I would be interested in those boards however i am going to give it ago myself first. Ive got an 18s2p pack which potentially i might go to 21s2p or even 24s2p. but I am dealing with a hua tong 72v controller so I will start off with 18s.
Go lots of 3s jst connectors which can be soldered direct to veroboard (stripboard) so great for paralleling packs. (my packs are all 3s.
going to build up in 9s blocks cause then the pack can be halved paralleled and charged at 9s4p on my hyperion. Anyway just thought id share and say congrats thats a tidy setup you have made. will post some pics of mine when i get it finished.

How configurable are these board?

With a bit more experience, you'll learn to chuck any pack that needs balancing much, and stop fretting about being .01 out of balance. Then you will only need to break out the ribbon cable once a month at most.
Just so noobs understand this clearly, your setup is not paralelling the entire pack to 6s, while the main wires are connected 12s. It's just paralelling each pair of 6s packs, then getting charged with a charger that can charge both 6s packs at once.
It's a subtle difference to understand at first, but you grok it much quicker when you make the mistake and see the huge spark.
