IMPORTANT PRECAUTIONS

INPUT POWER LEAD: The input power lead is located on the left side. OUTPUT JACKS:The output banana jacks are located on the right side. TEMPERATURE SENSOR JACK: The temperature sensor jack is located

directly underneath the output banana jacks on the right side of the charger. DIAL AND PUSHBUTTONS:Next to the LCD is a rotating dial plus two pushbuttons

which control all of Ice’s programming. The button marked is generally used to move to the left through the menus.The button marked ➔is generally used to move to the right in the menus. The dial has two functions: rotating the dial in both directions will scroll through menus and adjust parameters quickly and easily, and pressing down on the dial acts as another pushbutton which is often used to select different parameters on-screen.

BATTERY CONNECTIONS: It is strongly recommended to connect batteries using pre-assembled charge leads which are widely available from any hobby retailer. Two adapter leads are included, one having alligator clips for connecting racing cells to Ice, and another having a standard battery connector for connecting pre-assembled packs. For transmitters, find a charge lead that best matches the type of radio that you are charging (see below).These may be purchased through your local hobby shop.

Part # Radio Charge Leads Description

HCAP0101 Futaba®J Tx and Rx charge leads, except 9VAP HCAP0102 Futaba J Tx and Rx charge leads, 9VAP only HCAP0104 Airtronics/Sanwa Tx and Rx charge leads

CHARGER CONTROLS & CONNECTIONS

➔

HCAP0105 JR Tx and Rx charge leads HCAP0106 Hitec Tx and Rx charge leads HCAP0108 Charge leads, banana plugs to alligator clips HCAP0110 9V-style Tx connector, Futaba-J Rx charge lead HCAP0310 Banana Plugs (3 pair) HCAP0320 Heavy Duty Banana Plugs (2 pair)

Always connect the charge lead to the charger first, then the battery to the charge lead. The battery’s red, positive (+) lead must always be connected to the charger’s red, positive (+) jack, and the battery’s black, negative (-) lead to the charger’s black, negative (-) jack. WARNING! Never allow a battery’s

positive and negative leads to accidentally touch each other. This will result in a short circuit and cause permanent damage to your battery and/or charger.

It is always very important to know your battery’s exact type, rated voltage and capacity!! Failure to know these points is one of the biggest

reasons why batteries are improperly cared for and fail. A few short minutes learning the basics of battery care can easily prevent unnecessary crashes (and lost money!).Carefully read y our battery’ s label and/or instruction sheet or consult your battery supplier and determine:

1. Is the battery

type

Nickel-Cadmium (NiCd), Nickel-Metal Hydride (NiMH),

Lithium-Ion (Li-Ion), or Lithium-Polymer (Li-Po)?

2. What is the battery’s

total rated capacity?

This number indicates how much charge energy or “capacity” the batter y can store, and should always be listed on the battery’s label as “mAh” (“milli-amp hours”). Capacity is also referred to as the “C” rating. Charge and discharge currents are also expressed as a function of this “C”rating.For example, a 3300mAh battery would have a “1C”charge or discharge current rate of 3300mA or 3.3 amps. This battery’s 2C rating would be (3.3 x 2) 6.6 amps, etc.

3. What is the battery’s

nominal rated voltage?

If not printed on the battery’s outer label, consult your battery supplier or determine pack voltage as follows:

a. NiCd and NiMH Batteries: Multiply the total number of cells in the pack

by 1.20.A 7-cell pack will have a nominal voltage of 8.40 volts (7 x 1.20). A 4-cell pack will have a nominal voltage of 4.80 volts (4 x 1.20), etc.

b. Li-Po Batteries: Multiply the total number of cells in the pack by 3.70.

A 3-cell pack wired in series will have a nominal v oltage of 11.1 volts (3 x 3.70), etc.

DETERMINING BATTERY TYPE & SPECIFICATIONS

c. Li-Ion Batteries: Multiply the total number of cells in the pack by 3.60.

A 2-cell pack wired in series will have a nominal v oltage of 7.20 volts (2 x 3.60), etc.

