Supplementary batteries for the power support in your caravan

Our high-quality supplementary batteries provide your caravan with the necessary additional energy. With our deep cycle batteries you can enjoy your holiday regardless of other power supplies.

Supply batteries ensure the supply of all electrical consumers in the caravan. These include, for example, TV, coffee machine, laptops and others. The choice of technology depends on where the battery is installed.

Use one of our chargers to charge your caravan battery.

The correct connection

Parallel battery connection
Often one battery is not enough to cover the power requirement or a large battery does not fit into your motorhome due to its dimensions. Then you can connect several batteries with battery cables in a parallel connection to increase the capacity. In doing so, the two positive poles are connected together and the negative poles.

Series battery connection
If your caravan is designed for 24V, you must connect two 12V batteries in series. When connecting in series, the positive terminal of one battery is connected to the negative terminal of the other battery.

Series and parallel battery connection
Both types of connection can also be combined if more than 4 batteries are used. This allows both the capacity and the voltage to be increased.
