you can use the BM2 voltage logger for long term logging. (fitted on van)

but will need a clamp meter to find what circuits are draining power (an auto electricians tool)

Clamp Meters
Any recommendations for clamp meters? They have been mentioned in a few threads but I can’t find suggested products. Suitable for small mA measurements with dc in the van and elsewhere and also if possible up to mains ac. I’m not sure how much I need to spend for a tolerably decent one with the...

Initialy i thought the victronenergy shunt looked a good option. reading the install guide, it says that no other connection should be hooked up the battery neg term. Does this mean it cant be used on a bttery insitu in the van?start here:

Also, not being an electrician at all, I dont know what the connection to other end of the shunt is too.
It's not advised to add a Victron shunt to the vans starter battery as VW already have one on it.... (It's on the NEG battery post)
Can I use the VW one to display readouts etc. add bluetooth?
No, unfortunately not.
Hi guys,
I've had a battery drain on my T6 Velle. I think we found it, and was a simple fix. I've got adaptions on her as I'm a wheelchair user and it appears one of the adaptions was adjusted wrong, it was permanently holding the auto gear lever button in and therefore keeping things alive (conclusion of the auto electrician from the adaptions company), does this sound plausible guys???
I have a BM2 battery monitor on the battery, I'll try and attach the screenshots to see if it's draining too much still or is it normal now??? Cheers all.

dont worry so much about the instant voltage reading. . .
you need to look at the drop in voltage over time. . .
post some pics of your 1,3,5,7,15 day voltage plots. .

Battery Monitoring -- How I Done It --
Hi, Could someone give me a second opion on my battery. Its a 105ah Expedition plus, installed in Nov 2020, charged using a ctek 250se. Everything was working okay but i have noticed it behaving a bit strangely on the charging front. when driving the logs are showing that it is going to...

This is an older 15 day voltage plot mate...
And the latest...
I was away till the 19th so she was parked up in an airport car park. When we got back there wasn't enough in her to start. Which I already new it wouldn't, so I had the NOCO on hand. I had the auto leccy guy out then on the Monday the way 20th, and he thinks we've sorted it (he's said that before though).
Last 7 day plot...
And last day...
Cheers @Dellmassive as usual would've been nacad if it wasn't for yours and the other guys on the forum help and advice!

This was yesterday's full day...
I think it's definitely better if not sorted. I have a new larger battery ready to put in her but don't want it in till I've sorted the drain. I'll always have slightly more than an average T6 because of the adaptions I have, hence why I'm putting the better starter battery in!

its looking much better. . .
the starter battery should stay above 12.00v for at least 3 weeks, possibly longer.
you previous plots show an issue with the starter battery dropping bellow 12.0v fairly quickly.
....
BUT NOW STAYING WELL ABOVE 12.0V - SO much better.
...
yesterdays full plot shows the marked improvement. . .
.
now keep using the van . .
then post a 7 day, then a 15day plot.
but looks like your issue is solved.

Cheers @Dellmassive you are an absolute legend! Thanks for your help pal! It's been fecking stressing me out, this is a big relief! I know how to keep an eye on it now too thanks to what you've just showed me! 
After 3 trips to 2 garages and 2 months later I finally have a fix for my battery drain.
A faulty unit on the sterio/ reversing camera screen (located immediately behind the screen). Apparently it was faulty and was keeping the media unit live and preventing the van from shutting down all its ecus. Easy 5 min job to replace.
Battery draw at rest is now 0.07Amps. Tracker and dash cam still running.

Great news @Pidsley you're a bit relieved to have sorted then too! Strange how these small things can cause so much stress! You deserve to put your feet up and have a cold one now pal!
Hi @Dellmassive here are some more data images...
7 day... Loads better but not sure if it would last 3 weeks above 12v if I didn't use it?! Do you think I should put the new bigger battery in now and see how it goes? Or???
15 day plot...
its looking good for now.
staying above 12.0v
looks like the longest its been left alone is 1.5 days. ( not even a long day weekend yet)
so id say keep going as you are. . .
see how is goes over 4 days, then 7 days of no use.
all being well it should last 3-4weeks . . . . . and still restart
( though i would expect the voltage to drop slightly below 12.0 after that time)

Well guys it was definitely the incorrect adjusted adaption to the gear lever which was causing the battery drain.
We went away for a week and she started up just fine when I got back! Really relieved, thank you all hugely for your help! Especially the main man that is @Dellmassive I've also now had the bigger battery put in and that's improved things too, the wheelchair lift is now slightly faster due to the new larger battery! Happy days!
Thanks guys!!
