Heltec Internal Resistance Tester HT-RT01. Not what I was expecting...

- In close preparation of our next project, we will have a look at the #Heltec HT-RT01 Internal #Resistance #Tester . It is a workbench measurement instrument with supposedly high precision and resolution and the ability to send all battery data to the PC where you can set filters to analyse your measured battery data!
I was really looking forward of testing this device and use it for our next project where we will build a new battery. I thought we can use it to quickly analyse and measure all 16 cells and have them showing in a list on my computer as well.
This device and review was one of the biggest disappointments of all devices I have ever tested on the channel. The software is so bad designed, that it is pretty much unusable. The device itself looks great but has some major design flaws that I was asking myself if nobody has tested this before releasing it to the market.
It is the first device receiving 0 frogs! Zero...
I would still recommend buying the handheld internal resistor tester as we have used before. It works and is reliable:

Ah Andy, this video made my day. I was rolling around laughing at your reaction to the probe cable lengths. Love your videos!
Andy ! you should know by now that anything Heltec Don't work properly or as advertised 🤣 . I would have ended the video with a lump Hamer going in it for a nice dramatic effect . But as usual another great video to watch and make me smile. Thanks Andy!
🤭
now you know why they made the cables so tight to insert. it helps to make it easier to drag!
Hahahaha, that is true!😄
Use a 500A/50mV current shunt (0.1 milliohms) to check accuracy. You can use your Victron smart shunt.
Great Idea... my YR1035+ shows me exact 0,1mΩ. Thank you!
Andy, sei il numero 1! Con questo video mi hai fatto morire dal ridere! 😂
Wow! Tough review for poor Heltec. But, they deserve it for seemingly not really even using the device before mass producing it and sending out the door. Love the comical review Andy. Entertaining as always.
Well said!
Exactly what I was looking for. I'm ordering two !
You get a discount!😆
Andy thanks for the good laugh i was about to die when the computer started going DA-da i would have yanking cords thinking it was about to blow up
That was the only video idea I could come up with for this device and software.
They expect you to put the Amazon box on workbench, then the Heltec box on top, THEN the tester! Perfect!
Danke. Ich musste die ganze Zeit lachen😂. Herrlich!
Wenigstens etwas...😆
Thanks for this Test. Danke für das amüsante Video - viel gelacht über diesen Müll
What you purchased was a bench top instrument, usually placed on a shelf above the bench top so the display would have been easy enough to view. Being a bench top instrument, it is not meant to be moved to take a measurement and the leads are too short for your purposes but remember having longer leads causes it (1) to be more susceptible to noise (the instructions mentioned the possibility of interference from cell phones?) and (2) increases the resistance in the leads (which would likely be somewhat compensated for with the Kelvin probes). The software was a big disappointment, not having an automatic sensor or switch on the probes to allow you to move from battery to battery without having extraneous garbage readings doesn't fit what otherwise appears to be software meant for bulk testing.
But how do you measure a lot of batteries in a timely manner if the instrument sits still on a shelf? You would need some sort of belt which feeds the batteries to the right location. For me, the whole product design is flawed not to mention the software...
nice video for a bad protect but just wondering if you can move the graph with your mouse by click/hold the mouse and slide to the left maybe the software not to move that automatically
No idea. I have uninstalled the skier software already.
Thank you! Extension of the wire harness should not be a big deal. They are using Kelvin probes. But the deviation of the R-Value is a fundamental flaw.
I would add a button as a trigger and start a voice recording as well. Then you could read your cell number and have a link to the recorded R-Value. Or add a small QR-Reader to the probe to link the cell number to the recorded meter reading.
adding all these things or I can just use the handy hand-held device we had for years.
@@OffGridGarageAustralia Of course, you, me and the users can do. But the developers of a brand sparkling new goundbreaking meter should deliver more to bring a real advantage over the handy hand-held meter.
feb07’24/1305h 🇺🇸 Herr Andy, Danke. The length of the probe Cable is short, minimizing resistance to read IR accurately. If the length is required to be extended; I’m sure there could be a potentiometer to adjust, by first reading the resistance of the new cable. That’s my inference. You’d not want to go to that length! The display is 90% similar to 1035+ and I’m certain the electronics are too.
