Liitokala Lii-100 smart battery charger 1.2V 3V 3.7V 4.25V 18650 26650/18350 16340 18500 AA AAA battery charger
1. Adopt Micro USB DC 5V input, single slot independent charging and management system 
2. Two charging current options are available (500mA /1000mA)
3. LED display charging status 25% 50% 75% 100%


 


   4. It can automatically identify Li-ion batteries and Ni-MH batteries and manually select Liepo4 batteries, (automatically identify 1.2V/3.7V batteries, manually select 3V/3.85V batteries)


 


   5. With 0V voltage activation function, 1.6-2.2V can not be charged


 


   6. There are overcharge and overdischarge, short circuit, intelligent identification of bad batteries and reverse battery detection protection.


 


   7. Charging mode, constant current and constant voltage


 


   8. Using DC input, the charger's working power supply is 5V-1A (Micro skewer)


 


   9. Type a: With standard 5V/1000 mA USB automatic identification output function,


 


      Type b: no USB output function


 


 


 


2. Description of buttons and functions


 


 


 


1. The charger has a button to select the charging current, the current button is easy to use. In any case, press and hold the selection button for 2 seconds to convert 500mA to 1000mA charging current, lightly press the selection button to change the rechargeable battery. When the rechargeable battery is selected (for example, 3V 3.85V), it will enter the charging state for 5 seconds.


 


 


 


2. When the charger is connected to a 5V power supply, all the LEDs of the charger will light up instantly. If the battery is not put in the charging operation, 500mA (LED) will display, and the LED will flash when a bad battery is detected.


 


 


 


 


 


 


 


3. When the charger is connected to the battery, it will automatically recognize the lithium battery 3.7V (Li-ion) and the nickel hydrogen 1.2V (Ni-MH),


 


 


 


Ferric phosphate 3.0V (Liepo4) and lithium battery 3.85V (Li-ion) need to be manually selected, and enter the charging state 5 seconds after charging is selected. When the system is charged by default, tap the select button to query the battery type and other functions cannot be changed
