Questions
How big is the Battery node PCB?
It measures 44.2 × 66.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Battery node use?
223 parts, built around the ESP32-H2-MINI-1-H2S, TCAN334D, ISO7041FDBQ and MIE1W0505BGLVH-3R-Z. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Battery node KiCad files?
From the ColtonTshudy/battery-node repository on GitHub, at the commit this page was made from: the board is bms-logic/battery-node.kicad_pcb and its schematic bms-logic/afe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Battery node design in my own project?
Its repository states no licence, so its author keeps all rights: ask ColtonTshudy before reusing the design.
