4-slots independent charging and independent management system, Micro USB DC 5V/2A input.
With battery polarity auto-detection function(any polarity).
Selective 0.5A/1A/2A charging currents for Lithium batteries by long press the current on. The defaulted current is 0.5A.
Built-in digital display screen shows the real-time charging status of channel no. (CH), voltage, current, time, capacity and battery type of Li-Fe 3.20V / Li-ion 3.70V /Li-ion 3.85V (IMR); When two channels charging, total current will be no more than 2A( when only 1pcs battery inserted, the charging current will be 2A, after the second battery inserted, the current will be automatically lowered to 1A; when charging finish, it shows "FULL".
Identify Li-Ion and Ni-MH battery automatically; Select manually by short-press the mode on for IMR battery(3.85V Li-ion )and LiFePO4 battery(3.2V). Will not charge batteries with 0.0≤U<0.2V for NiMH/Cd and 1.65≤U<2.2V for Li-Ion.
Charger specifications and functions:
1. Adopting DC5.0V2A (nominal) input, four slot independent charging and microcomputer management system;
The biggest highlight of this charger is that it can charge the battery regardless of polarity!
3. There are three levels of charging current: 0.5A/1.0A/2.0A. The default charging current is 0.5A, and you can long press the corresponding on to select the charging current;
During charging, the LCD can display channel CH and its charging current, voltage, time, capacity, and battery type Li-Fe3.20V/
Li-ion 3.70V/Li-ion 3.85V (IMR)； The total charging current of the two slots does not exceed 2A, that is, when one slot is charged with 2A current and the battery is placed in the other slot for charging, the first 2A current will fall back to 1A current for charging; When the battery is fully charged, the LCD will display FULL;
5. It can automatically recognize lithium ion (Li Ion 3.70V) batteries and nickel hydrogen (Ni MH) batteries, and manually select lithium iron phosphate batteries (3.20V) and
Li Ion 3.80V battery (IMR);
6. It has a 0 V voltage activation function, 1.65-2.20V cannot be charged (but there will be activation current trickle charging).
7. It has multiple safety protection functions such as overcharging, overdischarging, short circuit, etc., and can intelligently and automatically identify faulty batteries;
8. Charging mode: constant current and constant voltage.
3、 on and Display:
1. on (Mode): Each on controls one slot. After powering on and inserting the battery, within 5 seconds, click the corresponding slot's Mode on to select the charging battery type. Long press the Mode on to select the charging current. When the desired charging battery type (such as 3.20V/3.80V) and charging current are selected, stop the operation and enter the charging state after 5 seconds; During the charging process, you can click the on to query the battery capacity/charging time/battery voltage;
2. LCD: After connecting the charger to the power supply, The LCD monitor displays fully for about 2 seconds and then shows null When a battery is detected, the LCD displays the corresponding slot number, battery voltage, and current, while the battery type symbol flashes (nickel hydrogen/nickel cadmium 1.2V without battery type symbol flashing). After 5 seconds, it enters the default recognition to charge the battery. At this time, the charging display "V" symbol flashes to indicate that charging is in progress, and when charging is completed, it displays FULL;
*The LCD display reference diagram is as follows:
