  • Do not upgrade to v2101 if you need to use Monitoring Suite

    There is a bug in the firmware update that prevents the charger from communicating with the PC. I tested my charger (running on v2101) with versions 1.2, 1.3, and 1.5 of the Monitoring Suite with the same results - the charger and PC do not communicate. The constant in all cases was the firmware version installed in the charger which indicates this is where the problem resides. Note that prior to updating the charger, the PC and charger communicated and Monitoring Suite functioned properly.

    PolaronUSA has confirmed there is a bug and are waiting for the fix from Germany.

  • Regarding Monitoring Suite

    As Mark has written before, there is a software bug that prevents the charger from communicating with the PC propely.
    We are working on it with high presure.

    As soon as we have a solution, we will post a new Update.

    If you need the monitoring suite, do not uptdate and stay with the old version.

    Kind regards,


  • Graupner_Charger_Monitoring Suite problem solved

    I have solved this problem. From PC_Software_V1.2 I take file called "Graupner_Charger_2017_08_31.cpf" and rename it to "Graupner_Charger_Profiles.cpf" and put it in the main directory grstudio 4.7 ( replace old one ). Then start Graupner_Charger_Monitoring Suite v1.5. It fine work for my Polaron EX1400 with Firmware Master 2.101 Slave 2.102 on Windows 10,

  • Polaron Pro problem hours and date

    hello, the date and time of my pro polaron does not stay in memory.
    every time I turn it on the time and the date resets; however the name of the user I have saved remains in memory.
    Is this normal?
    Do you have a solution ?

  • Answer "Polaron Pro problem hours and date"

    Hello Mr Rothstein,

    maybe the memory battery is empty. You can send the charger for inspection to our service department.

  • Balance Problem

    I have only use EX1400 for less than 2 months. I have update to the current firmware right after I have receive the unit. I use the charger mainly for RC Car which is 2 cell HV LIPO both standard and shorty size. The battery is from Arrow, 6000 mAH for shorty and 6600 mAH for standard size.

    After charging the battery for approx. 20 cycles, I have the issue that the battery become hot during charging and from the display it indicated that the volatage of the battery is not balance somce time different by .05V. I always charge with the the current rate of 1C and try 10A for 3 cycle inorder to test that the charger could work.

    One battery destroy after 22 cycle (become fat, i mean expand in size) The second one does not look good and will be damaged soon.

    For testing propose, I have swop my battery with friend's charger (while charging at my ex1400 the battery become hot), surprisingly on the other charger the battery is not hot at all.

    Please advise on what shall I do. Any recommendation on firmware, etc.

    Thanks Siri

  • Polaron EX voltage calibration

    I started to notice even though I charge my 2 cell LIPO battery to 4.20 per cell the battery was coming off at 8.48 to 8.54 volts when checked with a calibrated fluke tester. I decided to update the firmware which I really struggled with as nothing i did seem to work. It didn't help the firmware software package was in German and the instructions weren't very clear on what to do. So I don't think I've updated it correctly and now it seem that the power supply screen is cycling on and off. Please help.


  • Answer "Polaron EX voltage calibration"

    Hello Craig,

    please send your Polaron to our service departemt. There's something wrong with the power supply.

    Kind regards


  • Voltage Calibration

    Is there any chance to implement to software the funcionality:
    1) Voltage Calibartion
    2) IR measuring on not charged battery pack

  • IR and voltage calibration

    Voltage calibration is done in the factory. It can not be done by the user.
    IR measurement is only possible at charging or discharging.
