Charging State and Battery Power Indication

• When the battery voltage reaches the next stage, one more bare will be added. No battery level icon will be displayed in the corresponding channel when the c harger is in one of the following c conditions:

VLEVP2

o no battery is placed in the c channel
o short circuit
○battery voltage < 1 .0V
○ battery is reversed or poorly connected

Charging LED Indication

status		LE D indic ation
charger self-check k		red (2 seconds)
charger s tand-by		green
battery	1.0 V - 2.0 V	red
ac tivated	< 1.0 V	green
charging		red
fully charged		green
U SB output	> 50 %	green
power	25 % - 50 %	red
indic ation	5 % - 25 %	red flas hing

• Due to different battery types, deviation between the value on the indicator and the battery's actual capacity exist. In addition, when the battery is c charging, the LCD displays the battery's c charging voltage (inc luding the voltage generated by the battery's internal resistance). When the battery is fully charged or not connected, the LCD displays the no-load voltage of the battery.

6. Operation

Before c harging your batteries, check that the battery types are c compatible with the VLEVP2. T hen, determine the suitable charge current and voltage settings for them.

Remark

Damage c can occur to the batteries and c harger if incompatible batteries are inserted, or if improper c harge current and voltage settings are selected.

Charging Batteries

1. Connect the supplied power adapter to the VLEVP2. The VLEVP2 performs a s elf-check, turning on two LEDs (red status indicator). During the s elf-check, the LCD displays the battery power indicator and the s elected voltage. After about two seconds, the two indicators turn green. The c harger then s witches to s tandby mode, no battery ic on will be displayed but the s elected voltage and default 0.25 A charge current.
2. Slide the voltage setting switch to choose the suitable voltage for your battery. The LCD will display the corresponding selected voltage. For example, if your battery's nominal voltage is 3.6V / 3.7V , then you should choose the 3.6V voltage.

VLEVP2

1. Choose the charge current that best suits your rechargeable Li-ion batteries:

0.25 A	suitable for 10440-18700 Li-ion batteries
0.5 A	suitable for 18700-26650 Li-ion batteries with capacity ≥ 2 500 mAh
1 A	suitable for Li-ion batteries with capacity ≥ 20 00 mAh, 1 A is the large charge current for fast charging

1. Press the CC button one or more times to change to a different charge current. Current arrangement is 0.25 A - 0.5 A - 1 A - 0.25 A.
2. During charging, double-press the current change button to check the selected voltage setting. The corresponding LCD displays the selected voltage. Choose the voltage setting suitable for your battery. After about 3 seconds, the LCD reverts to show the charge current, battery real-time voltage and charge status.
3. When the battery is fully charged, the VLEVP2 stops charging, and the status indicator turns green. The bars on the LCD will not be added again. It is recommended that you remove the batteries from the charger once charging has completed. If batteries are left in the charger after charging completes, the c harger will automatically restart the charging cycle when the voltage drops below 3 .9 V or 3.3 V, based on the c hosen voltage s etting.
4. During charging, press and hold the charge current setting button 1.5 seconds to switch the LCD on or off. The LCD is s switched on by default.

USB Power Output Mode

1. Ensure that the VLEVP2 is not connected to any powersource. Insert a battery ( ≥ 2000 mAh) into the CH1 s lot, being careful to insert it with the c correct polarity. P ress and hold the button for 1 .5 seconds to s tart the U SB power output function. After the LED indicator turns green, you can c onnect an external device to the USB port. In USB output mode, the LCD is invalid.
2. When finished using the USB power output, disconnected the external device, press and hold the button for 1.5 seconds to switch off the USB power output. After the status indicator extinguishes, remove the battery.
3. When battery capacity is above 50% , the LED indicator is green; when capacity is 25% to 50% , the LED indicator is red; when capacity is 5% to 25% , the LED indicator flashes red.
4. When the battery capacity is low than 5% , the USB power output switches off automatically.

VLEVP2

Remarks

• The VLEVP2 is only for use with 3.0V / 3.2V, 3.6V / 3.7V, 3.8V rechargeable Li-ion or LiFePO batteries. Charging other battery types may be hazardous, and can damage the batteries and c harger.
• The VLEVP2 has an integrated short-circuit protection to protect the charger if a short circuit occurs in a battery. Note that this short-circuit protection protects the charger and does not prevent batteries from short-circuiting internally.
• Keep the VLEVP2 away from water and excessive dust.
• Do not disassemble the VLEVP2 as damage may result.
• Do not use a damaged VLEVP2.

Tips

• The USB power output is only available when no external power source is connected and the battery is inserted into the CH1 slot.
• Press and hold the charge current setting to check the selected voltage. Suitable voltage is s strongly being recommended.
• Because of different battery types, capacities and over-charge depths, the battery revive time may vary. Heavily over-discharged batteries may not be able to be revived.
• Do not judge the battery is being charged or not when it is in the process of activation.
  To lengthen the over-discharged battery's lifespan, a 0.25 A charge current and suitable voltage are strongly being recommended.
• Specifications and features are subject to change. Please find the most recent description and specifications of the VLEVP2 on the Velleman website.

7. Cleaning and Maintenance

• T his device does not need any particular maintenance. However, oc casonally c lean it with a damp c loth to keep it like new.
