Looking now for a charger that will log comprehensive data points such as voltage,capacity against time etc. so I can save the data for later comparison or make graphs of my batteries performance as I run discharge tests.
For example, a charger that would create a csv or text file of the capacity (mAh) and battery voltage every 60 seconds etc.
You might wanna look into a system that can run through a computer or something. Or see what kind of set up HKJ uses which isn’t cheap. You already have a hobby charger. Whatever it can’t do might have to step up to professional equipment if you want all that.
You know, a charger as simple as an iMax B6 actually does all that already EXCEPT, theres no way I know of to get the data extracted from the charger.
I use ChargeMaster software but it doesn’t have that kind of output capability AFAIK.
If I could tap into the output going from the USB port to the laptop and intercept that data I’d be in business.
That might do it. Thanks.
But one problem with the MC3000 is that it only handles cells.
I have other batteries that are not in a cylindrical cell format such as LiIo batteries for SJCameras and other block style batteries.
For those I need to be able to use alligator clips.
I have used cylindrical cell chargers on non cylindrical cells by running wires from either end of a piece of round wooden dowel placed into the charger slot then to the non cylindrical cells + & -
As long as the correct voltage & amperage is selected on the charge it works fine :THUMBS-UP:
None of my chargers display cell temp so I guess you would lose that feature on the MC3000 as the cell isn”t actually in the charger.
This is exactly how I connected up my SJ4000 block shaped cells to a Lii-500 so I could measure capacity & voltage of them when I first got them.
At least with the Turnigy Accucell 6 and the iNax B6 mini (pretty much the same), you can not simply connect the charger directly to a computer and get that data as far as I have researched. It requires a TTL to Serial adapter.
I did try connecting my Turnigy and IMax chargers using a direct USB cable but it didn’t work using the iMas profile in LogView.
It if does work and I just failed, I would LOVE to know that and try again.
I have Logview installed on two of my PC’s and bought several TTL to USB converter boards. I can confirm that Logview does have a driver for the iMax B6 mini but so far, I have not been successful in getting the data into the PC. Maybe I have a bad TTL converter board. I’ll keep working on it until I get it to work.
first check device manager (if you are on win32) for COM ports installed. If all drivers correctly installed you should see new COM port when you plug in usb-to-ttl adapter. You should use this port number for connection.
Then you might check output of IMAX using terminal (I use putty for this), make new SERIAL connection in putty using COM port number of usb-to-ttl adapter, then set speed (baudrate) to 9600 and open connection. Now you should see terminal window with some updated data, it should be readable, if not - try to change speed settings (115200 or 38400 or other values of standard baudrates, but I guess correct setting is 9600).
You can use also Tera-Term same as putty. Then if you get readable data in terminal - make same settings in logview (I used logview long time ago, so I am not sure how to work with it now). Please note that only one client can be connected to COM port, so putty and logview would not work with same port simultaneously.
I just checked connection from my bc6 (chinese clone). So first thing i noticed - there is setting in charger menu regarding usb connection (still it is not real usb - but ttl serial out). Connection to PC is shared with temperature sensor. So either temp sensor or PC might be connected to the device. And I was wrong about readability of serial data (it is in binary format, so all you could see in console - periodically updating simbols/signs) baudrate 9600 in my case. And I had to find out how to adjust LogView properly. So in my case it worked with setting from Bantam BC6 (which have serial connection), many other devices in LogView settings do not have serial connection but USB HID (in this case I think there is no need in usb-serial adapter, may be only some special driver for usb hid device).
Thanks again for this information.
I happen to have an Authentic iMax B6 mini and it has a built in USB port.
It also has the 3 pin temperature port.
So far I haven’t been able to get it connected but I will try other devices. Maybe the iMax B6 configuration is intended for connection to those iMax B6’s that have the USB menu (because they don’t have a real USB port built in?)
I haven’t been able to get diddly out of the iMax B6, but I was able to get a hex data stream from my Turnighy Accucell 6.
Now I just have to figure how to get that hex stream into a readable text data
Could be. Chargemaster works on both now, but I did have to remove and reattach the USB port on the IMax B6 because the connections separated.
All I can get from either (in Logview) is the Hex data stream.
Since I’m using the USB port on both, that could also be the issue. The HID USB driver doesn’t seem to work in Logview. You probably used a SERIAL connection (ie COM port) for all your connections.
There is no configuration in LogView for the Turnigy Accucell 6 so that could explain the Turnigy not working.
