A powerful, waterproof and intelligent battery charger with a 7-stage adaptive charge algorithm. Suitable for a wide range of battery types and chemistries, including a dedicated lithium-ion charge algorithm. The battery charger has one full rated output, together with an isolated 3A trickle charge output for a starter battery.

The IP65 waterproof rating makes this charger perfect for marine, mobile and industrial applications as it will easily withstand adverse environments. Circuit boards are protected with an acrylic coating for maximum corrosion and temperature sensors ensure that power components will always operate within specified limits, if needed by automatic reduction of output under extreme environmental conditions.

An LCD display is great for status monitoring and also enables you to easily adapt the charge algorithm to a particular battery and its conditions of use.

Several chargers can be connected in parallel and synchronised with the help of the CAN-bus interface. This is achieved by simply interconnecting the chargers with RJ45 UTP-cables. When only shallow discharges occur, the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge, the absorption is increased to make sure that the battery is completely recharged. In order to quickly charge a battery, Victron have opted for a high charge current with a high absorption voltage. Skylla will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached.

Skylla also has a battery temperature sensor, When conencted, charge voltage will automatically decrease when the battery temperature increases. This is especially useful for sealed lead-acid batteries and/or when important fluctuations of battery temperature are expected.

The IP65 battery charger has a storage mode that kicks in whenever the battery has not been subjected to discharge over a 24 hour period. In the storage mode, float voltage is reduced to minimise gassing and corrosion of the positive plates. Once a week, the voltage is raised back to the absorptio level to refresh the battery. This feature prevents stratification of the electrolyte and sulphation, a major cause of early battery failure.

As a result of Skylla's excellent control circuit, the marine battery charger can be used as a power supply with perfectly stabilised output voltage if batteries or large buffer capacitors are not available. A simple charger ON/OFF control can be implemented by connecting a relay or open connector onto coupler output from a lithium ion BMS to the remote control port of the charger. Alternatively complete control of voltage and current can be achieved by connecting to the CAN-bus port.
