It's not clear what you mean by "constant amps" in that context, but the battery tester that the OP linked to is designed to apply 125 amps for only 5 seconds. This will not harm an FRC battery; however, it won't give you as much useful information as other testing methods. See posts 9, 12, & 28 in the thread linked below

2. It doesn't do internal resistance which is very useful for finding dead cells

The jury is still out on whether weak cells can hide from a short-duration, low amp, internal resistance test. See posts 25, 26, 29, & 34 in the thread linked below

See post 27 in the thread linked below. For a home-brew solution, see posts 12 an 33 (competent adult supervision required).

Where the Battery Beak shines is for quick-testing batteries at events prior to putting them in the robot.
