I ended up ordering 32 of the 3.2v 280ah LiFePo4's you have here. Looking forward to putting them together later this winter. I like the ideas you and Dan have been bandying about. If you have one... can you send a picture of your set up once the busbars and BMW wires are connected. In particular would like to see a close up of how you "insulated" the terminals. I don't have a 3D printer but could get someone to do it... or I could probably figure out a different way to insulate with plastic sheaves and washers, if I understand correctly what you are trying to accomplish with 3D printing. Thanks.
