Hi! I started making a 10s3p 30Q (so max 60A discharge current) flat battery pack. I used 10 x 0.15mm nickel strips and doubled them on the series connections. Now by looking in the forum the main suggestion would be to add a copper braid wire on top of them. Do you know any convenient source for them in EU? I need it now otherwise I would go for Aliexpress. I also have copper sheet and copper bare to use instead of braid wire. Do you think it is a problem to solder the copper on the nickel stips instead of weld it. I would put a spot of solder iron on both nickel and copper and them solder them together (I hope fast enought to not heat up the cells). Do you any other way?
Thanks a lot
