- Today, I find some time to show you my experience with the ZKE Tech EBC-A20 Capacity Tester and charger. At first glance, it seems like one of the many devices you can buy to test all kind of batteries. BUT this tester can do sooooo much more! When connecting to a computer, it shows its full potential and you cannot only set all parameter for your test within the software but it also draws beautiful graphs of your battery test. This makes the learning experience so much more fun and helps us understanding the LiFePO4 chemistry a lot better.
Leave some comments about what kind of test we should run with this tester, software and the battery.

Fun content again! Can't wait to see the results is fancy graphs soon!
Andy, You never fail to provide me with a belly laugh. Thank you for your most clever work!
My pleasure! 😊
I just love the guy. And he makes his videos in shorts
Crazy, i nearly cried at the unboxing event in the beginning..🤣. Ehm - just ordered the A20H, thanks for your reviews, this is so helpfull Andy!!
Merci très intéressant comme appareil de charge et de mesure... effectivement la partie graphique informatique est très bien, à bientôt !!!
Thanks for the video! I'm going to probably get this model too. The price is awesome for it's capabilities and software
Your videos are always interesting and entertaining...this one was hilarious! :)
Looks like a great device for checking performance of cells for a DIY builder of a battery. Nice that it records into computer and you and refer back to it 6 months later to compare original cell behavior to now. Very cool!👍
Yes, I didn't even think about that. You can record a history of your battery and measure degradation over time.
@@OffGridGarageAustralia I wonder if you could query VRM to plot degradation over time on a graph. The shunt might be able to work that out if you have a regular discharge and have it automatically logging. Could be a cool project.
Can someone help me perhaps with my question? I wonder if it has memory built in? I want to cycle test a battery for 100 times. This will take around 3 months. Do you need to always connect to computer to save data or can I later plug in and take the data of it?
@@pingsangi5418 probably should post your request as a separate comment to original video to get more attention…
Great video! I've just ordered one of these testers .... I've got a pile of 200ah cells coming for my offgrid house. Thanks for sharing!
No problem, glad it was useful for you. The tester is great. I'm using it a lot for all sort of batteries and cells.
have had the baby brother (EBC A10) for 5 years .. very happy with its performance… have cycled many 100Ah batteries at 10A discharge constant current.. all working as expected
Thanks for sharing, Greg and good to hear. The built quality looks good on these devices.
Isn’t that it’s big brother?
@@justbreakingballs the EBC-A10 is a capacity tester. Only the EBC-A20 and three big EBC-A40L can also charge
Merci Beaucoup. C'est très instructif, j'apprends et c'est bien ainsi. bien à vous
Great explanation on setting it up, thanks
Scheint die haben den Tester den ich vor 2 oder 3 Jahren im Plastikgehäuse gekauft habe jetzt mit mehr Power in einem schicken stabilen Metallgehäuse. Die Funktionen, Menüs, Software und sogar der blaue USB-Stecke sind noch gleich. Die Software ist für mich Gold wert, weil damit nicht immer gleich alle Messergebnisse futsch sind, wenn man nach einer stundenlangen Messung versehentlich den falschen Knopf drückt. Außerdem spart sie einem jedes mal nach einer längen Pause wieder neu auszuprobieren wie man mit den Tastern durch die Menüs kommt um die Messung darüber einzustellen. Eine Entladekurve als Grafik zu haben ist natürlich auch praktisch.
Ja, die Software is das Beste and diesen Geraeten. Ich war echt ueberrascht, das das alles so gut funktioniert.
I have a Professional BK Electronics 600W electronic load being an electronics engineer. It has loads of load functions and various for batteries with software for graphs etc. BUT. what it doesn't have is a charging and graphing function. That little tester being able to do charging and discharging and graph it all plus other function for that price it brilliant. I payed over £1K for my pro unit. I will be looking at one of those as I'm now looking into solar. Great videos, keep them coming.
Constant power is similar to many electronic loads that use a DC:DC or a DC:AC converter. The output of the converter will be regulated so the load doesn't respond to battery voltage implicitly as would something like a simple heater (aka incandescent light bulb).
You are going to soon become a tech man . Keep up the great work Andy and you should succeed .
