The Votronic charging converters ensure optimised and quick charging of the Motorhome supply battery by the dynamo during driving. In contrast to simple cutoff relays, the charging voltage will be raised to the value, which is required for full charging of the corresponding battery type and which is prescribed by the battery manufacturers. So, the full charging current is available, and the battery is charged with considerable current rates within short time.

Long charging cables and losses, as well as voltage fluctuations at the dynamo are neatly compensated. Charging converters with different input and output voltage rates (12V / 24V or 24 V/12 V) allow simple charging of a second battery, even without installation of a second dynamo.

Thus, the charging converter ensures the known high-quality battery charging of the VOTRONIC chargers also during driving. Due to the intelligent microprocessor charging control with characteristic lines of charging „IU1oU2oU3“ and dynamic charging time calculation an automatic, quick and gentle full charging is ensured, as well as subsequent trickle charge of the connected batteries from any charging state. At the same time, simultaneous supply of consumers in parallel to the supply battery is ensured.

The charging converters excel by their compact design, low weight (high-frequency switch mode technology), powerfully dimensioned power components and consequently full charging capacity, even with long charging cables or strong voltage fluctuations at the starter battery (EURO Standard 6, 6 + plus vehicles). Pilot lamps always inform about the operating state of the unit. The connection of a Remote Control, plug-in type, is provided and can easily be realised.


Charging of modern Lithium batteries with devices which are used for ordinary batteries in lead-acid-technology (incl. Gel or AGM) will cause probably, that the advantages of this new technology (capacity, number or cycles etc.) is not fully usable.

If higher capacity is required, operation of two units in parallel operation is possible.
