The Genesis NP18-12R battery (2012 FRC KoP) datasheet¹ indicates that it is rated up to 150 amps, so in theory you could measure it with a 100amp load tester, but:

1. The datasheet does not list any manufacturer specs at that high discharge rate, so any assessment based on testing done at that rate could only be relative to other batteries tested the same way.
   
   
2. In the wrong hands, testing at 100amps could damage the battery or be a real safety hazard.

Use something else.
