Battery cabinets are frequently criticized for their lack of top clearance. For example, in a cabinet containing multiple strings of low ampere-hour batteries, there might be several shelves, each with one string of cells. The cell units on each shelf might be arranged two, three, or more cells deep. That makes access to the terminals all the ...
