My batteries stopped charing a few days ago. I noticed on the MTTP "Trends" page graph of Battery Temp that is had gone from about 80F to about 30F and the Low Temp Cut-Off kicked in. When I checked trends on my SmartBattery Sense, which is the source for the data according to the VE.Smart networking screen, they do not match. The MTTP temp is on the Status page does not match the current "Trends" page reading either. Please see pics. This kicked in a few days ago all of a sudden. What could be causing this?
