8-cell battery pack housing for 32113 cell size (A123 LiFePO4)

prusaprinters

<p>Modification of original by rounding corners (better for shrink-wrapping) and adjusted the cell radius and length to work for the much larger 32113 cell size made by A123 for automotive applications. Pack is for 8 cells. If wired in series you get 26.4v, or if wired 4s2p you get 13.2v. Either way it's about 100Wh. (Not a lot, but these cells have amazingly high C-rates and can be worked hard.)</p> <p>Future design tweaks may include recessed slots to make metal contact flush on outside of pack, and holes between cells for running balance wires neatly to their respective locations.</p> Category: Tool Holders & Boxes
