Victron Skylla-i 24/80 (1+1) 230V Battery Charger 80A 24V

Victron Skylla-i Battery Charger for 24V Batteries

One full-rated output and a 4A auxiliary charging output are available. The charging voltage can be precisely adjusted to any battery system.
The charger's input is 230 V at 50/60 Hz. The charging voltage can be measured directly at the battery terminals to compensate for voltage drop due to cable resistance. An external sensor allows measuring the battery temperature and compensating the charging voltage accordingly.

Reduced maintenance and aging when the battery is idle: 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 of the positive plates.
Once a week, the voltage is returned to the constant voltage threshold to 'refresh' the battery. This achieves a form of equalization charge that prevents electrolyte stratification and sulfation – the two main reasons for premature battery failure.

Robust
The epoxy powder-coated aluminum casing with drip protection and stainless steel brackets withstands even the harshest environmental conditions: heat, humidity, and salty air. An acrylic coating provides the best possible protection against corrosion for the circuit boards.
Temperature sensors ensure that the power components always operate within specified limits. Under extreme environmental conditions, the output current is automatically reduced if necessary.

Preventing damage from excessive gassing: Battery-safe mode
To shorten charging time, the aim is to use the highest possible charging current in conjunction with a high constant voltage. However, to avoid excessive gassing towards the end of the constant current phase, the Skylla-i limits the rate of voltage increase after the gassing voltage has been reached.

Suitable for Lithium-ion batteries (LiFePo4)
Simple on/off control can be implemented by connecting a relay or an 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 galvanically isolated CAN bus port.

Two outputs for charging two batteries
The chargers have two isolated outputs. The second output is intended for charging a starter battery. It has a slightly lower output voltage and is limited to 4 A.

Battery voltage sensor
To compensate for voltage losses due to cable resistance, the Skylla-i has a voltage sensor in the charging circuit, so the battery always receives the correct charging current.
