Kirpal, Keep in mind variations in upper- and lower-bank temperatures from ambient heat stratification if the batteries are in an indoor space. This affects relative SOC among strings, affecting string life.

Typically we don't like to stack flooded batteries but we may not have space for as big of a bank as we need if we don't stack......Any one know of a company that engineers racks that are seismically sound, have the ability to have spill containment all while maintaining some accessibility? I know DPW makes battery racks but looking at their web site they are typically smaller than what we need..... We need to support roughly 7000lbs.....and are exploring if this is even doable....
