I plan to convert my battery setup from the original FLA batteries on my 35ft sailboat ( 1 engine 70AH and 2 service 70AH ) with lifepo4 batteries (200AH setup)
I don't need a lot of energy, nor AC power inside the boat, but I need security and reliability.
Needs are basically (maximum values) :
- Laptop : 3A
- Electronics : 2A
- Fridge : 3A
- Navigation lights : 1A (led)
- Cabin lights : 2A (led)
- Autopilot (? average 3A ?)
- rarely : anchor winch ( ~100A ? ) -> He will stay on the engine FLA battery.
I'm rarely more than 3 days at sea.
The original setup is the following. (I dont know why there is a GND swtich on the original setup, any Idea ? installed factory by Beneteau).
I plan to convert to something like this.
Any advises/recommandations about this setup ? (missing breakers ? fuses ? ...)
