Yes you can install a battery monitor in a van conversion, rv or motorhome which already has an electrical system. TurnRaise Waterproof Dual USB 4.1A Charger Adapter and Voltmeter LED Panel 12V-24V for Motorcycle Car Boat Marine Carvan Can you install a battery monitor in an existing electrical system? Here are some of our recommendations if you’d like a simple voltage reading. Our recommendation is always to install a battery monitor with an ammeter reading functionality. Batteries are not cheap, you could be costing yourself hundreds if not thousands if you’re not careful. In our opinion this will also leave you prone to causing some damage to your batteries. This could mean that you miss a fault and you run out of power far faster than you expect. The issue is that this reading has no context of the current draw on the system or whether the system is actually being charged, either by your alternator or solar panels. All they require is for you to know the ranges of the state of charge of your battery type. These are simple and cheap like the one in the picture. 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.
