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!
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!
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
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!
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.
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!!!👍👍
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.
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
My smart shunt never revealed state of charge accurately, but did monitor battery bank voltage very well. Either I erred in the connection process, or the shunt is defective, or both. The Bluetooth capability is awesome. After a fresh install to reflect the third battery addition, we shall have our answer. 3X 190 amp hour 12 volt lithium battery bank to supply onboard dc electric and inverter
Nice video, one super minor observation: you said we didn’t need the manual because you were going to show us everything, later you say make sure you torque it down correctly and to look in the manual to find out what that is… I’m just thinking… Would’ve been nice if you would’ve known what the Torque specs are so we really didn’t need the manual🤪
You may want to caution your users who see this video. Although you set the battery to 30% SOC in the Victron app at setup, that battery SOC is not stored in history in the app or the shunt. Therefore, once your users walk far enough away from the bluetooth range of the shunt and get disconnected, the battery may show 100% SOC the next time they reconnect to the shunt using the Victron app. This has been an ongoing problem for users like me, and many others, who do not use Victron batteries and a full Victron electrical system. I have a single 24v/200Ah server rack battery, the Victron 500A smart shunt, a Victron Lynx distributor, and a GroWatt Inverter/charger. The entire battery system works great, however the shunt "forgets" the previous battery SOC each time I disconnect from bluetooth. For example, if I manually charge the battery to 100% and sync the shunt to 100% SOC as well, then use 10% (~500 watts) of the battery capacity the shunt displays ~90% capacity remaining. If I then disconnect from the shunt's bluetooth signal (leave the van, or disable bluetooth) then later reconnect to the shunt again, the shunt often says my battery SOC is at 100% again - even though it is only at 90%. I believe the reason is that LFP batteries like mine hold a constant battery voltage until they are almost to zero capacity. The shunt sees the full voltage on the battery and believes it is at 100% SOC. The previous ~500 watts of usage I had consumed is "forgotten" by the shunt since I disconnected from bluetooth as I left the van. This is important for folks to realize, particularly if they have LFP battery chemistry not lead acid which decreases its output voltage as amperage flows out. You may want to try this yourself and perhaps do a follow-up video on this for your users. Good explanation about installing the smart shunt though. I do like the shunt for real-time monitoring of actual wattage flowing in/out as I am charging or discharging. I just no longer trust the SOC display the app provides.
Your comment is not true, SOC % is stored in the shunt itself. If you have "synchronized starts" enabled, your SOC will reset to 100% every time the shunt restarts, however with this disabled, even with the app disconnected and the shunt power cycled, the shunt will still retain SOC. The SmartShunt never uses battery voltage for capacity except for the "Charged Voltage". When the battery is being charged, and the voltage is above the charged voltage, it will wait until the current falls below the "tail current" at which point it resets the SOC% to 100%. If you have either charged voltage or tail current set wrong, then that would cause issues like you are experiencing. It has nothing to do with being connected or disconnected to the app.
@@CurrentConnected I want to believe that you're correct in your analysis of the shunt. For some reason, my shunt isn't playing nicely it seems. I have three screen captures from my iPhone over this past weekend to share if you would like to see them. I charged the battery to 100%, then started a discharge using my MaxxFans and 24v RV refrigerator. The first screenshot at 8:30am shows 99% SOC (2Ah consumed), then 86% SOC (27.9Ah consumed) at 4:45pm, then 80% SOC at 9:00pm (40.5Ah consumed), and the last shot is 99% (1.2Ah consumed) at 8:30am the following morning. I did not charge the battery overnight, and I do not have solar or DC-DC charging. Currently I only have AC charging to a 120V wall outlet from my home. The "battery starts 100% SOC after reset" is off. Happy to email or share these Victron screen shots with you if you would like to help me debug this? Thanks!
@@erwinvanasperen5353 yes, I believe so. Basically, be certain you fully charge the battery then set your 100% SOC voltage to a level just below the displayed voltage when the battery is full. My voltage was set about 1v too high so my battery never reset to 100% when it was charging. Now it resets to 100% SOC when full.
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?
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?
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?
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!
