I have a small outboard boat with 2 batteries one for starting and a house battery for electronbics. in the dc dc converter it says its not for charging. 90% of the time ill be charging my house battery in the garage. a small part of the time, im thinking the DC DC converter can recharge the house battery when the boat is running. I guess i would need to pick a single voltage for AGM house batteries.
any issues with doing this?
