One battery world.
Six open-source projects, six islands, one archipelago. Learn the cell, keep the data honest, design the pack, and watch the supply chain move — under your own sky.
Great batteries begin with first principles.
Interactive labs, tested Python models, and executable notebooks — every assumption stated, every unit checked.
