On the Patron I put a generator on the stbd side. Not only did it balance things out it solved the power problem. Two things that will get you thru the night (on the boat that is), Led anchor light and I plumbed the bait tank so that my secondary bait pump was a low amp pump. No good when running but ok on the anchor. If the primary pump took a dump during the day I changed valves and switches and it gave me time to change out the bad pump.
New boat has 4 class 31 AGM so I can party all night long. Do recommend looking at the AGM’s.
