The users need to provide their own power supply to operate this charger. This power supply should have an output voltage of 10V ‐15V DC and be able to provide as much as 5 Amps of current. An AC‐to DC adaptor with DC connector can work, but be sure that the polarity of the center conductor is positive. A car battery can also work. Connect an appropriate power supply to the provided alligator clips, and connect the DC connector on the other side of this adaptor to the power port located on the left side of the charger. Connecting the Battery Pack to the Charger 1. Plug in the banana plugs for the Tamiya or Deans connector to the ports located on the right side of the charger. 2. Connect this Tamiya or Deans connector to the connector found on the battery pack. 3. Connect the balancing connector coming out of the battery pack to the balancing port located on the right side of the charger (between the red and black banana plug ports). NOTE: If all of the battery pack’s wires (meaning, + terminal, ‐ terminal, and balancing connector) are NOT connected while the charger is powered up, the red “POWER STATE” LED will be flashing, signifying that a battery is not properly/fully connected and that charging cannot start. Please make sure that both of the battery pack’s power leads, as well as the balancing connector are plugged into the charger to be able to charge the battery pack. Charging the Battery 1. Once a proper power supply and a 7.4 Lithium Ion or Lithium Polymer battery pack is correctly connected to the charger, the red “POWER STATE” LED (bulb) will be lit solid, as well as one of the orange LEDs under the “CHARGE STATE” LED column, located towards the right side of the charger. 2. Once the battery pack is properly connected to the charger, the “CURRENT SELECT” button (located at the bottom left corner of the charger) can be pressed to toggle (move) through the four charging currents. The orange LED corresponding to the charging current will be alternating after every press, from “1A” charging current up to “5A” charging current, then cycling back to “1A” charging current. Charge Status Indications 1. Once the orange LED next to the desired charging current is lit, press and hold the “START/STOP” button (same as the “CURRENT SELECT” button) for about 2‐3 seconds. At this time the “CHARGE STATE” LED column will light up to the level at which the battery’s charge is currently at. You will see these LEDs slowly moving upward from “25%” toward “100%”. Specifications and data are subject to change without notice. Contact Tenergy for latest information.

If solid, this means that the battery pack has fully reached the corresponding percentage of charge (state of charge). If the highest position orange LED is flashing, this means that the charger is still in the process of charging the battery pack to that percentage level. 3. The final stage of charging is realized when the bottom three orange LEDs of the “CHARGE STATE” column are solid yet the highest level LED, next to “100%” is still flashing. 4. A completed charge is signified by all four of these orange LEDs being lit solid (none are flashing/all are solid lit). 5. The charging can be stopped any time during the charging process by a single press of the “START/STOP” button. CAUTIONS: ƒ

Please make sure to select a charging current that is at or BELOW the rated capacity of the battery pack that is to be charged. Do not leave the battery and charger unattended while charging is taking place. Disconnect the battery pack from the charger when charging has completed. Make sure that the power supply being used to power the charger can supply the charge current selected on the charger. For example, if the battery is to be charged at 2 Amps, make sure the power supply can safely supply a current of 2 Amps or higher. If the power supply can safely provide a current of 5 Amps or higher the charger can be used with any charge current setting. Make sure that the alligator clips of the charger’s power supply input do not touch each other, in order to avoid a short circuit. Disconnect the power supply from the charger when device is not in use. Specifications and data are subject to change without notice. Contact Tenergy for latest information.