Do a video on connecting two Battery Banks to one Victron 500 Shunt, then to one 2000/4000 Watt Inverter. On the positive side, I also want a 200 Amp Circuit Breaker for the Inverter. I'm not sure how to connect the negative side for two Battery Banks.
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....
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.
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?
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?
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?
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.
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.
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?
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!
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.
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 %?
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?
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.
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?
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?
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)
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.
Perfect Video! Could you pleas explain whay you set Charged voltage to 13.8 volt. On my battery spec thath voltige is not stated anywere, my bms shut of at 14.6 volt and nominal volt 12.8 v.
Because that is the resting full charge voltage & float voltage for LiFePO4. Typically you won't get batteries full unless they are above this voltage, and the current drops down to 2% (the tail current setting). Any lower and you could get a false full reading and any higher you could risk not re-calibrating 100% properly.
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)
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.
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.
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.
One hint: When working on battery + terminal of a vehicle you better have the battery - connection disconnected. With this you avoid a short cut if you accidentally touch metal parts of the vehicle with your tool ;)
Thank you. Victron’s guide was a waste of time but I got through everything using your video.
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!
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!

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?
Same question.
It had to move to the other side of the shunt
I believe it's a 13mm instead of 14 mm. It's 13mm for my 206ah.

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.
Hi once I’ve done my settings and set my discharge at10% is that also when the alternator will start charging again?? Thanks Craig
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?
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!
Say I have 3 200ah batteries, does the red connector read the whole bank? Is that adjusted in settings? Please advise!
If I have two 6V batteries hooked in series, is the installation the same (on one side only, like on your video, or is it a different installation?)
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.
14.6 is what it charges to and resting is 13.8 after charge.
Do you think using 10 gauge cable to run 40amp is a bad idea? Your guage seems to be 6 or 8
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 %?
do u have to do anything different when u have 2 batteries connected in series
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?
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.
Hi lm setting 2 48 volts lithium battery what is the set up for those Thankyou
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?
What should my charged voltage be if I have a 206ah sok battery
My system went back to default. How do I increase the battery capacity from 200 to 600? Thanks
How do you know what percent your state of charge is? I got new lithiums and I don't know how I would know.
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
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?
is there a video on the victron battery monitor ?
Torque is VERY importent 😮😮 no its not.. just tight it, and all is good. 😊
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)
I have 2 100 ah hour batteries. How do you do those?
why did you do 13.8 for this battery?
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.
does a shut have a useful purpose on agm batteries?
Perfect Video! Could you pleas explain whay you set Charged voltage to 13.8 volt. On my battery spec thath voltige is not stated anywere, my bms shut of at 14.6 volt and nominal volt 12.8 v.
Because that is the resting full charge voltage & float voltage for LiFePO4. Typically you won't get batteries full unless they are above this voltage, and the current drops down to 2% (the tail current setting). Any lower and you could get a false full reading and any higher you could risk not re-calibrating 100% properly.
Good video
Glad you enjoyed!
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.
Will a 24v setup (with 2 serial connectected Sok batteries) give all the same parameters x 2? Thanks for you your information.
Only the voltage parameters get multiplied by 2. Everything else like efficiency, peukert exponent, tail current, etc.. stays the same.
@@CurrentConnected Thanks, you've helped me a lot with this information. Good Luck!
Can I drill my5/16 to 3/8 ? I need to temporarily install and no store around. Thank you for this video. Well explained in an efficient manner! :-0)
Yes, no problem! Just make sure to deburr it
@@dextermonroe95 Thank You!
@@dextermonroe95 they are 6 and 4 g wires, it sure makes what’s left of thee lug rather thim tough, I hope it’s ok.
I was told you can connect two batteries in parallel. I still trying to figure it out. Any advice would be appreciated. Thanks
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)
Where in that would i connect a BMS?
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.
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!
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.
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.
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.
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.
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.
Does the Victron website have advanced battery settings from different manufacturers?
Not really, they give some general guidelines, but the battery manufacturer should be able to give you most, if not all, of the values.
One hint: When working on battery + terminal of a vehicle you better have the battery - connection disconnected. With this you avoid a short cut if you accidentally touch metal parts of the vehicle with your tool ;)
