I’m not sure about those specific ones, but I have gotten cheap Chinese ones and more expensive ones (from mylipo.de) and the differences between those are:
Flexible silicone wires
Bit thicker gauge
Reinforced connector with some sort of glue
Tough non silicone wires (annoying to solder because the plastic melts)
Bit more thin (less current?)
No reinforcement (means the wires get pulled out the connectors more easily)
I prefer to use the expensive ones but I also have a lot of spare cheap ones because why the hell not get a pack. I reinforce their connections with hotglue myself. Can’t say I notice any difference in performance because of the thinner wire. The expensive ones are more convenient to work with mostly. (in my experience)
Check the reviews, they usually say whether they are silicone wires or not. And just get a pack of cheap ones anyway, they always come in handy IMO.
*Especially the cheap male ones, for converting other batteries for example.
*just noticed the more expensive ones say silicone wire in one of the pictures
And of coarse MMW has good ones for cheaper:
