What a great, straight forward, uncomplicated, easy to follow, no nonsense video explaining exactly what i need to know, how to connect it and how it works. Thank you!
Perfect, quick tutorial. Great! Those Smart shunts are probably the most important product of every battery bank and work flawlessly. For a victron product, they are relatively cheap aswell. Together with their chargers, which are not cheap but highly configurable you own equipment that is versatile and good for decades. Thx for the video!
Thanks for answering my question in an indirect way. I disconnected my battery from the smart shunt to remove an unused monitor wire. My battery is at 42% SOC and has been since I parked my boat for the Winter. Every time I checked it, it was consistently at 42%. When I reconnected it shows it is 100% SOC. I understand from your video that it will reset after I fully charge it. Thanks for the info!
Another great tutorial. I purchased all the gear for my little set-up (One 206, charger, and Shunt) from you. After watching this video, I hooked everything back up (Battery was disconnected and stored indoors for the winter) and started to match the settings on my phone, then realized you must have already done that for me before mailing the shunt. Thanks
Question, On the "Charged Voltage". The booklet I got with my battery. States 13.5 volts is 100% soc. Also it states Charge at 14.4 - 14.6 volts. So do I fill in "Charged Voltage" with 13.5 volts or 14.4 volts.? Thank you for your time and videos. Yes I have the Victron BMV-712. The battery is a LifePo 190ah 12 volt
You went over making-using insulated tools when working on batteries as you should in any high amp circuits, but it looked like you were wearing a metal ring. I made the mistake of wearing a gold wedding band to work. I arced the band between the cable and battery post. Gold if an excellent conductor of electricity and gets real hot, real fast around a tender part of a finger, plus it did major damage to the ring.
We will insulate it for next video. It's a hair too small for taking off every time, and nobody wants to forget it at work and get in huge trouble at home!
Just put one of these on my 5th wheel a week ago. Great tool to let you know what's happening with the battery. My only complaint thus far is I can't get more than 10 feet from the front storage and the app loses its connection with the shunt. The only place inside I can connect is in the front bedroom, as soon as I walk down the steps to the kitchen, the app loses its connection with the shunt.
at 6:55, what do you mean by "if your battery is at 100% you should do a full recharge cycle"? it is fully charged so how do i do a full recharge cycle with a fully charged battery? what does that mean?
Thank you sooo much!! just what i was looking for! Been looking for an hour watched like 10 videos none as clear and on point like yours!! You are the man!!!👍👍
what is the minimum voltate that this shunt will operate ? for example a mini victron mppt 100/20 only works until battery voltage drops under 5V, then its stops showing anything even vired to cerboGX
Thank you for the video I have some questions as I bought this device but I'm retrofitting it into my lead acid battery system with three Banks now my negative and my positive cables from my battery are of equal length so I'm assuming since I have to connect this device to the terminal and then to the cable that I have to cut out the length of the shunt to keep the battery cable equal length looking for confirmation am I correct and thank you and of course I'll have to cut and I'll have to cut the positive cable the length of the shunt
So when it comes to having solar hooked up to this. Where do the leads go? Does the negative side coming from the solar panel go before the shunt or after?
I have a question...I have two lithium batteries and an inverter. The negatives for both batteries and the inverter are attached to a bus bar. How do I wire in the shunt?
I’m using the smart shunt for my RV. I have one LiFePO4 battery and a GoPower 190W solar panel on the roof paired with the GoPower controller. The issue is that as soon as the sun comes out in the morning the shunt thinks the battery is fully charged. What should I do?
Is the setting the same on sok's 200ah battery? And why is the charged voltage recommended 13.8v when on the side of the case it says 14.6? I don't know is why I'm trying to understand.
Great video however, as a professional pipe fitter, I have very limited knowledge of electrical circuitry and could use your advice on a project of mine. I am attempting to build a portable power supply and will be limited to complete it due to budget constraints. I have the box for equipment, a 12v 100amp LiFePO4 Battery, a charger, a few fans for cooling with thermostatic control and thanks to your video, I will be purchasing this shunt. my question is, where do those red and black cables (I assume power out) go? I am only trying to power a 12v dual zone fridge for now. Let me know. Thank you.
Thanks for your shut set up video Do you need I have 2 of these shunt monitors As I have 2 x 12v lithium lifepo4 batteries in series for my 24v invertor?
How do you connect positive and negative wires with shunt when you have four 12v 15ah batteries in parallel? Do I connect positive on, let’s say, battery 1 and connect the negative on battery 4?
Ok so it needs to be the only thing connected on the negating post. So when I have batteries connected in parallel can it be attached to any of the negative posts or preferably the last one?
