Victron Energy Skylla-IP65 Battery Charger (12V 70A / 24V 35A)

The Skylla‑IP65 delivers lab‑grade charging in a rugged, corrosion‑resistant enclosure that shrugs off heat, humidity, and salt air. Its 7‑stage adaptive algorithm charges fast, protects your batteries, and extends service life—charging lead-acid, AGM/Gel banks and LiFePO₄ batteries, with VE.Can (NMEA 2000) networking for full system integration.

Why boat owners choose Skylla‑IP65

• Serious power, compact form: Available in 12 V / 70 A and 24 V / 35 A, each in a (1+1) or (3) output configuration.

• Flexible multi‑bank charging: Choose (1+1) — a full-rated house output plus an isolated 3 A starter-battery trickle — or (3), three isolated outputs that share the charger's full rated current (combined output up to 70 A at 12 V / 35 A at 24 V), intelligently distributed across the connected banks.

• Marine‑proof build: IP65 steel chassis (blue RAL 5012) with epoxy powder-coat, acrylic-coated PCBs, and forced-air cooling for reliability in harsh environments.

• Smarter battery care: 7‑stage adaptive charging with BatterySafe and Storage modes, plus temperature compensation and remote voltage sense for precise regulation right at the battery.

• Lithium‑ready: Dedicated 3-stage LiFePO₄ profile with simple BMS on/off via the remote port — or full voltage/current control over VE.Can.

• Network & scale: VE.Can (NMEA 2000) interface for GX/system integration and synchronised parallel operation (interconnect chargers with RJ45 UTP cables) when you need more current.

• At‑a‑glance control: Front-panel LCD for status monitoring and quick setup.

• Universal shore power: 90–265 VAC, 45–65 Hz with power-factor correction — ideal for global cruising and small gensets.

• Power supply mode: Works as a stabilized DC power supply when batteries are offline.

• Integration‑ready: Alarm relay and remote on/off for advanced systems.

Technical snapshot

• Charge algorithm: 7-stage adaptive (lead-acid) + 3-stage LiFePO₄

• Outputs: (1+1) = 1 × full-rated + 3 A isolated starter; (3) = 3 × isolated outputs sharing the full rated current (70 A total at 12 V / 35 A total at 24 V)

• Charge voltages: absorption 14.4 V / 28.8 V, float 13.8 V / 27.6 V, storage 13.2 V / 26.4 V

• Recommended bank size: ~350–700 Ah (12 V), 150–350 Ah (24 V)

• AC input: 90–265 VAC, 45–65 Hz; PF ≈ 0.98 (≈12 A max @ 100 VAC)

• Operating temp: −4 to 140 °F (full output up to 104 °F; output reduces to 60% at 122 °F and 40% at 140 °F)

• Protection: reverse-polarity (fuse), output short-circuit, over-temperature

• Warranty: 5-year manufacturer's warranty

Ideal applications

• Blue-water cruisers and expedition yachts

• Commercial vessels, workboats, and patrol craft

• RVs/specialty vehicles and off-grid industrial systems that demand sealed, high-output charging

What's in the box

Installation notes

Mount in a ventilated area to support forced cooling and allow for thermal derating in hot engine rooms. Use appropriately sized cabling and fusing, and land the voltage-sense leads at the battery terminals for best accuracy. For lithium banks, wire BMS control to the remote on/off or manage over VE.Can, and program charge parameters to your battery maker's spec.

Blue Marine tip: Pair the Skylla-IP65 with a Victron GX device (over VE.Can) for seamless system integration, and add a SmartShunt or BMV-712 for accurate state-of-charge and Bluetooth monitoring — an ideal foundation for lithium conversions and hybrid shore/generator setups.