• Do not to allow NiMH batteries to overheat! If overheated, disconnect the battery from the charger immediately and allow to cool.

• Do not attempt to use Ice’s Li-Po/Li-Ion functions with NiMH batteries.

• NiMH cells do not exhibit the “memory effect”like NiCd cells, so little cycling is needed.

• Store NiMH packs with some voltage remaining on the cells (ref er to battery supplier).

• NiMH cells have a self-discharge rate of approximately 20-25% (compared to 15% for NiCd batteries). It is important to recharge NiMH batteries immediately prior to use.

• “N”, “AAA,” “AA” and “A” size radio batteries can safely be peak charged at currents up to 1.5C (battery capacity x 1.5). High charge currents can overheat batteries and thus reduce service life, and is especially more true for smaller size cells.

Never attempt to care for lithium-polymer (Li-Po) or lithium-ion (Li-Ion) cells in the same way as other battery types! Li-Po and Li-Ion characteristics

greatly differ from NiCd and NiMH batteries and therefore require different care and handling. Always read the instructions that are included with your lithium batteries carefully before use. Failure to follow these care and handling instructions can quickly result in severe, permanent damage to the batteries and its surroundings and even start a FIRE!

• ALWAYS charge lithium batteries in a fireproof location, which could be a container made of metal or ceramic tile. Monitor the area with a smoke or fire alarm, and have a lithium approved “ABC type” fire extinguisher available at all times.

• ALWAYS provide adequate ventilation around Li-Po/Li-Ion batteries during charge, discharge, while in use, and during storage.

• DO NOT allow Li-Po or Li-Ion cells to overheat at any time, as the y can and usually will become physically damaged and could possibly EXPLODE or catch FIRE!! If a battery becomes overheated, disconnect it from the charger IMMEDIATELY!

• DO NOT continue to charge Li-Po or Li-Ion batteries if the charger fails to recognize full charge.Swelling of Li-Po cells is an indication that they are in an overcharge condition and they should be disconnected from the charger immediately.

CARE & HANDLING OF LI-PO & LI-ION BATTERIES

CARE & HANDLING OF NiMH BATTERIES

• DO NOT set Ice’s Li-Ion/Li-Po battery voltage to greater than the nominal rating of the Li-Po or Li-Ion battery, as such cells cannot handle overcharging in any way.

• DO NOT charge Li-Po or Li-Ion batteries at currents greater than the “1C” rating of the battery (“C” equals the rated capacity of the batter y).

• DO NOT discharge Li-Po or Li-Ion batteries at currents which exceed the discharge current rating of the battery , as this can often cause a cell to ov erheat.

• DO NOT allow Li-P o cells to come in contact with moisture or w ater at any time .

• DO NOT allow the internal electrolyte from Li-Po or Li-Ion batteries to get in the eyes or on skin – wash affected areas immediately if they come in contact with the electrolyte and contact your physician!

• DO NOT attempt to use Ice’s NiCd and NiMH functions for Li-Po or Li-Ion batteries.

• ALWAYS store Li-Po cells/packs in a secure location away from children.

To achieve Ice’s absolute maximum output power capabilities the DC power source must be capable of delivering at least 15 amps of current while maintaining 12 volts DC (although 12.5A will be enough for most functions). Once connected to input power, the charger will be turned on as there is no ON/OFF power switch. Disconnect the charger from input power when not in use.There are two ways to connect the charger to 12V DC input power:

1. Connect the banana plugs on Ice’s input cord directly to banana jacks on a separate DC power supply. Always connect the charger’s red lead to the power source’ s red, positive (+) terminal and the charger’s blac k lead to the black, negative (-) terminal.

2. A unique set of alligator clip adapters are included which have a female banana jack built inside the handle of each clip. Securely slide the input lead’s banana plugs into the female jacks on the alligator clips.Attach each alligator clip onto the terminals of a 12V battery or power supply noting proper polarities.

DC INPUT POWER

WARNING! Ne ver accidentally short together the positive (+) and negative (-) input connections when connected to 12V DC power. Failure to do so could result in permanent damage to the power source and the charger. It’s recommended to disconnect the charger from input power when not in use.

