The Victron Blue Smart IP65s Charger 12/4(1) is a compact 12V charger delivering 4A output, built for permanent connection to a battery in damp or exposed locations. It suits installers and owners of boats, caravans and vehicles who want a sealed charger with phone-based monitoring rather than a separate display.

Key features of the Victron Blue Smart charger

• Enclosure, IP65 rated, protects against dust and water jets for damp or exposed mounting locations.
• Bluetooth monitoring, built-in Bluetooth links to the VictronConnect app for charge status and settings.
• Charge algorithm, adaptive, multi-stage charging protects battery life and shortens charge times versus constant-voltage charging.
• Battery chemistries, supports lead-acid, gel, AGM and lithium iron phosphate, selectable in the app.
• Standby draw, low power consumption once the battery is fully charged and the unit stays connected.
• Mains plug, supplied with a UK BS 1363 plug fitted for direct use on a UK socket.

Product overview

Output is 12V at 4A, sized for smaller battery banks such as those on motorbikes, small boats, caravans and backup systems. The IP65 rating allows mounting in engine bays or battery compartments exposed to moisture and dust, without an extra enclosure.

The multi-stage algorithm moves through bulk, absorption and float stages, adjusting current and voltage as the battery charges. This reduces the risk of overcharging and lets the unit stay connected long term without supervision. Bluetooth means status, charge profile and history are all visible from a phone, with no need to open the unit or wire in a separate monitor.

Applications

• Charging and maintaining starter or leisure batteries on small boats and RIBs
• Trickle charging motorcycle, quad or garden equipment batteries
• Standby charging for caravan and campervan battery systems
• Maintaining backup batteries in alarm, gate or access control systems
