I think the perceived danger is that the string is capable of 2500 amps in a dead short, so people say to limit it to four at most because the current is less.
Meh a hydraulic or more likely a hammer punch crimp is designed for a proper connector and not a piece of water pipe, I don't think it will work.
I could I guess put proper termination lugs on it and bolt it down to one of the batteries on top of the bus. Kinda starting to have concerns about distribution though, but I should be safe because the max amps is equal to the max control of any one battery so safety wise it's ok
