Charger Victron Energy Blue Power IP67 12V 25A – waterproof battery charger for 12 V systems

The Victron Energy Blue Power IP67 12V 25A is a waterproof battery charger for 12 V systems that supplies up to 25 A of charging current. Designed for use in marine, automotive and off-grid applications, this charger supports charging of 12 V lead‑acid batteries and other compatible battery types. Its IP67-rated enclosure protects against dust ingress and temporary immersion in water, enabling installation in exposed or harsh environments where moisture and dirt are a concern.

Advantages

This charger combines a compact, rugged design with smart charging algorithms to deliver reliable, efficient charging while protecting battery life. The waterproof housing and corrosion‑resistant connectors allow safe outdoor and near‑water use. Built‑in protections against overheating, short circuit and reverse polarity reduce the risk of damage during operation. The unit’s stable output and appropriate charge stages help maintain battery health and improve overall system uptime.

Suitable for

• Marine battery charging on boats and yachts
• Automotive and commercial vehicle battery maintenance
• Off‑grid power systems, small solar installations and backup battery banks
• Outdoor equipment and installations exposed to dust and moisture

Key specifications

• Output voltage: 12 V nominal
• Maximum charging current: 25 A
• Ingress protection: IP67 (dust tight and temporary immersion resistant)
• Compatible battery types: 12 V lead‑acid and other compatible 12 V batteries
• Charge control: multi‑stage charging suitable for maintenance and bulk charge
• Operating environment: designed for use in wet and dusty conditions

How to use

Before connecting, ensure the charger is suitable for the battery type and that the battery voltage matches the charger output. Mount the unit in a location where the IP67 protection can be maintained and where ventilation is adequate to avoid heat build‑up. Connect the charger to the battery following the correct polarity and secure all connections. Plug the charger into a suitable AC supply if required by the model variant, then enable charging according to the manufacturer’s instructions. Monitor charging periodically and disconnect when charging is complete or when instructed by battery management systems.

Recommendations

Use this charger for routine maintenance charging and reconditioning cycles rather than as a primary power source under continuous heavy load. For best results, keep terminals clean and check for corrosion regularly. When installing in marine or outdoor environments, ensure cable routing and connectors are protected from mechanical damage and prolonged submersion beyond the rated limits.
