Currently on a road trip from North Carolina to California and my batteries have died (current voltage is 4.5v).
Wole up this morning, turned on the coffee maker and went into the store. When I came back had hot coffee but noticed the coffee maker light was off and then discovered all power dead.
Checked voltage at batteries, about 4.5v. Batteries are charged with a Victron DC to DC charger, I noticed green light is not on when van engine is running, and app shows only 0.8 output so can’t charge batteries with DC to DC charger.
Attempted to charge using Victron blue smart charger but when plugged in to 120v outlet no lights turn on when charger is connected to Battery. Disconnected from batteries charger starts up as expected. So I can not charge with shore power.
I’ve checked all fuses, none were blown. This system has operated without issues since installed about a year ago, most recent trip was a few months ago, 24 days North Carolina to Nova Scotia and back.
No idea why the batteries died or why I cannot charge by DC to DC or shore power, is it possible the batteries at such low voltage are now shutdown by the Batteries BMS,s?
Anyway I am now without power. I built this system with the help of some very knowledgeable people on this forum, so here I am now asking for help again.