IntelliPeak Ice has 6 programming screens. Refer to the Main Programming Menu flowchart included with this manual for an overall view of Ice’s programming. The most commonly used screen is the “Main Memory” screen shown at the far left on the flowchart.To move to any menu to the right of the Main Memory screen (such as the Motor Break-in or Cycle Data menu, etc.) press ➔. Press to move left, back towards the Main Memory screen.

As shown in the Main Memory screen at right, and within any screen, rotate the dial to move the cursor arrow up or do wn the screen. The LCD screen shows 8 lines, but there may be more than 8 lines of features to be viewed depending on the menu. If so, continue to move the cursor downwards and the extr a lines will automatically scroll up for viewing.

As shown below, press the dial to highlight the first adjustable feature on any line. If there is more than one adjustable feature on any line, press or ➔ as necessary to highlight the proper value. Rotate the dial to adjust the highlighted value.Re-press the dial to confirm the selection.

The purpose of all the menus is as follows:

1. MAIN MEMORY: To store battery information, set battery type, set charge and discharge currents and voltages, set discharge and cycle parameters, set maximum battery temperature, and to start charge, discharge or cycle functions.

NA VIGA TING THE MENUS

➔

2. MOTOR BREAK-IN: To break-in brushed motors and adjust all related settings.

3. USER SETUP: To set various miscellaneous functions, such as fan control, temperature scale, audible tones, LCD contrast, etc.

4. DA T A VIEW:To see specific data about the operating condition of Ice or the battery being conditioned, such as input and output voltages, battery temperature, battery resistance, charge or discharge time, and enter the charge and discharge voltage graphs.

5. CYCLE DATA: To view all charge or discharge capacity information for individual cycles, or all 10 cycles.

6. STEP CHARGE SETUP: To set Ice’s “four-step charge” settings.

There are two main ways in which to configure Ice for conditioning of batteries. A memory bank is available for setting and storing pertinent information for up to 10 different batteries. After entering batter y data into the memories, simply recalling the battery’s appropriate memory number makes Ice instantly ready to go – no need to re-configure settings when changing batteries! Once a battery’s information is stored into a memory it will be saved until changed again manually.

Ice’s 10 memories are factory pre-programmed for different battery types, charge and discharge currents, etc. Refer to the “Battery Memory – Factory Settings” chart on the fold-out section included with this manual for the default settings in each memory .Also on this sheet find a large printout of a blank memory chart.Use the blank chart to record your own personal memory settings.

It is not required to use any of Ice’s memories.In such case, the Main Memory screen #0 acts as the main setup screen for manually changing the battery, charge, discharge, or cycle settings. There is no other menu for manually setting parameters or starting a function. Read further to learn more about manually setting these parameters.

To RESET all settings to the factory defaults, disconnect the input connectors from 12V DC power. Press and hold both the ➔ and buttons while reconnecting the input leads to 12V DC power. A brief initialization screen will appear, then the display will automatically change to the Main Memory screen. At this time, all previous settings will be CLEARED and reverted back to the factory defaults. Do NOT perform this reset if you do not wish to clear all

settings in the memory!

SETTING A BATTERY INTO MEMORY – SELECTING A MEMORY

➔

NAVIGATING THROUGH ALL OF ICE’S SCREENS WILL START AT THE MAIN MEMORY SCREEN. If your battery parameters match any of those

already listed in the included memory chart, simply select that memory number to quickly get Ice ready to handle your battery.

Each memory screen shows a memory number and name. With the cursor pointing to the top line:

1. Memory Number: To change the memory number, press the dial once to highlight the memory number shown in brackets. Rotate the dial to find the appropriate memory number.

2. Memory Name: To change the memory name, press ➔ to automatically show the Memory Name Setup screen as shown at right. Rotate the dial to move the ^ symbol underneath the characters in the string of letters. Press dial to highlight letter, then rotate to change the letter. Press ➔ to move to the next letter and repeat this step as desired. Press dial to confirm all selections and highlight will disappear. When done press to return to Main Memory Screen.

