Hi there 😀. I'm not sure, sorry. You can however read about it here: 68.168.132.244/KG-F_EN_manual.pdf

[@junctek7696]

Yes, although I understand a little what you mean, I can explain the remaining time here; when charging, the remaining time represents how long it will take for the battery to be fully charged according to this current; How long does it take for the current discharge to be empty.

[@diydsolar]

Hi I have seen that the shunt is really a 200A one, does the unit limit by software to measure up to 100A ? I have an installation in which some times and for very shorti time I will have more than 100a (about 125-150A). I know that there is a 400A version, but most of the time, at low discharge rates (below 1A) I think that 100A version will be better than 400A. But this is my doubt, does the 100A version measure more than 100A ? Thanks

[@Italjohn]

Hi there. I'm not sure, but think the shunt is the limiter here. It will be very hot if you pull a lot of amps over it's design value (100A)

[@RND-USA]

Hello! Thank you for creating this video! I have a question regarding its usage. Can the kl110f be used with cars or car starter batteries? If yes, do I need a larger shunt due to the spike in current caused by the car starting? I want to monitor parasitic drain current, which is under 1A. However, I'm unsure if I need a larger shunt as my car battery has 500-600 cold crank amps (Honda Element 4.2L, 4 cylinder). I've seen many people using this product in RVs, but I'm not sure if they're using it on their starter battery or on their secondary/leisure battery only. I would appreciate any thoughts you may have on this. Unfortunately, I'm unable to reach the manufacturer.

[@Italjohn]

I have not seen anyone using this for the start battery. I use this one on a daily basis, and can really recomend it: s.click.aliexpress.com/e/_DEryK4V

[@RND-USA]

@@Italjohn Hi, thanks for the reply! I’m hearing from some other KZbinrs that it can be used but that you need to install an additional switch for over/under current protections. I clicked on the link you sent. Is it for the Uni-T UT210E? If so, funny, I just got one from Amazon yesterday!! I'm just hoping to find a reliable Bluetooth solution because the car is a Honda Element camper SUV that I don’t use very often. The Element is a gem in the camper world, but I see it has one known problem: parasitic drain. For some, the drain has one source. For others, it's a more extensive deep dive. Have lost count of the batteries I’ve bought, but I am trying to keep the current one alive with an MPPT 10w solar panel in the meantime. I need to measure charges and drain under 2A currently, so assume if this coulometer is like some others I’ve researched that, it’s best to get the smallest shunt for more accurate readings. Yet, I don't want to fry the thing by cranking the car. Re ut210e: The strange thing is I put it in DC mode and tested it on the load live wire of my solar charger while charging an iPhone. Two USB meters running simultaneously said the current draw was 1.5A, but the Uni-T said the draw was only .600A. Did I get a bad meter? … yet another thing I’m currently researching 😅😅

[@RND-USA]

@@Italjohn I heard back from Junctek on this post asking my question about Car/Starter batteries. They say theres no problem using their shunts with cars, just need to varify which size they still recommend for measuring low Amps with a 600 CCA battery.

[@aaamarco6726]

Che software usare per collegarlo via wifi al PC? Grazie

[@Marty501000]

I have installed several of these but today I needed put the battery further from the display. It works with the supplied data cable but when I used a locally purchased 5 meter RJ11 cable the display does not work. Has anyone successfully used a longer cable and can you advise?

[@mattbarnes3111]

[@tommyfournier3138]

Could I use this to keep track of the power generated from my wind turbine? My display is in the electrical box and no way to view it remotely. 48v 2000w capacity. I would have to use the shunt between the battery and charge controller I assume because before that is 3 phase ac.

[@Italjohn]

I can't tell, sorry.

[@NeoVdV]

I connected all, the screen works OK - BUT the Bluetooth won't work. In Android the tablet can find the device but not connect. In iOS the iPhone can't find the device at all. In Android on my tablet as well in iOS on my iPhone, I already Uninstalled the App and downloaded again but no change at all. I also tried to set a different pass code, on the screen module, to connect the Bluetooth but also that didn't work. I disconnected the main module from the power and reconnect, no change. I did a full reset on the screen module, no change. Still doesn't show up in iOS. Shows up in Android, asking for connection code, but doesn't make the connection :-( 😢 What to try or do next to make this work ??

