A battery monitor which measures voltage also known as a voltmeter, and a battery monitor which measures volts and amps more commonly known as a battery monitor.Ī voltmeter can be a very simple solution which can measure the current voltage of your battery. Do I need a battery monitorīattery monitors for rv’s and van conversions come in two forms. This shunt is the core brains of the battery monitor and is what the user interface panel is plugged into.Ī voltmeter can be referred to as a battery monitor however it lacks some important functionality, so this post generally doesn’t refer to voltmeters as a battery monitor. It requires all grounded wires to ground on a shunt which is then connected to the negative terminal, while no positive interception is needed and a connection is made directly to the battery. This applies to both AGM & Lithium ion batteries the core difference being the maximum level of discharge you can go to, 50% for AGM and 80% for lithium ion.Ī battery monitor with ammeter functionality measures the input and output of a battery by analysing the current flowing in/out of the positive and negative terminals. Battery monitoring in a van conversion is really important as discharging your batteries too much can lead to damage. It also monitors battery history and the number of cycles a battery goes through.
So apologies in advance for any obsessing over the power your solar panels are generating or how much power 30 seconds of hair-drying actually uses! What is a battery monitorĪ battery monitor is a device which is able to tell you detailed information on load and charge of a battery.
If you’re anything like me you’ll love staring at this piece of equipment.
