yes.
you can work out the amp hour draw.
your battery: 90ah 120ah etc.
your pump: Shurflo 100psi 7ah(max flow) x2 pumps (14ah)
times how long you work: 7hrs a day
total: 49ah (1 pump) 98ah (2pumps)
thats is for MAX flow of your pump, we dont ever need to use 5ltrs/min with 1 pole. usually 1.5-2ltrs min. The ah draw will be roughly 50% less.
a 120ah battery should then give you 2days work.
