Tsdz2 x-18 display battery

[didimralbert]

I wonder if someone can help me out. I'm a little bit of a novice at this. I recently converted a pedal bike, please see photo, I've got a 2020 tsdz2 with the X-18 display. I'm using a naked battery with my own case that I strap to the front rack (not pictured). The issue I'm getting is that the X-18 battery indicator always shows full. Everything works and the bike rides nicely but I've been riding it for a while and I can't believe that it's still full. I had issues with the battery indicator on another conversion and changing the battery voltage resolved this but X-18 does have that setting. Any ideas? Should I just change the display?

Most battery indicators are quite dumb and just give a rough guess based on the battery voltage. You X-18 battery indicator is likely programmed for a lower voltage battery, so the "full" bars never decrease because the voltage hasn't dropped to the level it is expecting. I'm not sure if the XH18 display can be programmed/changed to set the correct voltage for your battery pack. You can try searching for "XH18 display manual".
