I still wonder why the idea of using capacitors for the cranking function has not caught on specially for large diesel motors. Use a bank of caps with a battery serving as the deep reserve tank.

Six 12V batteries at 280AH each would be 1680AH.
If you have six 6V batteries they would be 560AH each.
Either way those are some large batteries.
OOPS! Bad math on my part.
Six 6V batteries at 280AH each would be a total of 840AH, not 1680AH. Each pair of 6V batteries, wired in series, makes a single 12V battery of 280AH.
Batteries in series add the voltage, but the AH does not add.
