- Опубликовано: 21 июл 2024
- ⚡The Victron SmartShunt is a great way to monitor your battery's performance! It can track things like current, voltage, and temperature, and it will even send you alerts if there is a problem. In this video, we will teach you how to wire and connect a Victron 500A SmartShunt to an SOK Battery. This is compatible with all versions of Victron SmartShunts, and also works perfectly for all SOK batteries, including the 100Ah and 206Ah versions.
🔋SETTINGS:
Battery Capacity: Varies depending on system.
Charged Voltage: 13.8 (*2 for 24V & *4 for 48V Systems)
Discharge Floor: 10%
Tail Current: 2.00%
Charged Detection Time: 3m
Peukert Exponent: 1.05
Charge Efficiency Factor: 98%
Current Threshold: 0.10A
Time-to-go averaging Period: 3m
Battery Starts Synchronized: Disabled (NOTE: you will need to fully charge your battery to sync up SOC%)
State of Charge: 30% (NOTE: Set this to 30% with brand new, untouched batteries. They ship at 30% SOC%.)
💡Comment on Discharge Floor:
Setting this at 10% is going to set the SmartShunt to indicate 0% remaining and 0 minutes until empty when the battery is actually at 10% charge remaining. This is best for optimal life. If you choose to fully discharge your battery (not recommended) then set this to 0%. If you want to be more conservative (not necessary, these batteries are VERY robust) then set this to 20%. Keep in mind this will NOT limit discharging, just what is visually seen.

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!
Thank you. Victron’s guide was a waste of time but I got through everything using your video.
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!!!👍👍
Your video is amazing!! Very good quality. Lot of information. Thank you so mutch !
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
:) Thank you for the kind comment, I do believe you are correct, although I'm not looking at your order right now to confirm, it's very likely!
@@davesdiversions8078 I'm glad! We try our hardest to help out.
Thank you for a simple and easy to follow 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!
Easier to avoid marriage, just sayin’ lol

Thanks for the video it was helpful … so I’m assuming all my negative terminals now go to the left hand terminal on the smart shunt
Great video,really helped a lot.Thank you.
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.
Yes, so helpful! I will be hooking mine up tomorrow. Yeah !! Thanks Again!!!
best video on the internet!!!!!
im assuming the process stays same for batts wired in parallel?
Very good explanation and basis to ask the right questions to your battery vendor. Whereas the standard Victron doc is a little bit terse..
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?
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?
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.
Very good video, but those settings are for any bank of lifepo4 batteries?
thanks great tutorial helped me a lot
Great had no clue how to use thanks.
How can you add a second auxiliary battery to the shunt?
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?)
What do I need to change with two Lithium batteries for set up?
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.
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?
Where would the shunt go if you have to SOK lithium batteries next to each other on a fifth wheel?
So how would you set this up for a Lithium ion pack that is a 4s.. so 16.8 fully charged..?
What was the other wire? A temperature probe? Is there a way to measure and set a low temp alarm?
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?
Can you turn the bluetooth off for when the battery is in long term storage? I would think the bluetooth will slowly drain the battery.
Perfect! Thanks dude🫶
Happy to help!
Are your battery settings good for all 100AH LiFePO4 Batteries?
Hi lm setting 2 48 volts lithium battery what is the set up for those Thankyou
Thank you. Great tutorial. What are the parameters for the 206ah battery to program a Victron SmartShunt?
Everything is the same except capacity is 206ah per battery.
is there a video on the victron battery monitor ?
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 SOk 12v 200a battery the same setting other than change from 100a to 200a. What about 24v SOK battery too same?
Do you think using 10 gauge cable to run 40amp is a bad idea? Your guage seems to be 6 or 8
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
i have the same question , what did you do eventually ?
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!
do u have to do anything different when u have 2 batteries connected in series
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 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 a shut have a useful purpose on agm batteries?
What should my charged voltage be if I have a 206ah sok battery
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.
Thank you for this tutorial. What if you have two batteries?
Not knowing what have makes it impossible to to answer.
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?
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.
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?
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?
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
That sounds like a waste of money then. I think the negative side of this accessory it's that you need to fully charge the battery first and set it at 100© in the app so that the smart shunt shows an accurate SOC
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.
Will this handle a little 4volt battery bank? Is there Low Voltage Disconnect?
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.
Thank you !!
My system went back to default. How do I increase the battery capacity from 200 to 600? Thanks
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!
Say I have 3 200ah batteries, does the red connector read the whole bank? Is that adjusted in settings? Please advise!
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 %?
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🤪
Can you make a vídeo connecting 2 lithium batteries! Thanks
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.
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 just installed a 200ah LiFePo4 battery in my small RV. Are all those settings you showed on the Victron Smart shunt applicable to my 200ah battery?
I'd like to know as well
I am in the process of setting up the app for my Victron shunt and I have 2 off 200ah lithium batteries. Do I set the battery capacity at 400ah?
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.
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 have two batteries wired in parallel; do I connect a red wire from the shunt to each of them?
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?
SOLID!
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!
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)
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%.
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.
EXCELLENT MATE....
The newer version has the positive and aux cables hardwired in.
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.
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!
I have 2 100 ah hour batteries. How do you do those?
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.
are these the same settings as the 280Ah SOK ?
Where in that would i connect a BMS?
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.
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
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?
Support team?
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.
Not sure what the point of insulated tools if you touch the battery post anyway?
excellent vid, thanks. I have 2 SOK 12s in series for 24 volt. what would the parameters be for that. FYI I have the all in one MPP 2427 and I have had midpoint voltage deviation issues. I have ordered the balancer from watts247 and I think I need to rewire onto the shunt and not the battery minus as you mention. thanks again. Dan
Hi,did you get your answer on that? How's the 2427 working for you,I'm about to install one, thanks
@@mikejohnson7768 nobody every answered the question. but my system is working great (after I installed the balancer from watts247)..the smart shunt is always telling me about the midpoint deviation, but the balancer does its job and the batteries charge and work great. After I did a major rewiring the shunt stopped connecting but i reconnected it. keep a screen shot of the sku number handy.
@@dans1516
Great,could you send me a pic of how you wired and fused your 2427 into the system with your smart shunt, thx
@@mikejohnson7768 I will make a video and post it in the next few days.
@@dans1516 great,thank you
I believe it's a 13mm instead of 14 mm. It's 13mm for my 206ah.
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
Good video
Glad you enjoyed!
Do these only hook up to 12v. Or can it be hooked to 48v.
Any voltage up to 70v
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!
are you fkn kidding me?
@@mooneyman13 and? Problem solved?
@@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.
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)
Are you sure it resynchronizes to 100% Maybe better to fully charge then set SOC to 100%?
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.
Will this work with 2 lithium batteries in parallel?
It would work with many up to 500 amps of batteries
why did you do 13.8 for this battery?
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