Question...my Victron shunt is connected to my 36v lithium battery for my trolling motor. Whenever I power off my trolling motor or when it goes into power saving mode, the Victron shunt resets itself to 100%, even if i do not charge the battery. How can i prevent this?
does every single ground on all of my devices/lights on my vehicle have to go to the shunt negative? will the calculation be off if i use chassis ground for some things?
Thanks for the video! I’m using my 12v 54amp hr lithium battery for a trolling motor. I’ve installed the shunt and followed the steps on your video but the battery percentage never seems to drop. It just stays at the percentage I set as the state of charge. Any suggestions here? Thank you so much. Would love to get this fixed.
I may not understand the use of the Smart Shunt.......Do you need one if your using a BMS with bluetooth and it's app to set and received all the informations you showed us on your smart phone? Thanks Much....
Does the victron smart shunt use both SOC and Tail current data inputs for better accuracy? If clouds go over head for a moment on solar panels, seems this could throw off Absorption time detection, and trigger another cycle inadvertently.
Is it ok to run my vehicle chassis grounds (engine block, firewall, and fender) to system minus? I’ve had mine wired this way on my Jeep for several months now, and haven’t had any issues. Someone recently pointed out to me that it might be dangerous and now I’m doubting myself. I have a Jeep TJ with a non-smart alternator and 4.0L engine.
I have 2 12 volts in series and added a battery equalizer (watts2470 directly to the batteries..will this still allow the Smart Shunt to work properly?
I have two 7Ah 12v Sealed Lead Acid battery connected in series in my Cyberpower battery backup which the two batteries no longer hold a usable charge. Can I switch out the Sealed Lead Acid batteries for these Lithium batteries or do they have a different charging cycle mechanism which makes them not interchangeable? Thanks!
Two Battery Banks with a Switch (A Battery Bank, B Battery Bank), One 2000/4000 Watt Inverter with a 200 Amp Circuit Breaker, One Victron 500 Shunt. How do I set this up? Do I need to use a Negative and Positive Bus Hook up? Do I need two Victron 500 Shunts? I also want to use a single Victron 100/30 Amp Charge Controller to charge the exhausted Battery Bank while continuing to use the other. Most of all, can I keep track of everything with the Victron Blue Tooth Application?
I just bought one of these batteries and it has Bluetooth but there’s no app out there to show me the battery percentage I have to buy something to add on to it to see %?
What is the aux port for? I have 2 x 150Ah lithium batteries wired into one big bank, do I need to connect my second battery up or is it for something else?
Awesome video, thank you! I’m a little confused on my rv installation though, I have a wire that goes from the negative battery to a chassis ground. Do I leave that where it is or does that have to move?
Hi I am curious how do you know that these settings are correct since the SOK battery speck sheet doesn't match most of the field names on Victron's setup screens.
We've tested operation with these settings in-house for nearly 2 years now, and have hundreds, maybe thousands, of customer installs with these exact settings that have no faults. On the flip-side, we have had multiple customers use the default settings on various spec sheets and run into many issues with inaccurate SOC% and trouble getting the shunt to synchronize to 100%.
thanks for this video.i have AGM battery for my boat electronics, is setup pretty much the same.?also you didnt mention the load positive side ,do they all go on just the positive of battery? thanks john
Positive side is wired as you normally would. But it best to have one cable. A good installation would have all the positive cables leading to a correctly sized positive busbar and then just one cable from the busbar to the battery. Its not good to stack too many lugs on the battery terminal. You tend to not have good electrical connectivity doing that. The reason you don't want to add other negative cables to the battery side of the shunt is that the current passing through that cable would not be read by the shunt. You'd thus get erroneous readings. You want all the charge and load currents to pass through the shunt which then gives you correct readings for state of charge. Again, like I said about the positive cables above, put all the negative cables on a negative busbar and then run one cable to the load side of the shunt you are good to go. Then you will get very accurate state of charge and total load readings and have a very neat, clean and electrically well-connected installation.
I have 2 banks of 6 eg4 batteries (not LL). Needing a wiring diagram to connect my 500A smart shunt to them. Banks are parallel to parallel. Pairing off on the two negatives. Do I need to buy two smart shunts? One for each bank? Thanks.
If you want to monitor your entire battery system (both banks of 6) then you just need 1 and make sure both negative cables are connected to the single battery side bolt on the shunt. You just need to make all negative connections goes through the shunt.
It's to minimize the chance of an accidental *conductive* short circuit between the terminals of the battery. 100s or 1000s of amps of current could flow unexpectedly. All kinds of bad things can happen in that state.
I only know that the shunt supports series. I have two 24 V as series in an 48 V system, and the shunt can measure voltage and mid-voltage. For parallel you could use the shunt like you have one big battery, but there could be issues with different loads in those two batteries, which could slowely kill one of them. This is why I try to avoid it and separate my systems (2*2,5kwh with one 3kW inverter with 2,5kWp of solar)
Good video, thank you that really helped me. Can I ask if it's Ok to run my campervan alternator smart charger + solar charger through the smart shunt? Or do I need 2?
