Спасибо огромное за полезное видео! У меня есть такой же cellmeter-8 но я его полностью не использовал. Теперь все мне понятно. Хороший финал видео. Да, такое может быть у каждого. Хорошее чувство юмора! Спасибо!
Hi Stephen. I have the Cellmeter 8 and it is very useful. The only issue I have is the servo tester. I set it up, exactly like you, using a lipo 3S 2200mah and a 20amp ESC with BEC but at the time of plugging in the lead at 2:42, a continuous alarm sound starts and none of the information on the screen is shown. I have checked the plugs that go into the "servo power in" and "servo test out" to ensure they are the correct polarity. Do you know what I am doing wrong please. Would appreciate your thoughts. Thank you. Peter
Hi Peter. I'm sorry I can't say what the issue with your unit might be. If you set it up the same way I did it should give the same result. Unfortunately my RC stuff is all in storage right now as we do some renovations on the house, so I can't try to replicate what is happening with your unit. The only thing I can suggest is trying another ESC or some other 5v source. Good luck Peter. Steve
@@fennz Many thanks for your prompt reply. No worries, I'll keep seeing what I'm doing wrong unless it's actually the unit that is faulty. All the best and thank you.
If you don't set the servo testers range you could end up overwriting your servo and strip the gears.It happened to me.I set mine at the 1500 max range,not 2500.Just a word of warning.
States no less than 4 times on the box that it can do balance, and at 90ma.. i think you should have tested it. It also mention discharge, but you covered that already Thanks for video.
Awesome video! Have you ever figured out how to test a 1s lipo/liion? According to docs, it should work when supplying 5v to the nicd port. When I try though, it shows the „NiCd“ voltage (my power supply), and pressing TYPE won‘t change the battery type. Am I just overlooking the obvious, or is testing 1S just not possible in reality? Thanks a lot!
Just got Cell Meter 8, alone, from Amazon. Meter seems OK but won't work with AOKoda module, bulb harness, etc. to fast discharge lipo packs. Returning for replacement, hoping replacement will work with my stock AOKoda setup.
Hi Stephen, lot of thanks for these very clear and instructive explanations! If I only want to balance the battery cells , I choose discharge and as value I select approximatively the voltage of the lowest cell? And for simply balancing must I add a discharge source (like your lamps) or can this device also do it with only battery connected?....If yes will it not be warm? Friendly, Michel from France
Hi: I see you have some experience with the cellmeter 8, and I was wondering if you could answer a question - when NOT connected to the 150W discharge module, does the "discharge indicator on the cellmeter blink or stay solid? The reason I ask is I bought 2 cellmeters and 2 discharge modules, but cant get the discharge modules to work (led on solid, no light bulbs light). and the discharge indicator on the meter is not flashing either. t 1st, I thought that was because the meter wasn't "detecting" the module, but one happy owner told me that the discharge indicator on his meter flashed no matter what. Any knowledge of any of this? Thanks! Dave.
for some reason my discharge does not blink nor the green light on the black box, unhooked than hooked all back same, which one is faulty do you think? current battery 99% indicated
Thank you! Just bought one yesterday at my local hobby shop, had an idea of how it worked but dont have the adapters an connections i need lol asked they man at the counter if this will work with deans plug or the traxxas rc batterys an he was just confused lol
Ohh actually i realize i bought just the device, it didnt have any of the plugs an connectors? Do u know if amazon supplys ? My hobby shops useless the old men there are very rude an unhelpful for some reason.
I suspect that red wire on jumper connects to pin marked "S" on meter and black wire to pin marked "--" with no wire to pin marked "+". It looks that way in the video. Tried this on two different CellMeter 8's, from Amazon, Model #LSDZ1, neither worked with AOKoda fast lipo discharge setup. My similar Hobbymate meter and AOKoda discharge combo is working well discharging lipos. Go figure! I kept the replacement Cell Meter 8 to check remaining pack capacity via the graphic and for servo testing.
Tried to discharge 2 cell Li-Po battery exactly as described in the video, but it doesn't work. The green light doesn't start to flash when I select "discharge" on CM8, and bulbs are not lighting up. Tried everything, switched red and black cables, connect in different order, nothing helps.
Do I have to have all them connections to discharge my batteries? Or can I just plug my battery in than press discharge? Will that work also r not? Need help..
Hi ! it seems to be called Cellmeter 8 cause many of the other cheap "capacity controller" cheap devices you can find with the same type of format and enclosure are 7 pin in the right side and this one has 8 pin and the extra servo connector, i'm not aware of the differences in detail, just starting to get some info, thank you !
I thought that with discharging modul the lamps go of, instead of that, they discharge the batt.further..if you dont watch the voltage goes too low..any sense?
Just like in this demo, I found the cheap Chinesium clone Cellmeter 8 to be a bit flakey and often crashes with random garbage on the display. Also when testing servos, don’t plug the servo in until you set the correct mode and trim pot or it ends up driving your servo hard beyond its limit during the change of modes. For that reason, I have now ordered the genuine Hyperion Sentry 4 at more than twice the price. Reliability costs money.
@@fennzand yet this video shows that selecting the servo mode is flakey numerous times and has to be repeated to get it to work. So there is a lot of ‘lemons’ around. That’s the problem with playing Chinese craps, you take your chance and you get what you pay for.
Sir...i have this cellmeter 8 device..when check my servo....using 5.3 volt in the input ..all works well. But if i stops any action in my cell meter 8 for 5-8 seconds...it automatically disconnects itself from the power source. I didn't got it... whether it's the inbuilt protection function or my cellmeter 8 is defected one?? Can you please tell me sir....i am confused😥
Hello Mr. Stephan Fennell, It was a nice video. I am doing an Electric Vehicle project. I want such type of display for my 48 V 35 AH battery pack of Li-ion chemistry. It is possible to connect this and use for our application.
Hi, A 48V battery has ...13 S and this device can control 7 S max. Perhaps control the 7 first S and then the 6 others. If it's only for voltage control (to search a balance issue) it's possible. You need two external JST male connectors, one for 7 cells and one for 6 cells....But a multimeter will do the same quickly. And I don't know if this little device can balance such a big Pack if you want to do it... Normally your necessary included BMS must do that. if you want to control the discharge by using, simply install a little voltmeter on your pack.
When you order, you need to be careful wrt whether you're buying JUST the CellMeter 8 blue unit by itself, which is most of the ads I've seen, or the blue CM8 unit PLUS the black interface to the LiPo battery, which also provides the bulbs, socket, and the two wires, which as Stephen pointed out, you don't need the one. You could just use the blue CM 8 box to discharge but it will take an incredibly long time. In the original AOKoda unit, that unused wire was the only wire used in that version.. They changed the blue unit, which I don't like nearly as much as the original. I have both. I just received the CellMeter 8 version today from Banggood and have already tested it out, thanks to Stephen's video. I don't think the AOKoda branded unit is available anymore, even though that was what was pictured on Banggood's website.
@@valkyriep you dont need the bulbs or adapter to discharge. you do just plug the balance plug in and hit discharge like normal. it takes FOREVER but it works the same way
Thank you Jose. It's available at Banggood: www.banggood.com/AOKoda-CellMeter-8-battery-checker-with-Battery-Voltage-Balance-Servo-Checker-Tester-p-1196808.html?rmmds=myorder&cur_warehouse=CN
the discharge portion of the video is VERY misleading. you dont need the bulbs and adapter. you just plug in the battery and hit discharge. it takes WAY longer but it works the same way as in the video.
This was so graceful and educative. I just ordered for this gadget and you really helped me know how to operate it. God bless you my good sir!

