Solar Cell for Pico Balloons. Polymer 4.8V 50mA

Ultra thin and light weight solar cells.
Nominal voltage 4.8V
Two of these are needed to power my Pico transmitter.
The power reserve from the super caps will be about 10 to 30 seconds when using these.

 
The weight for a single solar cell is 1.76gram.
 
These are great all year round solar cells and will work both for summer and winter flights with the Pico transmitter.
The 4.8V nominal Voltage will fully charge the super Capacitors on the Pico transmitter and give a greater power reserve compared to the 3.6V variant solar cells.
This is good for when the solar angle is low and the transmitter is spinning and the solar cells are temporarily pointed away from the sun.
