When I had my 110 volt, 48 volt system in the Yugo, I could run to town in the mornings even though the temperature was 35 degrees F.
Now that it is a 72 volt system, I hardly can get to town when it is below 40 F.
Thinking this over has brought me to the conclusion that the battery pack was warm from charging before, because I had the charger on a timer.
It would charge for 3 hrs and then be ready to go 10 miles if I had to, with the warm pack.
My 220 volt, 72 volt charger is not on a timer and it charges from 11: pm until morning with a tapering off charge. By 7:AM, the pack will have cooled down and lost power.
I don't want to go out at 4:AM to plug it in, so the next best thing is a timer for the 220 charger.
Should be able to locate one at a sale.
