Solar charger for 1S Li-ion batteries SDBK03TA CN3158 5V

Product detailed description

This model is designed for charging lithium batteries using constant current/constant voltage (CC/CV). It does not have overcurrent and short circuit protection, not recommended for use with a battery that does not have integrated protection.

Function:

This module uses the CN3158 charge controller

• Constant current and constant voltage control for charging the connected lithium battery,
• Solar Maximum Power Point Tracking (MPPT)
• Surge protection - the module will safely charge the battery

The module includes two LEDs. LED marked CR indicates charging. LED marked OK indicates complete charge.

Maximum Power Point Tracking (MPPT) of the solar cell ensures that the PV cell always puts out maximum power to fully utilize the sun's energy when the light intensity changes. In general, the MPPT function must be implemented with the switch mode of the DC-DC converter to maximize the output power of the output voltage and charging current.

Specifications:

The maximum current is set by resistor R1:

Notes:

• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
• You must be careful when connecting two cells in parallel. Both cells must have the same voltage. If one cell has a lower voltage, it would discharge to the lowest possible discharge limit. If possible, both cells should have the same voltage. In this case, the tension will be balanced. If the voltage of the two cells is very different, the cell may overheat or worse. When charging two cells in parallel to this module, the charging current of each cell is half of the total charging current of the module, i.e. each cell has the same voltage level.
