Accurate cell voltage monitor for up to 8 cell battery packs and also measure NiMH, NiCD, PB battery voltage. Voltage alarm configurable with over voltage and low voltage settings. The CellLog 8M is pre-calibrated at the factory to ensure accurate cell voltage readings, though customers can change the Alarm, Tone, LCD, Start and voltage settings and also change back to default factory settings.
Specifications:
Lithium (LiPo/LiIo/LiFe) battery cell count: 2~ 8 series Pack voltage range: 4.0~43.0VDC (USB can provide lower voltage 1.0V) Alarm pack voltage range: 0.1~4.3VDC Cell voltage range: 1.3~4.9VDC Alarm cell voltage range: 1.3~4.9VDC Voltage display resolution: 1mV Current loading of test: 8mA Maximum voltage for alarm port: 50VDC Current drain for alarm port: <500mA Weight: 18g Dimensions (L X W X D): 62 X 39 X 12mm (2.44 X 1.53 X 0.47in)
How do you use the little alarm plug? Do you actually need it for it to beep when your cells hit the voltage you put in? For example, If I set my Low voltage alarm setting to 3.3v and I just have my battery plugged up to it without the extra alarm plug and the meter reads 3.29 volts will it beep?
I almost bought one of these for logging in flight voltages.. BUT - no logging function. Also this thread (*******bit.ly/WVRr72)reports it doesn't talk with current PCs (Win7/8.. not even Vista, only XP).
BTW: I have an old Cell-log 6: it *should* log - but does't... and of course doesn't play well with Windows 7. though it does have a current (amp) meter that I find useful.
I'm going to pass on this product... though I'm still looking to find a decent lightweight & inexpensive voltage & current logger?!
the alarm port is just a transistor output, so the power in normal condition, should not cross over to the cell ports at all. be careful tho, you can only have 500mA worth of current going or else it will fry something
You do not need an 8S cable. This Voltage monitor has an inbuilt connector that is compatible with 2S-8S LiPos. All you need to do is plug the charging lead of ur LiPo into the CellLog 8M and it will work.
Found the answer myself...just plug the nimh into same pins as the lipo's go, if pin doesnt fit on? there yer outta luck and have to remove clip and use alligator plugs to wires....
There were 2 alligator clips in the box. Touch the red clip on the positive of the NiMH and the black clip on the negative of the NiMH. I use this monitor for NiMH, LiPO and even AA batteries from the store.
Depends on how high you fly. It's not that loud as you would expect and depending on the wind, you may not hear it all. I would recommend to get the battery monitor (2s,3s,4s,etc) here on HK which is super loud and you can really hear it, plus you can permanently install the battery monitor.
I use this monitor mainly to check the status of each cell after each flight.
Yes, it´s setable. The loudnes depends on how far you fly, but this device hava a nice "open colector" output in paralel with the buzzer where you can conect anything you want as an alarm, lights for example.
No, i doubt it, i cant remember seeing percent, but there is a graph for each cell, if it is full, the graph will be at the top of the screen, if low, then below
Can anyone help (New to this) but cannot find any instructions on how to use it. All i want is to measure 2s reciever batterys and a 3s transmitter battery. I just dont know where to start??? or where u use the disc supplied for what, am complete amature to lipo teckno any HELP would be gratfull. Rolly11
Just plug in ur LiPo's JST plug into the Slot on the receiver (note the numbers). Then after a few seconds, the voltage should appear. A manual is available in the FILES section. (If i answered your question, give credit pls)
I don't test it, although I suppose so.
Cell-Log 8M it's like a tester, use balance plug to get values from each cell of your battery, only this, independient of the type of battery.
This monitors through the JST-XH balance plug. you should be able to combine the 2S balance plugs on each battery into a 4S balance plug and then connect that to the Cell-Log to monitor both batteries
Thanks a lot. I intend to buy a splitter 6s ->2x3s and modify it into 4s -> 2x2s leaving the two extra cell balance plugs useless. After all the cell log takes up to 8 cell balance plug, so there is no problem.
Dear Frank, what do you mean step by step? I intend to have the batteries connected to the cell log constantly during the run time and when the first pair finish then connect the next one etc.
Do HobbyKing have extra connectors for the alarm port? For instance, are these right? http://www.hobbyking.com/hobbyking/store/uh_viewItem .asp?idProduct=9700

Does the monitor show the % of the battery charge left in the pack , like the Smartguard does? Just bought one to use as an instant Voltage and percentage reader in the field, please tell me it does and all my mate that paid almost $30 for the smartguard will be p***ed :)
Well i can alteast now answer my own question as my order arrived today. This device does not show total % left in lipo pack, whilst this is a pity it is not terminal and i can still use the Voltage reader. Just makes things more complicated.
It does tell you the total voltage of the pack, along with the voltage of the individual cells, the highest and lowest voltage, and the voltage difference between cells.
It doesn't specifically tell you the percentage of the charge left in the pack, but with a little math skills you can easily figure it out.
on a 3S pack:
100 = 12.60V
90 = 12.45V
80 = 12.30V
70 = 12.15V
60 = 12.00V
50 = 11.85V
40 = 11.70V
30 = 11.55V
20 = 11.40V
10 = 11.25V = 11.10V
To get those numbers into a
The 8M version does not come with a USB port for logging or upgrading the firmware. Only the 8S version has that feature. More information on the two versions can be found at: www.link
Comes with just wire, you must solder on your own connections. Use whatever connections you have standardized to, whatever is on your batteries and ESC
i Have the Junsi cellog 8 and its great, why bother to provide a product with a log file when you cant download it to view it?? Are we sure theres no USB port on this version. Is there an image that you could upload to show the difference. regards Dave
*Starman97: The data says battery pack 43V max. I think your battery may exceed 43V during charging. Also I think that the 43 volts should be equally distributed over 8 battery blocks.
Very good data logger that measures up to 3 digits after the decimal point. The Cell-Log comes already calibrated perfectly from the factory. I checked it with a high quality voltmeter "Fluke". The measured voltages and I can find a measurement uncertainty of only .005 to .007. This is extremely accurate! For the price can not beat! Ideal if you no longer at the airfield just know if the battery is charged or not! Top quality! Highly recommended. The other version of this comes with a log as well where you can store the log and downlad to your PC later.

9 thumbs up!
Sehr guter Datenlogger, der bis auf 3 Stellen nach dem Komma misst. Der Cell-Log kommt bereites bestens kalibriert ab Werk. Habe mit einem hochwertigen Flucke Voltmeter die gemessenen Spannungen ueberprueft und habe eine Messungenauigkeit von nur 0,005 bis 0,007 feststellen koennen. Das ist extrem genau! Fuer den Preis nicht zu schlagen! Ideal wenn man am Flugfeld nicht mehr genau weiss ob der Akku aufgeladen ist oder nicht! Top Qualitaet!
