Having the Anderson plug charging system in both your vehicle and caravan wired up correctly to suit the application, will guarantee you get the charge rates specified on the system.

With the uptake of lithium in most modern caravans, this is even more important as the internal resistance of the lithium battery is quite low, it will generally accept any power you give it. This puts stress on the Anderson plugs, cable and fuses in the system. Voltage drop goes through the roof and the result is a disconnecting Dc charger or a melted ‘weak spot’ in the line.

We design all of our Anderson charging systems to suit the power requirements asked by the battery charging system.

An example here is a 50-amp Dc-to-Dc charger located in your caravan some 8-10 meters away from the starter battery. Here, the voltage drops at 12 volt under a massive load are significant. With a correctly designed system, we ensure your caravan batteries charge perfectly and the Dc-to-Dc charger does exactly what it’s meant to do at its rated output.
