Heine's Ramblings and Rumblings

Batteries and charging

I had 5 Optima Yellow Tops from the Disco and the trailer . I decided to use 4 as auxiliary batteries and also replaced the starting battery with one . I used a National Luna battery management system and a Link 10 for monitoring . As I had already removed the camper to have the load bay rubberised , it was quite easy to get to everything .

Two batteries each side of the camper. They are accessible through the hatches in the bed . I wanted to put them as far forward as possible and also balance the load , as the 4 come in at over 120 kg .

Right pair . The shunt for the Link 10 and the fuse box for both the Link 10 and the additional pumps for the fuel tanks (that are still to be added) can be seen on the right hand side

Below are some of the Link 10 display values
