I twin F225 Yamaha outboards, with lead starter batteries and 200ah house SOK lithium. My set up is Victron multiplus II compact 2000, with 712 smart shunt, and 12-12-18 amp DC2DC charger. The DC charger is on an A/B switch for the port and starboard engines. I did this to balance engine hour use. I would like to add a second dc2dc converter, one for each engine and starter battery.
Engine Alternator produce 45 amps but uses 18 for the engine and puts out 27 to battery.
Can you advise what issues I should look for and is it possible to run 2 DC/DC chargers from each engine starter battery and what would the wiring look like?
