The higher the quality of the batteries (read; lower internal ressistance) the colder they stay.
The controller on 80 degrees, why don't you use a fan?
It depends on how the controller is developed/designed.
Let's say a transistor/fet can deliver 25A on 20 degrees, when the temperature rises till 70 degrees, that same fet/transistor can only deliver a 5A So it depends on the amount of fets/transistors that the controller has got in it, how much A it can handle when it is 80 degree, but it is always less than when the contoller is cool.. A fan might be handy for you right now.
