Victron Skylla-i 24/100 (1+1) 230V Battery Charger 100A 24V (1+1)

Victron Skylla-i Battery Charger for 24V Batteries

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

Less maintenance and aging during battery 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 raised back to the constant voltage threshold to 'refresh' the battery. This achieves a type of equalization charge that prevents electrolyte stratification and sulfation – the two main reasons for premature battery failure.

Robust
The epoxy powder-coated aluminum housing with drip protection and stainless steel brackets withstand even the harshest environmental conditions: heat, humidity, and salty air. An acrylic coating optimally protects the circuit boards from corrosion.
Temperature sensors ensure that the power components always operate within the specified limits. In extreme environmental conditions, the output current is automatically reduced if necessary.

Preventing damage from excessive gassing: battery-friendly mode
To shorten charging time, the aim is to achieve 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)
A simple on/off control can be implemented by connecting a relay or an optocoupler output with an open collector from a Li-Ion BMS to the remote control port of the charger.
Alternatively, voltage and current can be fully controlled by establishing a connection 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.
