Winter is Here!

I have now well over 5,000 miles on my EV and winter has arrived! My heater is installed, but I am waiting for an overflow tank before I can use the heat full time. Right now the pressure builds up and shuts down the pump because it's a closed system, but once my overflow tank arrives it will be an open system and I can run it continuously. It's about 900 watts of heat but once it gets going it does a nice job of keeping the interior warm and the windshield clean.

I have gone about 7 months without buying any gas, and I am going to spend part of this break testing the winter worthiness of my EV. I just watered the batteries last weekend, about 1/2 a gallon for the whole pack, so I don't use much water which is good. This pack now has 4,000 miles and seems to get stronger all the time. I am hoping for at least 10,000 miles from this pack, hopefully more. I have figured my break even point is about 6,000 miles due to the benefits of driving an EV, so I'm pretty happy.
