[amsat-bb] Solar cell charging of Li ion.

[G0MRF@aol.com]

Hi.
 
This is a bit 'geeky' but may be useful to any cubesat builders reading the  
BB.
 
Freescale have a nice video on You Tube showing their new ultra low voltage  
DC-DC converters being used to charge a Lithium ion cell.
 
>From a single solar cell with an onload voltage of just 349mV they are  
charging a lithium ion battery at 3.82V at 63mA with about 83%  efficiency.

Sorry for the bandwidth. Geek time over.  -
