I have 2 100AH lithium batteries on a boat where the negative is parallel jumpered at the batteries with a single negative wire going to the load. The 2 positive terminals run independently to a battery switch about 6 feet away. 99+% of the time, the battery switch is set to use both batteries and the load draws from both. This has never been a issue. Can I just treat this parallel bank as a single battery? From reading other posts, it seems like the long leads to the battery switch may not be a good idea. This was the factory set up and I can’t see a great benefit in trying to manually manage these 2 batteries independently.
