Fuses
This charger is protected by a 2 amp glass fuse. If you need to replace a fuse, your
local hobby retailer should be able to supply one. You can also find replacement fuses
at automotive stores. Always replace your fuse with a new fuse of the same rating. VISION PEAK™

Operating Guidelines
Connecting the Input Power Source
This charger is powered by either connecting the AC power cord to a 110V AC outlet or
using 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.
If you choose to power your charger with an automobile battery, never do so with the
automobile running!
Setting the Charge Perimeters
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 cells 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
charger will not terminate fast charge and 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.
NOTE: Lower capacity radio batteries should be
charged at no more than 1 amp. Higher capacity radio
batteries (over 1000mAh) may be charged at 2 amps.
Larger sub-C cell sport packs may be charged at up to
3.5 amps, and higher quality (matched cell) performance
packs may be charged at higher rates. Consider that
the higher charge rates may lower charge time 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.
NOTE: 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.

Introduction
Thank you for purchasing the Dynamite®Vision Peak™Ultra AC/DC Peak Detection
Charger. As the most technologically advanced charger in the Vision line, this
charger has all the same great features the Vision chargers are famous for but also
now charges 1- to 3-cell Lithium Polymer (Li-Po) batteries. Now you can monitor
the fast charging process through the charge indicator on the LCD display as well
as charge time, current voltage and peak voltage. Also charge 1- to 8-cell Ni-Cd and
Ni-MH packs with an automatic cell selector.

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 section).Press and release the Display
Mode switch to view the real time charge voltage, peak
voltage, charge current and charge time displays.
Adjusting Charge Current During the Fast Charge Period
Once the fast charge period has begun, the charge
current is locked in.
To change the charge current:
• Press the Start/Select button and the LED will begin to flash.
• Press the Display Mode Switch until the amps are
displayed on the LCD.
• Press the Current Adjustment buttons to adjust the
charge current.
• Press the Start/Select Button to resume fast charge.
Volts
The voltmeter function (figure 8) allows you to monitor the
real time charge voltage of the battery to determine the
battery’s charge state. The voltage increases as the battery
becomes charged.
Peak Volts
The Peak Volts (figure 9) records the highest voltage that
the pack has reached during the charge period. The higher
the battery’s average voltage, the more power it can
deliver. Fully charging and discharging a battery pack
(cycling) can increase the Peak Voltage, translating into
longer and faster runtimes.
Trickle Charge
When the LED is flashing, a low current pulsed trickle
charge is being applied to the battery. Trickle charging
safely maintains the charge capacity until you are ready to
use the battery and helps equalize the cell voltage.
Boost (Repeak) Mode
After the battery has peaked and enters the Trickle Charge mode, you may enter the
Boost mode by pressing the Start/Select button. The word “Boost” will be displayed
on the LCD (figure 10). This mode allows you to fast charge the battery at 1 minute
intervals after the battery has peaked to “top-off” the pack.
Charge Timer
The Charge Timer records the fast charge time in minutes (figure 11). To determine
the charge capacity applied to the battery, multiply the charge time in hours by the
charge current in amps.
Example:
4.00 amps X (18 minutes / 60) 0.3 hours = 1.2 amp/hours (X1000 = 1200mA/h)
