Description
The Victron Energy Blue Smart IP65 Charger 24/5 is a Bluetooth-enabled 120V AC smart battery charger delivering 5A of charge current to 24V lead-acid and lithium battery banks from a standard US NEMA 1-15 plug.
Rated IP65 for splash, dust, and chemical resistance, the Blue Smart IP65 24/5 is built for demanding environments including marine vessels, RVs, workshops, and outdoor installations where exposure to moisture and contaminants is a regular concern.
With up to 95% efficiency, the Blue Smart IP65 24/5 generates significantly less heat than conventional chargers while consuming only 0.5W on standby — making it one of the most energy-efficient 24V chargers in its class. Full setup, configuration, and live voltage and current readout are available wirelessly via the VictronConnect app on Apple and Android devices over Bluetooth.
Key Features:
- Seven-Step Smart Charge Algorithm — Executes a full charge cycle through Test, Bulk, Absorption, Float, Storage, Refresh, and optional Recondition stages; the Storage stage actively reduces charge voltage after 48 hours of continuous connection to minimize positive plate corrosion during long-term maintenance charging
- Bluetooth Configuration via VictronConnect — Full charger setup, real-time voltage and current readout, and charge stage monitoring via the VictronConnect app on Apple and Android devices; no additional hardware required
- Li-ion (LiFePO₄) Battery Mode — Dedicated Li-ion charging algorithm with automatic under-voltage protection reset for safe and efficient charging of lithium iron phosphate batteries alongside lead-acid battery types
- Recovery of Fully Discharged Batteries — Initiates low-current recovery charging from 0V, allowing the charger to recognize and revive deeply discharged batteries that most reverse polarity protected chargers would fail to detect
- Low Current Mode for Smaller Batteries — Automatically reduces charge current to 2A in low current mode, making the 24/5 suitable for charging smaller 24V batteries in the 30–80Ah recommended range without risk of overcharge damage
- IP65 Rated Enclosure — Fully splash and dust proof with ignition protection; rated for marine, automotive, and outdoor use; completely fanless and silent with no moving parts and low thermal stress on internal components
The Blue Smart IP65 24/5 measures ambient temperature during the test phase and applies automatic temperature compensation throughout the charge cycle at -32mV/°C for lead-acid batteries, eliminating the need for manual seasonal adjustments in cold or hot environments. The charger delivers full rated 5A output up to 30°C ambient, with output current automatically reducing as temperatures rise toward the 60°C maximum operating limit — protecting the charger without shutting it down. The optional Recondition stage applies a higher-voltage, low-current charge to help reverse sulfation in lead-acid batteries that have been left deeply discharged or insufficiently charged over extended periods.
In automatic power supply mode, the Blue Smart IP65 24/5 can be used as a regulated 24V DC power supply for loads directly connected to the battery terminals, making it a practical dual-purpose tool in workshop and service environments. Included in the box are M8 eyelet connectors and a 2-meter extension cable; optional accessories available separately include battery clamps, fused clamps, fused M6 or M8 eyelets, an Autoplug, a battery indicator panel, a battery indicator eyelet M8, a carry case, a wall mount, and a rubber bumper.
