The Victron Blue Smart IP22 Charger 12/30(3) is a three-output 30A battery charger for 12V lead-acid and lithium battery banks. It plugs straight into a UK BS 1363 socket and is set up and monitored through the VictronConnect app over Bluetooth, making it suited to installers, marine engineers and off-grid system builders who need one charger to manage several battery banks at once.

Key features of the Victron Blue Smart charger

• Charge current, 30A total, split across three independent outputs so up to three battery banks charge at the same time.
• Bluetooth control, configuration, monitoring and fault diagnostics through VictronConnect on iOS and Android.
• Enclosure rating, IP22, protected against solids over 12.5mm and direct water spray, suited to engine rooms and sheltered outdoor spots.
• Battery compatibility, works with AGM, Gel, flooded lead-acid and LiFePO4 12V batteries.
• Charge algorithm, adaptive seven-stage profile: bulk, absorption, float, storage, equalisation, recondition and temperature-compensated charging.
• Mains plug, UK BS 1363 fitted as standard, no adaptor needed.

Where it's used

The three outputs make this practical on boats, where a starter battery, a domestic bank and a bow thruster battery each need their own charge management. Motorhomes and caravans with multiple 12V banks suit it just as well, and it's equally at home in off-grid cabins, workshops or vehicle fleets where several batteries need periodic maintenance from a single mains-fed charger.

Adaptive charging and remote monitoring

The charge algorithm adjusts absorption time to how discharged the battery was at the start of the cycle, so a deeply drained battery gets a longer absorption phase while a lightly used one moves to float sooner. VictronConnect gives access to absorption voltage, float voltage and equalisation settings, plus charge history and fault logs, straight from a phone rather than a laptop or separate interface cable. A storage mode also drops the float voltage after 24 hours to reduce wear during long-term standby.
