Hi All,

I had purchased a new Turnigy Accucel 6 balance battery charger from Hobby King. Charges is working fine but not entering in Calibration mode.

Voltage shown by the charger is lower (.25 V) as compared to  measured by multi meter  .

Looking forward to senior members for help in this regard  .

Thanks and Regards
Mohan

Hi Mohan,

can you describe the process you are following to bring it under calibration mode?

this process is common for MOST of 4 button chargers as most of them follow the same binary and almost same set of microcontrollers.

Thanks,
Sandeep

Thanks for reply.

As I Learnt from various videos available at you tube, pressing and holding the "Start" and " Dec" button and power on.

Looks you are following the process right.

Press start ( keep it pressed) then press decrease/status (keep this also pressed), turn on power, this should enter into calibration mode.

this is the standard process, mostly, we just miss keeping the buttons pressed (these get released), just watch this closely and you should be able to bring it under calibration mode.

Thanks

anyone with same problem?? and any solution?

Accucell 6 DOES not go into calibration mode. ( for some it does)

I was purchased this charger from Hobbyking. I informed and sent a video of process to HK and they credited amount in my account as warranty settlement.

I still has this charger, working fine, only I add the .25 volts in reading of charger. You can also find the + or - ve difference and read the readings.

fine, but how do you put batteries into storage voltage?

Which multimeter are you using to check the voltage ? You cannot trust the cheap chinese multimeters for this.

On Accucell 6 or similar there is LiPo Storage setting, similar to lipo charge. It will automatically bring your battery to storage voltage(by either charging or discharging) which is around 3.8V per cell for LiPo/LiIon.

I would suggest flashing this firmware : https://github.com/stawel/cheali-charger which gives some extra features. First make sure you model uses atmega32 or M0517LBN MCU.
