Generally, if your battery and wiring overheat it is because you are drawing more current than they can handle.
What size wiring are you using?
What type of battery?

Well your wire is much too small if it is 1.5mm including the insulation.
I personally don't go smaller than 18 gauge wire for my motors.
It also sounds like your lipo battery doesn't have a high enough discharge rate if it is getting too hot.