Great video the instructions you get with it May as well be in Chinese! I only got the unit itself and it didn’t come with the extra bits .
I didn't get the extras you got.Where did you buy your cellmeter 8 at?

0:18 you have it in your hand and have looked at and still cant figure out why its called cellmeter 8? how many cells can it meter? 8 cells

this does 8 cells, the others are 7 cell max
The cellmate 8 front panel states that its a battery voltage capacity check, I did not see that demonstrated. Am I misunderstanding it?
Hi Ricardo. At about 12:10 I demonstrate how to check both the overall voltage go the battery & the individual cells. I hope this is useful to you
Voltage is not a capacity, Ricardo asks about mAh calculator or Wh calculator durning discharge.
I still discharge mine without the lights why do you hook those up it does it without that.
I thought that with discharging modul the lamps go of, instead of that, they discharge the batt.further..if you dont watch the voltage goes too low..any sense?
It is important to keep an eye on it & disconnect it when the beeper goes off
It would be the best...but discharge current does not run through the device which only "reads" voltage fall for beeping.
Is discharging it the same as balancing it? If not, how do you balance the battery charged or not?
I would use a balance charger to balance a battery

I am sorry but I can't replicate this. Can you get a 5v source rather than 5.3? Perhaps the .3 is triggering protection function
@@fennz ok Sir....i will check it....do you have any insta id ?..i then share a short video on it..if it's still create problem..in 5v then

too bad it doesn't do battery resistance levels
I bought this and thought I could check the capacity of my cells.
Are you not able to?
the discharge portion of the video is VERY misleading. you dont need the bulbs and adapter. you just plug in the battery and hit discharge. it takes WAY longer but it works the same way as in the video.
I bought one and it didn't come with anything else.
And what this thing is called i want to take for me. I want to store a lot of 18650 cells, but it takes a long time with only Cellmeter
consisering how many times you said lipo i feel the need to inform you that its pronounced like liposuction
So to discharge you need that black box or can you discharge the battery plug straight into the CellMreter 8 ?
