperature increases. This is particularly important for gel batteries or when constant 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 source
Due to the excellent control circuit, the Skylla-IP65 can be used as a power source 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 open collector optocoupler output from a Li-Ion BMS to the charger's remote control port. Alternatively, voltage and current can be fully controlled by connecting to the CAN bus port.
