Victron 25A Buck-Boost DC/DC Converter

Stable charging and correct voltage – even with varying input.

The Victron 25A Buck-Boost DC/DC converter is an intelligent charger that ensures optimal charging of your batteries – regardless of whether the generator voltage is too high or too low. It automatically regulates the voltage (buck/boost), so the battery always receives the correct charging voltage.

It is ideal for smaller installations and modern vehicles with intelligent generators (Euro 5/6), where the voltage can vary and make ordinary charging solutions inefficient.
