great pictures! exactly what I wanted to look at today. how many cells total were there 48? =)

48 total (4 in parallel and 12 in series), which gives me 50.4 volts 12x4.2v.
got question about bms wiring. if i use a wire for series (awg) where will can put the phase wire? (positive side or in the negeative) or does it matter where?.

If I understand you correctly the 12 BMS wires just need to be connected anywhere you made the series connections. There really isn’t a positive or neg side to that.
does it matter where
it does not, bms is just looking at voltage at that position.
thanks for the reply bro’s, good to know that! i didn’t use bms on my previous build.
wish i knew a good place to get those thick nickle strips

Nice work… do you make batt packs?
I suggest u copy what you just wrote and create a new thread and past it over for that this is a old thread that has nothing to do with what your asking
Hello, very Nice battery build. I bought 50 cells today and plan on the same config as you. Can u please tell me what BMS u used and what kinda spot welder that will do for a few batteri builds. also the layout config of plus and minus ?
