2800 cell 52 volt battery

Hi, I have just started building my powerwall and wanted some advise on wiring, I am doing a 14s (52volts) battery and since it will be taking a while before I get the 2800 cells that I need I was wondering if it would be a good thing to make 10 modules of 14s20p and link those in parralel?

What are your thoughts on that? Or am I better to stick with 14 modules of 200 parralel cells in series?

I think it is a good idea...
Smaller pack sizes allows one to get started sooner and it also makes adding extra capacity a lot easier. If you have 20 cells per pack then you 'only' need 280 cells to expand your 14s capacity. You may need a busbar arrangement that allows easy additions.

Welcome!

The challenge with this sort of approach is always the same:
As soon as you have the first 14s pack you can start. That's good. You can build your system modular, you can always add and take out one or more of these packs. In case of taking out, it can be done while the system is in full operation. That's good as well.
The bad part is that balancing has to be done per pack, it complicates wiring and makes everything more expensive.

You can do balance wiring so that all packs goes in balance but that is extra work to get thos edone. You need some type of contact to hook those 12 wires up in the middle

Thanks for the great comments, I was already thinking of putting some 14s 129amp Bmss on each pack, that way I am sure that everyting stays balanced. Also thinking of putting a link to my pc from the battery, that I can check all the bmss are working properly
