Thanks. I'll try finding a distributor in the US to chat with about these. I know there was a recent post about these batteries.ChrisSent from myPhone

Chris, I am finishing up building an electric boat. It is not as big as yours, but due to its mission I will have a system similar to yours. In my research of all the battery options, I have settled on the NorthStar AGMs also. I feel they are at the moment, the most cost effective and heartiest. I am using the SMS-AGM 480 series battery. Being made of pure lead, and the AGM tech, I think they will serve the best. These taller, thinner cells, neet my need and I do not waste a lot of room in cell shells (battery cases). They work in all 3 axis, and I get them from a supplier just 20 miles from the factory in Springfield, MO. If you will look for a local supplier, and talk to them, you can usually get a healthy discount from the MSRP. Yes you can get other options. But when weighing the cost, shipping, and real-world life in your application, I think NorthStar is a great choice.Dan----- Original Message -----

Subject: [Electric Boats] Battery replacementHello group,
I'm shopping for new batteries for my sailboat. I currently have 16 Trojan T-145s in series parallel. 520aH total at 48 V. They have served me well and will soon be 6 years in service. I'm wanting something in this capacity, but in a more maintenance free design. I have been reading the various battery postings from this group with interest. I have not totally ruled out LifePO4, but I have concerns with BMS failure, charger integration and, of course the initial cost of a system in the capacity that I require. I forgot to mention, my boat is a Morgan Out Island 41. With my experience with this boat and the smaller size of my generator, I don't want to reduce capacity much. The other battery that I am considering is the NorthStar NSB 210FT BLUE+. They are essentially an AGM battery with carbon added to allow it to better tolerate partial states of charge (PSOC). One thing that I've noticed with my T-145s is the incredibly long absorption time while at anchor. Most time I just give up trying to get to 100% SOC, which I understand is not good for FLA batteries. 8 of these NorthStar 12 volt batteries (400 aH total) would cost less than half of a comparable capacity LifePO4 (CALB) bank with BMS. I'd like to get some feedback/opinion as to the suitability of these NorthStar batteries for this application, and maybe someone can give me more confidence to make the LifePO4 plunge.. Thanks for any help this group can offer.
Kind Regards,
Chris Hudson
