14s20p PowerWall
#1
Hi guys, the building begins !

I used rePackr to make my 14 sets of 20 batteries :


Then, I made the barbus :


Ready to sold :


Soldering the fuses :


I have a question about the fuses : Is it needed to sold one fuse at each end of each cell ??

Ho ok, each side seemed a little extreme lol

What about the other side, what should I use to link the cell to the bus bar ?

Some copper wire, like 0.75mm2 or so, just to keep the cells from turnig in the holders.
Lots of examples everywhere here.
