Looks good. I am very interested! I have a set of these batteries sitting on my bench that arrived on Friday. I measured things and one issue is that the pigtails do not include a connection to the battery positive terminal. You need to add a wire for that. (there are only 7 wires and 8 are required) When you connect the two modules, you get one of those but you will still be missing one for the total positive terminal.
Have you decided how you will mount the modules to the cart? I am still thinking about this problem. I will put them together like you show them - my Yamaha cart has a clean battery bay with nothing in the way of the much smaller battery vs the FLA ones. I won't be doing an onboard charger - I will have two carts sharing a charger for now.
Also - be very careful with the pigtails. If you short one you will likely lose the connection to that cell and I don't know how they are internally attached. I am thinking of adding 1 amp fuses to mine. Those 22 gauge wires will act as fuses if there is no other protection for them. I wasn't worried about this for the older Leaf modules because you could easily replace a sense wire but on these, I have no idea if that is even possible.
