Thread: Love this remote Bluetooth battery monitoring

Brian, or anyone with a D4. Does the negative terminal come from the factory with the ability to connect other cables to it? In my D3 all negative wires are grounded to the chassi. You can’t attach anything extra to the neg terminal.

I went to Supercheap yesterday and got a monitor. Good bit of kit.

Also found I wanted to check batt volts one night after I’d jumped into bed as I wanted to run a fan all night - easy as.

For overnighters I don’t even give batteries a second though....

If the car is parked up for the whole day with solar....again I don’t even give a second thought.

If it’s cloudy/raining and I’m parked up all day I start to think about checking...

Oh, I only have 1 aux and it separates from the starter as soon as I kill the donk....only run one fridge and one led light strip.....

Hang on....about to install a travel Buddy Oven......nah still won’t be overly worried.

Agreed, I don’t check mine one short stays, but depending on what I’m doing and what the weather is like I do. My van runs a 90 litre Engel 24/7 off its batteries even when I’m not using it which the batteries cope with fine, but long stays, overcast weather, heaters, tv’s, etc will see me keeping an eye on them.

Yep. Got my eye one too. Nothing like a hot pie for lunch. Where are you thinking of putting it? How are you going to mount it?

Er whoops, just noticed this is a D3/4 thread......

Mine is going above the fridge and accessed through the gull wing on he defer

I’m actually giving it a run tonight for the first time, on the bench in the garage.

But multi-meters don't have an alarm on them. I've got a visual gauge inside the camper, but as Gav said, it's only good whilst the campers open. I also like the history, but I'm because I'm a nerd and an analyst

Not sure if I'll bother using the other 2 in the Defender - I can already see one battery's voltage on the Madman gauge. Probably palm them off to someone else if I don't use them.
