Step one is requirements: clarify the device's voltage platform, capacity, envelope, connector, and environment—these directly drive cell selection and structure.
Step two is design: combine BMS, mechanicals, and thermal management into a buildable PACK plan, and confirm safety and certification needs with the customer.
Step three is prototyping and validation: verify performance via charge/discharge, temperature rise, and vibration tests, iterate, then ramp from small batch to volume. With its own factory, Sanfo offers controllable assurance on delivery pace and quality.
