Does cold weather affect the cars performance?
In general, batteries don’t hold their charge very well at low temperatures. We would recommend wrapping the racks in insulation if the car will be in below 40 degree weather for extended periods. A battery warmer is a good idea as well. There are a few battery warmers on the market and here is a link on how to make your own: http://www.instructables.com/id/EV-Battery-Warmer-Part-1/ Battery warmers could be installed below the Nose and Trunk Rack. The Top Rack doesnt have the clearance below, so the warmer would need to be installed in the rack below the batteries. The battery hold down straps would then need to be modified since the batteries would now be higher than originally designed.
