Rearrange your pack to double the depth ( rows 10 deep)so you have 10 series connects rather than the 5 you have now.
8x.2mm Ni can take about 8-10 amps continuously and 15 for short periods. More than that heats it up quick smart. At 20A it gets hot, 30A very very hot , 50 dull red glow, >60a it's bright red hot.
I suspect you'll need to solder copper strip/wire over the top, also learn up on current sharing, and look at how to attach your power leads.
Being split is also going to raise the complexity. Do some more homework before you start.
I can't rearrange my packs because only this shape is going to fit my bicycle. I can connect those two pack with hard copper wire like it would be only 1 pack. Packs are going to be in their 6mm thick plastic boxes and separated for only a few centimetres. I don't have a spot welder so I will probably just go with thick quality cooper wire. I just don't understand how I should do connections between the cells. For power leads I plan on using 2 awg cable with some sort of connection that will hold up to 200A peak