Thank you. I've got a lot of stuff in my garage why I haven't shown you yet ;)
Yup I bought one and powered up + your s/w dls. All installed no sweat. Up and running aws. Great little kit with great time saving graphs - its what you need. However, as you said - word of caution - I will attached an over volt alarm relay set at 4.v for minimal attention operation, Ill still be in the room, just not watching much..
Any comments? Safety first, always have two independent levels of protection for critical values.
Fantastic vid!!! Would have took me forever to figure all that out
Very good description my friend
Glad you pointed out the important difference between those testers. While your videos are a bit lenghty, there's a lot of useful information. Good channel, subscribing now.
I now have my RasPee sending my data up To Victron so I can track everything! Ready for the video with the new BMS, and the Solar Panel Tester, and more fun videos! Thanks Andy!!
Hey, great outcome! Isn't that so cool that you can now monitor your battery from anywhere?
I've been toying with the idea of building my own battery tester, and am impressed with the capability that ZKE Tech has packed into these very affordable devices. Thanks for the review.
it looks cool need one!
You don't watch enough TH-cam videos, I ordered this charger at the same time as my first LIFEPO4 cells.
*I'mgoneagain*
;)
(But it's wonderful to watch. Keep it up.) :)
Great video - more toys to buy!
It never stops. These testers area actually really good and useful. I love them.
Hi Andy. Love tuning in for the humour and the tech advise. I recently purchased a ZKE Tech EBC-A20 tester, but the USB to TTL to Serial / mini USB cable seems to be damaged, or so i believe. I downloaded your files, including the driver for the converter, but no love. After downloading the files, I ran the driver program, then tried to connect. I tried this on two separate computers but still unable to connect. I have tried searching but cannot find this converter anywhere. If you have a source of supply, I would much appreciate that contact. Thanks again for everything you do for us. Go team S.P.A.T.!
Hi, this is really nice battery tester. I bought slightly a different version EBC-A10H, it has 10A 150W max discharge. Br, Eeli
Andy, could you please tell us what the "sunny day" open circuit voltage is for the problem system, at the breakers before the charge controller, with the charge controller isolated.
Expecting around 135.6v for the Suntech 190w panels.
With the charge controller isolated and no current flow any less and there is a leakage problem on the panels. If we have the voltage then the controller is suspect.
We keep seeing voltages at the charge controller of around 78.78v which is 58% of Voc. Clearly not good.
I also note that when you were looking at the history the two controllers showed differing battery voltages. Not much but I thought they would both be linked to the shunt.
Thanks
Thank you for this video. I purchased the EBC-A20 because of this and very excited. I am still learning and hope you can help. What would the computer settings be to fully charge a 8S2P lithium pouch cell be. 24v 25AH each? Any advice sincerely appreciated as I can't seem to Google any advice.
I would like to see how temperature affects the charge and discharge of a lithium battery. Here in Montana I was camping in -15°F weather. Inside my camper it was about 55°F so perhaps you could do some testing in the cooler temperature range.
Great minds think alike. I have the EBC-A40L as well, 40 amp charge and discharge in one unit, it works well for me. I managed to find it under $200 (US dollars) including shipping. I had to wait nearly 3 months for delivery, and now the vendor has increased both the price and the shipping cost. If you have a lot of cells to test, it is just the thing you need. I already had an ET5410 and a 40 amp power supply, but the power supply is not programmable.
Thank you John. I got mine just 2 days ago. It took almost 8 weeks and I paid ~AU$300 incl shipping. It's a fantastic device. I love it. Since it arrived, it has been running 24/7 😊
@@OffGridGarageAustralia I am going to have to email them for the manual. The link on their website leads to a Chinese website with prompts Google translate doesn't work with. I found a 2017 version online, but the link they have is a 2020 version. I will post the software and (if I get it) user manual in the resources section of the forum. So far it has been pretty bullet proof. Old manual says 35 amp charging current max, but mine came set to 40 amps and that's what I've been using. Internally it has a 5 volt, 60 amp supply.
Nice battery tester Andy, can you share the logformat of the software and interval it shows the functions of the device? Have fun!
Thanks Andy
No worries
I have the ZKETECH EBD-A20H. It is only does discharge of the above.
Yes, ZKE-Tech has a bunch of battery capacity testers which don't have the charging capability. They only discharge.
Hi, did you notice that there doesn't seem to be a printer, print function for the Tester/Charger in the Software? The version that I am using comes from your Dropbox link, thanks for that.
