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  Bang Head.

Looking forward to senior members for help in this regard  Help Me.

Thanks and Regards

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

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

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.

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

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