Car battery monitor
The lead-acid battery forms the heart of the electrical system in any car. If you are on a camping or caravanning holiday, it can happen that the battery is discharged so deeply by extra loads that the amount of energy left is too small to start the car. The car battery monitor described here prevents this problem by disconnecting extra loads in time, ensuring a battery condition which is always good enough for a reliable engine start.
