Do the balance connections only support up to 8S geometry?
It’s 7S only, in one line you can connect up to 7 pcbs then you can do another line and connect them in series that way you will have 14S
How about 12s? Would have to buy 20? PCB’s
1 PCB per 1S3-4P, so 12 PCBs
Sorry, I forgot about those. I added 12 and 14 pcs.
Here are some exampels how to use them.

The nickel strip was just example, you would need use way bigger strip or different material for high current application.

How you connect two serial groups? Another strip between pcbs?
U can use, strip (but I guess can break from much bending), Use wire, Use flat copper mesh wire its up to you imagination. Balance leads can be either single wires, ribbon cable or I don’t know 
How many amps can these carry
It does not have current going through the board apart balance leads which can handle 1A no problem (nobody balances higher amperage)
How much amp it carries depends on what you use for connecting them together. If you solder 0AWG wires it will handle that those 0AWG currents 
Its just place to connect two wires from terminal basically.

Everything depends on how you connect your cells together

I’m putting together either a 6 or 8p 10S flat pack with these and all the extra mf1 cells I got laying around, P will be determined by width of deck. Each P will be dual layer. I’m considering sandwiching the PCB, make the PCB series chain first, then add cells
To all the folks with the eBay 10s2p packs this PCB is a great way to rebuild the packs and leave all the spot welding intact
