Lii-s4

Automatic polarity detection charger

 This charger is designed for portable, flexible and multi-type batteries. It can automatically detect battery polarity, battery types and charge the battery under the selected charging current. Built-in digital tube indicator for real-time display of charging status
  

Precautionary measures:

Features:

1. Four slots independent charging and MCU control system, micro USB DC 5V input Min.2A

2. The brightest point of this charger with automatic battery polarity detection function (Any polarity)

3. Selective charging current 0.5A / 1A / 2A for lithium batteries by long pressing the current button. The default current is 0.5a

4. The built-in digital tube indicator shows the real-time charging status of channel No. (CH), voltage, current, time capacity and type of battery Li-Fe 3.20 V / Li-ion 3.70 V / Li-ion 3.85 V (IMR); when there are two charging channels, the total current will be no more than 2A (when you insert only 1 piece of battery, the charging current will be 2A, after the second battery is inserted, the current will be automatically reduced to 1A; when charging is complete, it shows "full";

5. Automatically detect lithium-ion and ni-mh battery; Manually select by briefly pressing the mode button for Battery IMR (3.85 V li-ion) and Battery LiFePO4 (3.2 V )

6. Activation function for battery 0 in PCM protection.

7. Will not charge batteries with 0.0 ≤U <0.2 V for NiMH / Cd and 1.65 ≤U <2.2 V for li-ion

8. Various functions of protection against overcharging, overdischarge, short circuit and can automatically detect a broken / faulty battery (will not charge bad batteries);

9. Charging at constant voltage and current

Office Instructions:

1. buttons: there is a “mode” button for each channel separately, choosing battery types, charging current

And charging status tracking

U long press the “mode” button for 3 seconds to change the charging current for lithium batteries, you can change the charging current at any time

U Short press the “Mode” button to change the charging types of lithium batteries. If there is no setting, it will default to 1.2 in Ni-MH or 3.7 in lithium-ion battery automatically. It is necessary to change the mode for 3.85 V li-ion and 3.2 V LiFePO4 batteries

U he starts to charge the battery 5 seconds after your settings

2.Charge display: Connect the 5V input port with a USB cable, a digital indicator shows

All information for 2 S and "null" if battery is not inserted; after it detects with the battery inserted, showing the channel no, the battery voltage and current while the battery type symbol is flashing (there will not be a battery type symbol flashing function for NiMH / rechargeable batteries); Then in 5S, it will start charging with a “V” flashing (charging starts).When the battery is fully charged, it shows “full”
