Thank you for doing the full "How To" vid about this DL24/DL24P electronic load , the manual is soo bad, miniaturized with a bad AI translation . i had figured part of it but gave up ... until your generosity made the total difference , Thank You much ,cheers from Montreal + Subbed 4 sur =D
Very good, comprehensive review. Well done and thanks!
This video is a very good comprehensive detailed use of this product. Many Thanks.
Thank you! I just bought this and this is very helpful, You got a new sub from me!
Perfect review. Thank you.👍
Nice test, but I'm amazed that the tester can sustain a load of over 300W while only being rated for 180. I saw reviews online where people said that the mosfet got killed when they exceeded 180W...multiple times. So either the build quality went down or you got lucky
Very detailed and clear review, Thank you
Thank you for this video, very helpfull. Thank you once again.
I'm going to buy one soon! It will be a huge help testing 180 8AH lithium cells. I definitely have work cut out, thanks for taking the time to review this. It looks awesome 👍
They have models on his Ali link with larger load boards
there are versions up to 600W if you look around.
Just got one for 19 euro's...
ure review will help me in a month or so i took it on ali but without the cooling fan and saved (on fan and shipping to add the DT24 extra)
Very accurate and super helpful 👍🏻👍🏻👍🏻
Thank you very much for sharing!
Beautiful review ,……
What a useful equipment,…..!
I am looking for one,……!
Thanks for this! The included instructions are so incredibly bad! This video told me everything I need to know.
Great work. Thank you!
Most excellent video.
Explained and showed, all the functions clearly.
It is also the up to date device, a lot of the other videos are of an older model of this device.
I'm now off to test my Lifepo4 cells.
Thanks for the upload.
Can you make a video to show how to drain different voltage batteries to determine their capacity? For instance 48v 15.6ah 748.8wh lithium battery pack. How to run the test such as What would be the low voltage cut off be? How do you compare the results to the battery specs to determine how good the battery still is?
I have it on my list.
Thanks for the review. Ordered from Ali. They have a model which includes a battery board with lithium adapters plus I grabbed some single cell battery holders for testing my AA / AAA - want to recycle failed / unmatchable batteries
The best thank you for me is to subscribe to my channel. Your subscription is stamp of rating to my channel and others can find me too. Thanks
Excellent review. Thank you. I wanted to know how easy it was to set the current with the buttons. Looks great.
you are amazing i subbed!
Thanks for subbing!
감사합니다
물론이죠.
Thanks! I just bought one of these and the instructions are pretty poor!
Gracias por todos sus vídeos.
Una consulta. Tengo un DL24P y me gustaría testear las baterías 18650 individualmente.
¿Cuál sería la configuración de descarga ideal (V de corte y mA de descarga) para saber con exactitud la capacidad de la batería?
He hecho varias pruebas y dependiendo la intensidad de descarga que configures te da un resultado diferente.
¿Cuál sería la tensión de corte ideal para una 18650 y que intensidad de descarga sería la mejor para arrojar uno valores finales mas exactos?
Mil gracias.
Hello thanks for such a detailed review. I have a question in 21:56 Demo: Soler Energy monitoring Im not sure what you are doing. Are you charging a battery using a solar panel? Im unclear what is the connector on the right side for...? I think you connected a battery to that connector. But if you are charging a battery then why the 75 mAh is not increasing? I see the amps increase from 5 to 6 etc but I don't see the capacity increasing. Im not sure what is that righ hand side connector for? Thanks very much
Hello. You said that I am gonna demonstrated current reference 13:15. Bu you did not mentioned about it. I have just bought this module but the current value is wrong. I set the current at for example 3A then start. İt says cur:3.00A but the power supply says 1.7A. there is huge mistake. How can we do current calibration?
I am not sure about your powersupply or settings. There must be something wrong. your powersupply may not have enought power.
@@WattHour No actually the case is opposite. Even I try to draw 0.3 A it is wrong in eload screen. My power supply can supply 5A. I put a calibrated ammeter between power supply and eload. The ammeter and the power source say exact same current value but the current value on the load screen is higher.
