Description:
1. Limit large 5V 1.2A charging current, 5V output suitable for small current, automatic switching / normally open output, input and output display indicator, 3.7V lithium charging full 4.2V / suitable for 18650 polymer etc.
2. Smaller than 18650 battery cross-section charging module, but also with discharge, is an alternative to 4056 and other linear charging module. Comparison of 4056/4057 and other linear charging technology. This module charging temperature control is more excellent. Characterized by small size. Adopts Type C port for both input and output.
Instructions for use:
1. Automatically switch to output mode when there is no external input voltage, support small current, output 5V, output support about 450ma. If output 1A, the voltage will be around 4.9V-4.5V according to the power.
2. Automatic switching input and output, external voltage input when charging the battery, otherwise discharge, charging red light flashing, full of red light long light, discharge no load standby when the light does not light, with a load discharge when the blue light. Standby power consumption is about 0.8mA.
Precautions for use:
1. The first time to connect the battery to use the need to connect the power supply to activate the protection board
2. Input and output switching is not seamless, switching takes about 1-2S time.
Function Introduction:
1. When the charging current drops to 100mA after reaching the final float voltage, the charging cycle will be automatically terminated.
2. The charging current is limited to 1.2A, which can be stabilized above 1.1A under the condition of guaranteeing power supply and proper use.
3. When the battery voltage is lower than 2.9V, the battery will be pre-charged with 200mA current.
4. With protection board, over-voltage protection, over-discharge protection, over-current protection. Over-discharge protection value: 2.9V.
Attention:
1. Do not connect the battery in reverse, connecting reverse burns the board.
2. Connect the charging head before connecting the battery, test the module charging light is normal.
3. The line can not be too thin, otherwise the power supply current can not keep up, the line must be welded.
4. Batteries can be connected in parallel, not in series. Can only be 3.7V lithium batteries, full of 4.2V or so.
5. Module positioning is not used to do charging treasure, power is relatively small, limited to four or five watts. And does not come with charging protocol. May lead to some cell phone use will have problems, not recommended for modification of the charging treasure.
