Is your E10 being used in winter (snowblowing, ploughing)? If so, see to it that you can park your E10 in a location that is not below freezing. Or you can heat your batteries. Charging your (Leaf) Lithium batteries when they are cold (below freezing) will cause them to fail quickly from something resembling internal metallization as the chemical processes slow down enough that the charging current cannot be absorbed quickly enough by the cells. Just to avoid disappointment... (remember the big brouhaha about Teslas not wanting to charge in the cold, recently? That was because the tesla battery heater is not actually a heater, but they re-program the motor controller to circulate large current, causing losses which warms up the coolant, which is used to warm up the battery - slowly. Thus, everyone who drove their Tesla late at night, parked it empty at their home and tried to charge in the morning, had to wait about 3 hours *while* plugged into the Supercharger, in order to warm their battery enough that it could *start* charging. Hence the excessive wait times. If your DIY battery pack and charger does not regard low temps, then you are the only one preventing your battery from destruction by charging in the cold... Hope this helps, Cor.
