Happy Breffast!
Well I can find Nothing in the current 2020 NEC about fusing individual batteries. Regardless of being posted on Here or not. If its not in this edition of the Code then its not required nor needed. IF it was a common danger then the Code would have it listed.
Please cite the portion of the NEC that requires a BMS to be used on batteries made from Lithium cells.
Are you fully versed in article 706 and the requirements for ESS?
Yes my experience goes back to my USAF air craft days, never did I see a fuse between any batteries! Even those early NiCad ones.
An old NiCd isn't comparable to the ultra low resistance of lithium cells, particularly the larger capacities (280A) where the total 4S cell resistance is typically less than 0.8mΩ.