I’m not being negative, but this device is unsuitable for normal use. Let me thank you for introducing 1035+; 3~4 years ago. I use it every time, it’s very user friendly, portable and detects dud ones. Have a nice day ahead. Auf wiedersehen.
The device has Calibration built in, so firstly, maybe it needs calibration out of the box (this is bad!) and secondly, you could very much change cables and calibrate the tester for those new cables.
You could also get an RC3563 and have the same thing in a handheld Li-po powered device for 20% of the cost of the Heltec unit.
"4-wire method" is the magic word
Your comments show you don't know what the 4-wire test actually does.
Looks like software is for a robotic tester on an assembly line or a very fast, precise person on a line. If they had a button on longer probes, putting info on file would be handy for large amounts. Years ago, befor lifepo4's became readily available, I saw people use battery testers that printed a sticker to put info right on 18650, that would be a great way, otherwise the cells would need be in some order (as numbered) for the files to be used later.
Yes, it could be for an automated setup but clearly not a s bench instrument. The whole product design and usage just does not make sense. It's kind of pointless.
9:40 lay the cell flat 🤷🏻♂️
if they are in a box?🤷♂️
Because you have to push the testers onto the cell, this would need to be supported from the back side of the battery laying down flat. It really needs to be upright so you can push against the work bench. Not ideal to lay it down flat. Longer cables would make the most sense...
This is not a product meant for bringing around but have handy on stand by next to your bench power supply. Did you check group mode on the app? Maybe it makes it possible to trigger a measurement? As in a group meaning more than one battery while live is for checking just one? I could easily see Chinese translate something like that to group. Since the device aparantly are using a serial interface I’m quite sure it would be simple for an programmer to make an application that’s useful if the price of this is right and it’s actually measuring correctly.
Perhaps "monitor mode" is to measure a single cell over time and "group mode" is to measure multiple cells to group/match for batteries
We will never find out, I guess!
The fact that they are even selling an internal resistance tester is amazing to me. I wouldn't trust the 5 digits they advertise, but the 0.5% sounds correct. In anycase, the HT-RT01 is designed for a test bench where the unit is elevated on a shelf, over the battery.
And who moves the batteries within 6s? It is totally unpractical to use like this.
@@OffGridGarageAustralia Conveyor belt or rollers if its a factory and they need to test a lot of batteries. It's probably used at a sorting station.
I don't know which of the two devices is the more accurate but obviously something is way off somewhere. I doubt either them has even 3-digit accuracy. You might need lab-grade test gear to figure out the actual internal resistance.
Thanks!
Thank you for your ongoing support, Sree.
wonder if the plasic over the display screen blocks vision a on screen ?
maybe nG stands for "no good"
Just a clear screen protector film, works the same shitty way with or without.
Five frogs for the Video,
minus one frog for the product!
But thanx Andy for your hilarius Testing...
Liebe Grüße nach down under
Thanks for watching!
Hi Andy! Heltec looks like RC3563 tester. The same display, menu and software. But with big box and shorts wires.
The RC3563 also has a USB port as well.
Funny review!
This video made me smile 😂
Yes, me too actually😄
Hi , you can open the unit and normally it should have a pot on the contrast pin 5 on the lcd , you can adjust that to be readable ( it also may have resistors .. so you must play with that )
Thanks for the tip, but yeah, nah. I won't use that device ever again...
Dear Andy, could you PLEASE make a video of DC breakers? (And post it on you website?) This information is missing. It is a must have for DIY.
To show what? I have this topic in many of my videos already...
Thank you Andy i have a lot of laughs
I had them too actually. I really wanted to make this a great review for their product but the more I tested, the more I laughed...
I haven't even finished the video and already know this thing was not thought through.
