I doubt he'll end up reading this blog, but we can use this information to our advantage.Blakehttps://www.blogger.com/profile/07444504218981360701noreply@blogger.comtag:blogger.com,1999:blog-9076271022132673104.post-88404194583354952762009-09-14T16:33:23.500-07:002009-09-14T16:33:23.500-07:00To the 'homeboy' technical guy: I'm re...To the 'homeboy' technical guy: I'm really glad to see you were able to put a lot of your engineering skills from different disciplines to good use in one project. <br /><br />One thing I noted in your writeup under "Miscellaneous" is that Li-Ion batteries work well at low temperatures. I guess 'low' is relative, but compared to other batteries this is not true. Li-Ion batteries not only lose the majority of their capacity at a relatively high temperature (~freezing lets say), but their ability to supply surge current diminishes as well (with the advent of 'supercaps' this is less of a problem, as long as you account for it). From my experience these batteries are preferred in many military applications due to their capacity to weight ratio <i>despite</i> their poor performance at low temperatures.Unknownhttps://www.blogger.com/profile/10736117340645664764noreply@blogger.com
