Balance Lithium Discharging
Connect battery to power up iChecker v.3
The default lithium cut-off voltage is 3.7v/cell. To adjust the discharge cut-off voltage refer to
the parameter settings listed above. To change the values of the cut-off short press the Cell
button to decrease the value, to increase the value short press the MODE button.
To start the discharge process press the MODE / DISCHARGE button for at least 1 second and
“discharge” will flash on the screen once startup has begun. The iChecker v.3 will slowly
toggle showing each individual cell’s voltage or short press the CELL button to toggle through
each cell’s voltage individually. Once the battery is discharged the iChecker v.3 will sound a
constant double beep sound.
WARNING:
Do not a leave Lithium battery connected to the iChecker v.3 after the battery has discharged.
The iChecker will continue to use the battery’s power to stay powered up using the batteries
power, irregular balance and damage to the battery could happen. On startup if a single cells
voltage is lower than the cut-off adjustment the iChecker will not go into discharge mode and
will be indicated by double beep sound error.

Connect battery to power up iChecker v.3
The iChecker v.3 has a built in smart detection to tell the difference between all lithium cell
types. Depending on the battery’s voltage the battery type could be incorrect, short press the
TYPE button to toggle through the types. Choose the correct type to view the remaining
capacity % correctly.

Nickle Battery Testing
Connect battery to power up iChecker v.3
Upon start up the iChecker v.3 will display the battery total voltage, cell count and remaining
capacity. Depending on the battery voltage the cell count could be less than what is displayed.
Press the CELL button to choose the correct amount of cells the battery has, the remaining
capacity % will be correctly displayed. The iChecker v.3 cannot display individual cell voltage
for mulitple nickle cell batteries.
Servo Testing
Connect 5-6v battery to the power in port to power up iChecker v.3
Upon start up the iChecker v.3 will display the voltage of the battery to supply power to the
servo. Plug servo into the servo test ppm out port located on the left side of the iChecker.
To start servo testing hold the CELL (servo test) button for at least 1 second. Move the PPM
dial located on the left side of the iChecker to manually operate the servo, short press the
CELL button to center the servo. Press the MODE button to start auto servo movement, to
adjust the servo speed move the PPM dial.
ESC Testing
Connect the esc signal line to the PPM port located on the left side of the iChecker. A power
source is needed to power your esc. Plug the battery into the esc and the iChecker will power
up. The function for the esc is the same as the servo testing. Please note that it is not recommended that a motor be connected to the esc for testing as it will cause your model’s motor
to run.
