Battery Groups Glued and 50 Amp Connector

The 50 Amp Anderson connector came a few days ago and I have purchased a 30 Amp fuse holder and 30A fuse. I think I have all of the stuff to finish securing the battery holders to each other.  I did not like the exposed wiring connections. It looked to me that when I was connecting the batteries into the holders it was possible that the exposed wire terminal ends could get in contact with another battery holder terminal.
I used High Temperature hot glue to glue the battery holders together.

I connected the keyed battery cutoff switch inline with the negative battery wire.
