POWER SUPPLY AMP HOUR RATINGS
 

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.
