CONNECTINg ThE INpuT pOWER SOuRCE
This charger is powered by connecting the provided alligator clips to connect the charger to a 12V DC power
source, such as a 12V hobby battery (HAN102) or an automobile battery. Connect the red (positive) end of
the alligator clips to the red terminal of the DC power source and the black (negative) end of the alligator
clips to the black terminal of the DC power source.
CAUTION: If you choose to power your charger with an automobile battery, never do so with the
automobile running as fluctuation in power can cause product malfunction and possibly
injury.
NOTICE: Always consult 12V battery collateral materials or Horizon Hobby before using with sources
other than standard AC wall outlet.
NOTICE: Always connect the positive red lead (+) and negative black lead (-) terminals of the battery to
the charger terminals correctly. Never reverse the positive and negative terminals. Wrong
connection will damage the battery and may cause damage to the charger.

When power is supplied to the charger, the charger will beep and the cooling
fan will begin to run. The display will default to the “Voltage” indicator.
Connect the battery to the charge lead. Use the included charge adapter
(figure 1) if you are charging a radio battery. The charger will beep and the
battery voltage will be shown on the LCD.
Notice which LED is flashing (figure 2). If it is not the LED indicating the
chemistry of the battery cell you intend to charge, press and hold the Display
mode button (figure 3) until the correct LED is flashing.
WARNING: Under no circumstances should a Li-Po battery be charged in
the Ni-MH or Ni-Cd modes. The charge will not terminate fast
charge, personal injury and extreme damage may occur.
The LED will automatically start flashing faster at this point and the LCD
display will automatically switch to the “Amps” mode (figure 4). Press the
Current Adjustment buttons (figure 5) to increase or decrease the charge rate.
Lower capacity radio batteries should be charged at no more than 1 amp.
Higher capacity radio batteries (over 100mAh) may be charged at 2 amps.
Large sub-C cell sport packs may be charged at up to 3.5 amps, and the
higher quality (matched cell) performance packs may be charged at higher
rates. Consider that the higher charge rates may lower charge times but
may not be as efficient as lower charge rates.
Press the Start/Select button (figure 6) to begin fast charging the pack. The
Vision LCD (figure 7) will begin to flash while the charger analyzes the
battery condition and automatically determines the cell count.
NOTICE: If the charger notices a problem with the battery pack, such as
shorted or weak cells, fast charge will not begin and the beeper
will sound multiple times. Discard the battery pack.
As the battery becomes charged, the segments on the Vision LCD will
increase. Once the pack is fully charged, the LCD will be fully illuminated.
The charger will beep indicating the charger has entered a safe trickle mode.
(See Trickle Charge selection). Press and release the Display Mode switch
to view the real-time charge voltage, peak voltage, charge current and
charge time displays.
