GLOSSARY OF TERMS

Amps (A): The unit of measure for charge current.

Milli-amps (mA): A unit of measure for current, being amps (A) multiplied by 1000 and listed as “mA”. So 2.5A is the

same as 2500mA (2.5 x 1000). Or, to convert mA to amps, divide the mA number by 1000. So 25mA is the same as

0.025A (25 divided by 1000).

Capacity and milli-amp hours (mAh): The amount of energy a battery can store is called its capacity, which is deﬁ ned as how much current a battery can supply constantly over one hour of time. Most hobby batteries are rated for capacity in “mAh” or milli-amp hours. A 650mAh battery can deliver 650mA of current for one hour (650mA x 1hr = 650mAh). A 3200mAh battery can deliver 3200mA (3.2A) of current for one hour (3200mA x 1hr = 3200mAh), etc.

“C” rating: Capacity is also referred to as the “C” rating. Some battery suppliers recommend charge currents based on the battery’s “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), etc.

INPUT POWER

AC Input: For indoor use, this charger includes a built-in switching AC power supply that delivers power by connecting the AC power cord to a common 110V AC outlet.

DC Input: This charger can be powered by a portable 12V DC power source for use at the track. On the left side of the charger, connect the DC power cord’s alligator clips directly to the output terminals on the 12V DC power source. Always match polarities (red lead to red “+” terminal, black lead to black “-“ terminal). To utilize the charger’s absolute maximum power capabilities the DC power source must be capable of delivering at least 4 amps while maintaining 12 volts DC.

WARNING! Never 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.

This charger is rated for a maximum output power of 40 watts. Depending on certain conditions (e.g. if charge current is set to maximum, the maximum number of cells are connected to the output, and input voltage is low), the actual current delivered to the battery might be slightly less than the setting. This is normal.

The charger will be on at all times when connected to input power. Disconnect the charger from input power when not in use.

CONTROLS & CONNECTIONS

OUTPUT LEAD: The standard connector is compatible with most R/C car batteries. See the SPECIFICATIONS chart on page 1 for a list of additional adapters for charging battery types with different connectors.

CHANGE / START: For starting a charge, or to change settings.

S (+): For moving up through menus, or increasing the values of settings onscreen.

T (-): For moving down through menus, or decreasing the values of settings onscreen.

X : For moving to the right in the menus.

RADIO BATTERY JACK: A unique jack is located on the front edge of the charger for charging of NiCd or NiMH 4 or 5 cell receiver batteries for nitro vehicles, or even 8 cell transmitter batteries! This jack is universal – compatible with Futaba-J, Airtronics-Z, Hitec, JR, and Spektrum receiver battery connectors, and BEC type connectors.

For some transmitters, opening the battery compartment and disconnecting the battery’s lead will reveal if the battery’s own plug can be connected directly to this jack on the charger. Or, if you wish to connect the charger to a transmitter’s built-in charge jack, check with your local retailer for the appropriate charge adapter listed below:

Part number Description

GPMM3100 BEC to Futaba

Tx Charge Jack Adapter GPMM3101 BEC to Hitec® / Airtronics® Tx Charge Jack Adapter GPMM3102 BEC to JR® / Spektrum® Tx Charge Jack Adapter

WARNING! Do NOT attempt to charge one battery through the main output lead, and another through

the jack on the front edge of the charger at the same time!! Failure to do so might permanently damage the charger.

DETERMINING BATTERY TYPE & SPECIFICATIONS

Always read your battery’s label and/or instruction sheet or consult your battery supplier and determine:

1. TYPE: Is the battery a nickel-metal hydride (NiMH) or nickel-

cadmium (NiCd)?

2. RATED CAPACITY: What is the battery’s rated capacity, in “mAh” (“milli-

amp hours”)?

3. RATED VOLTAGE: If not printed on the battery’s label, consult your

battery supplier or determine the proper pack voltage as shown at right.

GETTING STARTED

1. Connect the charger to input power.

2. The “START” screen will show after power is applied. The top line of the LCD will show which of the ﬁ ve available

memories is active (0, 1, 2, 3, or 4). All settings for this memory will scroll across the bottom line of the screen. If these settings match your battery and needs, skip to the STARTING CHARGE section.

3. If the settings in the displayed memory do not match

your battery or needs, refer to the chart at right for the factory default settings for all ﬁ ve memories. To select one of these memories, while in the START screen brieﬂ y press the CHANGE button. The memory number will ﬂ ash. Press + or – to select a different memory number. Press CHANGE to activate this memory. Skip to the STARTING CHARGE section.

4. If none of the memories have settings which meet your needs, proceed to the ADJUSTABLE SETTINGS section

below to change settings manually.

ADJUSTABLE SETTINGS

1. Select the memory (0-4) that you wish to modify as explained above.

2. Press X to ﬁ nd the “BATT SETUP” screen.

3. Press T to move down to the BAT.TYPE screen. Press CHANGE to cause the setting to ﬂ ash, then press (+) or (-) to

ﬁ nd the desired battery type (NiCd or NiMH). Press CHANGE to conﬁ rm the new setting.

4. Press T to ﬁ nd the CAPACITY screen. If the charger fails to detect peak charge, this function can stop the charge

process after a certain amount of energy (mAh) has been delivered to the battery. This protects the battery from accidental overcharge.

Setting this screen to 110-130% of the NiCd or NiMH battery’s rated “mAh” value is recommended. As shown in the

quick reference chart on page 5, locate the rated capacity of your battery in the left column, then ﬁ nd your battery’s 110% or 130% capacity value to the right. Enter the desired capacity value into this screen.

Press CHANGE to cause the setting to ﬂ ash, then press (+) or (-) to ﬁ nd the proper capacity value (as close as

possible). Press CHANGE to conﬁ rm the new setting.
