today’s fun permacomputing project: rebuilding the battery pack for the nec mobilepro 790
it turns out that, thanks to a single post dug out of the hpcfactor.com forums, the mobilepro 7xx uses a standard 18650 lithium-ion cell.
they turned out to be surprisingly expensive online, so i checked locally and found someone who had harvested dozens of the cells out of his dead ebike battery. for $2 a cell, i bought half a dozen and can’t wait to repack the battery case.
