Solar Charger

This is a supper mini Solar Lipo charger based on the CN3065 – a single lithium battery charge management chip. This Solar charger provides you with the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargeable LiPo battery. Set-up is easy as well, just plug your solar panel into one side of the Solar charger and your battery into the other and you are good to start charging! The output of the Solar Charger is intended to charge a single polymer lithium-ion cell. The load should be connected in parallel with the battery. By default, the Solar charge comes set to a maximum charge current of 500mA with a maximum recommended input of 6V (minimum 4.4V). It’s recommended that batteries not be charged at greater than their capacity rating.



Solar panel input: 4.4-6V Max charge current: 500Ma Interface: 2-pin JST connectors(or PH2.0) Short circuit protection Continuous Charge Current Up to 500mA Battery status indication ( Red : Charging , Green: Charged ) Micro-USB Connector


Input voltage: select the corresponding module according to the nominal voltage of the solar panel (6V/9V/12V) Output voltage: nominal 3.7V full charge voltage 4.2V lithium battery Interface: 2-pin JST connectors (or PH2.0) Solar panel maximum power point tracking Complete charge management for single-cell lithium batteries Charging current up to 2A PWM switching frequency: 300KHz Charging voltage: 4.2V ± 1% Trickle charging of deeply discharged batteries Automatic recharge Charge status and charge end status indication Soft start Battery overvoltage protection Working environment temperature: -40 ° C to +85 ° C Size:45X20X9.5mm

5V 200mA 1W Solar Panel

Size :70*100MM Rated Voltage:5V Rated Current:200mA Max Power: 1W

1S Power display

How to use: Connect the positive and negative terminals of the display board to the positive and negative terminals of the battery under test, and the digital tube displays the real-time battery power Display battery parameters:   (Remarks: N is the number of battery cells) (The following data is a reference value, there will be an error range of about 2%, do not shoot if high accuracy is required)   The battery voltage is greater than N × 3.3V, with 1 grid lit The battery voltage is greater than N × 3.5V, with 2 grids on The battery voltage is greater than N × 3.7V, with 3 grids on The battery voltage is greater than N × 3.9V, with 4 grids on The battery voltage is less than N × 3.3V, and the four-segment display is all off, indicating that the battery is below 3.3V, and it is time to charge the battery.
