  1. This charger is only compatible with most cylindrical Li-ion (3.7V output), Ni-MH/ Ni-Cd (1.2V) and LiFePO4 (3.2V) batteries.
  2. Please read the instruction manual carefully before use. Do not charge batteries with a current, higher than the recommended (500mA/1000mA/2000mA).
  3. Use a 12V/2A adapter to charge batteries.
  4. Take care when using the charger. Heat dissipation may cause burns.
  5. After charging is complete, remove the power cable from the device.
  6. Do not charge in extreme conditions (too high or too low temperature.)


“Slots”, LCD and their function

  1. Slots: Each of the slots can charge and monitor a battery independently. When connected to a power source, hold the “slot” button for 3 seconds in order to select either 500mA, 1000mA,2000mA charging current options. When batteries are inserted, press the “slot” button in order to select the Li-FePO4 battery type. Charging will begin within 5 seconds after the battery type (3.20V or 3.7V) is confirmed.
  2. LCD: When connected to a 12V power source, all LEDs will light up. If no batteries are installed, a “Null” symbol will be displayed followed by a 0% sign on the dashboard. The charger is capable of selecting the battery type automatically, once a Li-on battery is inserted however, Ni-Mh or Ni-Cd batteries will not be detected.
    Press the slot button once, in order to check the charging status and charging time of the batteries installed. Once charging is complete, the “END” symbol will be shown.
    The “USB” text will be shown on the display when the charger is used as a power bank. The USB and 12DC charging functions cannot be used at the same time.
