Hi,i have built a pandaebike setup, but after riding for about 25 miles the battery gauge still says full on the display.They are not replying to my emails and was wondering where i can buy another one with a speedo function as well.

Maybe you don't need to buy another one. What one do you have. Many have an adjustable damping factor which can make it change too slowly. It can easily be changed.

That's a Li Shui controller. I'm sure they use to use KT. That complicates matters a lot. I would guess that any Bigstone or Kingmeter LCD would be compatible, but I never tested that.

Ok thanks very much

Panda some times are in the habit of posting a pic of incorrect items, the OP should confirm whether his controller is a LSW or KT as rightly said they usually use KT.

 

The controller label will confirm one way or the other rather then rely on a pic that may be wrong.
