Features:
XTAR WP2Ⅱcharger is apply to charging for two 14500/ 14650/ 17670/ 18500/ 18650/ 18700 3.7V Li-ion battery simultaneously but independently, it can charge for 10440/16340 when use 2pcs spacers. It is designed algorithm (TC.CC.CV) charging method which can monitor the battery's status real time and control charging safe automatically.
WP2Ⅱdesigned with USB output function, use fully charged battery can supply electricity to those devices power below 5.0V/500mA.
WP2ⅡCharger adopts reverse-polarity protection circuit board and over/under voltage disconnecting technology, can prevent the possibility like sundries, wrong polarity and misoperation caused short circuit.
WP2Ⅱbuilt battery over discharging activating function, it can repair varying degrees discharged battery and then charging automatically, it is your first choice safer and reliable Li-ion battery charger.

Usage and LED Indicator Instruction:
1."0" Gear: USB 5.0V/500mA voltage output.
"1" Gear: Charging current 500mA
"2" Gear: Charging current 1000mA
2. The SCM will start to self check when connected the external power, Channel 1 and Channel 2 enter into charging standby status and indicator turned green from red. It starts to charge if the connection detected last more than 5 seconds normally and indicator turned red. When the batteries are full charged and indicator turned green, then charging complete. Bad contact, wrong battery polarity, no charging current or battery activating status green indicator.
3. When battery laid into channel 1, gear shifted to "0" . If external power connected and the red indicator flashing, the USB interface no output voltage. When the external power disconnected and channel 1' s indicator extinguished but USB interface indicator turned red, USB output is processing. If the battery pulled out, USB output stopped and no indicator.
4. When charger is standby, both the indicator of channel 1 and 2 turned green if we short out them, but it is no harm to charger for WP2Ⅱhas short circuit protection function.
5. WP2Ⅱwill restart charging when detected full charged battery voltage lowered than 3.9V if the external power normally connected.
6. USB output protection function will be activated if the battery's voltage in channel 1 is lower than rated value. Then the indicator extinguished and no output.
7. WP2Ⅱcan apply to charging for two 14500/ 14650/ 14650/ 17670/ 18500/ 18650/ 18700 3.7V Li-ion battery, also for 10440/16340 when use 2pcs spacers.
