Victron Blue Smart IP67 Charger - 12V/25A (si)

The seven-step charging algorithm gets the best out of your battery. The charger gives the battery the power it needs, maintains its health, ensures better performance and a longer life. Unlike other brands, the Blue Smart IP67 Charger Waterproof 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. 

Blue Smart IP67 Charger Waterproof 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.