3. When memory name and numbers are selected, press the dial to confirm selections and the highlight will disappear.

If your battery type does not match any of the settings pre-programmed into a memory, or if you just do not wish to use the battery memories, simply adjust the settings in memory location #0, then star t the charge, discharge and cycle functions while in this screen (see next page).

Within the Main Memory screen (as shown above), rotate the dial to move the cursor up or down.Press the dial to highlight the adjustable value.Rotate the dial to adjust the highlighted value.Re-press the dial to confirm the selection. Ice will automatically store parameters into memory one second after being entered.There is no need to manually confirm settings into memory separately.

ADJUSTING SETTINGS IN THE MAIN MEMORY SCREEN

SELECTING & NAMING BATTERY MEMORIES

➔

1. Battery Info: Move the cursor next to the first line under the memory name. a. Press the dial to highlight the battery type. Rotate the dial to find the

desired battery type that exactly matches your battery (NiCd, NiMH, LiIon or Li-Po).

b. With the battery type still highlighted, press ➔ to highlight the number

of cells (for NiCd/MH) or total voltage (for Li-Ion/Li-P o).Rotate the dial to find the number of cells or voltage which exactly matches the number of cells in your battery. For NiCd and NiMH, choose from 1-10 cells. For Li-Ion choose from 3.6, 7.2, 10.8 or 14.4V. For Li-Po, choose from 3.7, 7.4, 11.1 or 14.8V.

WARNING!! NEVER set this voltage to a level that is higher than the battery’s rated voltage. Li-Ion/Li-Po cells cannot handle overcharging in any way!!

If a NiCd or NiMH battery does not achieve a true peak, the charge process will shut down automatically if the battery reaches 2.0V per cell. The maximum voltage for lithium-ion cells is 4.10V, and 4.20V for lithium-polymer cells.This feature is designed to protect the battery. For this reason, it is very important to set the proper voltage for your battery.

c. With the #cells/voltage still highlighted, press ➔ to highlight pack

capacity. Rotate the dial to find the battery capacity value which matches the rating of your battery. If the battery’s exact rated capacity cannot be found, select the capacity which

most closely

matches the

capacity of the battery .Choose from 100-9900mAh. IMPORTANT!! For

Li-Po and Li-Ion batteries,make sure the capacity setting matches the rating of the battery as closely as possible. Be very careful with batteries that are assembled in series or series/parallel configurations. Check with your battery’s instructions or supplier if unsure of the pack’s RATED capacity.

d. Press the dial to confirm all of the above settings.

2. Charge Current: Rotate the dial to move the cursor down one line. To manually adjust charge current, press the dial, then rotate to find the new charge current which ranges from 0.1A (100mA) to 8.0 amps. For safety precautions, the maximum charge current value for Li-Ion and Li-Po batteries will be limited to their 1C value. Re-press dial to confirm setting.

WARNING!! It is NOT RECOMMENDED to charge Li-Ion or Li-Po cells at a rate greater than their 1C value!! Supplying too much current to a Li-Ion or Li-Po battery can cause very serious damage (including fire!) to the batteries and the surrounding area!

3. Discharge Current: To manually adjust, press the dial, then rotate to find the new discharge current which ranges from 0.1A (100mA) to 10.0 amps. For safety precautions, the maximum discharge current value for Li-Ion and Li-Po

batteries will be limited to their 2C value. Do NOT discharge Li-Ion or Li-Po batteries at currents which exceed the discharge current rating of the battery as this can often cause a cell to overheat.Re-press dial to confirm setting.

4. Peak Sensitivity (NiCd and NiMH batteries only): This value determines the sensitivity/accuracy of the peak detection circuit. Adjustment of this value can help match the characteristics of your battery to the charger for better peak charges. For NiCd batteries the range is 5-25mV. For NiMH batteries the range is 3-15mV. A “ZEROpk” – or “Zero Volt Delta Peak” setting is also available for NiMHs which means Ice will try to detect the exact voltage peak, but the battery’s condition m

ust be good and charge currents and voltages mustbe very clean and stable for ZER Opk to function properly. A lower number means the charger will try to be more precise in finding peak charge, but in certain situations could cause the charger to errantly stop peak charge too quickly, in which case it may be necessary to increase this number to 8mV or greater (especially if using an external AC power supply on the input). Press the dial, then rotate to find the desired peak sensitivity value.Re-press dial to confirm setting.

