Basically, I’ve got shifters, a rear mech and a seatpost battery. I want to run this 1x.
I will ideally use the bar end junction/charging point thing.
Need everything else, have absolutely no idea what I need or what wires up to what

Depends which shifters. I think DA have two ports in them whereas Ultegra and 785 or whatever they are only have a port in each shifter. If you only have an RD you probably don't need a Junction B if you can run a wire all the way to the front junction (Junc A). But if you're using the bar end junction, I don't know how many ports it has - is it enough for two shifters and a RD? Maybe it is with the Y splitter? But if it only has one port, you will only be able to plug in the shifters with the Y and then you're fucked with the RD.

Looks like it has two ports. So you use the Y cable for the two shifters and plug that into the bar end Junc. Then try and work out how to run the RD cable to that junction as well? Seems like a silly idea but would require the fewest parts.

Basically it splits the cable. I tried to use it to connect my battery and front mech to the 4-way junction without having two cables. In honesty I couldn't thread the bastard properly so I gave up and bought two more cables. If it's of interest, make me an offer.
