The Blue Sea system allows for both batteries to always charge with one battery isolated. No issues as with the Perko switch where if you leave it on both......a bad battery can drain the charge of the good one. There is a "combine" feature with the Blue Sea system which allows the isolated battery to "jump" the other if it loses charge. Do study the installation.
