One cabinet should be able to hold at least one complete string of cells. Best practice is that strings should not be split between two cabinets in order to ensure reliability of the entire string. Figure 1 - Battery cabinet with top terminal cells A battery disconnect switch should be located as closely as possible to the end of a string.
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.
Cable lengths from multiple cabinets should be kept as nearly identical as possible to prevent voltage drop variations. One cabinet should be able to hold at least one complete string of cells. Best practice is that strings should not be split between two cabinets in order to ensure reliability of the entire string.
Sometimes a viable solution is to connect multiple batteries in series, parallel, or a combination of the two. It is good practice to only connect batteries of identical capacity, type, and age. Series If you are hooking batteries up in series, connect the positive terminal of one to the negative of the next, and so on.
Battery cabinets must enclose the batteries behind locked doors accessible only to authorized personnel. As long as the cabinets are kept locked, they can be located in a computer room or other rooms accessible by non-battery technicians.
Generally speaking, the larger the battery (both physically and ampere-hour rated), the more likely a rack configuration will be considered. There are no hard and fast rules, but typically once a battery unit (single-cell or multi-cell) gets above 100 AH, it favors rack-mount. Below that, cabinet mounting should be considered. Number
