Holy smokes mate! I bought the exact same item from Amazon and couldn't find any video of wiring. I can't thank you enough. I got kinda confused by the diagram since it's missing the instruction. Thank you tons!!!!!!

Great video. Was wondering which side of the shunt to connect to load. Now I know. Thanks a lot.

Thanks for taking the time to make and share this. Hard to come by much detail on this 'less expensive Asian stuff' :)

Thanks mate I couldn't find a video on this either. Really helpful.

Thanks for doing this. Fitted mine today and went without issue.

Thanks man...looked all over, only vid I could find showing install.

Hi mate. I see you commenting a lot on a lot of channels I follow and I just worked out that you have your own channel. And it’s a beauty too. Love all the tech stuff. Anyways I’ve subbed now and looking forward checking out more of your vids.

I just bought one, Thanks for the video, it will help!

clever idea with mounting the andersons to the under side of the lid, I like it :) I am needing the rewire my battery box so I may just copy what you have done haha

Thanks, worked great for the 100amp shunt/monitor I got for $18 from Spartan Power.

Good instruction, excellent video, now I know how to use it.

Great Video Dino !

Very clear and precise thank you so much.. I was wondering about the fl- 2 and the opposite end 300 amp 75 mv... And it was as you said what I was thinking it should be placed in accordance with connection..again thank you my friend .. I liked And subscribed.. for more updates on such matters 👍

Thanks much, this was very useful.

Hey Dino Neat little video mate. Love the comment “EBay my religion” lol

Btw... Screwing the shunt directly into the battery is brilliant! Can't get any closer.

LOL!!! The Dremel on the plastic box sounded like Chewbacca was in extreme pain!!!! 🤣🤣🤣

Perfect mate! Cheers

Well great video thank you for making it. I really like your mounting job unfortunately I won't be able to do that so I was wondering if I would be able to drill two holes in the shunt and mount it to my wood platform that I'll be mounting the monitor itself too as well?. And I was also wondering about the external power supply would that be coming from the solar charge controller at all or does anything even need to be put in there? Thank you again this was very helpful. This is my first solar build I'm running one 100 watt panel a Renergy 100ah battery. And I have the 100 A-FL battery meter. I hope to add another 100 watt panel in a couple of weeks. P.S. love the shop, you're having fun.

Just for your info, that shunt can be wired from either end, it does not have a polarity sort of thing, but of course the wiring of the sense leads still need to be correct.

Good video Dino. Not bad for an ebay buy.

Helped me bro just wired it all up cheers 👌

Hey mate - I watched another vid. If you swap the wires around (the originals - I think the blue and yellow) It then works in reverse. (you can actually add a switch to swap it around)

thanks for the info

I like the renogy ones

Good vid bro!

Cheers, came in handy

Hi i was wondering, the SOC displayed on the screen should not be accurate since it is not a coulombmeter but just an estimation according to the voltage. But if we have a lifepo4 the voltage varies very little so this type of display can not correctly estimate the SOC I am wrong? You would need a coulomb-meter for that (which counts the real current that has been used). Or am I talking nonsense and the displayed battery soc is indeed based on the outgoing current? What do you think?

handy vid, just bought one myself

Thanks. I just installed one

I have same setup but after installing it to battery box can't run fridge from Anderson plug only from outside screw +/- connector

got the 300a one off amazon, arrived in 3 weeks. did the same thing with the battery box and replaced the crappy battery monitor.

Great video, great product, please allow me to recommend a new KG140F

oof thank goodness for this. I'm a total idiot when it comes to these things and I was bout to wire mine up incorrectly

Great video and as you said no other one on online. I wish to place the monitor inside my caravan which would be about 4 metres from the 200A shunt which I will attach straight onto the battery as per your video. So I would need to have each of the four thin wires extended by about 4 meters to travel that distance. Now my question is, will that distance of itself adversely effect the readout and would I need thicker wires (presuming I could extend in the first place)? Thank you.

Very useful video. I just purchased one for my sailing boat battery. You added a fuse. Please, what size fuse did you install? Thanks IK

I'm going to get two, one for the inverter and one for the solar panels. It would be nice to see both at the same time

Great video I can't see the charging power on my one though when I got it on 12v charger wrong setting maybe 🤔

It makes no difference which way the shunts are connected; nevertheless, the leads that go to the shunt, the ones that connect to the small Phillips heads, must be properly fitted, one on the battery side and one on the load side with the correct corresponding port. I have used many of this meter, they are reasonably priced, and perform well.

Thanks for the video!!! Will this tell you how many amp hours are left in the batteries at any given time by AH?

Hey Matey. Do these measure forward and reverse current. i.e. show charge going in with a "+" and charge going out with a "-" ?