[@davidmcgregor7161]

Thanks for your time, You showing the firmware reload gave me confidence. I have a issue you maybe able to help with? I need to change android phones it is connected to, but the replacement phone wont connect. I can reload the firmware without issue on the old phone, Firmware 1.3.22. Both phones are Samsung S8s. I see there is a later version of firmware that is not on the play store, and prefer it to be isolated from my phone with a SIM Regards from Australia

[@davidmcgregor7161]

To answer my own question. My problem is resolved. I used a IPAD version 1.1.12 (From the app store)to upgrade to the latest that has low temperature support and now with the other S8 loaded to 1.4.25 it works fine. I do like the low capacity alarm ( instead of using battery voltage). My intention was is to use it to switch opportunity loads, but it only gives a notification on the phone. ( Idea for some applications). Using it to energise the relay would have suited my application better. My 10 cents. Just a note: I used the android S8 with Ver 1.4.25 to reload firmware ( And from the IPAD),. You need to use the "After sale" icon with pass code" 8610" then "000" I am very impressed with this product, top marks to Junctek For Price, function, and continuing development.

[@Italjohn]

@@davidmcgregor7161 Thanks for the update David. Will try to update mine as well. The low temp is a welcome feature as well.

[@Italjohn]

@@davidmcgregor7161 Where did you find the "after sale" icon?

[@davidmcgregor7161]

@@Italjohn After updating software to the latest. In the setting tab, after sale is a new icon that replaces firmware upgrade. I loaded firmware twice to check i could. The process has the extra 4 digit code. You also have low capacity alarm and low temperature protection icons as part of the upgrade. I installed it over the easter weekend, 35metre cat5e cable with new RJ11 connections take the display from the battery room to inside the house, used 2 spare wires for a buzzer inside the house. It works well. The bluetooth range is not far enough so i have not used it. Aways happy to hear from you Cheers from Sunny Queensland. OTG since 2014. David

[@Refertech101]

@@davidmcgregor7161 this is the sort of user case scenarios I look for! I was thinking of fabricating a longer cable if needed and was wondering what the max was or at least what one could get away with!

[@CristianZamora]

I have an updated screen version that doesn't allow for current calibration

[@FloydFamily]

Italjohn, I have the KG-F Series Coulometer paired with a 100AH LIFePO battery. I cannot get the Battery Remaining Capacity (Battery remaining % image on the Display) to report Percent Capacity based on the remining voltage of the battery. I’ve tried fully charging the battery, then setting the Coulometer AH Rmn to the value on the display (Vs. setting the AH to the 100AH value on the front of the battery), but the Coulometer Percent Capacity image doesn’t move or is incorrect based on the current Volage reading on the Coulometer Display. Any idea what I am doing wrong or how to fix this? Doug F.

[@tyrausfarrelly6257]

I believe this would be due to the fact that a LIFePO battery will maintain its voltage almost to completely flat, unlike an AGM battery where voltage drops as the battery capacity drops.

[@arizonaaerialproductions6390]

Do you know of a shorter cable that will work from the main display to the controller box. I need a 3 foot cable.

[@Italjohn]

It's a standard old style telephone cable, so any length will work

[@Italjohn]

It's a battery monitor, which is very handy if you have a leisure battery in your car.

[@Refertech101]

it is a power monitor for battery banks, for me it will be monitoring my 48V house bank that runs my house (as the name implies)

[@northcastfishing]

Does the shunt get hot zi notice it has a heat sink. Would like to use in a marine application but it isn't waterproof. I ask because I would like mount in a waterproof box.

[@Italjohn]

It will get hot if you loads the circuit close to max. So if you "need" 100A over a long period, buy the 500A version. If you only need 40A go for the 100A version.

[@northcastfishing]

[@steveclunn8165]

@@Italjohn one thing I noticed that could be improved upon is that when you are measuring small voltages like one lithium cell the graph with it's 1to 120 voltage scale its hard to see voltage chang of 1 volt . I like the way the meters on the first page can be adjusted to like 2.5 to 5 volts for 1 cell. Hard to see much of a difference when they total swing is 120 volts on the graph same thing with the amperage.

This is probably old but can you tell me how to switch from charging to discharging I have a zantrex freedom in verter It always seems to be discharging I don't get it

[@Italjohn]

You can't switch from either, as this is just reading what way the current is going.

[@Refertech101]

if it is reading as charge, when you are not charging but drawing power, you have installed the shunt in revers, recheck all your wiring and correct errors.

Good day. Can it shut down output based on battery state of charge?

It can shut down on over voltage and over/under current. You set the alarm to what voltage/current you want it to.

There are overvoltage protection and overcurrent protection functions, an external relay, when the protection condition is reached, it will send a signal to the relay to disconnect the circuit
