Hi everyone,
Longtime lurker - finally doing a system upgrade. Hoping for a math/brain check.
I have a 32s winston260ah pack that I am replacing. 102v nominal.
I’m looking at purchasing 66pcs 280ah EVE cells and running them in 33s2p configuration, with a BMS capable of handling paralleled cells. Let me know if you’d recommend something besides an OrionBMS2
My load (traction motor mainly) pulls 170amps average, but can spike up to 400amps for 10-20 seconds. These EVE cells don’t have great discharge alone, but in the 33s2p config I’d have ~106v nominal at 560Ah capacity:

This system is charged with an ElconPFC5000. Not entirely a solar setup, but these forums are the best EVE/CATL Lifepo4 updates. Will likely be Docan or Qishou cells.
Thanks for looking, let me know if cell connections/clamping, cell discharge, fuse placement, suppliers, bms look alright. Cheers
