I have a Seeduino Stalker (It's an arduino like system) http://wiki.seeedstudio.com/wiki/Seeedu ... _Solar_Kit connected to a Raspberry pi by radio nrf24L01+
I monitor the swimming pool temperature

Everything works fine
3 days ago I noticed condensation under the transparent cover. I thought rain water has come inside. Clear liquid (I though water) was at the bottom of the box. I opened, cleaned and dryed.
But the following morning condensation again.
Plus the system has stopped 11pm same day just after daylight went off and restarted the following morning when daylight was back.
So I think the battery is dead and the liquid was not water but electrolyte. Do you think this is possible?
It seems possible according wikipedia specially the battery is exposed to high temperature: when the sun is there it can reach more than 60°C inside the enclosure. See here http://gcolin.hd.free.fr/Gujan/temperat ... /page.html(live graph)
But these last 2 days the system is up again with no problem....
Ok the question is more related to lipo battery than to Raspberry Pi but there is so much maker knowledge here
Any experience feedback from anybody?
