Hi guys,
I am new to this board as well as to working with electronics. So please excuse if this is a stupid question and / or has been answered before. I have been searching here and via Google but I am still not sure.
I do have a small vario (a small instrument that beeps when raised or lowered by checking the air pressure) that has a 750mAh battery and lasts around 10 hours in normal operation. It has a 5V USB slot to charge it.
Since the instrument is - when used - at clear sunlight most of the time, I thought about adding a small solar panel to increase running time ...
The battery is a LiPo 3,7V 750mAh, protected against over- and undervoltage.
I have found a solar panel that would perfectly in size:

Now the question is: will it work when I connect the wires of the panel directly to the battery?
Or would that be not too good for the battery (I have read about LiPo being a little touchy)?
How about connecting it to the USB port instead?
Any help is greatly appreciated.
Dieter
