First post here so don't judge me
I'm building a battery pack made of approx. 700 18650 cells split into 4 smaller cell packs.
Each cell pack will be supplying 250A peak and they're all in series to get a total voltage around 400V.
I want to use nickel strips spot welded to the batteries to connect them but the currents get too high, especially at the outputs of each pack...
What is the best way to connect 18650's for high current applications?
Thanks in advance!
