I have a 2006 Phaeton that needed the house batteries replaced. I thought it would be a good time to upgrade to lithium batteries. For $1,200 I purchased Epoch 12v 480 hr lithium battery. When I switched out the four 6v batteries, everything went crazy. Turns out the Tiffin inverter would not work with lithium batteries. So I’m committed now and purchased a Victron MultiPlus II 12/3000/120-50 inverter charger for $900. Works great, except my control panel besothe Tv no longer displays batery status, blacb, grey, and frest water levels. I tried plugging in the data cable 6 wire phone jack into the victron, but no results. I know I can buy a battery monitor from Victron, but how can get the black, grey, fresh monitos to work? Advice please.