What if I want to test a board that outputs a 14V square wave of about 9kHz? I assume I need to put a bridge rectifier in between that board and the load, but do you have a thought about sending it a rectified square wave (which will have notches about twice the input frequency from the transition points on the rectifier), or testing a motor controller that will output DC PWM with a duty cycle of 0 to 100%? The PWM would be set to 100Hz or 400Hz.
hello nice video, i should measure the power watts of usb 3.0 and pd power supplies, i'm looking for a cheap one that does just this, which one do you recommend?
There are plenty of USB loads that can do that. There are some integrated ones, but it's usually better to get a separate meter and load.
Bought mine on 11/4/22. Your PC software is a lot different. Thoughts ??
excellent review but what is the name of the thermal camera app you use to see the temperature of the cable?

Nice video. I missed your review of this device connected to an iPhone. As far as I know the E_test App user interface in iPhone is dead. The App is practically useless. The app reviews confirms that. Never saw any review of this device with iPhone. Anyone?
It's bought.
I want buy this for checking ebike batteries. What do you think? It will be good for that? 36V (discharge rate 2 or 2.5A) batteries I want to connect to output of the battery without disassembling.
If it works the way it is claimed, it should be helpful assessment tool for ebike battery packs. I use a similar Constant Current 180W/200V tool for the same purpose. I don't need the other test options (like constant voltage) nor do I require the color display or phone/computer connectivity, so the unit I use was a bit less expensive.
You may want to determine whether or not the DL24P is the "improved" version or some sort of "Premium" version. There are supposedly at least 2 versions out there, the 2nd has been reported to be an improved version, *suggesting* potential limitations or glitches with the first version, and I would want to be certain to obtain the improved version if such exists.
CAUTION:
Before actually using any of these types of units, verify the heatsink mounting system is working properly and isn't loose or even broken.
One bad thing I've noticed about most of the versions of this type of tool I've had the opportunity to examine, is that the heatsink mounting system, a critical part of the unit, was held down on the printed circuit board by 4 simple plastic pins. Even working perfectly, these pins can allow an almost 1mm up and down motion of the heatsink relative to the MOSFET just because of poor design. This motion breaks the thermal compound bond and DRASTICALLY decreases the functionality of the heatsink. This can then cause the MOSFET to burn out at any time, even when testing relatively low-current loads. The MOSFET specification REQUIRES a tight fit to the heatsink even with low watts dissipation requirements.
Some of the securing plastic pins were even broken during during shipping, even to the point where the heatsink was secured by just 1 pin and flopping around on the printed circuit board...completely detached from the MOSFET.
I replaced the pins and secured the heatsinks with non-conductive bolts to assure a secure and snug fit to the MOSFET on a number of these types of analyzers/testers. In some cases, the MOSFET had to be replaced before the heatsink attachment plastic pins were replaced with the bolts.
Thank you for the video!
If I want to discharge a power bank just to, what's the correct cutoff voltage? 3.7v or 4.10?
Because I want to know the actual capacity of my power banks
Thanks again for the video ❤
powerbank has its own internet programction. I assme you have a power bank with USB output which is 5V. so set the voltage to 4.5V and before it reacheds to 4.5V, your power bank will disconnect it .
Thank you for you excellent video. Can this unit charge batteries as well?
I have shown all features. this is just a meter.
Res is battery internal resistance ?
How can you trigger the USB PD to get for example 9V or 20V constant current load to a Power Bank?
if a USB has the PD feature and your device connects, it will automatically turned on. you don't need to do it.
How to communication with wall adapter to increase voltage to 9v or 20v 😢😢 I use to test power pd adapter automatic adjust voltage by adapter
Can you increase wattage power inside settings? I can see it says 185w, and with MOSFET and diode replacement it is possible to upgrade this tester to be more powerful, but still limited with software.
No. There so software or firmware limitations which we can’t access even you change the mosfet or shunt resistor.
@@WattHour not sure how to show you but there is on DL24P settings under V5.1 version of the software
Hi, very informative and promotes confidence on the product. But how to make it measure more than 99999mAh capacity? Like the bigger lifepo4 batteries that go beyond 100Ah? Thak you.
Mine changes from mah to ah after it gets above about 5000mah. Im curently testing a 250ah lfp
Thanks Mike for your reply. I ended up buying the DL24M few days later because even the on-line sellers could not answer my question. The DL24M I found has 6 digits on the ah display.
