For each piece of equipment
you will be powering with
your CPI 150, you must
determine the battery's
capacity (how long the
battery can deliver a specific
amount of current). For
example, automotive
batteries usually provide
25 amperes of current. A
battery with a reserve
capacity of 180 minutes
can deliver 25 amperes for
180 minutes before it is
completely discharged.
