If you plan to run something for an extended period like over an hour you will need more battery, much more. Those batteries are just over 100 amp hours.smkettner wrote:
Minimum 100 amp hours for every 500w is the rule of thumb that I know.
I am wondering more about the current carrying capacity of the battery itself, not the available amp hours. Can the internals of deep discharge batteries handle high enough current to support the load?
