Victron Blue Smart IP22 12/20(3) Charger 230V UK | BPC122043022

The Victron Blue Smart IP22 12/20(3) is a mains-powered battery charger with Bluetooth built in, made for charging multiple batteries from one unit. It runs from a standard UK BS 1363 plug and delivers 20A across three independently controlled outputs, which suits workshops, vehicle fleets and marine setups.

Key features

• Charge current, 20A total, shared across three separate output connections so up to three batteries can charge at once.
• Bluetooth monitoring, built-in connectivity for full monitoring and configuration through the VictronConnect app on iOS and Android.
• Enclosure rating, IP22, protecting against finger contact and dripping water, suited to sheltered indoor or covered outdoor spaces.
• Charge algorithm, adaptive seven-stage process covering bulk, absorption, float, storage, equalisation and recondition phases.
• Battery compatibility, lead-acid types including GEL, AGM, AGM Spiral, Tubular Plate and flooded/wet cell, plus a lithium LiFePO4 profile.
• Storage mode, reduces float voltage automatically after 24 hours to limit battery degradation in long-term standby.

How it charges

The adaptive algorithm adjusts absorption time based on the battery's response during the bulk phase rather than applying a fixed period regardless of condition. Batteries that are cycled regularly avoid unnecessary overcharging, while deeply discharged batteries get extended absorption to reach a full charge. Settings for charge profile, battery type and absorption voltage are configured through VictronConnect and stay in memory after the unit is power cycled.

Across the three outputs, the 20A charge current is shared between whichever ones are connected, which works well where several batteries of different sizes need attention together.

Applications

• Workshop or garage maintenance of multiple vehicle or equipment batteries.
• Marine and narrowboat installations in covered engine bays or ventilated below-deck compartments.
• Motorhome and caravan habitation battery charging from a mains hookup.
• Light commercial fleet maintenance between shifts.
• Off-grid or backup systems with periodic mains access for battery top-up.

Installation notes

Connects directly to a 230V AC mains socket via the fitted UK plug, no hardwiring needed. Site it somewhere sheltered from direct rain with good ventilation, since the unit generates heat while charging. Confirm battery chemistry and set the matching charge profile in VictronConnect before first use, and for LiFePO4 batteries check the BMS is compatible with the lithium profile. Vehicle or marine wiring should follow the relevant standards and be carried out by someone familiar with 12V DC systems.
