Now that we are in -10 weather up here in the New England, when I go out to start my E it does not give me too much confidence... it starts with a very SLOWWWWW UR UR UR then finally catches but almost sticks a little bit on the final UR prior to starting, and then makes an extra noise for the first 15 seconds of cold running, this goes away but have no idea what it is/was... and yes the battery is about the size of my lawn tractor, maybe there will be an aftermarket battery tray and we can all put real batteries in our E's!
