The Victron Skylla-IP65 24/35 is a weatherproof battery charger built for marine, industrial and off-grid installations where a standard indoor unit will not survive the environment. It is IP65 rated, delivers 24V nominal output at 35A continuous charge current, and uses a (1+1) output configuration: one main output for the service bank plus one independent output for a starter or auxiliary battery.

Marine battery charger built for exposed installations

• Enclosure rating, IP65, protected against dust and low-pressure water jets from any direction.
• Output, 24V DC at 35A continuous, with (1+1) dual output for a main bank and a separate starter or auxiliary battery.
• AC input, 120-240V, so the same unit works on UK and European 230V supplies or North American 120V shore power without modification.
• Charge algorithm, adaptive four-stage (bulk, absorption, float, storage) with a temperature sensor input available to adjust charge voltage.
• Monitoring, VE.Direct port for integration with Victron GX devices and the VictronConnect app.
• Battery compatibility, configurable charge profiles for AGM, gel, flooded lead-acid and lithium chemistries.

Applications

The (1+1) topology suits vessels and vehicles that need a service bank charged independently from a starter battery, with the auxiliary output keeping the starter topped up without risk of overcharge. Typical installations include marine vessels on shore power, coaches and motorhomes with 24V systems, off-grid cabins exposed to moisture or dust, industrial plant with 24V battery systems, and backup power in telecoms or security installations where IP-rated hardware is specified.

Monitoring and integration

The VE.Direct interface connects to Victron's Cerbo GX and Venus GX for remote charge status and state-of-charge visibility. A compatible GX device or a smartphone running VictronConnect is required separately.

What's included

• Victron Skylla-IP65 24/35 (1+1) battery charger unit
• Mounting hardware

Installation notes

Fit by a qualified electrician or marine electrical engineer. The AC supply must be correctly fused, with input wiring rated for the charger's maximum input current, and DC output cables sized for 35A continuous current over the relevant cable run. If connecting to a lithium battery, confirm the charge profile matches that chemistry before commissioning.