Please let me know if there is a way of printing the Graph & data? (other than the Print Screen button on the Keyboard)
Cheers Arthur.
Morning Andy, hope it stays good for you. 20 A not bad at 0 to 30 Volts. Just did a vlog on the other load tester. I mod it, which Vortecks told me would be better. Looks like Brett's DIY tester modified.
Nice 👍
Watching from Jamaica
Thanks for watching from Jamaica!
Dear Andy,
I think the ZKE-Tester are the most underrated device for battery testing. I bought 3 years ago the small brother (ZKE-USB-Tester) where I can test smaler devices as USB-Power Banks, Netadapters and small DIY-Batteries. It has cost about 25$ ... but with this I got a small and cheap electric laboraty: Check on a mWh exact load and discharge. Abolutley amazing what you can do with it!
I saw these USB testers as well and will get one too. They look robust and well build, right?
@@OffGridGarageAustralia It's a small Item - abt 5 X 8 cm only... 2 USB in/out and one to connect with the Computer.
Great looking device and will probably order one. Must be said though that even though it can measure 12v battery’s, the notes say it supports a maximum of 85w so the most it would be able to discharge at is a bit over 7 amps. That’s about 40 hours for a 280Ah battery I think?
Yeah, that is correct. The good thing is you cannot break it and it self adjusts to the maximum power.
@@OffGridGarageAustralia Great video and tester. Bought one because of this video. It also says this "For batteries with a voltage higher than 10V, the maximum charging current should be lower than power current-0.5A." does that mean it can only charge at just over 4 amps for 12V systems (as the AC adapter is rated to 4.74A)?
When you click on the save data option in the menu in the EB software, what does the graphs data get saved as ? does it get saved as an excel file with time series data ?
Большое спасибо за видео!
It's funny, a new subscriber. Thanks for the video
I have a quick question, can we also use the device that measures the internal resistance with this device? My goal is to cycle charging and discharging the cell and at the same time measure the internal resistance.
Thank you
I bought the version of that amazing tester without the charging and used it to test all 16 of the 280Ah batteries I received. Its been
amazing, though I did replace the fan with a quieter one. Its been very useful in getting some of my money back with
the 280Ah batteries, 12 out of the 16, testing at around 250Ah. The first 4 tested around 270Ah.
Oh, right. Well, that's not good if you have a lot of these cells in your delivery. Where did you buy yours?
@@OffGridGarageAustralia I first saw the 280Ah batteries on Will Prowses channel as he tested them very close to 280Ah and so I used his link to AliExpress to order 4, which I tested between 271 & 276 Ah, so I ordered 12 more, and those are the ones that only tested around 250Ah...definitely should have waited and ordered them from your source but I got a good chunk of my money back on the 12 so it isn't too bad and the batteries are fine otherwise.
Hi Andy, as I used the ZKE I found out that you shall not move the clamps while charging...I saw a change of current around 0.3 mA...due to different conductivity....very interesting in the software is that you can setup a bunch of cycles charging/ discharge...very good tool...having seen the battery voltage doesn't tell much about SOC ...wouldn't it be nice to have a BMS monitoring each cell like the ZKE can do...
Thanks Frank. I noticed the same. It draws a dent in the curve if you wiggle the clamp. Better to leave it alone during testing.
Yes, I tested the batch task programming and it's really good. Will show in one of the next videos.
Can you help me perhaps with my question? I wonder if it has memory built in? I want to cycle test a battery for 100 times. This will take around 3 months. Do you need to always connect to computer to save data or can I later plug in and take the data of it?
That's kinda cool! My hobby charger will only discharge at 1.5a max, but that is never seen, usually 800ma from a 4s lifepo4 battery, and somehow it shows over 10 ah from a used 8ah battery, from 3.5v to. 2.9v discharge, I don't know if it's wrong, or the cells can do that at such a low current discharge, they are rated at a constant 200a discharge, I have tested it many times, still the same, I think I saw 12ah or so, when the seller tested them at 7ah approximately, at a higher c-Rate I can calibrate the charger, nuts a isdt 8 cell charger, up to 20amps, it's my 3rd isdt, the first t8 blew up and took the power supply chain with it, the 2nd one nearly a cought fire, wasn't even being used, and melted the case, this one is doing ok, except for the strangeness!
