Compact 15 A 12 V mains battery charger with Bluetooth for remote monitoring and adaptive 7‑stage charging suitable for lithium and lead‑acid batteries.

• Safe unattended charging: inbuilt protections against DC short circuit, overheating, overcharging and reverse polarity; suitable for permanent connection.
• Adaptive battery management: automatic 7‑stage algorithm optimises charging and reduces time in absorption to limit corrosion and extend battery life.
• Continued charging during use & power‑supply function: maintains charge while a load is drawing power and can power a 12 V load even with no battery connected.
• Dead battery recovery: attempts recharge from deeply discharged batteries (starts charging at 0 V) and resumes normal charging once voltage is sufficient.
• Silent night mode & storage mode: 'night' or 'low' mode reduces output to a maximum of 50% for quiet operation; storage mode prevents battery ageing and reduces sulphation.
• Bluetooth connectivity & inbuilt temperature sensor: program settings and monitor via the VictronConnect app; automatic temperature compensation (16 mV/°C) improves charging accuracy. Adjust charging current and battery type in the VictronConnect app.
• Charging status indicators: 11 LEDs show current charging stage (night, bulk, absorption, float and storage) and operational status.
• Compatibility: suitable for lithium batteries (dedicated lithium mode) and lead‑acid types including AGM, Gel and Wet cell; batteries in parallel must be same type, capacity and age.
• Specifications: Operating AC 180–265 V; DC output 15 A (normal) / 7.5 A (night/low); DC output voltage 12 V; absorption 14.2–14.7 V; float 13.5–13.8 V; efficiency 93%; standby 0.5 W; IP22 (indoor); dimensions 235 x 108 x 65 mm (9.25 x 4.25 x 2.56 in); weight 1.3 kg (2.9 lb); operating temp -20°C to 50°C (-4°F to 122°F); humidity (non‑condensing): max 95%; minimum battery capacity 30 Ah (normal) / 15 Ah (night); temperature compensation 16 mV/°C; warranty: 5 years.

For best results use indoors (IP22) and follow the user manual. Suitable for single 12 V batteries or identical batteries in parallel; select the correct battery type in the app before first charge.
