Model: D4 Input voltage: DC 12V 1.0A Output voltage: 4.2V ± 1% / 3.7V ± 1% / 1.48v ± 1% Output current: 375ma * 4 / 750ma * 2 Size: 143mm * 99mm * 36mm Product features] Lithium battery charger is specially used for charging lithium-ion battery. Lithium ion battery has high requirements for charger and needs protection circuit, so lithium battery charger usually has high control precision and can charge lithium-ion battery with constant current and constant voltage. [charging process] When the power supply is not connected, the LED light on the circuit board is not on The power supply is connected to the circuit board, and the green LED is on continuously. At this time, the circuit board is waiting for the lithium battery to be placed After the lithium battery is put in, it starts to charge, and the LED turns orange When the lithium battery is fully charged, it stops charging and the LED turns orange After the lithium battery is fully charged, the battery is removed, the LED turns green, and the lithium battery is put in again for charging During charging, the charging percentage is displayed LED light: Keep green: waiting for battery Continuous yellow: charging Full or charged for 6 hours Flashing orange: warning message (output short circuit, reverse of positive and negative poles, abnormal temperature)
