Introduction

Thank you for purchasing the Dynamite

Vision Peak

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

™

Ultra AC/DC Peak Detection

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.

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.

Figure 1

• 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.

Figure 2

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.

Figure 3

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.

Figure 4

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

Figure 5

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)
