I never did find the datasheet for those motors, even when current. Closest I found was M57STH51-3006D which made me wonder if 3008 was a typo. On mine the number is printed by dot matrix, not very readable but it looks like an 8.
Anyway, I have been running them with Pololus for some time so they should be no trouble with DRV8825 I think.