How to use the "Monitor" button named "Monitor" function? I mean how to connect external charger to battery and monitor this setup with EBC-A10H to draw voltage / current graphs?
Thanks for this amazing video! I just got one small question. Does the tester has memory built in? I want to cycle test a battery for 100 times. This will take around 3 months. Do you need to always connect to computer to save data or can I later plug in and take the data of it?
To do such a cycle test, you need to have it connected to the computer unfortunately. The tester itself has no memory, however, you can program it without computer and it will do 100 cycles showing you all the results on the display afterwards. But this information cannot be transferred to a computer afterwards.
Did you calibrate the voltage and/or the amperage? Mines off about .15v when checked with my Sperry DM-6450.
Also ... how accurate is the resistance test that you can do with the tester? Just wondering how it compares with the Internal Resistance tester you have.
Great video as always just wondering why not an icharger. There is a 30a and 40a 6s version. it may not do all of the same things but it can carge from or discharge to another battery amongst other things.
The icharger needs it's own power supply (10-32V with appropriate amps), is more expensive and... don't know anything else.
Edit: it has only 30W discharge power
@@OffGridGarageAustralia oh I just use a bigger battery bank or an old server power supply in the middle of building a solar powered charging and testing station. But your reason makes sense.
Great video! The bad part is that now I have to buy more toy.
BTW, what OS does it support? I did not the chance to download the manual yet.
I wonder what the internal resistance test would show if you hooked it up to the panels both in the sun and in the dark . And ..... lol nice tester , thanks for showing it us .
You cannot test a solar panel with this tester.
I love your videos & so so so funny
Andy, next time you use this can you please test the accuracy of the voltage sensor? I have only tested mine on Lead Acid, but mine is out by 0.1v. So when charging CV at 14.7v I have to set the EBC-A20 to 14.8v to see 14.7v at the terminals. According to the manual it should have an accuracy of 0.01v.
Did you measure the voltage drop across your cables?
Wish they made a version with 60 amp discharge at 24v, somewhere around 1500 watts discharge because the software is really neat.
Haha. Loved the Darth Vader music
The Imperial March was appropriate for the battery to march in, right? 😂
@@OffGridGarageAustralia lol yeah 😂
I'm looking for a battery capacity tester with charge/discharge curve output to computer that can test lithium ion, nicd and nimh batteries, not just Lithium Ion. Do you know of anything that can do all of these? I'm looking, in particular, for one to test 12 to 20 volt batteries for cordless DeWalt power tools. I inherited a ton of NiMh and Lithium Ion batteries that I need to test to weed out the bad ones. Any ideas? Thanks a million. I really like your videos. You have a great way of experimenting and showing how to do things!
Thanks a lot. Well, the ZKE-Tech EBC A20 can do that except it can charge batteries up to 18V only. But it can be set to to any battery/cell you have.
Hey Andy,
I just received the tester that I bought and it came, according to the power supply 220VAC. Is there a way to convert this to 120VAC because in the use we use 120VAC. Would you kindly advise me on this?
Hi, thanks for the info, RE software, I read somewhere that megacellmonitor software works with this tester, have you compared it, have you tested the EBD A20H.would that be better option if only wanting to test capacity and condition of my 3 year old 200ah lithium caravan battery.thanks
Never heard of this other software. The Battery Tester Software works well and collects all the data and info needed.
The EBD-A20H is only a capacity tester, not a charger, and has the same price as the EBC-A20, which can also charge. So don't see the point of buying just the discharger when I can have the charger as well, even it is only 5A.
Thanks for your email btw, which I saw briefly if you're are the same guy...
Your welcome
Hi Andy, thanks for finding a value for money tester, great software. Will P. uses a CBA4 which can also test solar panels, how does that compare though more expensive?.
Thanks David. The CBA4 is limited to 100W continuously only but can handle up to 40A (depending max power).
Price seems 2x - 3x as much as the ZKE Tech. It seems to be more precise though.
@@OffGridGarageAustralia It had better be more precise... I had to pay about $50 extra for the PRO (more precise) version! But anyway, the main reason I posted about it on your previous video was because I thought it would help you diagnose the weird problems you've been having with your panels.
@@OffGridGarageAustralia Yes its is much more expensive, Will P also has the CBA A2 500W Amplifier.
Those voltage lags at specific amp draws are interesting. Wonder if the drop is relatively consistent over the majority of the voltage range.
