Lets say just 20hp from each engine is required, that's running about 30kW.
At the 300 hours, that's 9MWhours.
A single gr31 deep cycle is good for about 1kWhour, so, that the equiv of 9 thousand grp31 are required.
Are you factoring in 925 gallons of diesel and an integrated generator?

Some manufacturers give ranges at different speeds...a similar thing would be helpful with this technology, such as what ratio of diesel generator run time vs solely running on stored electric power at different speeds with the approximate distances.
