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.

Operating Guidelines

Connecting the Input Power Source

This charger is powered by 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.

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 (figure 6) and the LED will begin to flash.

• P ress the Display Mode Switch until the amps are displayed on the LCD.

• P ress the Current Adjustment buttons (figure 5) 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

Figure 1

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

Figure 2

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.

Figure 3

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:

Figure 4

4.00 amps X (18 minutes / 60) 0.3 hours = 1.2 amp/hours (X1000 = 1200mA/h)
