You cannot add the large display from Yunli on these controllers. 

You are buying a part depending on your choice, as pictured. We have added a complete set with QS-S4 throttle display, at a discounted price, if this is what you are after.

Introducing the newer generation of Yunli controllers with these 72V/60A Yunli set controllers easy replacement, Sinewave FOC (18 Mosfets).
Designed to make your life easier and cheaper to maintain your electric scooter. You can very easy replace a faulty controller yourself as you don't need to unplug all the cables anymore, you jus need to disconnect the motor, battery cables and the plug that hold all other cable together.
