The Victron 20A 12V Blue Smart IP22 mains battery charger offers a cutting-edge solution for charging 12V batteries or battery banks from a mains power source (220-240V AC). Renowned for its efficiency, the charger boasts a remarkable 93% efficiency rate, coupled with an adaptive automatic 6-stage charging process to ensure rapid and efficient charging. With built-in Bluetooth connectivity, users can conveniently monitor and manage the charging process through any Bluetooth-enabled device using the VictronConnect App. This versatile charger is compatible with both Lithium batteries, featuring a dedicated charging mode, and standard Lead Acid batteries including AGM, Gel, and Wet cell types. It supports charging of single or multiple 12V batteries connected in parallel, provided they are of the same type, capacity, and age.  

Key Features:

• Safe Unattended Charging: Integrated safety features protect against DC short circuit, overheating, overcharging, and reverse polarity, allowing the charger to be permanently connected for automatic charging.
• Adaptive Battery Management: Automatically optimises the charging process based on battery usage, reducing corrosion by limiting time in the absorption stage.
• Continued Charging During Use: Maintains the charge even while energy is drawn from the battery, ensuring uninterrupted power supply.
• Power Supply Function: Can provide direct power to a 12V load without a connected battery.
• Dead Battery Recovery: Attempts to recharge deeply-discharged batteries starting from 0V, resuming normal charging once sufficient voltage is reached.
• Silent Night Mode: Reduces output current to 50% for quiet operation in night or low mode.
• Storage Mode: Prevents battery aging by minimising gassing and corrosion, activating after 24 hours of non-use.
• Bluetooth Connectivity: Allows remote programming, monitoring, and updates via the VictronConnect App.
• Inbuilt Temperature Sensor: Adjusts charging parameters based on ambient temperature for lead-acid batteries.
• Charging Status LEDs: Displays the current charging stage and mode with 9 LED indicators.
