Twizy Weak Battery and Flickering Lights

Twizy eh? I had similar issues with mine. Weak starts, lights dimming... was your battery charge also acting up? Like, showing full but dying quick?

Yeah, the battery charge indicator seems unreliable. It shows full, but the battery drains fast. What fixed it for you?

Sounds like the same sensor issue. I ended up having to replace it. Honestly, just take it to a workshop. They'll diagnose it proper, but I'm betting it's the sensor.

I took it to the workshop. Replacing the battery sensor fixed it. Cost 315€. Thanks for confirming my suspicions.
