As far as temp. settings, 155 degrees F is what I normally use. I have that set for quick warm. For "step" warming, 120 degrees F for 20 minutes (to bake in traction compound), 5 minutes off (apply more compund), then 10 mintes at 155 F.
To get the best results, especially when using RP or CS tires, the S cans are made to fit the smaller tires.
I have not heard of any issues with charging the pack inside the unit. Double check all your connections, and if you are still having the problem, contact James @ Much More, and he may be able to shed so light onto the problem.
