Victron Blue Smart Charger 12V 10A Water, dust and chemical resistant Seven step smart charge algorithm Recovery of fully discharged 'dead' batteries Automatic power supply function Servere cold performance: down to -30°C Several other battery life enhancing features Low power mode to charge smaller batteries Li-ion battery mode Setup and configure, readout of voltage and current by Bluetooth Smart Ultra high efficiency “green” battery charger With up to 95% efficiency, these chargers generate up to four times less heat when compared to the industry standard. And once the battery is fully charged, power consumption reduces to 0.5 watt, some five to ten times better than the industry standard. Temperature compensated charging The optimal charge voltage of a lead-acid battery varies inversely with temperature. The Blue Smart IP65 Charger measures ambient temperature during the test phase and compensates for tempera - ture during the charge process. The temperature is measured again when the charger is in low current mode during float or storage. Special settings for a cold or hot environment are therefore not needed. Li-ion battery mode The Blue Smart Charge r uses a specific charging algorithm for Li-ion (LiFePO4) batteries, with automatic Li-ion under voltage protection reset. The VictronConnect app Setup, readout and configure your Blue Smart IP65 Charger via your smartphone. You can display the status of your charger and battery and even control the functions of your charger using the VictronConnect app. On your screen the readout of voltage and current is default available.
