SeeedStudio confirmed that you can find the connector for the solar panel here: Seeedstudio JST 2 Pin Power Connector
Also, the behaviour you describe seems strange. I can still get power at the 5V pin on the Arduino when connected to the USB. As a matter of facts, I get more power when connected to the USB since I can get more current.
Maybe you would like to submit a picture of your setup in order to better illustrate your problem.
If you send us a message to the support centre we can offer you an exchange (but it will indeed take approximately two weeks before the chargers arrive to our warehouse)
I’m glad to see that the operation went well and that you successfully replaced the diode.
Indeed, the charging/charged LEDs seem to be controlled by the current flow going out of the power supply. That is why they will show as charging if the power supply is plugged and the 5VDC is powering a load.
Also, thank you for sharing the results of your rather thorough and detailed testing, It is really appreciated.
The status will show charging as long as there is power being drawn from the supply (the solar panel in this case).
SeeedStudio should be providing further details on the datasheet information soon.
That could definitely be done by connecting the output battery output to an analog pin and read the values from it. This is possible since the battery output does not exceed 5V DC.
Unless I am missing something. It seems to me that the current required is battery specific. I forwarded your question to SeeedStudio in order to see if they can provide a better answer.
We will inquire on the new Solar charger and let you know of the new specifications shortly.
Thank you for keeping a very attentive eye on this product.
