Are multiple shallow cycles harmful for batteries?

Hi BFL13,

Thinner plates lend themselves to smaller voltage drop. There are twice the number of cells in twin 12 volt jars as in twin six volt jars. Therefore output per cell in the 12 volt jars is 50% of what it has to be in the six volt jars.

Obviously on a 200 amp load, with twin sixes, each cell has to do 200 amps--twin 12's, only 100 amps per cell. Which do you think would have greater voltage drop?
