Welcome to cheali-charger!

This project is an alternative firmware for the G.T. POWER A6-10 200W Lipo charger.

Don't use it if You don't need to! (not everything is implemented yet).
This is a early version so be very careful. Use it only if You can not calibrate your charger with the original firmware.

Any feedback is very welcome!

• Li-ion, LiPo and LiFe:
  • charging
  • fast charging
  • charging + balancing at the same time (not implemented yet)
  • discharging
  • balancing
  • storage
  • storage + balancing
• Ni-Cd and NiMH - not well tested!
  • charging, method: -dV/dT
  • discharging
  • cycling (not implemented yet)
• Pb (not implemented yet)
• Internal resistance display
  • single cell resistance
  • whole battery resistance
  • battery leads resistance
• Internal and external temperature monitoring
• Overcharge and overdischarge monitoring
• Input voltage monitoring
• Memory for 32 batteries
• CALIBATION!

Please CALIBRATE the charger before use! Always use the external temperature probe!
(if You like your house ;) )

• G.T. POWER A6-10 200W (http://www.hobbyking.com/hobbyking/store/__7386__GT_A_6_10_200W_Balance_charger_discharger.html)
• IMAX B6 Charger/Discharger 1-6 Cells (comming soon)
• .... - any suggestions are very welcome

dependencies: cmake, avrdude, avr-libc, gcc-avr

user@~/cheali-charger$ sudo apt-get install cmake avrdude avr-libc gcc-avr

user@~/cheali-charger$ ./bootstrap
user@~/cheali-charger$ make

flashing with USBasp:
 
user@~/cheali-charger$ cd src
user@~/cheali-charger/src$ ./progUSBasp.sh

Now You should see a "ChealiCharger welcome" screen.

Done.

Connect a NOT fully charged LiPo battery to the main leads and the balance port.

go to: "options"->"calibrate":

• balance port calibration: go to "B0-2", "B3-5"
  • use a voltmeter to measure the voltage of all cells
    and set the values in the appropriate fields.
• output voltage calibration: go to "B0-5 to Vout"
  • press the "start" button for a few seconds
    (this will copy the voltage from the balance port)
• charge current calibration: go to "Icharge"
  connect your amperemeter in series with the battery
  • go to: "50mA"
    press "Inc", "Dec" buttons until the amperemeter shows 50mA
    press "start" button for a few seconds
  • go to: "1000mA"
    press "Inc", "Dec" buttons until the amperemeter shows 1000mA
    press "start" button for a few seconds
    WARNING: the battery will be charged with high current!
• discharge current calibration: go to "Idischarge"
  Repeat the same steps as before
  WARNING: the battery will be discharged with high current!

Done.

Have fun!