Thanks for the video, I have one of these monitors . I have an Enerdrive dc2dc charger and have noticed that the amps shown on the charger don’t match with what it says on the monitor , I don’t have anything running at that time either, if I had the shunt back to front would this effect that? I haven’t looked at the shunt as it’s behind my wall in my canopy. Cheers

Bought one of these thinking perfect for my use . Load of bollocks been through three of them and they still don't do as they say. I gave up on them.

Thankyou

Good vid have you done a vid on how to program monitor mine keeps half full when battery is full thanks again

Nice video i installed the multi meter bud dont understand where the load cable from the chunk gets conected to ??? i have all cables ready bud where goos the load mmmm on to the negative from the battery and the other one where do i conect it . thanx and hope for your responds . thanx buddy

Hi I’m a truck driver and I am thinking of taking a 12v LED TV & PS4 to play for 2hrs per night! both low wattage. Really confused as to what set I need!

Hello mate. Wanted to ask your opinion on a few things. -Do you think it will affect readings if I had my monitor on extended wires three or 4 feet away from the battery shunt? -do you think it will affect readings if I have the load side of the shunt connected to a vehicles chassis and all loads connected to the vehicles chassis at at a different location. -I have a two battery bank set up in parallel. I have two monitors and was looking to monitor the batteries individually. Although they are working as a collective. Yours or anyone else's thought would be awesome

Hey Mate, Can you think of a reason why I'm not getting a Voltage Reading on my meter. I rewired the shunt (200amp) because I thought I might have got it wrong there. Then checked all the connections and they match yours, My smart charger is charging at 13.4v so it means the battery is near full. Using a 375mwh Inverter and a 12v 110ah Deep cycle battery. Still missing something as the Voltage is not showing. Also, internal resistance is 0. Anything else to correct?

Shouldn’t the shunt go on the negative terminal of the battery for safe , accurate measurements ?

Hey mate does when you have charge going in and also using the inverter. Does it add the charge and use together? Like 5ah in and 5ah load show as 10ah?

Hi there, do you think it matters of the small wires are replaced with longer ones just because of where I plan to mount the meter. Thanks

Hi these are great But i have found when i charge my battery and the charger turns off it kills the screen if i turn off b4 full charge ok Do you think it gets a spike when charger turns itself off? How could if protect from this

Thanks heaps just got 3 for projects - I only bought 100amp shunt. How do you determine the shiny capacity?

Hi mate, do you know if these are ok to use on a lithium battery hard to tell what your 12v battery is, unless I missed it.

At mark 00:55 you talk about what end of the shunt goes to what terminal. I don't see such exact instructions in the manual. Why is this specific layout important?

Being a nuisance, sorry. I notice that in the testing the glue gun said 8 amps but the amp hours was only 1.66? and when you turn the unit off (dormant) do you have to redo all the settings? Thank you.

Does the small wires get overheated or melt at all when drawing high amp?

Does it tell you if the battery is in Charge mode or Discharge Mode ? I tried on my side and I am disappointed. My current is always positive wether I am discharging or charging the battery.... Maybe I did something wrong... But hard to know... Thanks in advance if you can confirm or not on your side. Thanks for finishing your video with confirmation for me. It is a pain this monitor is not doing that... I consider it USELESS then... Then it is useless in terms of current measure... Just useful as simple voltmeter to estimate roughly the battery capacity... But does not tell you the real capacity...

Can I run my wire directly to the shunt to power my appliances?

Fortunately to see your video, JUNTEK has launched the new KG140F. We look forward to your comments.

What you think if put this 300 amp battery monitor on 1000 amp battery bank?

SpeedPAK my arse should be called SloPAK

What size wire is use to extend the meter

Have you tested it to see how accurate the guages actually are?

I have the meter hooked up like you described. I have no idea what the read outs mean. Can you please make a video that explains what the 9 functions the meter monitors? Eg... I have a 100 mah battery. The battery level icon shows full. The numbers at the top right (mah capacity) reads 4.85 and climbing. How does that number relate to mah capacity? I would think that it would determine the max capacity of the battery. This seems to work great based upon your video, but I have no idea what all the numbers indicate. Do you?

Thanks you does mine show me me some info but not ither times?

just fitted this in my car is there any way of seeing how much charge is left in the battery

Thank you, why isnt that center battery icon not working?

What do the diffrent sized/amperage shunts do?

How do u reset one of those battery monitors I have the same one but the reading just keeps going up & up when I disconnect it I'm trying to reset the thing

Does it work on twin batteries and lithium…..thanks

Wiring the shunt makes no difference which way around it's connected.

Where is a link to find this?
