Title: LiFePO4(LFP) battery upgrade
Post by: azuro on April 04 2026, 08:06
Hi, all. I am going to upgrade to 2x314Ah lifepo4 battery pack w. OrionXs50A dc charger for my B42Cr, 2006 sailboat. Since I am not an electrician but diy sailor, I am looking for a typical diagram. Very basic usage for now, only the fridges, windlass, coutesy lighting, etc.  Just went thru the forum but not a complete answer.

I appreciate advice, experience but a full diagram from the community. Thanks.

O.

Welcome

That is a huge amount of capacity for such modest usage - something like 5 times as much usable capacity as the original. How are you going to charge it? Do you have plans to live aboard for long periods away from shorepower with increased daily usage and a lot of solar to keep pace with consumption? Windlasses and bow thrusters are normally powered by the start battery in lithium installations with an interlock so they only get power when the engine is running.
