SPECIAL FEATURES

Operating software optimized for ease of use and maximum safety

The user can adjust each of Prodigy 620 DUO’s settings and parameters. However, the Prodigy 620 DUO also features an AUTO charge function that sets output current during the process of charging or discharging; this can prevent fire or explosion caused by overcharging due to incorrect charger settings, particularly for lithium batteries. If an error is detected at any point in the charger’s operating, the unit will stop the charge or discharge process and an alarm will sound.

Integrated lithium battery cell balancer

The Prodigy 620 DUO features an individual cell balancer built into the case. There’s no need for an external balancer.

Individual cell balance discharging

While discharging lithium batteries that have been plugged into the integrated balancing port, the Prodigy 620 DUO can monitor and balance the voltage of each cell individually. The process will end automatically and an error message will indicate if the voltage of any single cell is abnormal.

· 06

SPECIAL FEATURES

Compatible with all types of lithium batteries

The Prodigy 620 DUO is capable of charging various types of lithium batteries, such as LiPo, LiFe, and Li-Ion.

Fast charge and storage charge modes for lithium batteries

Fast charge alters the rate of change in charge current to reduce the duration of the charging process, while the storage charge mode brings the voltage of the pack to a suitable level for long-term storage.

Maximum safety

The Prodigy 620 DUO uses Delta-peak sensitivity to automatically terminate the charging process once the battery’s voltage exceeds the specified threshold; this prevents the battery from overcharging.

Automatic charging current limit

For safety and extra protection against battery damage, a user-determined maximum current limit can be set when charging small-capacity NiCD or NiMH cells with low internal resistance.

Capacity limit

The charged capacity listed on-screen is calculated by multiplying charging current and charge time. If the charging capacity exceeds this user-specified limit, the process will be terminated automatically.

Temperature threshold*

The battery's internal chemical reaction during charging or discharging may cause the temperature of the battery to rise. If the user-specified temperature limit is exceeded, the charging process will be terminated automatically.

*This function is available by connecting optional temperature probe, not included.

Processing time limit

The user can set the maximum charge/discharge time. If the time limit is reached, the process will be terminated automatically.

Programmable memory

The Prodigy 620 DUO can store up to ten (10) different charge/discharge profiles for your convenience. These stored profiles can be recalled quickly, with no additional program required.

Continuous charge/discharge cycles

The Prodigy 620 DUO can automatically cycle batteries up to 5 times; this is useful for refreshing and balancing old batteries after long-term storage.

WARNING AND SAFETY NOTES

Never attempt to charge a battery that is:

- made of different types of cells.

- made of cells from multiple manufacturers.

- non-rechargeable.

- not among the types listed as compatible with Prodigy 620 DUO (NiCD, NiMH, LiPo, LiFe, Li-Ion, or lead-acid).

- faulty or damaged.

- fitted with a charge circuit or protection circuit.

- installed in a device, or electrically linked to other components.

- incompatible with the available charge current.

Before beginning any charge or discharge process, you should complete this checklist:

- Does the selected charger program match the battery type?

- Is the charge/discharge current correct for the battery size and type?

- Does the battery’s cell count match the indicated voltage? (Example: A 2S LiPo pack has a nominal voltage of 7.4v)

- Are all wire connections secure? Any breaks in the circuit?

Charging Notes

During the charge process, a specific amount of electrical energy is fed into the battery; this amount is equal to the product of the charge current and the elapsed charging time. Never charge a battery at an amp rate higher than that specified by the manufacturer. Only batteries that are expressly stated to be capable of quick-charging should be charged at a rate higher than its standard charge current.

Use caution when connecting the battery to the charger’s output terminals; red is positive, and black is negative. Be sure to use wire of adequate size, as well as high-quality, gold-plated connectors to reduce internal resistance, as this is essential for Prodigy 620 DUO to work properly.

WARNING: Connecting a lithium battery to the charger incorrectly may damage the battery, and can even cause a fire!

Always refer to the information provided by the battery manufacturer when determining charge current and charging time. Lithium batteries should only be charged according to the manufacturer’s instructions.

· 09

WARNING AND SAFETY NOTES

Special attention should be paid to the connection of Lithium batteries. Do not attempt to disassemble the battery pack. Lithium battery packs can be wired in parallel and in series. In parallel connection,

the battery’s capacity is calculated by multiplying single battery capacity by the number of cells. Attempting to charge cells with different voltage levels that are wired in parallel may cause fire or explosion. ProTek R/C recommends charging lithium batteries in series only.

Discharging

The main purpose of discharging is to deplete any remaining battery power, and requires the same care and attention as the charging process.

