is this what you are looking for? not sure if you can get it in 2 days, but try looking around on amazon. search for hailong base 5 pin or 4 pin. you can also find just the connectors themselves. the connectors can definitely handle 30 amps. i dont have a hailong but i have a similiar battery with the same pins and i run 40 - 50 amps through it fine. they get a bit warm but thats it.