I want my Da Da!! Most of us would prefer our Ma Ma. I know I would.
Time flies in China. Ten seconds is like six. Who would have thought.
This could spawn a game show with the switching of the cells close to the cabling and removing the cell just tested.
I think the skier on the computer ap is perfect. Everything goes downhill after you unbox the unit.
You should hang it below a shelf/or even on a shelf abouve the height of the cells then the cables hang down. If you extend the cables the resistance could influence the measurement.
This would make no difference in the purpose of this device...
Why don't put the battery down on the bench! Thx really good Video!
That is not the point.
If this meter is really intended for production lines, it should have an external trigger so measurements only occur when the test fixture is in its intended measurement position instead of requiring parsing logs and aligning timestamps with the production line to figure out which measurements go with which battery.
As for the LCD's readability, you could try using a polarizing filter on your camera to improve contrast.
Also, you can easily fix the short probe cable length my splicing, it won't affect a proper 4-terminal measurement. In a production environment, you would build your own rigs, kind of makes sense they wouldn't bother much with usability-testing bundled probes that won't get used much in the industry beyond testing the unit out of the box if at all.
Yeah, I could extend the cables, it would not matter as there is no current going through. Just need to keep them twisted...
If jk did this the thing would be super accurate but both probes would be 8ft of green cable, its always turned on, the screen would be a blank piece of plastic so you need an app on your phone to get any info, you would then get an option of buying an external LCD screen and an optional plug in power button on pigtails, and also a comms port in a strange protocol and a 50 page document on how to read it but no info on wiring to be able to connect any thing to it without guessing..... and i'd still buy it lol
Hahaha, great analogy. I like it!
Hahaha, it almost sounded like duke nukem "self-destruction in two seconds".... Awesome.
Andy, You made me laugh.
especially when your German accent comes back when you start to get annoyed
I have a German accent???😉
but now - you have 2 meters reading different values ...... which one do you trust?
A western manufactured meter.
I just apologise, how many times try to drop a box like this..😂
0:06
Great Video again!
Thx a lot.
6 secounds is a cycle time.. just for a beginners..😂 so.. never be a line operator in China..😂😂😂
Great review as always Andy 😂 but come on, why are you suffering in the heat? With that amount of power & batteries, surely you could do a ' solar powered split unit heat pump air conditioning ' video to keep you, your batteries (and your SPAT) cool. There are lots of diy units out there to choose from.
No DIY units here in AU...
can you try 17 cells charging @ 3,45v ? on multiplus ?
No
haha, I was waiting for the imperial march :D
You remember, right?
@@OffGridGarageAustralia of course, I remember. 😁
🎉🎉🎉
🥇
You kill me. Laughed so hard with the lead lengths.
haha, at least something 😄
Du-Du is the VW beetle horn 😂 for everyone remembering jimmy bondi
Yes, correct. I need to find that clip!
0 frogs 😁
Andy 🍻 and forget it 😉
Yep, it's boxed up again and I had a 🍺
At least now you know why the cables are so tight...
Lay the cell on top of the tester?
Not allowed!
❤❤❤❤❤❤
There name is very correct - Hell - Tec.
I didn't know that Heltec made such fancy paper weights
Me neither, but they have. It's great!😄
Maybe you can't expect to use every feature of the unit, for every measurement application.
USB length, easily fixed.
Test lead length and spec by design. Owners manual normal Chinese standard. (No surprises). 230V supply, means suggested use on testbench with shelving. If model number has -AU prefix, they know you'll just balance it on a plastic wrapoed 6-Pack of beer....no problem.
G'day Andy how's things got question been really busy forgot about my battery it was full (two years my bad)😢now something happened now is this correct it went to sleep it was 5 v now I put the charger on it played up for awhile then started charging went back to 12.4v still got charger on for a bit but did I wake it up or did I f@#$ my battery 😢
I can't really understand this one long sentence... what battery do you have?
