What you really need to do is a load analysis to see
how much average current you are using over a larger
period of time. 10 amps might be the peak, but most
equipment spends the majority of the time at idle
current.
very simplified----- you could take 4.6 amps/hour for
about 100 hours. real world derate that due to battery
inefficiencies to about 80 hours.
