Need help with battery box

I am building my first ebike. A 20" fat bike with a 48v 1000w hub motor. I have a small income so I had to build instead of purchasing a kit.
I am having trouble with connections on the battery box I purchased from An power on AliExpress. It had no wiring diagram. I have no problem with the charge controller wiring or the batteries and BMS themselves, it is just the box, I needed a locking removable case because of theft problems.

What type of port is the single pin? RCA? How is the key switch and fuse connected?
Thank you for your help!

Judging from the pictures I'd say the charge port looks like a RCA connector. Connects to C- and B+.

If you look at this picture you can see that the Fuse isn't connected to anything by default. So you can either leave the fuse alone or wire it inline with the charge port with the appropriate amp Fuse.

The discharge port is a C13 IEC? That you can wire directly to your BMS via the P- and B+

But you want to use the electrical switch also then take a look at this pic.

the two key switch wires connect to B+ and the third pin on the discharge port.



Hope this helps.

Make sure you have a multimeter so you can check polarity of everything if you wire it yourself. Sounds like a good learning project.
