LFP battery discharged to ZERO volts
Question: I have installed a LFP battery in my car. But when I came today to the car, the car was completely dead and all electronics stopped working. What is wrong?
Answer: What you describe may happen with the car. When the car is parked, over some days, then some equipment will discharge the battery to complete emptiness (full deep over-discharge).
This may happen when the small “inside” lamp is by mistake left “on”, or when the door is not closed properly.
It may also happen that the radio was left “on” – but silent, or some other equipment drained the battery (e.g. alarm system that turned on for some reason).
In some cases the driver may accidentally forget the main headlights on, and the battery will be depleted just in a few hours.
