We have a 1 year old Sprinter cargo van that we use as a campervan. About 4-5 months ago I installed a charger that keeps the vans starter battery charged using energy from our 'house' battery/solar in the back of the campervan.
This charger comes on whenever the engine is off. It is a victron DC-DC charger, and I programmed it to supply 12.7v to the starter battery.
My goal with this charger was to keep the starter battery from getting into the 12.5/12.6v range where it starts to show warnings in the dashboard about a low battery. We sometimes use the vans built-in wifi router when the engine is off, which has a large draw, so without this charger we could run the battery down too much.
Recently I started to get an error in the dashboard of the van while driving warning that the battery was too low (suggesting I pull over and leave the engine running to charge it up).
It is an awfully new battery to be having issues, so I am thinking something about how I've been charging/maintaining this battery while the engine is off is killing it. I don't know enough about AGM chemistry/best practices to know what though.
I'd appreciate any help/insight from the community!
