Roger,
This is a series string of 13 Optimas. The only thing paralleling the entire string is the 156v Zivan charger. There is a master disconnect switch in the middle of this string and of course this switch needs to be closed for the Zivan charger to work; however, it doesn't matter when charging with the small individual float chargers whether that switch is open or closed. The small float chargers are all isolated and each charger is dedicated to only its battery. There is no path for this float charger to provide any current outside the battery it is connected to.
Sorry for the long wordy answer :-)

And you plug them all in at the same time. My question is....Are the batteries still connected in series when you activate this net of float chargers? If so, wouldn't the chargers - and batteries - interact with their neighbors in the series/parallel strings? Or do they?
