Hello members, I would like to know if it is possible to connect a solar pane to feed the battery of the board. the battery will be a 3.7V Li. ---

Are you powering on the board by usb 5V now? ---

I am powering yes, but it is for a further moment. it would have a lipo battery 3.7 V and 650mhA. The solar panel would be for charging the battery. Another option is to use the solar panel to power the board directly with a voltage converter. ---

Where is your 3.7v feeding to the mangoh board? ---

if I use the Lipo battery, it would come from this one. If I use the solar panel directly, then from the solar panel. ---

I saw in the schematic, there is battery input port ---

so, a solar panel would be possible, right? ---

I think you need to make some test on that battery port > **[mangOH\_Yellow\_Hardware\_Architecture\_Guide.pdf](https://mangoh.io/uploaded-documents/Reference/mangOH%20Yellow/Discover/HW%20Reference%20Manual/mangOH_Yellow_Hardware_Architecture_Guide.pdf)** > > 1011.50 KB ---

Hello again, I’ve been looking around, and I need a battery that will last me two years, sending geolocation, temperature, humidity and acceleration data every 15 minutes. How much mhA of battery would I need to last two years? ---

I think you need to make some test and measure the current
