You could use 6*0,15mm nickel for 5A. If you use copper then 0,5mm diameter / 0,2mm² should be enough just so for 5A. That is 24AWG/25SWG. However this is close to the limit on both nickel and copper, to be on the safe side you can always get up one size. So 7*0,15mm nickel or ~0,6mm/0,3mm² copper, 22AWG/23SWG, would be appropriate to have some spare capacity on the connections.

Do you recommend a source for this?

I don't buy nickel strip very often. Last time I bought some I bought it from my "local" 18650 wholesaler which is eu.nkon.nl. My last copper purchase for 25SWG was via eBay from a company in the UK called Scientific Wire Company because they had the cheapest offer. I never bought from any chinese merchants on eBay so I can't recommend any of them, just because I haven't had any business with them. The big ones like GearBest.com and banggood.com however are trustworthy. If they have something like this for sale then I wouldn't have any problems buying from them.