@@OffGridGarageAustralia lol my back goes bad for the last two years I go through stages but this time my sciatica got pinched between my discs so I was 80% paralyzed but all good now sort of but I wanted to go boating so I checked the battery 5v hooked up to the charger well it carried on (got a solarking battery with our favourite active balancer lol)then out the blue the charger worked and charged up the battery so I learnt doing bit of research that a lithium iron can go to sleep so how do you fix it get a 12v source amps don't matter here hook up to negative first then this is very important just quickly touch the positive with the positive wire and just a sec and it wake everything good learning curve but it was cool to learn thank god it happened to me but if you look at it all I'm doing is jump starting the BMS(I think) same as you with the BMS starting up sorry not good with video and two years is a long time lol go lithium iron batteries as if it was leaded it would have died
Like# 325? - You need a shelf to place it on!
angee angee angee angee angee
this voice i so nice i would buy it for that
It's all yours. I'll send you mine!
Hey andy, could the test leads be the wrong way around? Red and black on the positive lead were reversed a oppose to the negative lead..
I don't expect any improvements but give it a chance 👻
And you sure you don't need to calibrate it, but to what??😂
Maybe to the other tester🤪
I would calibrate it to an ice cold S.P.A.T...
Cheers!
It OK but I prefer my Agilent 4338B low ohm meter, you can still find the on Ebay
Test frequency: 1 kHz
Test Signal level: 1 µA, 10 µA, 100µA, 1 mA, 10 mA rms
Maximum voltage across sample: 20 mV peak

Parameters measured: R, L, X, |Z|, ∅, R-X, R-L, |Z|-∅
To measure DV Volts ill use the DMM6500 6 1/2 diget with its 8 channel scanner card.
They must have had it on a shelf above the battery..... and the software is useless.
They didn't really practice test this thing. Especially with a stationary tester, the cables need to be extra long.
Seems to be an RC3563 tester stuck in a box by Heltec. Not even their own device, just rebadging someone else's product. Just checked pricing also, and they cost 5 times the RC3563. They play a joke on the unwary
I would LOVE to see a teardown!.
It's definitely a clone of RC3563. Menu is identical, but device name LQ1060S does not even match this Heltec ....
They have more than one Product from other Companys with just their Lable, inclusive the the known one JK BMS in the Black Case ;).

btw, Andy, your TR1035+ should also be able to connect to PC via USB. but it need be patched with CP2102 chip. details at "YR1035+ enabling serial port to read data" thread at secondlifestorage
What software would you use?
@@CollinBaillie unfortunately have nothing to say more, than refer to mentioned thread. TS mentions Mega Cell Monitor integration, that's probably it
The same software that heltek uses might work.. because it seems to work the same way (sends info on serial 2 times per second) .. just need to have a usb to serial (uart 3.3v) that this software wants..or maybe we can change the usb info (vendor:id).
Lay the cell down on its side?
Not the problem...
😎
What do you expect it called Hell Tech.
Whoops, I mean Heltec.
LOL
Ah, that's where I read the name before😉
The hand-held test probes are less accurate than the coaxial probes provided with some other testers. Both the test current injection point & the voltage measurement point need to be as close as possible to provide accurate 4-wire resistance measurements.
The question is, how accurate you need to be in a DIY environment...
Battery cells in battery packs get out of synch for two reasons: the energy capacity in kWh (better than the usual AmpHr matching) is mismatched, & the internal resistance is mismatched. The series connection requires each battery to match 1/16 of the energy delivered for a 52 V pack (the weakest battery sets the limit for the pack) & the terminal voltages over the discharge curve along with the AmpHrs sets the energy delivered by each battery at full discharge. Internal resistance determine the terminal voltage because all batteries deliver the same current. So how much unused energy (kWh) are you willing to leave in your battery pack because it's inaccessible when the weakest battery runs out of energy? The better the match, the better the useful energy from your pack. So I suppose you could say that the absolute internal resistance level is less important than the match between battery cells. In that case the absolute value read by your meter is not important as long as it has the same error bias for all measurements. Any errors caused by probe positioning errors are not likely consistent, hence the recommendation for coaxial probe tips.@@OffGridGarageAustralia
I don't like Helltech ! However , It Is Appropriately Named ........ Nick , NavyBlueSmoke , LST -1195
If your battery has an internal resistance that _needs_ any of the 2-200 ohm ranges, congrats, you now have a REALLY expensive heating element.