We'll find out shortly 😉
I managed to get it working by running the download through the PC. When the battery was completely discharged (LiPo -12V) I recharged the battery through its factory charger. When connecting it to the EBC-A20 again, the battery shows a short circuit (it has a display that goes off and has to be reset) Do you know what could be happening?
Nice
Here is a test. Hook up tester between 12v battery and solar panel. Sweep current from 1 to 5 amps. See voltage drop of panel. Basically, a cheap mppt tester.
I don't think we can do this. The tester has it's own power supply and cannot be series connected to another power source (solar panel).
Andy! Where do you get your sound effects from that you use in the videos? They are great!
All from TH-cam Music and Sound Effects for creators.
Hello Off-Grid. Any ideas where can I find that same blue USB converter to buy? I suspect mine which came from the device is faulty.
Sometimes the program doesn’t measure the battery while in the middle of discharging mode for example. I just hope its just that converter
I think this is just an RS232 to USB converter, so any you can buy should work.
@@OffGridGarageAustralia Thank you my friend. I bought the converter and it fixed my problem. Now I can finally sleep without having to constantly check it. I used to think the device was the problem.
@@jasonvoorhees3282 Great, thanks a lot for your feedback!
Andy- Where did you see the 340 amp hour LIFEPO4 cells? You mentioned it in this video I need them! Please support the source. Thanks!
Hi Andy, I was also looking to buy this tester, but the problem was the listing said it can handle only 85W max Charge/Discharge. So we can't discharge a 12V battery at 20A and if I want to test a 12/24V battery it will take a lot of time and the load is too less. Can you please test it for us, if it's true? I dunno why they couldn't make it 180W like the other cheap ones!
Yes, the tester has a power limit of 85W or so. Depending on the capacity of the battery, the test could run for a long time. They have other testers (without charging) which can handle higher power.
I'll test the little one and see where the limits are.
What ever happened to the solar panel issue???
You're asking an awkward question.
@@yodab.at1746 waiting for the tester from China
@@yodab.at1746 it is like it never happened!
Will come in the next video again. We need to mix things up a bit...
There is a whole playlist just for the panel issues. th-cam.com/play/PLPomydD54sgDz7XzMeAKHTfoEw4Zkl3IX.html
@@OffGridGarageAustralia Have you actually solved the problem in videos that are still to be released , or are you still investigating ?
icharger x6 or x8 is nice too for regenerative discharge at 800w
Yes, they are nice devices too, just a lot more expensive...
I like the regen discharge though.
Andy please teach us how to charge lithium batteries with standard chargers. I want to upgrade my lead acid car fridge batteries to lithium drop ins but hoping to stick with my old chargers(dc-dc, solar charger and 240v-12v charger) until I can afford good quality lithium chargers. Tia
The + - aviation connectors are they GX20 3 pin or GX16 3 pin?
Folks, I mean no disrespect. Andy is a excellent educator with a great open, friendly attitude. My only beef is with EVERY solar video I see. Solar is not green, dependable or affordable. The equipment you CAN afford is CE certified ( ridiculous ) and made in China. Wonder why people have solar sheds ? Equipment made in China is unsafe. So, for any newbie ONLY power the shed, I advise you place anything of value somewhere else. Don’t expect the power you produce will be anywhere near as cheep as mains ! The energy it took to create and the effort to dispose the poisonous chemicals in panels, inverters and batteries will null any “green” credit. In one year I have had a controller and 24 volt inverter fail. Garbage ! It is a far more balanced deal to buy a generator that runs on propane. I consider a solar system with ANY battery a bad deal. Grid tie inverters are better but could cause major issues with the power companies. Just want people to know some fax before investing. I have 20 years of experience with DC circuits. Communications Technician an a Network Engineer.
*"...CE..."* Is a play on words to mislead people, it doesn't mean it's certified but rathe it's a *China Export*
Can you do a comparison of the EBC-A20 with the EBD-A20H? what is the difference
One can charge, the other one can't.
Andy what if you connect your 48v battery pack to it. Can you do charge and discharge testing without it blowing up? I know it’s only rated for max 30v but it would be a nice experiment.
As you said, it's rated to 30V, so why would I connect it to a 50V battery?
i have just get the EBC-A20, but i cant connect the device to the computer. I try to install : PL2303_DriverInstaller(USB to TTL converter).exe , this left the drivers in a specific folder, then i connect the usb and appears a new item ,( serial usb) in the devices management- port com lpt.

