Hello to all. I am a new owner of an Imagine 2600RB trailer, and have installed solar panels with a separate charge controller to a new LifeP04 battery that is located inside the trailer where you put your dirty shoes. Where on the 12 fuse panel can I connect the positive and negative from the battery. I have a 12v switch in the positive so I can disconnect the LifeP04 battery and use the standard battery that is located on the tongue. Thanks for any insight/help in advance.
