I plant to use the lifepo house battery (2 x 12 V 280 Ah in parallel,( https://diysolarforum.com/threads/waterproof-case-for-4-280ah-eve-or-lishen-cells.17740/ ) ) in combination with a 10 hp Yamaha high thrust outboard, for charging the battery and for starting the outboard. Is there any experience how the outboard engines work with a lifepo battery?
The charging circuit is using simple coils, a rectifier and a regulator (see attached picture), the coils can generate max. 10A. I may reduce the max voltage by using two high power diodes in rectifier configuration to cause a voltage drop of 1 V to the battery in order to be at a safe voltage below 14 V for charging.
