The X4 has four independently adjustable battery bays, which are automatically adjusted for Li-Ion, Ni-MH, NiCd and LiFePO4 batteries.
- This charger is only compatible with cylindrical Li-ion (3.7V output), Ni-MH/ Ni-Cd (1.2V) and LifePO4 (3.2V) batteries.
- Read the instruction carefully before charge. Do not charge batteries with a current higher than the recommended current (500mA/1000mA/2000mA).
- Use a 12V/2A adapter to charge batteries.
- Be aware, heat dissipation may cause burns.
- Remove the power cable when the charging is complete.
- Do not charge in extreme conditions (too high or too low temperature).
“Slots”, LCD and their function
- 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.
- 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.
