Liitokala Lii-S2 charger

First, the warning:

1. This charger can only be filled with cylindrical lithium ion battery (3.70V/3.85V), nickel hydrogen/nickel cadmium (1.2V), lithium iron phosphate battery (3.20V);

2. Before use, please refer to the manual carefully, pay attention to the recommended charging current of the rechargeable battery, do not exceed the recommended current charging;

3. Select to use 5VDC adapter, the output current should be no less than 2A (ampere);

4. The charger may be hot when charging, be careful not to burn it; please put it in a place where children can't reach it;

5. When you stop using it, please unplug the power supply and remove the battery;

6. Can only be used indoors at room temperature;

7. The test data of this product is for reference only. Please refer to professional instrument for actual situation.

Second, the charger specifications and features:

1. Adopt DC5.0V2A (nominal) input, two-slot independent charging and microcomputer management system;

2. The biggest highlight of this charger is that it can charge the battery without polarity!

3. The charging current has a total of three files 0.5A /1.0A/2.0A, the default is 0.5A charging, you can press the corresponding button to select the charging current;

4. When charging, the LCD can display the channel CH and the charging current, voltage, time, capacity and battery type of the channel Li-Fe3.20V/

Li-ion 3.70V/Li-ion 3.85V (IMR); the charging current of the two slots does not exceed 2A in total, that is, when one slot is charged with 2A current, and then the battery is charged in another slot, the front 2A current will fall back. Charging to 1A current; when the battery is full, the LCD will display FULL;

5. It can automatically identify lithium battery (Li-Ion 3.70V) battery and nickel-hydrogen (Ni-MH) battery, manually select lithium iron phosphate battery (3.20V) and

  Li-Ion 3.80V battery (IMR);

6. There is 0 V voltage activation function, 1.65-2.20V can not be charged (but there will be active current turbulence type charging).

7. Multiple safety protection functions such as overcharge, over discharge, short circuit, etc. can automatically and automatically identify bad batteries;

8. Charging mode: constant current and constant voltage.

Third, the button and display:

1. Button (Mode): 2 buttons Each button controls a slot. Within 5 seconds after power is put into the battery, click the Mode button of the corresponding slot to select the type of rechargeable battery. Press and hold the Mode button to select the charging current. After the battery type (such as 3.20V/ 3.80V) and the charging current are required, the operation is stopped, and after 5 seconds, the charging state is entered; during the charging process, the battery capacity/charging time/battery voltage can be inquired by clicking the button;

2. LCD: After the charger is connected to the power supply, the LCD display will display for about 2 seconds and then display null. When the battery is detected, the LCD displays the corresponding slot number, battery voltage and current, and the battery type symbol flashes (NiMH/ Nickel-cadmium 1.2V battery-free type symbol flashing), after 5 seconds, enter the default identification to charge the battery. At this time, the charging display “V” symbol flashes to indicate that charging is in progress, and FULL is displayed when charging is completed;

*LCD display reference picture is as follows:
