Dual Charge Circuitry This charger features two individual charging circuits allowing you to charge 2 batteries simultaneously, regardless of battery chemistry or cell count. High Power Charging Circuit The G.T. X2 charger features a powerful 80-Watt charging circuit. The charger can safely charge or discharge up to 15 cells of NiMH or NiCd batteries and up to 6S LiPo batteries. Lithium Cell Voltage Monitoring The G.T.
AC-DC MULTI CHEMISTRY BALANCE CHARGER Multiple Charging Leads Included The G.T. X2 comes with the following charge leads to include the most common connection types.
Batt type/Stop To select main program To stop the operation Channel Selection To select between channel 1 or 2 Channel Lights Indicator Dec/Inc To select sub program To alter the value Start/Enter To resume or start the operation Balance block input Balance block input Charging lead connector (4mm banana female) Charging lead connector (4mm banana female)
AC-DC MULTI CHEMISTRY BALANCE CHARGER • Never leave the charger unsupervised when it is connected to its power supply. If any malfunction is observed immediately terminate the process and refer to the operation manual. • Keep the charger away from dust, water, heat, direct sunlight and vibration. • The circuit of this unit can be powered by AC 100-240V or DC 11~18 volt power source.
Pay close attention and verify the capacity and the voltage of the Lithium battery pack to be charged or discharged. It may be composed of parallel and series connection mixed. In parallel link, the capacity of the battery pack is multiplied by the number of cells but the voltage remains the same. Extreme voltage imbalance can cause a fire or explosion during the charge process. We recommend you configure the Lithium battery pack in series only.

The Charger will use the default values upon being powered up for the first time. The screen displays the following information in sequence, and the user can change the values of each parameter. The G.T. X2 charger features two full-featured chargers within a single housing. To swap between channel 1 and channel 2, press the “CHANNEL” button on the front of the charger. The two red LED lights on the front face of the charger will indicate whether the left or right channel is currently selected.
AC-DC MULTI CHEMISTRY BALANCE CHARGER This shows the trigger voltage for automatic peak detection of NiMH and NiCd batteries. The effective value ranges from 5 to 20mV per cell. If the trigger voltage is set higher, there is a danger of overcharging the battery; if it is set lower, there is a possibility of premature termination. Please refer the technical specification of the battery. (NiCd default:12mV, NiMH default: 7mV) An optional temperature probe contacting the surface of the battery can be used.
This setting allows you to change the maximum capacity that will be supplied to the battery during charge. If the nominal pack voltage is not detected and the safety timer does not expire for any reason, this feature will automatically stop the process at the selected capacity value. The Key Beep/Buzzer settings allow you to turn off the individual button “beep” as well as the musical tone that is used to alert different mode changes.
AC-DC MULTI CHEMISTRY BALANCE CHARGER The next screen will ask to confirm the settings after the charger examines the battery, giving a cell count. The “R:” value shows the number of cells detected by the charger. The “S:” value shows the number of cells you selected in the previous menu screen. If the “R:” value does not match the “S:” value, the charger is seeing a different cell count than you have selected.
When charging a Lithium battery, the charging current will begin to drop as the battery reaches nominal voltage. By using the FAST charge option, the reduction of power will not be as great as it is with a standard charge. The benefit of this is a reduced charge time. The drawback is that the pack will most likely not charge to its full capacity.
AC-DC MULTI CHEMISTRY BALANCE CHARGER Use this setting to discharge a Lithium pack. The charge current and pack voltage are adjustable using the methods shown previously in the charge and balance instructions. Never exceed 1C for the discharge rate and never use a final voltage lower than what is recommended by the battery manufacturer. The balance plug of the battery must be plugged into the charger for a proper discharge to take place.
Use these programs only when charging a NiMH (Nickel-Metal-Hydride) or NiCd (Nickel-Cadmium) battery. To alter the value on the display, press the START/ENTER key. The charge current can now be altered by using the increase/decrease buttons. The value will be saved by pressing Start/Enter key once. To start the process, press and hold the START/ENTER button for more than 3 seconds. With NiMH and NiCD packs, you do not have to indicate to the charger how many cells are in the pack.
AC-DC MULTI CHEMISTRY BALANCE CHARGER Select the sequence based on the current state of the battery. If the battery is fully charged, use the Discharge/Charge sequence. If the battery needs to be charged, use Charge/ Discharge. Press START/ENTER to confirm the setting, then choose how many times to cycle the battery (1-5). Press and hold START/ENTER to begin the process. To stop the process, press the Batt/Stop button once. Change the discharge or charge current by pressing START/ENTER while charging.
Set discharge current on the left and final voltage on the right. The discharge current ranges from 0.1A to 7.0A. Start the discharge process by pressing the START/ENTER button for more than 3 seconds. The screen will display the current state of discharge. Alter the discharge current by pressing the START/ENTER button during charging. Once you have changed the value, save it by pressing START/ENTER again. To stop the process, press the Batt type/Stop key once.
AC-DC MULTI CHEMISTRY BALANCE CHARGER The value settings in this feature do NOT affect the charge or discharge process, but rather allows you to store statistics for commonly charged batteries to speed up the charger setup time. To use this feature, you will want to change the parameters to the exact specifications of the batteries you wish to store. This example shows a 12 cell, NiMH battery with a capacity of 3000mAh.
Final voltage for selected cell type. Displayed capacity cut-off function is turned on and the current value the capacity is set to. Displayed safety timer is turned on and the duration is set in minutes. Displayed temperature cut-off function is turned on. The external temperature is displayed when the temp probe is used. Present input voltage. The battery is connected using the balance lead and the voltages of the three individual cells is being displayed.
AC-DC MULTI CHEMISTRY BALANCE CHARGER Incorrect polarity detected. Battery connection was interrupted. Short-circuit of the output termination. Input voltage is wrong. The voltage is lower than the setting currently selected. Please check the number of cells in the battery pack. The charger has an internal error. Please contact G.T. customer service. Voltage of the pack is too low to charge safely. Please check the voltages of each cell. Voltage of the pack is too high to charge safely.