Sorry it's Mark.
@@erichenares6172 i just realised it was on my phone via BT it shows ah, the display shows mah, im at 80400mah and counting as of right now. Ill see what happends in an hour or so. Running 10 amp at about 13v. Been going for 8h.
Edit. Just passed 99999 mah, and it changed to 00100ah on my 5 digit display.
Thanks for the update Mark. It's good news for that model.
Can you tell if the external temperature sensor can be used as thermal protection?
I have not left any features out and don’t remember. So watch the video fully yo see if I have shown it.
Great video - question; how to you change capacity from mah to ah?
Hi, I don't have it in hand because it is given away. But I explained all features. if I did not show, then it is not possible.
You can't change the mAh to Ah manually, however you can divide by 1000, right?
Once it exceeds 80000 mAh it automatically changes to 80 Ah... Or something like that, just read other comments here.
How to using CV?
Hi....may I ask question about Canada and battery...I thought there's always power supply there
Hi, "Canada and battery." ?
Can I test CR Battery, CR2032 specifically, with this? I want to measure its capacity. I got ton of them for very low cost from ali-express but I can't figure out its exact WHrs.
If the voltage is within the range of this tester for you can.
Thank you for replying, i appreciate it. The max CR2032 can give is 3.3V. I want to pass constant current and measure how long it takes to reach the cut off voltage. So that i can guess lifetime of my battery operated beacon.
@@satvikkumarpatel1129 - this is WAY too big for a CR2032. Just buy a small $5 USB load and a decent USB tester that has an external power supply terminal.
You need the external power because most testers won't work on 3V. Also the tester will draw too much power and skew your results.
To be truthful, since there is so little power in a CR2032, you are probably best to just load it with a resistor and measure using a multimeter.
is it possible to store all the data in a file for a given test? at least the voltage and current vs time would be nice.
No. I would have shown it. I have not skipped any feature of this module.
You can save the data to an XLS file in the PC software. Note it is actually in CSV format so you need to change the file extension from XLS to CSV after you save.
@@WattHourare you able to also review the dl24ew model thanks
merhaba. şunu merak ediyorum; telefon bluetooth ile bağlı değilken cihaz veri kaydediyor mu? yani telefonu bağladıktan sonra önceki veri grafiğini görenilir miyim?
selam, gördüğünüz tüm veriler sadece onları gördüğünüzde mevcuttur. ekranı kapattığınızda kaybolurlar.
bạn cho mình xin link để lấy phần mềm cài trên máy tính được không, cám ơn bạn
Can you provide link for the Android App? Thank you!
Everything is in the resource page . The link is below the video . For every video we have a page on our website. Or visit our website.
How to current calibrate DL24P? My unit seems not accurate
I don't remember if I have shown in the video to add or subtract value from the voltage or current, then it does not have calibration option.
Can you run it at a constant load of 100 milli amps or 0.1 ampere
I have shown all specifications and even shown when setting the values you will see the smallest value. I don’t remember the numbers. Please watch
For such a low current, just buy one of the cheap USB loads and pass through a USB tester.
The low value sense resistor in this will not allowed good a accuracy at small power levels.
excellent review, thorough and pretty clear. i accidentally hit the dislike button - i hit it again, to try to remove the dislike... i appreciate the chapters
No worries. when you click the color changes and you click again you know if it changed back. look at the Like color and you know what you have selected. thanks.
@@WattHour ok... yes, i had already clicked "off" the dislike, and after your comment, i just verified the 'like' was activated. thanks again!
Can we use to discharge 48 volt, 100 aH battery bank?
the capacity does does not matter. it can do even 1000Ah but it will take longer. You can discharger maximum of 180W. Now I don't remember if it works with 48V or not. so please watch as I have explained it fully.
@@WattHour thanks.. I did not catch the max voltage rating and on aliexpress did not mention too
Hello brother, how do I know the battery? Good or not, I bought this device. But I don't know how to use it
Hello, you measure the capacity. If you the capacity for new battery is about 95% or higher it is good. for older batteries, it might be a little less .
What is the minimum current that can be adjusted?
for setting any value, the minimum is set with digit you can select. if you select a smallest value in settings, that is your minimum. I don't have the device but I am sure I've shown it how to set the current. see how much digits after decimal point is shown.
