The Victron Blue Smart IP22 12/20(1) is a single-output 12V, 20A battery charger built for trade and marine use. It plugs into a 230V supply via a CEE 7/7 (Schuko/French) connector and has Bluetooth built in, so it can be monitored and adjusted through the Victron Connect app without any extra dongle or laptop.

Key features

• Output, 12V at 20A charge current, suited to lead-acid and lithium battery banks up to approximately 200Ah.
• Bluetooth built in, connects to the Victron Connect app for monitoring, charge history and settings.
• Ingress protection, IP22, suitable for indoor and sheltered outdoor mounting.
• Outputs, single (1) output configuration, one dedicated charge circuit.
• Mains plug, CEE 7/7 (Schuko/French) for direct 230V AC connection.
• Charge algorithm, adaptive seven-stage bulk, absorption, float and storage phases with automatic battery type detection.

Product overview

A microprocessor watches the battery's response during the bulk phase and adjusts the absorption time accordingly, which limits overcharging on batteries that are only partially discharged. Fixed-time chargers tend to overcharge in this scenario, and that shortens battery life over time. Storage mode then holds the battery at a suitable voltage during long idle periods without continuous gassing.

Battery chemistry is selectable in the app: gel, AGM, flooded lead-acid and LiFePO4 are all supported. The IP22 rating allows fitting in an engine bay, locker or sheltered outbuilding, but the unit should not be exposed to direct rain or submersion. Victron also makes two-output and three-output versions of this charger for multi-bank setups; this listing is the single-output variant.

Applications

• Charging and maintaining 12V lead-acid or LiFePO4 battery banks in marine vessels, motorhomes and caravans.
• Workshop battery maintenance for automotive, agricultural and plant machinery batteries.
• Off-grid cabin or outbuilding battery charging where a 230V AC supply is available.
• Standby and backup power systems needing regular conditioning and storage maintenance.

What's in the box

• Victron Blue Smart IP22 12/20(1) charger unit
• CEE 7/7 mains cable (230V)
• DC output cable with ring terminals

Installation notes

Connect to a 230V AC supply via the supplied CEE 7/7 plug, protected by an appropriately rated fuse or MCB. DC connections go to the battery terminals with correct polarity; the unit has reverse polarity protection. For lithium batteries, check the BMS is compatible with the charger's lithium profile first. Allow ventilation around the unit in enclosed spaces, and have a qualified auto-electrician or marine electrician carry out any permanent vehicle or vessel wiring.
