The Victron Smart IP43 Charger 24V 25A (1+1 Outputs) is a premium battery charger engineered for applications that require charging both a primary 24V battery bank and a separate starter battery. Delivering up to 25A to the main battery bank while automatically maintaining a second battery with a dedicated 4A output, it's an ideal solution for commercial vehicles, marine vessels, industrial equipment, and off-grid power systems.
Built-in Bluetooth allows you to monitor charging status, configure charging parameters, review charging history, and install firmware updates using the VictronConnect app. The adaptive 6-stage charging algorithm automatically adjusts to battery condition for faster charging and longer battery life, while VE.Smart Networking enables wireless battery voltage and temperature compensation with compatible Victron Smart devices.
