1. New touch control function; 2. Four slots work independently individually; 3. With auto automatic and manual two working methods; (the default system is auto auto, which distributes power automatically) 4. Various optional charging currents: 250ma / 500mA / 1000mA / 1500ma / 2000ma / 2500ma / 3000ma; 5. Three-speed discharge current: 250ma / 500mA / 750ma; 6. This product uses an independent LCD display containing the battery type (li-ion-3.7v, ni-mh1.2v), working mode (auto / manual manual), battery channel (CH1 - CH4), operating mode (charge mode / discharge mode / test detection mode / Repair repair mode), charge and discharge level (mAh), charge and discharge time (h), charge and discharge current (ma ), battery voltage (v), battery charge percentage%, battery internal resistance (m), Parameters such as temperature , comprehensive and clear; 7 . In charge mode, 4 channels work independently, each channel can choose different charging current and detect charging capacity; 8.discharge mode, 4 channels work independently, each channel can choose discharge current different and detect the discharge capacity; 9.test mode, the normal battery capacity detection process contains three steps (1 charge, 2 discharge, 3 recharge), to detect the process battery capacity; 10. Different channels can work with different modes (Charge, Discharge and test, Repair four modes); Independent setting of charge/discharge capacity detection/normal capacity detection function; 11. Multiple protection functions: overcharge and discharge, short circuit, temperature, 0v voltage activation function, (-V and 0V), 1.65v-2.2v can not charge function, intelligent identification of the bad battery and reverse battery detection
