Thanks Cor,
Yes, it has a standard 14V alternator regulated. I start and stop frequently as skiers are getting in/out of the boat, so curious if LiFePO4 dies suddenly or gradually like lead. I assume a small battery like this would start fine one second and then not, so I keep a spare battery in the boat (unless someone has any real data on this battery, couldn’t find on the great god google) . What is the projective life, 1,5,10 years? I had an electric boat www.evalbnum.com/2749 but couldn’t H20 ski behind it so bought a lean burn Honda BFP60, same engine that was in my 2000 (real) Insight 65mpg. In the alum 1200lb 6x16 boat, gets 6.5MPG which is considered “good” most fiberglass 3400lbs are 2.3MPG. Have a renewable energy day, Mark Mark E.

That said, your 4lbs battery probably has between 200 to 300 Wh of capacity at best, using normal density numbers. At 12.8v this means probably 15 to 20 Ah so the usual Chinese twice (or more) overspec. Cor.

Looks more like 7-14ah MC battery. It does start the engine with little voltage sag, 11V whereas the lead battery sags to 8V when starting. I'm concerned that it may suddenly die out in the middle of the 80 mile lake here Smith Mountain Lake near Roanoke, VA so keep a spare tractor battery on the boat just incase. I replaced a 40lb lead marine battery to save some weight but curious about the longevity and how LiFePO4 dies, if it's sudden or gives some warning like lead (that gets gradually saggy when starting).
