It isn't "soldering cable", it's not even "cable". It's just standard "wire" that's been soldered to the batteries.

Those look like 'AA' batteries, so that's 1.5v x 3 = 4.5v total.

A length of insulated wire stripped out from some domestic electrical flex can safely handle that

That's assuming it's just for the batteries, there must not be any high voltage/mains voltage involved whatsoever).
 
The wrong kind of cable.

Battery packs are usually welded together with little bus bars. If you've ever tried to solder onto a battery then you know it's extremely difficult to get a reliable connection with solder onto those plated steel ends, especially if the packs are to be used in a high vibration environment like a drone or ebike.

look more like 18650 lithium cells at 3.7v, wired in parallel for a total of 3.7v. The issue here is current - 18650's can output 20A easily, so those wires have to handle 60A. Saying that they look quite thick, should be OK

if all you are drawing down from the batteries is 1A the wire you are using in the photos will be perfectly good.
