(You can zoom in and see the positive and negative indicators on the top of the battery)
Is this diagram correct? Keep in mind, this is half a 10s4p, ill just duplicate this for the other side of the battery
It’s really hard to tell with a half complete diagram. There’s a lot to guess at. 2 5s packs you want to make or just a really incomplete schematic? It’s a very good idea to finish your plan before you start work on the actual pieces.
I’m no expert but it looks like you are missing a balance wire and your pos/neg discharge wires. altogether. Hard to tell but are the P groups even right?
I recommend to do a bit more research and looking at batteries and finish the diagram of how you think it should be wired and how you want it made.
