I might have missed the whole point of the question but I assumed lolailando was considering cells groups of smaller cells arrays from a "bulk" buy of unmatched cells. I'm sure he can clarify.I very highly recommend that you look at larger capacity cells, and use fewer than 200. You are introducing a lot more points of failure, bus bars, wires, fuses, multiple BMS, etc. You can buy 1000Ah cells, so I would start with that. 16s or even 16s2p of 1000Ah is going to be a whole lot better than 5x as many 200Ah cells.