Good morning friend, how do I install this software? I turned on the device and it only shows com3 in the device manager. Can someone help me ? Thanks
THANKS GERMAN OFF GRID GARAGE MAN DOWN UNDER! THIS VIDEO WAS VERY HELPFUL :D ALSO: ALWAYS PLACE LIFEPO4 CELLS (EVEN THOSE "HIGH QUALITY" EVE CELLS) INTO STEEL BOX AND TEST THEIR CAPACITY AND HOW MUCH THEY WILL SWELL (OR BLOW) UP OR NOT :D
Very andy device Andy 😜
Be careful with 20 A on these alligator clamps... Will they turn red? 🤔
Thank you for your instructional videos, they are capable of always teaching something to the beginners and experts... Keep up the good work.
Thank you Carlos.
The clamps are not even get warm. They are good quality with a strong spring.
20A on discharge means --> max 85w .... so 12v battery can discharge with max +- 7A ( 85watt - 85:12=7 amp ) ...
so - if you discharge 6volt motorcycle battery then max discharge will be about 14amp
Coming back to this thread 10 months plus after it was posted originally. My only regret with this tester is that it only can charge up to 18V. I would LOVE to use this to test my 24V system to test to complete capacity, but alas, I would have to tear the battery apart to do this.
Thank you. The device can test batteries up to 28V but can only charge batteries up to 18V (due to the 19V power supply). You should be able to measure the capacity of your 24V battery with it. Have a look at the specs: off-grid-garage.com/measurement-tools-and-analisers/
@@OffGridGarageAustralia thanks, Andy! Wish it would be capable to test round trip (discharge and charge cycle) for the whole battery like it did for your individual cells. That being said, testing individual Nissan Leaf cells pre-build for capacity proving prior to assembly is worthwhile.
Thanks for taking the time to reply! Early subscriber here who has been following along diligently!
those look amazing, why do TH-camrs always recommend the dl24 when that isn't much more. Added to the wish list. Now if that big version could do like 1000 tests in a row automatically, now that would be the ultimate tester, could test degradation over charge cycles.
Even the small tester can do that. You can set batch tasks in the software which run forever in a loop.
I bought this device for almost a month now. I haven't faced any problem with the actual device, it works great. However, the software is glitchy most of the time, it freezes after some time. I use this device to measure the capacity of different AA alkaline batteries, and it gets really frustrating when the software freezes in the middle of the discharge test. Is the problem coming from the device or software? if so, are there any solutions for this problem?
Can someone help me perhaps with my question? I wonder if it has memory built in? I want to cycle test a battery for 100 times. This will take around 3 months. Do you need to always connect to computer to save data or can I later plug in and take the data of it?
Sorry to disappoint you but you need to ALWAYS connect it to PC in order to save data. I haven’t done cycle test on any battery yet, but I used discharging constant-current and charging constant voltage modes. The computer refuses to connect to the tester while its running, so you have to connect it at the very beginning. If you plan to use it for 3 months continuous, maybe disconnect the display from PC to reduce power.
Glad to be helping you. I can do a test if you want me to.
Do you have the same device? If so, have you experienced the same thing I did?
Without knowing the rating of the load used by the manufacturer used in their capacity rating you can't make comparisons with your own measurements. If you doubt this try this simple experiment. Buy a pack of 4 AA batteries and discharge one at 2amps, one at 1amps, one at 500ma and the other at 100ma and you will up end up with different capacity measurements. Or more simply put, a battery's capacity is dependent on the load it's driving.
I Have this tool But use it with the computer software. How know what should put on test val and cutoff volt in software?
I want check ah on a Electric scooter battery that is a 36V battery and should Have a capacity on 15AH.
How to calculate what test val and cutoff volt?:)
You can't use this tester for a 35V battery. It only allows up to 30V, I think. You can test single cells of the battery though but settings depend on the type of batteries you have, Li-ion or LiFePO4/LFP.
@@OffGridGarageAustralia I did buy the bigger one. Manual say it works for 12-72V.EBC-A40L
@@jonas2149 I have the EBC-A40L as well and it can only test single cells up to 5V but charges and discharges with 40A.

