The Victron Skylla-i 24-80 (1+1) charger has 2 isolated outputs. The second output, limited to approximately 4 A, and with a slightly lower output voltage, is intended for fully charging a starter battery.<\/p>\n
The Skylla-i (3) has 3 isolated outputs. All outputs can supply the full rated output current.<\/p>\n
Aluminium epoxy powder coated housings, with drip shield and stainless steel hardware, withstand the rigours of the harshest environments: heat, humidity and salt air, while the printed circuit boards are protected by an acrylic coating for maximum corrosion resistance.<\/p>\n
Temperature sensors ensure that the electrical components will always operate within the specified limits, automatically reducing the output current if necessary in extreme environmental conditions.<\/p>\n
In addition to the CAN-bus interface (NMEA 2000), a rotary switch, DIP switches and potentiometers are available to adapt the charging algorithm to a particular battery and its conditions of use.<\/p>\n
Several chargers can be synchronised with the CAN-bus interface. To do so, simply connect the chargers with RJ45 UTP cables<\/a>. Operation: Two-output and three-output chargers cannot be connected in parallel. Please refer to the manual for more information.<\/p>\n When the discharge is shallow, the absorption phase is shortened to avoid overcharging the battery. After a deep discharge, the absorption charging time is automatically increased to ensure that the battery is fully recharged.<\/p>\n If a combination of high charging current and high absorption voltage has been chosen to charge a battery quickly, Skylla-i will prevent damage from over-gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached.<\/p>\n The storage mode is activated when the battery has not been discharged for 24 hours. In storage mode, the float voltage is reduced to 2.2 V\/cell (26.4 V for 24 V batteries) to reduce gassing and corrosion of the positive plates. Once a week, the voltage is brought back up to absorption level to \"freshen\" the battery. This function prevents electrolyte stratification and sulphation, the main causes of battery failure.<\/p>\n All Skylla-i chargers come with a battery temperature sensor. When connected, the charging voltage will automatically decrease as the battery temperature increases. This function is especially recommended for sealed lead-acid batteries and\/or when large temperature fluctuations are expected in the battery.<\/p>\n To compensate for voltage losses due to cable resistance, the Victron Skylla-i 24-80 (1+1) Charger has a voltage probe function so that the battery always receives the correct charging voltage.<\/p>\n The chargers also support DC power.<\/p>\n Thanks to its perfectly stabilised voltage output, the Skylla-i can be used as a power supply in cases where batteries or compensating capacitors are not available.<\/p>\n Simple on\/off control can be implemented by connecting a relay or optocoupler with open collector output from a Li-Ion BMS to the remote control port of the charger. Full voltage and current control is also possible by connecting to the galvanically isolated CAN-bus port.<\/p>\nThe right amount of charge for a lead-acid battery: variable absorption time<\/h2>\n
