Usage:
After flashing your charger the first thing you should do is
reset the charger to default settings (go to: 'options'->'reset default' and press the 'start' button)
and then calibrate it, now your charger is ready to use.

8 mile english subtitles. programming you charger:
- select a free battery slot (indicated as 1., 2.,..)
- go to 'edit battery'
- change battery type 'Bat:'
- set battery voltage (number of cells) 'V:'
- set battery capacity 'Ch:'
- set charge current 'Ic:'
- set discharge current 'Id:'
- set time limit 'Tlim:' (can be unlimited)
- press 'create name'
charing/discharging..:
- select battery
- select program: 'charge', 'discharge'..
- you should see a 'info' screen,
(if you hear beeps, check your battery connections) - hold 'start' button for 2s to start the program
- charger is working now, press 'inc', 'dec' to see more screens
- to exit the program press 'stop'
- informations about settings
Calibration
Connect a NOT fully charged LiPo battery to the main leads
and the balance port, if you don't own a battery with a
balance connector, just connect a regular one (~4V)
to the main leads and the balance port first two pins
(pin '0' <--> Bat-, pin '1' <--> Bat+).
and the balance port, if you don't own a battery with a
balance connector, just connect a regular one (~4V)
to the main leads and the balance port first two pins
(pin '0' <--> Bat-, pin '1' <--> Bat+).
go to: 'options'->'calibrate':
- voltage calibration: go to 'voltage'
- use a voltmeter to measure voltage on all cells and the power supply voltage (Vin)
and set voltage on Vin, Vb1, Vb2, ., Vb6- only Vb1 is mandatory, battery main leads and balance port must be connected
- you need to change at least one value (this will copy V1-6 voltage to Vbat)
- use a voltmeter to measure voltage on all cells and the power supply voltage (Vin)
- charge current calibration:
- connect your amperemeter in series with the battery, use the 10A(20A) input
- disconnect balance port
- go to 'I charge'
- go to: '50mA' (100mA on some versions)
press 'start' button (current flow should be visible on amperemeter)
press 'Inc', 'Dec' buttons until the amperemeter shows 50mA (100mA on some versions)
press 'start' button to save the setting - go to: '1000mA'
press 'start' button
press 'Inc', 'Dec' buttons until the amperemeter shows 1000mA
press 'start' button to save the setting
WARNING: the battery will be charged with high current!
- go to: '50mA' (100mA on some versions)
- discharge current calibration: go to 'I discharge'
Repeat the same steps as before
WARNING: the battery will be discharged with high current! - when needed: external (or internal) temperature probe calibration: go to 'temp extern' ('temp intern')You have to set two calibration points
Done.
If you have any problems with calibration, go to 'options'->'reset default' and try again.
If you have any problems with calibration, go to 'options'->'reset default' and try again.
Troubleshooting
- After flashing I see 'options' and some strange characters in the second line (for example: squares), what should I do?
- reset the charger to default settings (go to: 'options'->'reset default' and press the 'start' button)
- I get 'calib. error': see this.
Atmega32 CPU:
- After flashing charger doesn't work (display shows squares):
- download the *.hex again, use the 'RAW' button in github
- check the sha1 sum of the file, compare it with *.sha1:
- linux: $sha1sum cheali-charger*.hex
- windows: install Microsoft File Checksum Integrity Verifier
- in cmd.exe: fciv.exe -sha1 -add cheali-charger-*.hex
- Sha1 sum is correct and the charger still doesn't work (display shows squares):

- reset atmega32 fuses using avrdude:
- windows: avrdude.exe -patmega32 -cusbasp -Uhfuse:w:0xc5:m -Ulfuse:w:0x3f:m
- linux: avrdude -patmega32 -cusbasp -Uhfuse:w:0xc5:m -Ulfuse:w:0x3f:m
