I recently had lithium batteries installed on our boat. If not done properly, it can create serious problems with a boat. I'd done a ton of research before deciding to do it, but the biggest issue was to do it safely and to make sure everything was working nicely with the lithiums. That meant the two Balmar 612 charge regulators that regulate the power coming from the two alternators, the Mastervolt Chargemaster 12/100-3 charger, and the Victron SmartSolar 100/50 all needed to be properly configured so the batteries don't get over or under charged. I'd been told that the best in the business was in Annapolis at Marine Electric Systems by other sailors, one of which had had an 1,800 Ah lithium system installed on his boat by them. I was not disappointed! Patrick and Rob know boat electrical systems better than anyone I've worked with in the past. I ended up hiring Rob to come all the way down to Portsmouth, VA to do the install on our boat. He was fast, efficient, and the quality of his work was flawless. Just as importantly, he answered all the questions I fired at him and made sure I understood him. If I ever need electrical work done on our boat again, they're my number one choice! read more
