Update of /cvsroot/firebug/firebug/doc In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv15938 Added Files: battery_test.txt Log Message: Documentation regarding the Li-Ion battery performance test --- NEW FILE: battery_test.txt --- 7/16/04 Today I ran a test to see how long a recharged Li-Ion battery could run a mote. Since we noticed a significant number of battery failures after connecting the GPS antennas to the motes, I specifically wanted to see how long these Li-Ion batteries could last while the motes operated with the GPS antennas. Since we currently do not have a means of connecting the Li-Ion battery directly to the mote, I had to use a breadboard to help establish the power connection. Using a molex connector that I had created before, I connected it to the mote and then to the breadboard. Then, the battery was connected to the breadboard. The battery I used started at 4V, which is what I had charged it to earlier. The battery ended up running the mote for 5 hours before it started to give bad data. Surprisingly, when this the mote was no longer producing valid data, the Li-Ion battery was still at 3.5V. |
