4S+4S into 8S LiPo Series Balance Lead?

Hey !

Do someone find this exact wire elsewhere ?https://www.overlander.co.uk/lipo-balance-series-lead-4s-4s-into-8s-pack.html

I have 17£ shipping to France on this one and for a 3£ product it’s not the best deal lol


I may also be able to weld it if needed but I don’t really well understood the series wiring of thoses …!

Thank you !
