Connection options for 4-terminal batteries are illustrated in Figures 5-4 through 5-8. For low
rate applications (current levels less than 400 amperes), only two of the four terminals need to
be connected, but it is still best to use all four terminals for redundancy. For high rate
applications (current levels greater than 400 amperes), all four terminals should be connected.
