The circuit board has no over charge and over discharge protection

The battery must be equipped with a protection board, otherwise it will be overcharged or discharged and damage the battery

Parameters:

Compatible battery voltage: 3.7v-24v

Solar panel input voltage: battery voltage X1.5 = solar panel voltage

Output voltage: battery voltage = output voltage

Maximum input current: < 3A

Maximum output current: < 1A

Control mode: light control (after connecting the solar panel, the light is not on during the day. It will be on automatically in the dark)

Size: 25 * 15mm

It is widely used in solar lawn lamp, solar column lamp, solar landscape decorative lamp, solar wall lamp and other low-power solar products control

Note:

1. The output terminal of this circuit board cannot be connected with various types of boost circuits;

2. Do not use LED lamp beads directly, but need to be connected with step-down drive (or series suitable resistance current limiting);

3.The battery must be equipped with a protective board, otherwise it will be damaged due to overcharge or over discharge

4.Please connect the battery first, then the LED lamp, and finally the solar panel
