For each piece of equipment
you will be powering
with your unit, 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.
