I have just fitted a second leisure battery but just to be different thought I would do it my way. Replaced the good van battery and used the old one as second leisure battery wired thus......both neutrals together and lives wired to a marine battery switch which gives the option of using batt 1 batt 2 or both. Also wire individual mini cheapo voltmeters to each battery for individual monitoring.
My thinking is if van battery fails I have a spare and when and if leisure battery gets low if off ehu I have the back up 2nd battery:thumb: also if I get a battery go down it wont drag the other down and can simply carry on using other battery.......... cannot see a downside...............can you?
