Upgrading House Batteries to Lithium

[moabdds]

I installed 3 Battle Born batteries for my coach along with the battery isolation monitor sold by Battle Born. This takes care of the charging problem with the alternator, so you don't have to install an inline switch to turn off charging to the coach batteries while driving. This switch has the potential for problems if you should forget, which is very easy to do. I will admit that installing the BIM was a pain because of access, but I managed to get it done and it seems to work like a charm. Battle Born recommends about 250 watts of solar per battery, and I have 1000 watts (4 x250 watts), so I am over-paneled by 250 watts so the system charges faster with less sun. I installed the Victron 3000 watt inverter, which has a 120 amp charger for the coach batteries and a separate trickle charger line for the starter battery. If you'd like to see my set-up, contact me privately and I can send photos.