A lithium battery should never be discharged further than its minimum voltage; this may cause a rapid loss of capacity or even a total failure. Always set the final discharge voltage to avoid deep-discharging lithium batteries. Frequent full discharging should be avoided if possible; consider using a larger battery, or charging the battery more often.

NOTE: Lithium batteries do not reach full capacity until after its first several cycles, which serve as a “break-in” period that normalizes the battery’s capacity.

Rechargeable NiMH and NiCD batteries, however, develop a “memory”; If they are only partially depleted before recharging, the battery may remember the point at which the discharge process stopped and use only this portion of its capacity.

CONNECTING THE CHARGER

Connecting the Charger

The Prodigy 620 DUO comes with male 4mm Bullet connectors attached to the power INPUT cables. These cables are appropriate for attaching directly to most high-quality AC-DC power supply units, such as the ProTek R/C "Super Pro 1000" (30V/40A/1000W). Also included are large Terminal Clips with matching 4mm female bullet connectors for attaching directly to 12V car batteries. It is critically important that you use either a fully charged 13.8V car battery or a high quality AC-DC power supply in the range of 15V to 18V DC output, with minimum current rating of 60A to insure reliable performance.

4mm Bullet Connectors plugging to Super Pro 1000 power supply directly

Using terminal clip attaching to car battery

To take advantage of the Prodigy 620 Duo's full power capability, the power source should be 15V-18V DC, and output power should be capable of 1000W or higher. A low quality DC power source may damage your Prodigy 620 DUO charger. We recommend our PTK-PRO-1000W-SP - ProTek R/C "Super Pro 1000" DC power supply. (Part # PTK-PRO-1000W-SP)

Connecting the Battery

Before connecting the Prodigy 620 DUO to a battery, it’s essential to verify that the charger’s parameters match the battery to be charged or discharged; incorrect settings may damage the battery and can cause a fire. To avoid short-circuiting the battery pack, always connect the large leads to the charger before connecting to the battery. When disconnecting, unplug the battery first and then the charger.

Balance socket:

Before charging a LiPo battery in Balance Charge mode you must first connect the battery’s balance plug to the charger’s balance plug port. Check the plug’s polarity before connecting to prevent damage to the battery. (See photo below).

This photo shows the correct way to connect your battery to the Prodigy 620 DUO while charging in the balance charge program mode only.

INITIAL PROGRAMMING SETUP (USERS SETUP)

Initial Programming Setup

When powering up your new Prodigy 620 DUO for the first time, its charge parameters will be set to their default values. You may change the values of each parameter and then store these new settings to recall later.

To change the value of a specific parameter, press the “Start/Enter” button to make it blink; when blinking, press the INC or DEC buttons to change the parameter to the desired value. Press the Start/Enter button once to store the new setting.

User set up starting screen.

This screen displays the nominal voltage of the Lithium battery type currently selected: LiPo (3.7V), LiFe (3.6V) or Li-Ion (3.6V). It is very important that this setting matches the battery that will be charged, as an incorrect value may damage the battery and can cause a fire.

The Prodigy 620 DUO will automatically detect the cell count of a Lithium battery at the beginning of a charge or discharge process; however, Lithium batteries that have been discharged too deeply may be difficult for the Prodigy 620 DUO to detect. A timer may be set to terminate the process early if the cell count cannot be detected; normally, the default setting of 10 minutes is sufficient, though you may extend the time limit for larger batteries. Please note that setting the time limit too high may cause the charge or discharge process to finish with an improper cell count setting, which may damage the battery or cause a fire.

The Prodigy 620 DUO uses Delta-peak detection to terminate the charge process of NiCD and NiMH batteries. The Delta-peak sensitivity can be adjusted from 5-20mV per cell; too high of a value may damage the battery due to overcharging, while too low of a value may cause the charger to terminate the process prematurely. Please refer to the battery manufacturer’s instructions. (NiCD default: 12mV NiMH default: 7mV)

INITIAL PARAMETER SETUP (USERS SETUP)

When using the optional temperature probe to monitor the battery, the temperature cut-off can be turned on or off. When turned on, the maximum temperature of the battery can be set. If the battery reaches this temperature the charge process will be terminated automatically.

A battery pack may become hot when cycled through multiple charge and discharge cycles. When cycling a battery pack, this value will insert a delay (1-60 minutes) between charge and discharge processes to allow time for the pack to cool.

Trickle charge mode for NiCD and NiMH batteries can be turned on or off. When turned on, the charger will supply the desired charge current to achieve a full charge without overheating the battery after it has been fast charged.

