Old thread. But I was just wondering if you know what would be the max length I could extend the unit too? Thanks if you see this.I was just about to make a post to say the Cables on these Aili Meters are rediculously short (500mm compared to the 10M or Longer ones on the Victron BMVs).
Not found a source for the plug and socket connectors, so what I usually do is modifiy the original one to insert an extension length as the extension cable you can buy is way too pricey for what it is.
I don't know, but I can't see any reason why it can't be as long as you need within the confines of a motorhome.Old thread. But I was just wondering if you know what would be the max length I could extend the unit too? Thanks if you see this.
if you have the Batteries as a single bank, you have the two -ves together and the two +ves together. Then if you connect the Shunt -BAT to one of the -ves (and it is the ONLY thing connected to the -ve apart from the other battery of course), then it is monitoring both batteries as a combined bank. And you set the capacity in the monitor to the total of the two batteries.Hoping to resurrect this very informative posting.
I would like to monitor my own batteries using either the Victron Bluetooth shunt or the Aili wired display version as recommended by Wildebus.
Before I make the final decision, I just wondered if having two batteries in parallel could mess with the readings? I assume that the current will always flow from the battery with the greatest voltage?
Would it be more accurate to have a monitor/shunt on each of the batteries?
Thanks for confirming that David.if you have the Batteries as a single bank, you have the two -ves together and the two +ves together.

You could have a monitor on each battery if you wanted. not a lot of point unless you are curious about how each is working. Bear in mind these are Monitors only and have no effect on how the batteries are actually used.
(FWIW, I have a Victron BMV on one bank, another on the other bank and a third on the overall bank as a whole, but I don't have the typical setup )
Also .... at the original date of this thread, the Victron Monitors were a LOT more expensive. Right now they are a lot cheaper and I would recommend Victron rather than the Alii Monitor now the price difference is a lot closer.
The Smartshunt is probably the most popular Battery Monitor as it is so simple to installThanks for confirming that David.
The idea of a simple connection and no wiring as its Bluetooth gets my vote.
Are they still available through yourself?
I have 400w on the roof and Renogy b2b mppt controller( keeps SB topped up )I find it hard to understand how some people manage ok in winter with solar my batterys go one way down
34Ah per Month? You are generating in one month 1/6th of your battery capacity. if that is sufficient, you could go without any solar for 3 months and still not be down to 50% discharged.I have 400w on the roof and Renogy b2b mppt controller( keeps SB topped up )
every time I've looked LB &SB fully charged (220 Flooded lb) according to app circa 30/34 ah per Month Is it a case of the sun shines on the righteous ?(or just Lincolnshire)
No not a typo.did actually get as high as 44ah in December,guess I must have switched something on briefly,so. IF the app is accurate just over 1 ah per day,when nothing is on leisure side and engine side is is on life support and 3 batteries self discharge.34Ah per Month?

34Ah is a tiny amount of power in a month - that is around 13Wh per day - you couldn't run an LED light on that for more than maybe 2-3 hours at the most.
I suspect the 30/34Ah a month might be a typo? (my fridge uses more than that every day ).
Just checked my numbers and last month was a touch more than sunny Lincolnshire at 1430Ah (or 17.27kWh). Sadly still not enough to run the fridge, but the weather has been pants everywhere
I don't know if you are mixing up Ah - Amp Hours - with something else, but seriously 1Ah a day is a tiny tiny amount - 12 Wh (Watt-Hours).No not a typo.did actually get as high as 44ah in December,guess I must have switched something on briefly,so.

Would like to double check with meter on starter battery only at some point as this seems on the low side (but shows fairly consistent month on month) ,even if 20% inaccurate still wouldn't make much difference . What would you expect ? Bearing in mind lb isolator is off.
No irony or sarcasm intended,having read many posts about SB going flat in storage ,I obviously wrongly assumed this was what was being referred to.I don't know if you are mixing up Ah - Amp Hours - with something else, but seriously 1Ah a day is a tiny tiny amount - 12 Wh (Watt-Hours).
Turn on an old fashioned electric light and you will use 12Wh in 10 minutes.
I would expect the residual drain on the starter battery to easily exceed 1Ah/Day.
When you quoted a post from Molly which said "I find it hard to understand how some people manage ok in winter with solar my batterys go one way - down" and described your experience, I had kind of assumed you were referring to a motorhome that was actually in use, and not one that was in storage with the Leisure Batteries isolated and not in use
I guess I must be missing some kind of irony or sarcasm?
Sorry should have been replenishing what was used during hours of darknessNo irony or sarcasm intended,having read many posts about SB going flat in storage ,I obviously wrongly assumed this was what was being referred to.
Also just thought the numbers I'm seeing. could they be what has gone into the batteries and be what is being replaced during hours of darkness,whilst drain during daylight is not captured ??? as it never enters the battery,
sounds unlikely to me but would it be possible?
The difference in readings between a full day and when dark is a good point. It depends how the device you are reading the info from is using the data and the difference could quite literally be night and daySorry should have been replenishing what was used during hours of darkness
