pcnt of state of charge is only possible with devices counting the current passing through (mAh).
all the devices measuring only the voltages like cellLog cannot do it. But the cellLog has other advantages like alarm output (to a buzzer or LED or what U want) and it is a data Logger .
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

Alarm port is just a 1S JST-XH port, put a bundle of the extensions from HobbyKing and cut one of the ends off to make it look exactly like the one you got in the box
MAX CELL VOLTAGE: I have seen on youtube some running two cells per slot and showing 6VDC per cell. The guide says Cell voltage range: 1.3 ~ 4.9VDC. Anyone know the real limits? Can i run a 48V pack on one celllog with 2 cells per slot?
22-JUN-2010 URGENT"
any body know if this comes with the gator plugs like the cell-log 8m(no usb)? or even if this one has the same extra plug/port (servo style)? i noticed it has same pack voltage rating. so if anyone has more details please reply, thanks in advance
:D
Read the manual download the mentionod upgrader. Read the instructions, install the driver wich came on the cd. Install update program. Select the box COM port on the update program!! otherwise it wil not find the celllogger hardware. Download the desired update file, but RENAME it!, in other words ADD the extension .BIN , otherwise the program wil not find update file.
Press update, and it will update, and have an beter menu, with the coiche of the so wanted interval change, of 0,5 to 60 secend with o,5 sencond interval.
Even celllog works fine, and show the corrected intervalls. I read two times the seconds, becouse one is the halve second, the second is the whole second! in an tabel it looks like:
log time actual time
1 4.001 0,5 second 1 4.001 1,0 second 2 4.001 1,5 second 2 4.XXX 2,0 second
Reading page 9 of the manual, it states an external alarm can be used by wiring it at the alarm output of the Cell Log. But it is not working, no power from the output when I checked with my volt meter. Does the alarm output of this thing actually works?
The alarm output is an open collector, this means there is no voltage. Open Collector closes a line, this means, on on pin you have to connect a LED with it's resistor, the other side to your supply voltage. Connect the second pin of the alarm outpout to ground. Be aware maximum current <50mA.
the input plug has only pins to connect to the Balancer cable. So every Balancer connector fits /w pin spacing .100" (2.54mm). You don't need any adapters.
If this works as shown, it would be great, but, like sikeston34m has stated, my German is ***r, except where they decide to use english. Anyone find an English version out there?
On the logview screen there is a little british flag in the upper right side. It will xlate the web page to english there - but the manual is a total different story. Frank
I can't get mine to connect to the computer. Not a Newbie here. The USB driver won't work with Vista, so I installed it on an XP Computer. The XP Machine still can't see the unit. The Driver appears to be installed correctly. I went to the software website, but I have a tough time reading German. Where can I find help?
I wrote my own program in VB6 that works on win7. The Junsi USB driver does work on win7, so the 115kBaud COM port is available. HobbyKing may need to email me to discuss options to make something available. BTW I use winXP whenever possible.
My cellog, when plugged in to either a battery or USB port, keeps resetting every three seconds. I can't get any analysis data to display on the screen. Does anyone have a solution to this problem, or is my unit defective?
This Cell-Log is firmware updateable. The manufactor, Junsi, has already said in the rcgroups forum, that there will be a new firmware released with a faster interval.
that's not right, you can change the sample rate to 0.5 sec.

24 thumbs up!
Just Installed on PC, early days yet - install not straight forward into XP had to maunally load logger - Language is German - even English is German in logger. Why can't we get Mac simplicity - install find device connect and work. This all seems disconnected, disjointed and take half a life time to fathom it out. Monitor itself works and reads batteries, but Windows XP monitoring - may take too much time away from building to bother with!
Nice voltage monitor with many modes. The 0.001V resolution seems like a nice reassurance but the noise level seems a little high considering the slow update rates. The mini-CD with drivers was difficult for my PC to read but it did go eventually, but I'd say the real problem (for non-Germans) is the 3rd party shareware that one needs to use for to recover data... I've yet to make it work, and yet to donate.

3 thumbs up!
needs usb drivers for windows 64 vista nice size for the all the feature it has. a must for the tool box good screen view easy too read
When I placed the supplied mini CD into the drive, Windows kindly asked me what I'd like to write to my blank CD... I'm more amused than annoyed, but it's an inconvenience. From what I can piece together (by randomly pressing buttons whilst searching for an English manual online) this is a great tool that will help me further understand what sort of performance I'm getting from my setups overall.