@@OffGridGarageAustralia Sorry it was wrong name! Tool We Have is named EBC-B20H - 12-72V. Have you some Whatsapp or e-Mail to provide only with settings support for us? We are newbie. We appreciate u answer very much! 🙏
Moin, in the manuals it says that max. charge voltage is 18V - so you better of not trying to charge a 24V battery...beside this little "mistake" - good video, well explained that little gadget, just got it delivered today, which Chinese plugs - you forgot to mention, or do you have Chinese wall outlets? I will straight download that software! Munter bleiben ;)
The manual says, you can charge batteries up to 18V and discharge batteries up to 30V. Unfortunately, they are only using a laptop charger as power supply for the tester so charge voltage cannot exceed the 18V.
Not sure about the plug, but it came with an Australian power cable. Easy to replace, right? 😉 Prost!
Good day. Thank you for all your Video's it is very inspiring.I would like to get this ZKE Tech EBC-A20 charger for me.
Can I charge , discharge and annualize a 100ah 12v Lead Carbon, Gel, AMG and a Deep Cycle lead acid battery with this charger?. Regards Neels
Hi Neels, the EBC-A20 can be programmed and adjusted to any battery from 1V to 18V. It can discharge batteries from 30V though. Please find all details here: off-grid-garage.com/measurement-tools-and-analisers/
Endlich :-)
Hahaha, ich hab noch 634 videos auf 'Lager', just need to find all the time...
Hi sir.can i know the link of the software of ebc a20l..tnx
👍👍👍👍👍👍👍👍👍👍👍👍 SUPER.
Does the EBC A20 measure the internal resistance of a cell?
No, it does not. You need an special tester for that. They are not expensive. I have one linked on my website: off-grid-garage.com/measurement-tools-and-analisers/
Hallo
Ich habe Probleme das die volt nicht stimmen . Das kalibrieren geht auch nicht . Bitte um Hilfe. Lg
Ha ha ha oh my word Andy you are just to much from South Africa
Does anyone knows how to plot several battery curves in one diagram? I am building a 24V bank for a saildrive and i want to have one plot with all cells in one diagram.
They make 1000ah lifepo4 cells, I'd like to have about 4 dozen of those! I'd even go to 48v. I'm at 24v now, and seriously thinking about going to 48v, because of the charge controller issues, (requiring so many to charge a 1200ah battery bank, with nearly 5kw of pv....
Go 96V! Thinner cables, less controllers. Are there any SCC for 96V at all? 🤔
I like
Can this unit do cycle testing? Say log and process automatically 500 cycles?
Yes, it can. No problem. It all is captured in the graph and als a csv file.
Do you need to always be connected to computer?
@@pingsangi5418 no, you can program the tester and it will run without computer.
@@OffGridGarageAustralia so it can do cycle testing without computer and after 500 cycles you can plug the tester into your computer and take all the data of it?
@@pingsangi5418 No, it shows you the results just on the screen of the tester. It won't log any data for later processing. For this you need the computer to be plugged in all the time. Then you will get ALL the data and graphs.
Can you run the EB tester software on Raspberry Pi?
Uhm, not sure. What OS would run on that Pi? I have only see the Windows app for the tester so far...
@@OffGridGarageAustralia linux basically. Ie. Not windows
Can the EBC-A20 measure 280ah battery?Thanks
Please run a test on how to get newly purchased battery AH..how to determine the AH if it is under or over or exact battery AH. thanks
Mich würde interessieren ob ein desulfator wirklich die Kapazität erhöht? :) und wenn ja für wieviele Zyklen das wohl hält...
Super Gerät :)
Das braucht man nur bei lead acid Batterien. Fuer Lithium Zellen ist das voellig unnuetz und kann sogar die Batterie schaedigen.
@@OffGridGarageAustralia das ist mir schon klar!
Aber du hast gefragt was uns interessieren würde :) und eine kleine Gel Batterie hast du ja :P
@@MaddinGerk Ach so, hab ich mal wieder verpeilt, das das die Antwort zu meiner Frage im Video war 🤦♂️
But why, oh why, no internal resistance data? Looks like a sweet device in all other aspects 🙃
Yes, it has internal resistor testing as well. And more. I'll show all the functions in future videos, didn't want to overload the video with these software features.
Won’t the iron screw cause a voltage drop on the test?
Everything causes a voltage drop. I can polish the terminals so we have less?
is there a software for raspberry? best web frontend?
