Where does it go?

[SailingTy1970]

if you follow the Complete LiFePO4 Solar Battery System Design video; after you connect the 48v to 12v converter to the 12v relay, where and how do you add the 12v fuse box for connecting 12v systems? Still learning so please, no sarcasm, just constructive instruction/education please

This one?

Note that the first line in the description is "this video is outdated"

Don't use that video. It's not correct. The BP is being used to cut off the inverter, and this is not an allowed use of the battery protect.

What are you trying to accomplish?

 

[SailingTy1970]

I want to build a 48v LiFePO4 Battery bank Solar System for a sailboat. I want to have an inverter for the AC items and a 12v system for the DC stuff. I like and understand most of the things in his video but once he puts the 12v relay on the converter I don't see how to install a 12v panel for individual items or how to attache it to the fuse panel/switch.

Here buddy, 48v to 12v to 5v if you want to power any 5v devices like usb phone chargers or in this case a WiFi modem

Or even better this one! It’s an RV application so closer to yours.

DC Power Part 1: 48V to 12V Converters, Relays, and Fuses

After getting the A/C power mostly squared away and tested, it was time to tackle the 12V DC "house" power side of things. Most modern motorhomes actually have three discrete electrical systems powered by two separate sets of batteries. The first electrical system is to power the vehicle part
