Well I’m just starting to look into the lithium option on a fairly new production boat. My first query is whether it’s possible to give a ball park $$ cost of changing out the house batteries for two 200ah lithiums that are EWOF capable. I’m assuming all the components will need changing including existing charger, solar regulators , fuses etc and alternator protection. I read somewhere only 3 brands will meetEWOF requirements…Juice, Victron and ?? . What kind of budget is realistic assuming current installation of AGMs is clean and tidy .