It's not charge voltage, it's chargED voltage. If you set to 14.4, then by the time the voltage gets here, it's too late - current already starts tapering down, so the tail current threshold never is met.
I managed to forget to set the SOK battery SOC to 30% as mentioned before charging for several hours. It is not at 13.4v. How do I go about getting an accurate state of charge from here? Will they not reach 100% because the SOC indicates 100% even though its below that? Also, it doesn't indicate my time remaining with current load unless I turn of the solar disconnect switch for some reason? Hopefully someone has some insight for these things.
The only thing confusing me is you put 13.8v charged voltage!! So is this if not used off grid? If using solar doesn’t this need to be 0.2v under the absorption voltage or is that wrong? I was told to have in the mppt 14.5v absorption but in the shunt charge voltage at 14.3v 🤷♂️ help pleaseeeeeeeeee lol
If used on grid or off grid, it doesn't matter...It's for the battery. The manual says 0.2v under absorption, this is good for lead-acid, but since lithium doesn't need absorption, it's too high of a voltage for the shunt to properly detect whether or not the battery is full, because they battery doesn't spend much time above this voltage. We have had in-house tests cycling daily for over a year now...the settings outlined in this video are flawless for the greatest majority of LiFePO4 batteries.
@@CurrentConnected ok thanks so 13.8v charge voltage on the shunt . So is this even if using 14.4v or 14.5v for solar mppt in bulk is that ok ? I get what you mean it’s setting for lead at 0.2v below absorption So do you forget that when using lithium
I wonder if you can somehow set an ampere limit for charging in the smart shunt. I know that’s a somewhat specific question, but maybe someone has an answer: I would like to charge a battery with two victron solar chargers, which charge a battery through the shunt, which should be charged with a maximum of 20 A. Do I have to limit both chargers to 10 A each so that they do not exceed 20 A together, or do the devices Talk to each other? Or can i Define that in the shunt? (I ask because I read that when a shunt is used, it takes over „control“ of the charging network - At least when it comes to measuring the battery voltage)
Current, one final question: Because I have two of the 206Ah batteries, do I want to specify a total of 400Ah or actually put 412Ah? These batteries were purchased from you (through Amazon) actually, so thanks for getting them shipped on-time!
Thanks for this video! I just received me SOK batteries (206Ah x2) and will use these settings, but do have a question. They WERE shipped so I assume they're at the 30%, however, should I use 13.8v as the charged voltage or use 13.1v which is what me Multimeter shows on both? I want to be sure it's as accurate as possible. Thanks!
Always use 13.8v on the shunt. Those are at 30% charge right now...also, once you fully charge them it calibrates the shunt to 100%, so even if you are not set at exactly 30%, once you reach full charge, it will be accurate.
The shunt is essentially just the sensing device, and does not contain any relay/contactor that can disconnect power. If you connected it to a Cerbo-GX, you can use SOC or voltage as the criteria for dry contacts / alarms.
Thank you. Victron’s guide was a waste of time but I got through everything using your video.

14.6 is what it charges to and resting is 13.8 after charge.
What was the other wire? A temperature probe? Is there a way to measure and set a low temp alarm?

Where would the shunt go if you have to SOK lithium batteries next to each other on a fifth wheel?
WHat happens if you have multiple batteries in Paralell and another earth point on another battery?
thats what im here for. im assuming when you set the proper amp hours you should be good. voltage stays the same in parallel
does a shut have a useful purpose on agm batteries?

Not knowing what have makes it impossible to to answer.
Are your battery settings good for all 100AH LiFePO4 Batteries?
How many neg wires can you connect to the vitron terminal
When do I need a buzz bar
You can easily fit two. Past that I would use a busbar and then have single connection from the busbar to the shunt.
So should I put my shunt in between the dc charger and the battery? Or between the battery and inverter? Thank you
ANYTHING connected to the battery negative first goes to the shunt then the battery like is shown in video.
Not sure what the point of insulated tools if you touch the battery post anyway?
It's to minimize the chance of an accidental *conductive* short circuit between the terminals of the battery. 100s or 1000s of amps of current could flow unexpectedly. All kinds of bad things can happen in that state.
My system went back to default. How do I increase the battery capacity from 200 to 600? Thanks

Quick question. Do I need two shunts if I’m running two batteries in parallel or just one between the two?
Just one shunt.
If I use clamp style charger for my SOK do I put the negative clamp on the out side of my shunt?
Yes, it must be, otherwise you will totally throw off your SOC reading.
Hello! A very good tutorial! Thank you!
