Features:
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 button. 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 button 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.
Multiple safety protection functions of over-charging, over-discharge, short-circuited and can automatically Identify broken/defective battery(will not charge bad batteries). Charging under constant voltage and current.
