Add a battery and lithium iron phosphate house battery

[Sangster21]

I am doing some rewiring on my Sangster with mercruiser sterndrive. I bought the blue seas 7650 add a battery kit and have since decided to go with a 100ah lithium iron phosphate house battery. Can anyone wade in and offer advice on how to properly wire it all up? I have a Mercury kicker and an alternator on the main engine. I am pretty sure I need a dc to dc charger as well. Thanks, Alan

From my post last week: https://sportfishingbc.com/threads/...e-marine-boat-applications.95794/post-1198173



The +ve wires at the bottom left are coming from the two start batteries. The +ve wire leaving top left goes to the LiFePO4 house battery.
