Victron Energy Skylla-i Battery Charger 24V

Skylla-i chargers, Canbus Nmea2000 compatible
Modern and powerful marine battery chargers that can withstand severe adverse operating conditions such as heat, humidity and marine climate.

The aluminum case with an epoxy powder coating is able to withstand harsh adverse conditions, the printed circuit boards are protected by an acrylic coating, which provides maximum protection against corrosion. Temperature sensors always ensure that the power elements operate safely.

Skylla-I (1 + 1) chargers have two isolated outputs. The second output is limited by 4A current of charge and reduced output voltage. The output is designed to charge the motor starter battery.

Skylla-I (3): three full current outputs for charging 3 battery banks

The Skylla-I (3) charger has three isolated outputs. All outputs can produce a full rated charge output current (if used separately).

Synchronize for Parallel Work
Several devices can be synchronized to each other via the CAN bus for synchronous parallel operation. This is achieved by simply connecting the chargers by cables to the UTP RJ45 connector (see operating manual).

Correct charge for lead-acid batteries: variable absorption time
When a short discharge occurs, the absorption phase time will be short to prevent recharging of the battery. After deep discharge, the absorption phase time is automatically increased to achieve full charge.

Prevent damage due to excessive gassing: BatterySafe mode
If a high charging current is selected for fast battery charging, combined with a high absorption voltage, then Skylla-I will prevent damage to the battery due to excessive gas emission by automatically limiting the rate of voltage rise after reaching the voltage on the battery, at which gases can be generated.

Storage mode
The storage mode is initialized when the battery has not been discharged for 24 hours. In the storage mode, the floating charge voltage is reduced to 2,2V/cell (26,4V for battery 24V) to minimize the release of gases and corrosion of positive plates. Once a week, the voltage rises back to the absorption level to "level up" the battery. This feature prevents electrolyte delamination and plate sulfation, the main causes of early battery failure.

Extended Battery Life: Temperature Compensation
Skylla-i chargers come with a battery temperature sensor. The charging voltage automatically decreases as the battery temperature increases. This feature is particularly useful for sealed lead-acid batteries.

Using as a Power Supply
As a result of a completely stabilized output voltage, chargers can be used as a DC source, for example, when the battery is not available.

Correct Charge Voltage: Sensor Input Battery Voltage
In order to compensate for voltage loss due to cable resistance, Skylla-i chargers have an input for sensor sensing of battery voltage. This allows the charger to adjust the output voltage so that the battery always receives the correct charge voltage.

Charge and control of Li-Ion (LiFePO4) battery
Simple charge control (on-off) can be carried out by connecting the contacts of a relay or optron with an open output collector remote control of the BMS Li-Ion battery to the port of the charger. In addition, full voltage and current control can be carried out by connecting the BMS to a galvanically isolated CAN port.
