INTRODUCTION

The Epoch Batteries X4 Touch is a universal intelligent touch screen charging and discharging tester compatible with almost all rechargeable batteries on the market, thus eliminating the need to own several chargers. The X4 Touch automatically detects 3.7V Li-ion, Ni-MH and Ni-CD batteries and through manual selection is also capable of charging LiFePO4 and 3.8V Li-ion batteries. Intelligent circuitry selects the optimal charging mode (CC, CV and dV/dt) for a given battery and each of the X4 Touch’s four microcomputer- controlled charging slots then monitor and charge the battery independently. Furthermore, an integrated digital touch screen clearly displays all charging and discharging parameters and progress while an intelligent automatic power- off function terminates current when charging is completed.

FEATURES

• Microcomputer IC controls charging process

•  CC/CV/Trickle charging, to make sure the battery is full charged and won’t be over charged

• Four slots control independently by touch screen

• Mixed charging mode

• Color LCD instantly shows the charging process, battery voltage, current, time, capacity, charge curve, discharge curve and internal resistance

• Applicable batteries: Li-ion 3.7V, Li-ion 3.8V, LiFePO4, Ni-MH/CD cylindrical chargeable batteries (Diameter: below 32mm, height: 34-73mm)

• Input: AC100V-240V/ DC12V or DC12V 5A vehicle input

• Charging, Discharging, Capacity Test and Internal resistance

• Four types of charging current: 0.5A, 1.0A, 1.5A, 2.0A (According to different capacity); discharging current: 0.5A

• Reverse connection protection: When the battery is reversed, the corresponding battery icon shows “Battery Error”.

• Short circuit protection: When the battery is short circuit, the corresponding battery icon shows “Battery Error”.

• Activate automatically for Li-ion batteries with protection board, which are instantaneous short circuit.

• Intelligent temperature control:
  The built-in cooling fan will be automatically open, when the internal temperature of the machine rises to 60 degrees (Celsius) according to two temperature sensors. When the temperature drops to 40 degrees (Celsius), it stops automatically to ensure that the charger has a good working condition. Avoids high capacity batteries from overheating during the charge and discharge process, causing spontaneous combustion or ignition.

Note: After the charger is connected to the power supply, please do not test what the battery is charging in the charger in the slot, to avoid damaging the internal resistance test circuit caused by generated peak voltage of the bad contact. It is recommended to test the battery resistance after removing the battery. Test voltage range: 4.5VMAX, test internal resistance range: 0~255mΩ.

 OPERATION METHOD

1. The AC side of the power adapter plugs into the outlet, and the output side plugs into the charger.

   After booting, displays the following figure:

3. Access to the battery, if the users click the battery icon to enter the Settings Interface within 5 seconds, the charger will work as the setting parameters. Otherwise, it will automatically enter the default charging mode. As the following figure shows:

4. Switching Battery information
   After putting multiple batteries, click the battery icon which one the users want to check; the battery icon turns red, and all the information at the top of the main interface is the information of the selected slot.

5. Change settings:

If users want to change the setting, there are two ways:

1. When putting the battery, waiting for 8 seconds, click the battery icon. (Note: For Ni-MH batteries, charging current must be within 8 seconds. If there is no operation within 8 seconds, then charge in the default current and the current cannot be changed during charging.)
2. During the charging process, select the battery icon which need to change settings and click the battery icon again to enter the setting interface.

BATTERY ACTIVATION

For every installed battery, the X4 Touch will activate the battery by charging it. Activate automatically for Li-ion batteries with protection board, which are instantaneous short circuit. For the unprotected batteries’ voltage is above 0.2V, the activation methods are as follows:
A. Put the batteries in the X4 Touch. (During the process, it is normal that Li-ion batteries will be detected as Ni-MH batteries.)

B. When the voltage is above 2.75V, remove and reinstall the batteries and charge again.
Note: The X4 Touch is not recommended for use with over-discharged (zero volt) UNPROTECTED Li-ion batteries.

PRECAUTIONS

1. The X4 Touch is compatible with batteries of varying sizes, therefore when charging certain batteries, manually adjust of the battery’s position within the slot is recommended, as to ensure solid contact is made between both sides of the battery and the charging slot’s metal contact points.
2. The X4 Touch is restricted to charging 3.7V Li-ion, 3.8V Li-ion, LiFePO4, Ni-MH/Ni-Cd rechargeable batteries only. Never use the X4 Touch with other types of batteries as this could result in battery explosion, cracking or leaking, causing property damage or personal injury.
3. The X4 Touch should only be used indoors and it cannot be used or stored in the water, high humidity, direct sunlight and low or high ambient temperatures.
4. Do not disassemble or modify the charger.
5. Children under the age of 18 should be supervised by an adult when using the X4 Touch.
6. The X4 Touch’s safe operating temperature is between 0℃-40℃.
7. Please use the X4 Touch correctly according to this introduction manual to avoid product damage and personal injury. Any problem arising from improper use of the X4 Touch, our company will not bear any legal responsibility and economic disputes.
