The Victron Blue Smart IP22 24/16(3) is a mains-powered battery charger for 24V battery banks, delivering up to 16A of charge current across three separate outputs. It suits workshops, vehicles, marine settings and off-grid setups where several batteries need charging from one unit. Bluetooth is built in, so monitoring and configuration happen through the VictronConnect app with no extra hardware needed.

Key features of this victron blue smart charger

• Charge current, 16A maximum for 24V battery systems.
• Outputs, three independent connections sharing the total 16A capacity.
• Bluetooth, built in as standard, with configuration and monitoring via VictronConnect on iOS or Android.
• Ingress protection, IP22, suited to sheltered indoor environments with some moisture exposure.
• Mains plug, CEE 7/7 fitted as standard for 230V AC supply.
• Battery chemistries, flooded, gel, AGM and lithium (LiFePO4), with selectable charge profiles.

Product overview

The charger runs a multi-stage adaptive algorithm rather than a fixed time cycle. A discharged battery gets a controlled bulk charge, then absorption at the correct voltage, then a float phase that holds it at full capacity without overcharging. This tends to extend service life against simpler constant-voltage designs.

All three outputs draw from the same 16A total, so current is split across whatever batteries are connected. That makes the unit useful in dual-battery vehicle installations or small parallel battery banks. Storage mode keeps batteries maintained through long periods without use, and an optional temperature sensor allows automatic compensation.

VictronConnect lets an installer select the battery type, set charge voltage, and check real-time or historical charge data over Bluetooth, with no separate dongle required.

Applications

• 24V battery banks in campervans, motorhomes and commercial vehicles with dual or split systems.
• Workshop maintenance for 24V lead-acid or lithium packs.
• Off-grid cabins with periodic mains access for battery top-up.
• Marine use in sheltered or below-deck locations where IP22 is adequate.
• Seasonal charging for boats, plant equipment and backup power systems.

Installation notes

Connect to a 230V AC mains supply via the fitted CEE 7/7 plug, on a circuit correctly rated and protected with a fuse or MCB. DC connections to the battery terminals need correctly rated cable and inline fusing on the positive lead. Confirm the battery chemistry and voltage match the selected charge profile before use, and ensure ventilation and IP22 suitability for the installation environment. Consult a qualified electrician or auto-electrician if unsure.
