Battery Monitor. The essential piece of motorhome kit - based on a smart shunt.

Keeps you informed with what is going on with your leisure battery - State of Charge and current drain/charge

A number of makes are available.

If you have lithium, you will need it, and treat it as a fuel gauge for your battery.

Such a simple, but brilliant explanation.

Also known as a 'Coulomb counter' because it counts the Amps in/out over time.

Electric Charge is measured in amp-hours, which is the total amount of electric charge that flows when a current of 1 amp flows for 1 hour.

The amount of charge that flows when a current of 1 amp flows for 1 second is an amp-second, which is called a Coulomb. That's the official unit of electric charge used in scientific circles.

The practical unit of electric charge is the amp-hour, which is 3600 amp-seconds. So one amp-hour is 3600 Coulombs
