  • An update was made to this issue to make clear that the information about the resistance being higher on fully charged Lithium-ion packs was referencing A123 cells, NOT lithium polymer (LiPo) cells. The graph was also updated to show the pack consisted of A123 cells. Follow up testing is in progress on both LiPo cells and a different pack of A123 cells (Feb. 16, 2017). The results will appear in up coming Ampeers.

  • Changes to Keith Shaw's Talk to the EMFSO on best design practices. A must read!
    Keith's original article/talk, as posted on the EFO site for a long time, was split into four parts to be sure that it would fit on floppy disks.
    Patrick Surry has combined the original four parts into one. The whole article as one .pdf file.
    He also made a version to view on a phone, Kindle, etc. updated 11/01/12
