I planned on putting a fuse right after the 72V terminal just in case of a short or something. I was thinking the blade switches might be good since they for the most part would never be used and I was wanting something that would be really reliable and could be operated by hand if the need arises. Maybe just putting a fuse after every other battery would work and not bothering with making it overcomplicated.
Contactors might be the best option. Where can I get a good one at? I didn't see much point in using one and also a fuse since I doubt it is possible for the three phase controller to stick wide open and even if it did the brakes can handle it considering the gearing.
