BATTERY AMP HOUR RATINGS
 

Please bear in mind that the following table of amp hour ratings is to be considered accurate only if the controller is set at high, or 100%. Under normal operating conditions these ratings can be reduced by 40% to 60% as the typical controller setting is medium to low for the #2001 controller or 40% to 60% for our other controllers.

Please bear in mind that when using this chart to determine what size of power supply (as opposed to a battery) to choose, you will need to use the full amperage rating of the heaters in question. The heaters will draw their full amperage when turned on and unlike battery operation, the amperage cannot be averaged by the % of your programed controller settings.
