The Victron Energy Blue Smart IP65 Charger is the new professional battery charger with built-in Bluetooth. The Blue Smart IP65 Charger can be used on devices in your workshop and on motor vehicles, such as classic cars, motorbikes, boats, and camper vans. The battery is charged, smartly, to perfect condition. The seven-step charging algorithm gets the best out of your battery. The charger gives the battery the power it needs, maintains its health, and ensures better performance and a longer life. Unlike other brands, the Blue Smart IP65 Charger will attempt to recharge a deeply discharged battery by force-feeding it with a low current. Normal charging will then be resumed as soon as there is sufficient voltage across the battery terminals. Check the status of your battery remotely. The Blue Smart IP65 Charger is equipped with built-in Bluetooth, so the status of the charger and the battery can be checked on a smartphone, tablet, or laptop. All settings of the charger can be configured with the VictronConnect app. The charger comes with both crocodile clips and M8 eyelets, making it easy to connect to the battery.
