Victron 20A 12V Blue Smart IP22 Charger with Bluetooth | 4Boats

Compact Victron 20 A 12 V Blue Smart IP22 mains charger with Bluetooth for safe unattended charging of 12 V lead‑acid (AGM, Gel, Wet) and lithium batteries.

• Safe unattended charging — inbuilt protections against DC short circuit, overheating, overcharging and reverse polarity; suitable for permanent connection.
• Adaptive 6‑stage battery management — automatically adapts and optimises charging to battery use, reducing corrosion and time in absorption when appropriate.
• Continued charging during use — maintains charge while energy is being drawn from the battery.
• Power supply function — can directly supply a 12 V load even when no battery is connected.
• Dead battery recovery — will attempt to recharge deeply discharged batteries, starting from 0 V at low current and resuming full charging when voltage allows.
• Silent night mode & storage mode — night/low mode reduces output current to 10 A for quiet operation; storage mode prevents ageing and helps reduce sulphation.
• Bluetooth connectivity — remote monitoring and programming via the VictronConnect app; inbuilt temperature sensor measures ambient temperature and applies automatic temperature compensation.
• Performance & compatibility — AC input: 180–265 V; DC output 20 A (normal) / 10 A (night); output voltage 12 V; minimum battery capacity (normal): Lead‑acid 67 Ah, Lithium 40 Ah; low mode minimum: Lead‑acid 33 Ah, Lithium 20 Ah; absorption 14.2–14.7 V, float 13.5–13.8 V; minimum battery voltage: starts charging at 0 V; efficiency 93%; standby power consumption: 0.5 W (typical); temperature compensation: -16 mV/°C (12 V system; -4 mV/°C per cell).
• Installation & indicators — 9 LEDs indicate charging stage (night, bulk, absorption, float etc.), IP22 for indoor use, humidity: max 95% (non‑condensing), supplied with UK 3‑pin plug; dimensions 235 x 108 x 65 mm (9.25 x 4.25 x 2.56 in), weight 1.3 kg (2.9 lb), operating range −20°C to +50°C (−4°F to 122°F).

Compatible with single 12 V batteries or multiple 12 V batteries in parallel (batteries must be same type, capacity and age). User manual and data sheet available for download.