@@WattHour ok,but the minimun current is 50ma or 100ma or 200ma?
Whoever lowest it can show.
I don’t know that’s why I am r referring you to the video.
You could also just check the specs or user manual 🙄
The resource link you provide does not exist
please check again. it was not working, I just fixed it. Please let me know if there is an issue.
Resource page not found error 404 where do we get the windows software?
Hi, yes I saw it . we moved the site to another server and saw the error. check it now. it should work. thanks
2024 APK e-tester not running with english language :/
Hi, can I please ask you a big favour? Mine has burnt out the voltage regulator due to my fault.. Can I ask you to take a picture or post the numbers on the voltage regulator underneath the cooling fan? (its the 3 legged brick inbetween the 2 bigger resistors it says 6203A on it, the rest has burnt out on mine..)
Hi, sorry. this was giveaway and someone won it and I ship it to the US.
Do you still need this info? I have a DL24 bare PCB and can check for you.
@@johncoops6897 no thx, have resolved
Thank you for posting this video. I won’t to load and see a solar panel voltage, amps, and watts max output.
At 22.55 in your video you explain how to do this. Will you please show the connections and settings
More clearly. If anyone out there can tell me how to connect and setup the DL24P to monitor and load a 100W solar panel, That will be gratly apresheated.
Thanks again for your work.
Dale
You just connect the solar panel to the input of the Load. With current set to zero, the open voltage will be shown. As you wind on more amps, the voltage will drop accordingly.
Your task is to find the point where the wattage is highest, which you can do by watching the screen. It really is that simple.
The added info in this video is about monitoring the pass-thru power between a solar panel and battery bank, which is probably not what you need to test initially.
hi... can we test car battery on this? will it burn?
Hi, it is always about voltage if you know the power. the pwoer is 180W and I mentioned what is the maximum voltage but for sure 12V is very low and it will not burn. Just watch and when I mention input voltage, that's what this device can accpet.
@@WattHour thanks sir.
Any way to turn the Bluetooth off?
Not sure as I gave away this meter. But there should be Bluetooth antenna, if it bothers you, then just cut the antenna path on the pCB. but you won't be able to to fully turn it off as even without antenna it might work for 2 to 3 meters.
Can you please share dl24 software link for android ?
Did you get it from the resource page link from the description
People be like. No, not another 12V power adapter.
Can you test phone battery capacity?
No and Yes. No because it is inside phone. Yes if you remove the battery from the phone and test it.
Good video however the "Subscribe" notice is distrustful - (correction, I meant to write, distracting).
In the 44 minutes video it is nothing. Have you subscribed? Your subscription is stamp of approval on my channel and the video will be show to other and it will help me. Thanks
And by the way this video took me a week to make.
@@WattHour My mistake that I want to make known, the word "distrustful" is completely wrong, I mean to says, distracting. My apologies.
@@WattHour Yes - I apologized and made the correction for the mistake of writing "distrustful," and yes, I subscribed.
@@WattHour My commendations and with much gratitude for your work. - Again, we can do without the nagging "Subscribe" popups.
Where can I buy it?
All videos have description below the video and I always put links to purchase there.
Nice rewiw! Unfortunately The App is a joke! Full of bugs, I say its not possibly to use
Yes . I need the app is just not user friendly.
The manufacturer ,Vendor should pay you a handsome Royalty ,……
Their manuals are miserable,…..!

not tot forget that the video was uploaded on 23......
Lengthy vid.

How to run the test such as What would be the low voltage cut off be? How do you compare the results to the battery specs to determine how good the battery still is?
Hi, I am making such videos God willing after the new year in a about 2 weeks.
@@WattHour ok tag me once you get one. Thanks.
You simply need the data sheet of the battery cells. That will give you the rated capacity as well as the cutoff voltage that it's rated at.
For LiFePO4 you probably only want to go down to 2.6V per cell. With Lipo and Li-ion then 3.0V is most common.
It really depends on what your BMS is set to, since in real life that is the maximum that you can draw down to. So, fully discharge the pack until it cuts off, then check what the voltage is. Note that the pack voltage will bounce back up after it disconnects, so measure immediately with the original device connected.
