With lithium do we actually need a dedicated starter battery?

Here are the better curves...right i was at 14.4V. Still need 6 cells. 14.2V gives you above 80 till 85% SOC but curve is not linear so about 33-35AH then, still enough so to easily start and operate windlass and you can use 100% of SOC compared to Lifepo4.
And you have your DC2DC getting it then to 15V and due to higher voltage both need less AH to start or operate windlass. Especially windlass you will hear and see how fast that suddenly runs.
