The Victron Blue Smart IP65 Charger 24/13 is a professional 24 V, 13 A battery charger with built-in Bluetooth, suitable for lithium as well as conventional batteries. It is a water, dust and chemical resistant unit designed for workshop use and for motor vehicles such as classic cars, motorbikes, boats and camper vans. A seven-step smart charge algorithm gives the battery exactly what it needs at each stage, maintaining its health for stronger performance and a longer life, and a reconditioning function can recover fully discharged batteries. Temperature-compensated charging keeps performance consistent, with severe cold operation down to -30 degrees C and a dedicated low power mode for smaller batteries. As a high-efficiency charger it reaches up to 95 per cent efficiency, and an automatic power supply function lets it run as a stable DC source. Built-in Bluetooth lets you set up, monitor and read voltage and current through the VictronConnect app on a phone, tablet or laptop. Cabling and quick-fit connectors are included, with both crocodile clips and M8 eyelets so it can be connected quickly or left permanently in place.
