how do you figure out how many amps?

I've always wondered about this eagle tree elogger things.. surely theyre only really useful for HV setups, being limited to 100A, or the newer ones 150A. Even then it seems like your really pushing its limits, will that thing blow if you over current it? I nearly bought one not long ago but was concerned that I'd be throwing $150 down the can on my first full throttle start...
