The Hobbyking Cellmeter 6 can be used as a stand alone overal voltage/individual cell checker for 1s~6s Lipo/life/Li-Ion packs, or it can also be mounted in your model to act as both a battery checker and a low voltage alarm.....and what an effective alarm it is too, with both a large bright LED and not one, but TWO audible alarms to let you know when your battery is low, the Cellmeter 6 is a great device to prevent over discharge of your precious batteries!

I've got this alarm, but it buzz only when display is on 3rd cell voltage and on total voltage (3S Lipo), even if all the cells are below the setted alarm level.
Then, when it shows 1st and 2nd cell, it stops to buzz and starts again on 3rd cell.
Is it normal?
the problem is that I fly my plane close to me, sometime, to ear if the alarm is buzzing* if the alarm stops buzzing exactly in that time, justa because display is not on 3rd cell, I cannot ear and I fly again with low battery.
Is there a way to solve this problem?
I haave two of these which I fitted to a large multicopter. They both exhibit a problem on cold days where the reading for cell 1 reads low and the alarm constantly sounds. Both do this, when I take them inside and they warm up a bit it they read normally.
That, and they are a bit fragile.
It also depends from Your ESC low voltage cut setting.
I have my buzzers (like this one) at 3.4 V.
It would be better to set alarm at a higher level than ESC cut, otherwise You'll ear the alarm when Your plane will be gliding down, with no motor, under ESC cutting.
For example, I've setted alrm at 3.4V and ESC cut (soft cut) at 3.2V.
I have two 2s lipos on my e-savage. I thought I could simulate a 4s lipo by soldering an adapter that connects the - lead of the second battery to the lead of the first cell.
Sadly though it displays 31V with ~5V on all 6 ports.
Does anyone have any suggestions how to solve this??
Hi Lassek, Thanks for the reply, I'll probably use one of the one you recommended,If I'd only remember to set my timer each time I wouldn't need one. I really don't like taking my batteries down to 3 volts because I've has bad luck doing that wirh the cheaper batt. I use. Although I've found that by setting my ESC to slow cutoff my copters let me know when the batt. has had enough. Have a good day, Gary
Just note that the limit is settable on this baby, so you can select when it honks the horn (2.7V - 3.8V). I have it set to 3.3, works great and the batteries never get more than slightly above lukewarm. Cheers!
Provided that your battery is of LiPo type and has a balance plug that fits, yes. You program this device by setting the lowest acceptable cell voltage, selectable from 2.7V to 3.8V. If any cell goes below that limit, the alarm sounds. If the battery voltage isn't too low, and all cell voltages rise above the limit when the load is switched off, then the alarm will reset. It seems that once it has started to sound, it continues to do so for as long as any cell's voltage is under the limit (not certain because I land quickly and disconnect the load and the monitor). HTH
i dont set anything for this item. just plug the ground (GND) pin with the black wire of your battery. The buzz automatically tell you if the battery voltage is very low (about 3.5 v). but if you want to set this item, please read the manual. it's easy..
It's about as durable as a circuit board covered in flimsy plastic gets.
That said, I doubt you'll break it very easily if you tape it to some safe spot on your car with thick double sided tape.
It's not water proof in the slightest though.
I put it in a condom (for visbility), connectors pierce the condom, and fix it with velcro strap on the car = waterproof (in any case that protects water splashes) with visibility.
Hi, just wondering if I can use this unit for 2 separate 3S lipo batteries? 1st battery connected to the first half and the 2nd connected to the second half of the connector on the unit. I am using 2 lipo batteries on my glider 1st for the motor, 2nd for everything else* receiver, servos etc.
No for every cell count 1~(and above) there has to be an extra power line to complete a balance lead.
The HK cellmeter for 6s has only 7 pins and you need 8. Just get two no sense in altering an expensive lipo but attaching both to one balance lead would do the job of charging them. Go to battery chargers and get a 6s balance lead. Place in positive to negative order with the positive end of one battery lead and the negative from the other battery and connect to the middle (4th) lead port.
I dont personally have one but no sense in shipping back probably cost as much as new one try getting a mini lcd out of a calculator or something with atleast 4 digits and maybe the top and bottom line of four more digits to signify cell count, total and difference between the cells.
Oh ok I should have been more specific and gave you a "Correct Answer" lol that would be the jst-xh plug. If you go to the lipo tab to the left and open the drop down window look in the balance leads section. Select one with the male connection that will accommodate the number of cells you have. As for wiring im pretty sure all have a black lead(negative) and red lead(positive) at each end. What kind of battery you wiring up?!
I'm choosing onboard low voltage alarm. And I need to know, is this thing really so huge? 80mm x 25mm is alot for foam plane - there is no empty space. P.S. I know, there is another "Hobbyking 2-8S Cell Checker with Low Voltage Alarm" but it can not be backordered.
Darn, when I read its announcement it was late at night here and I was too sleepy to order a couple. The next morning they were already in backorder (of course), but I ordered a couple anyhow. If the specs are correct then it would be a nice safety device. But IMHO it could be a much better device if the designers would have added a simple stick in remote Led. Now you are limited to where the unit can be mounted to show the Led. But when you can simply stick in a Led with a wire and plug, then you can mount the unit in the plane or helicopter and rout the Led to an other place. It would just cost a couple of cents more.
Just like the Deutsch Powerboxes have.
Drill away young padawan!!! The force is strong in you use a saw zaw!!!!
This Product is the BMi Lipo analizer in germany , there ist costs about 13 Euros and here you can by two of them and chipment and you are under 11 Euros, and the piezo buzzers are better and very noisy than the product in germany.

dont know witch brand, but well done hk..
for the price in germany you can get here 3 pieces . for the right position in your model take a balancer extension proper to your batt. max. measured difference to my dimm: 0.0072 volt min. difference: 0.0035 volt. very good, under 10 mv. weight is 14.4 gramm. manual in english included.
was always awaiting stock back order so i cancelled it form my order

Installed inside i don't here much of the piezo as the foam covers most of the sound. The LED makes the nose of my plane blinking red but that can be only seen in night flights. If the Bright LED and the Ultra Loud twin piezo would be on a little cable to get installed outside of the plane i would rate it 5 stars.
Anyway great product for a low price! Waiting on backorder was worth it.
