The original idea was to have all in series. I had a Netgain Industrial controller. Up to 450VDC in, programmable voltage out (was set to 190V) and max out at 1200 amps. Liquid cooled ... and broken! I killed it by not connecting the liquid cooling before doing my testing.
Now I'm looking at using an older Cougar (P&S) so it tops out at 144V and 500 amps. If I use 3 strings of 128V, I won't stress the batteries much. 32 cells is divisible by 8, so that works out nicely.

You are in luck since i also need at least 3 more PCBs. I will order PCBs and when i get them i will resend them to you OK? Ill PM you for your address and price...

I'll check out the link and see what these boards look like ...

Its just PCB copper thin enough to only carry an amp or so. No need to be precise. When module shorts it draws plenty more than an amp!

Traces .. that works!
