The Victron Blue Smart IP22 12/15(3) is a mains-powered battery charger for trade and professional use. It delivers 15A of charge current to 12V battery banks across three simultaneous outputs, with built-in Bluetooth for monitoring and configuration through the VictronConnect app.

Key features

• Charge current, 15A at 12V across three independent outputs, so up to three batteries can charge at once.
• Connectivity, built-in Bluetooth for wireless monitoring and setup via VictronConnect on iOS and Android.
• Protection rating, IP22, suited to sheltered indoor or enclosed spaces rather than exposed outdoor use.
• Mains plug, CEE 7/7 (Schuko/French standard) for direct connection to a 230V AC supply.
• Charging algorithm, adaptive multi-stage process covering bulk, absorption and float stages.
• Battery compatibility, works with flooded, gel, AGM and lithium (LiFePO4) chemistries with appropriate configuration.

How it charges

During bulk charge the unit delivers the full 15A to bring the battery up to voltage. Absorption then holds voltage steady while current tapers off, followed by a float stage that keeps the battery at a safe standby level. The process runs automatically, though it can be adjusted in VictronConnect if a specific battery profile is needed. A storage mode reduces float voltage to limit degradation during long standby periods, and temperature-compensated charging is available with an optional temperature sensor.

Applications

The three-output design suits workshops and vehicle fleets where several batteries need attention at once, cutting the need for separate chargers. It also fits marine installations, motorhomes, off-grid cabins and seasonal storage for boats or motorcycles left on standby. The Bluetooth link gives a live view of voltage, current and charge state, useful for diagnostics and commissioning on-site.

Installation notes

Connect directly to a 230V AC mains supply using the supplied CEE 7/7 plug, in a dry, ventilated location away from moisture. Confirm the correct battery profile in VictronConnect before charging lithium (LiFePO4) batteries. For permanent installation in a vehicle, vessel or off-grid system, a qualified electrician is recommended.