5. Discharge Cutoff Voltage: This is the voltage level that Ice will stop discharging the battery, and is shown as volts PER CELL in the pack (not total pack voltage).Press dial, then rotate to find the correct value.Re-press dial to confirm setting.

a. Some NiCd and NiMH battery manufacturers rate the capacity (mAh)

of their batteries based on a discharge cutoff voltage of 0.9V per cell. So, to see if the battery is supplying

the amount of capacity as rated by

the manufacturer,

set the discharge cutoff voltage to 0.8 or 0.9V.This is also a good voltage for stopping discharge of “sub-C” size cells to determine their useful run-time in minutes. However, for any “A,” “AA”or “sub-C”size cells that are used to power

radio transmitters or receivers,

set the discharge cutoff voltage to 1.1V per cell to get an idea of how long the battery will power the Tx and/or Rx.Most R/C receivers are not capable of maintaining control with a 4-cell NiCd/MH battery that is discharged below 1.1V per cell. The adjustable range for NiCd and NiMH batteries is 0.1 - 1.1V per cell.

b. For Li-Ion/Li-Po batter ies, the adjustable range is 2.5 - 3.7V per cell. A

setting of 2.8 - 3.0V is recommended.

6. Trickle Charge Current (NiCd and NiMH batteries only): This is the amount of trickle charge current which will be applied to the battery only after fast charge has ended.To adjust, press the dial then rotate to find the new current. Re-press dial to confirm selection. The range is 0 - 500mA. If

charging “A” or “AA” size radio batteries (Rx or Tx), it is not recommended to set the trickle current to larger than 50mA. For sub-C batteries, the recommended trickle current setting is roughly C/20 (battery capacity rating divided by 20). If fast charge is stopped because the battery temperature reached the max. temperature setting (see below), trickle charge will not begin until battery temperature drops about 4°F (2°C) below the max. temperature setting.

7. Cutoff Temperature:Ice can monitor the temperature of the battery which is connected to the banana jack outputs.This feature is used in conjunction with Ice’s optional Temperature Sensor (DTXP4171) which can be found at local retailers. The Hobbico®Accu-Cycle™Elite Temperature Sensor (HCAP0281) and the Triton™Thermal Probe from Great Planes

(GPMM3151) are also directly compatible. Monitoring a battery’s temperature in addition to its voltage can result in the most accurate full charges without damaging the battery, and is highly recommended for use with Li-Ion/Li-Po batteries. The adjustable range is from 50 - 132°F (10 55°C). The sensor jack is located on the right side of the charger underneath the banana jacks. When properly connected to the jack, the sensor’s white wire will be on the left and the black wire will be on the right.

a. If it’s NOT desired to measure the temperature of a battery, make sure

the temperature sensor is NOT connected to the charger.

b. To change the temperature scale from Celsius to Fahrenheit or vise-

versa, see the User Setup Menu on page 25.

c. To adjust the temperature setting, press the dial then rotate to find the

new temperature.Re-press dial to confirm setting.

d. The recommended maximum temperature for NiCd batteries is 113-

130°F (45-55°C). The recommended maximum temperature for NiMH batteries is 110-125°F (43-52°C). NiCd and NiMH cells which are “AAA” size or smaller should use lower values .Start with lower temper atures first and if necessary adjust the temperature setting upward as needed in small increments and closely monitor the charge progress.

e. The maximum temperature for Li-Ion/Li-Po batteries varies by cell

manufacturer, but as a general recommendation the maximum temperature should not exceed 90-95°F (32-35°C).

For Li-Ion/Li-Po

batteries, it is better to be safe than sorry!

Start with lower temperatures first and if necessary adjust the temperature setting upward as needed in small increments and closely monitor the charge progress. Note: It’s a good idea to set the temperature cutoff approx. 5°F lower than suggested because battery temperature will continue to increase for a short time after charge or discharge has ended.