The Prodigy 620 DUO has an additional safety timer that begins when a charge process is started; the safety timer can be set to prevent overcharging in case of a faulty battery or incorrect charger settings. The value of the safety timer should be set high enough to allow sufficient time for the charge process to finish.

The capacity cut-off function regulates the maximum capacity that will be supplied during the charge process. Should the Delta-peak sensitivity not terminate the charge process, nor the safety timer, the capacity cut-off will stop the charge at the selected capacity value.

Both the beep that sounds when a button has been pressed and the beeping during operating that indicate different mode changes can be turned on or off.

When an automobile battery for power input, you may set a low input voltage cut-off to protect the battery from damage. If the input voltage drops below the specified value the charge process will be terminated.

The brightness of the LCD screen can be adjusted.

LITHIUM BATTERY (LI-ION/LIPO/LIFE) PROGRAM

Lithium Battery Charge Overview

These programs are only compatible with Lithium batteries with nominal voltages of

3.3V, 3.6V, or 3.7V per cell. These batteries require a charge technique called the CC-CV (constant current-constant voltage) method. The charge current varies according the battery capacity and performance.

A Lithium battery is charged at a constant current (A) until it reaches the final charge voltage of 4.2V per cell (B). After this point, the voltage is kept at a constant level and the residual charge takes the form of a declining current curve (C) until the cut-off point (D), when the charge current equals 1/10 of the battery’s capacity. At this point, the battery can be disconnected from the charger and is ready for us.

The final voltage of the charge process is also very important, and should match the battery’s chemistry (LiPo: 4.2V Li-Ion: 4.1V LiFe: 3.6V). The charge current, nominal voltage, and cell count must be correct for the charge program to charge the battery.

Charging Lead Acid Batteries

This mode is only suitable for charging lead-acid (Pb) batteries with a nominal voltage between 2-24V. Because lead-acid batteries can only deliver current lower than their capacity, the charge program reflects this; lead-acid batteries cannot be charged at a current higher than 1/10 of the battery’s capacity. Lead-acid batteries cannot be fast charged, and you should always follow the instructions of the battery’s manufacturer. A lead-acid battery’s chemistry can make it difficult for the charger to detect a full charge, so it’s important to use the capacity cut-off to protect the battery from being overcharged.

To begin discharging, you must set the discharge current (0.1-10.0A) on the left to and nominal voltage (0.1-25.0V) on the right to match the battery being discharged. Press and hold the Start/Enter button for more than 3 seconds to start the discharge process.

COMMONLY USED TERMS

Commonly used terms Final charge voltage: the voltage at which the battery's charge limit (capacity limit) is

reached. The charge process switches from a high current to a low maintenance rate (trickle charge) at this point. From this point on further high current charging would cause overheating and eventual terminal damage to the pack. Final discharge voltage: the voltage at which the battery's discharge limit is reached. The chemical composition of the batteries determines the level of this voltage. Below this voltage the battery enters the deep discharge zone. Individual cells within the pack may become reverse polarized in this condition, and this can cause permanent damage. A, mA: unit of measurement relating to charge or discharge current.1000 mA = 1 A (A=Ampere,mA=Milliampere) Ah, mAh: unit of measurement for the capacity of a battery (Amperes x time unit; h = hour). If a pack is charged for one hour at a current of 2 A, it has been fed 2 Ah of energy. It receives the same quantity of charge (2 Ah) if it is charged for 4 hours at 0.5 A, or 15 minutes (=1/4 h) at 8 A. 'C'-rating: Capacity is also referred to as the 'C' rating. Some battery suppliers recommend charge and discharge currents based on the battery 'C' rating. A battery's '1C' current is the same number as the battery's rated capacity number, but noted in mA or amps. A 600mAh battery has a 1C current value of 600mA, and a 3C current value of (3 x 600mA) 1800mA or 1.8A. The 1C current value for a 3200mAh battery would be 3200mA (3.2A). Nominal voltage(V): The nominal voltage of the battery pack can be determined as follows;

-.NiCd or NiMH: multiply the total number of cells in the pack by 1.2. A 8-cell pack will have a nominal voltage of 9.6 volts (8x1.2)

-.LiPo: multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in series will have a nominal voltage of 11.1 volts (3x3.7)

-.LiIo: multiply the total number of cells in the pack by 3.6. A 2-cell LiIo wired in series will have a nominal voltage of 7.2 volts (2x3.6)

-.LiFe: multiply the total number of cells in the pack by 3.3. A 4-cell LiFe wired in series will have a nominal voltage of 13.2 volts (4x3.3) If the nominal voltage of the battery is not printed on the battery's label, consult your battery manufacturer or supplier. Do not guess the rated voltage of battery.
