Berlingo rapid battery drain

I'm experiencing a persistent electrical issue with my 2014 Citroen Berlingo electric (225463 km). The battery seems to be discharging heavily, with an error message in the speedometer, weak/flickering lights, an error stored in memory, and weak starting performance. Has anyone encountered a similar rapid battery drain? I suspect a defective battery sensor.

Sounds familiar. I had something similar happen with my Berlingo. Did you check the battery terminals for corrosion?

Terminals are clean. I measured the voltage drop across the battery with the engine off and on, and it's within expected parameters. This makes me think something else is drawing power, or the sensor is reporting incorrect values. Did you have the same error messages?

Yeah, same error messages. For me, it ended up being something the workshop spotted pretty quickly. Might be worth getting it looked at before it strands you completely.

Thanks for the confirmation. I took it to a workshop and it was indeed the battery sensor, as suspected. Repair cost was 315€.