Do you have any idea how to set a maximum load limit? For example 90% or 95%, to protect the battery?
So if I have 2 - 200ah batteries connected in parallel, I assume I would set my battery capacity to 400 ah?
Yes, exactly! When batteries are connected in parallel, their Ah capacities add together.
Good video, thank you that really helped me. Can I ask if it's Ok to run my campervan alternator smart charger + solar charger through the smart shunt? Or do I need 2?
Why do you recommend 13.8v as the charge voltage (as opposed to 14.4)?
It's not charge voltage, it's chargED voltage. If you set to 14.4, then by the time the voltage gets here, it's too late - current already starts tapering down, so the tail current threshold never is met.
I have 2 100 ah hour batteries. How do you do those?
Do these only hook up to 12v. Or can it be hooked to 48v.
Any voltage up to 70v
Where can I get a chart for battery charge percentage.

Will the smartshunt work with all lithium batteries? Even the less expensive one like ampere time, or others?
Yes, it's programmable to work with any lead, lithium, agm, etc.
I managed to forget to set the SOK battery SOC to 30% as mentioned before charging for several hours. It is not at 13.4v. How do I go about getting an accurate state of charge from here?
Will they not reach 100% because the SOC indicates 100% even though its below that? Also, it doesn't indicate my time remaining with current load unless I turn of the solar disconnect switch for some reason? Hopefully someone has some insight for these things.
The only thing confusing me is you put 13.8v charged voltage!! So is this if not used off grid? If using solar doesn’t this need to be 0.2v under the absorption voltage or is that wrong? I was told to have in the mppt 14.5v absorption but in the shunt charge voltage at 14.3v 🤷♂️ help pleaseeeeeeeeee lol
If used on grid or off grid, it doesn't matter...It's for the battery.
The manual says 0.2v under absorption, this is good for lead-acid, but since lithium doesn't need absorption, it's too high of a voltage for the shunt to properly detect whether or not the battery is full, because they battery doesn't spend much time above this voltage.
We have had in-house tests cycling daily for over a year now...the settings outlined in this video are flawless for the greatest majority of LiFePO4 batteries.
@@CurrentConnected ok thanks so 13.8v charge voltage on the shunt . So is this even if using 14.4v or 14.5v for solar mppt in bulk is that ok ?
I get what you mean it’s setting for lead at 0.2v below absorption
So do you forget that when using lithium
@@MotorhomeDIY Yes. Exactly. Forget about the .2v below absorption, set it at 13.8 and it will work perfect.
@@CurrentConnected thanks for taking the time to reply 👍 very helpful you earned a sub . Great content
why did you do 13.8 for this battery?
May be a dumb question lol but if I have 4 12v lifep04 wired in series for 48v would the shunt be installed the same way?
Yes, the red positive wire would feed to the +48v connection. This is well documented in the instruction manual for the SmartShunt.
@@CurrentConnected thanks for the quick response I purchased this used and didn't have any instructions with it
Do you think using 10 gauge cable to run 40amp is a bad idea? Your guage seems to be 6 or 8
I wonder if you can somehow set an ampere limit for charging in the smart shunt.
I know that’s a somewhat specific question, but maybe someone has an answer:
I would like to charge a battery with two victron solar chargers, which charge a battery through the shunt, which should be charged with a maximum of 20 A. Do I have to limit both chargers to 10 A each so that they do not exceed 20 A together, or do the devices Talk to each other? Or can i Define that in the shunt? (I ask because I read that when a shunt is used, it takes over „control“ of the charging network - At least when it comes to measuring the battery voltage)
Are you sure it resynchronizes to 100% Maybe better to fully charge then set SOC to 100%?
Current, one final question: Because I have two of the 206Ah batteries, do I want to specify a total of 400Ah or actually put 412Ah? These batteries were purchased from you (through Amazon) actually, so thanks for getting them shipped on-time!
Accurate would be to set 412ah. Thanks for the support!
Does anyone make a product like this for smaller portable builds. I have a small 40Ah power box I built and would love something like this.
Thanks for this video! I just received me SOK batteries (206Ah x2) and will use these settings, but do have a question. They WERE shipped so I assume they're at the 30%, however, should I use 13.8v as the charged voltage or use 13.1v which is what me Multimeter shows on both? I want to be sure it's as accurate as possible. Thanks!
Always use 13.8v on the shunt. Those are at 30% charge right now...also, once you fully charge them it calibrates the shunt to 100%, so even if you are not set at exactly 30%, once you reach full charge, it will be accurate.
@@CurrentConnected much obliged!
No alarms? Or auto shutdown?
The shunt is essentially just the sensing device, and does not contain any relay/contactor that can disconnect power. If you connected it to a Cerbo-GX, you can use SOC or voltage as the criteria for dry contacts / alarms.
