Leaf battery busbar covers by Paul Kennett

Açıklama

If you are building a 48V DIY powerbank from used Nissan Leaf battery modules then you'll want some covers for the busbars for safety. This cover fits over a 20mm wide 2mm thick busbar (the same dimensions as the standard Gen1 busbars. It's 200mm long which is enough to cover a busbar that connects 6 modules in parallel. Two of them fit a 400mm busbar (that connects two groups of 6 modules). These are perect for a system with 7 groups in series of 6 modules in parallel. My print settings for a Bambu P1P: 0.28mm layer height with a 0.4mm nozzle in PETG (a bit for flex than PLA and slightly higher softening temp) no supports fuzzy skin perimeter is nice but not needed I printed 10 at-a-time on my 256 x 256mm print bed I needed 20 for my battery configuration. If you want to be really fancy you could print the covers in different colour for the positive (red), intermediate (white) and negative busbars (black). | Download free and paid 3D printable STL files
