With the LUC V4 charger, you would no longer warry about the low battery problem.

NOTE:

Use special caution when working with Li-ion cells: they are very sensitive and may explode or burn if mis-handled.

Be sure that you have certain understanding about Li-Ion rechargeable batteries in charging, discharging and assembly before use.

Always charge in/on a fire-proof surface.

Use rechargeable batteries or with PCB batteries. Other types of batteries may cause personal injury.

Do NOT leave batteries charging unattended/overnight!

Features:

1. Charging input: Pressing the rectangle button can change the charging modes(0.5A/1A/2A) and charge different size 3.6V/3.7V Li-ion batteries.

2. High compatibility: with DC 5V 1A USB socket and DC5V 0.5A USB socket, this charger can work with most electronic products like cellphone, ecigarette, IMR series batteries.The DC5V 1A USB output connector are compatible with most portable consumer electronics. And the DC 5V 0.5A/1A can charge 4pcs : 10440/14500/14650/16340/16650/17650/17670/17350/18490/18500/18650/22650, 2A can charge 2pcs : 25500 and 26650 batteries.

3. Low power alarming: when discharging consumer electronics, the transparent button will be flashing in blue while the power of battery is lower than 15%, it means battery needs to be charged.

4. Built-in reverse polarity protection: While the charger is connected, each charging channel has reverse polarity protection, the charging light is still green and prevent from any short circuit.

5. Zero voltage activation function: when charger is standby, place over-discharging batteries (battery voltage is under 2V) to charging channel correctly, battery zero voltage activation starts, since battery over-discharging times, capacity and over-discharging degree is different, so the activation time will be different, and red light will turn on after battery activation.

6. Over-charging protection & automatically monitor charging: Once the external power is connected with LUC V4 charger, charger will stop charging when batteries are full; if batteries were not taken off and the battery voltage will be lower than 3.9V because of many factors, charger will charge batteries automatically again. charger will start to charging if putting lower 4.18V batteries into LUC V4 charger.

7. USB output: Once connected to USB , Pressing the rectangle button for over 1 second,then it will get start to charging. The USB function will be closed in 30 seconds without connecting power. DC5V 1A USB output connector are compatible with most portable consumer electronics.
