Controller and battery have 2 different connectors, how do I connect them?

you could either get a new set of Anderson plugs to go on the controller side. BUT i would go with soldered ones rather then a crimp. or you can get a set of male and female xt 60 plugs if you still want to be able to unplug your power wires. OR you could even just cut both plugs off and directly solder the wires and heat shrink them. BUT for now if you even just want to be able to power the controller to make sure every thing works right until you can get new plugs. You could get matching bullet connectors that would crimp on. or you can even cut off the bullet connectors strip back the wires and then fold the striped copper in half and can just shove each wire into each of the Anderson connectors. for a temporary connection.