🐸🐸🐸
The Classic mobile tester is Cheaper, the display is better to read, probes are longer and if you want, you can even buy the 18650 adapter for a few bucks too 😂
I see it the same way.
In case you can put the cell on the top of the tester lol
Should take it apart...
To do what? I spend a few hours already testing it...
I bet the HT-RT01 is simply a RC3563 in another case and 5 times the price 😂
That could be true!
This device is not for end users but for battery factories , behaving like a backyard mechanic. Only for professional use
With an automated feeder belt which brings all the batteries in the right order and speed.
hahahahahaha man o man i lol so hard when you were riding that Tester like a bucking bronco. Wouldnt it be easier to lay the battery flat down.?That product is NG (No Good)
Yeah, NG=not good!
Of course, you can lay them flat, but that's not what the manual showed, and it is still totally impractical to use with 16 cells on a workbench.
@@OffGridGarageAustralia you are right about the 16 cells on the bench, that wouldn't work very well if at all.
At least there an option for du-du 😂
I miss the good old Da-Da😆
this is why probes stick tight to the holes so you drag it all over the place
Heltec --> technology out of hell 😉
The Ac time has nothing to do with you measure batteries. Put it on 0.5 sec. It just a update freq.
Pretty sure Acq means acquisition, acquisition time (delay).
USB A-A, Don't these people ever learn?!
ANDY!!!!!! PUT TGE CELL ON ITS SIDE.......
Hi, Andy lay the cell on it's side
That does not fix the problem...
Hi Andy this person stoled my Identity cuz I didn't write that
OMG. Watching you struggle with the short test leads was like watching someone walk up to a door and start pushing and not being able to figure out that the door pulls open.
Lay the cells flat on the bench and the leads will reach. You can even stack several cells and test them one after the other that way.
🤦♂
You didn't get it, ey😆
@@OffGridGarageAustralia Oh, I got it. But play it that way if you wish.

@@alexandershevchenko489 no it's why you have the 2 wire (so 4 in total)
@@Irilia_neko AFAIR, even in such case they should be twisted between themselves to reduce interference. which is difficult, if possible at all. correct me if I'm wrong
@@alexandershevchenko489 no the problem you are talking about is for measuring capacitor, the length and size of the cable is important, because of the capacitance produced between the wire. In this case the only thing important is the loss in the cable it's why the two cables, but generally you have a small one and a big one, but they just have used the cheapest part possible. This product was never tested in this state, this looks like an early prototype, because the things in acrylic is clearly a bad idea, way too fragile for a professional environment
Sit it above the cells on a bench
That is not the point here...
Heya, wel it seem that the heltec tools ( almost all of them) are not doing what is sayed that they should do. ( for me I don't like this firma )
Yeah, experience was very mixed for me as well...
Junk and i question if it's really a true 4-wire measurement. Do a teardown video, let's see how the front panel terminals are wired and connected to the PCB.
That is a great idea...
Lay the battery down so the leads will reach.
We can't.
10 C in the day is too hot for you 😅
ArecU there? We need BMS for 200Volrs BMS.
Do U have solutions?
No
Lay the cell flat on the table.
16 of them? And then, drag the device on top of the cells? It may slide a lot better maybe😄
Elongate the leads and/or 3D print a stand.
and a battery feeder...
Looked nice until you turned it on and the display is total crap… they need to spend another $2 and install a good display.
Or adjust it if that is possible at all.
put the device on a shelf maybe?
And then? How do I measure 16 batteries?
I agree with you@@OffGridGarageAustralia. I put in my comment before the video got that far.
Unpack the cell, put it on the bench, contact the probes, repack the cell - repeat !
