the last two weeks I finished my powerwall project. On the ToDO list:
28 batterie packs 60p
At the end it's more effort then the bigger 120p packs because of twice of the amount of busbars
I solder the fuse wire in one piece and at the end I cut the unnecessary pieces
almost ready
just need to solder the fuse-wires to the busbars
next step: balancing all the packs
pretty dangerous so close together, I do recommend not to do so
for me it works well but I_ve done this just several times
on the other side there are sitting the 120p packs, but they need some time to balance too
after 48h of balancing the 60p are balanced and ready for installation
they will support the 11KWh system at the pigsty
all wires are 16mm² as well as the busbars
I decided to take the BMS plate out again and make a modification
I want to add a external voltmeter to the locker so I can see the battery status while walking past the locker without connecting to the bluetooth app, so I have to add a shunt
then back again with the bms and with all battery packs. Two systems with 14s60p each fits into one compartment
next is to customize the bms wiring harness
