We have added a split charge system to the land rover so we can power the laptop and compressor from a second battery when using the Clark Mast.
The rear seats on the passenger side have been removed and a box built with a padded top to hold the battery, jack and recovery kit. On the end of the box, we fitted two isolator switches and a voltage-sensitive relay module which splits the charging current between the main and second batteries. Both batteries are protected via a 60A fuse.
