I left two batteries out in the freezing cold garage last winter. Both were partially charged. One was a 48V 10A H Life4Po in a case (yours) and another was a shrink- wrapped 48V 20AH Lithium Manganese from another company. After being charged, both only ran for 7 miles. When they ran out and I put them on the charger, they still read 51V out of a total of 54.6V!!!
What the heck? Did I ruin them by leaving in the cold or is there some connection not being made? Could they be salvageable? How can they still have voltage in them but not work? Thanks in Advance.
