I'm setting up my boat for a 12v TM and want to use two batteries in parallel. I was thinking of running the two positives to a busbar and two negatives to another busbar, from them the power could be taken forward to the TM. Where I keep the boat there is no power, so I want to be able to unhook the batteries easily, so I think doing it like this, with anderson connectors, would be the best solution. Just want to check that there is no practical difference between linking the positives directly to the battery terminals as is usually illustrated. Hope that makes sense.
