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

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. - This may be useful copied to the cubesat reflector.
