Highly impervious to water, dust and chemicals Use in extreme cold: down to -30°C (-22°F) Optimal battery charge management for long battery life Adaptation of the charge for over-discharged batteries Simple and quick connection Low power mode for smaller batteries Lithium-Ion battery mode Setting, updating, reading of voltage and current measurements via Bluetooth Smart This is the new Blue Smart IP67 battery charger. This Bluetooth equipped charger will be able to adapt too many applications, for individuals (car, camper vans) as well as for professionals (workshop devices). Its new algorithm ensures a better exploitation of the battery. Charging and discharging are optimized to keep the battery in good condition, thus extending its life. All this while guaranteeing good performance.The Blue Smart IP67 has the capability to recharge a deeply discharged battery. The charger will then use a low charging current to restore the battery to working order if possible, and then automatically switch to a normal charge.The VictronConnect application and the Bluetooth function of the charger provide real-time information on the status of the battery and charger from a phone, tablet or laptop.
