DDNA-53-US-K — the cell's genomic identity
Every C4V cell carries a Digital DNA record — a self-contained record carried inside the QR code itself, readable offline by any phone camera with no app and no internet connection. It travels with the cell from factory gate to field.

BMS settings and system design
Every cell must be managed by a qualified battery management system (BMS). The key protection thresholds are listed below — full installation, operation, storage and transport guidelines are in the specification PDF.
| BMS function | Setting | Action |
|---|---|---|
| Stop charging | 4.1 V | Charging stops when cell voltage reaches 4.1 V |
| Overcharge protection | 4.25 V | Overcharge protection electronics must be in the BMS |
| Stop discharging | 3.0 V | Discharging stops when cell voltage reaches 3.0 V |
| Over-discharge protection | 2.7 V | Over-discharge protection electronics must be in the BMS |
| Over-current protection | 120 A | Overcurrent protection electronics must be in the BMS |
| Short-circuit protection | — | Short-circuit protection electronics must be in the BMS |
| Over-temperature protection | — | BMS stops charge and discharge when cell temperature is out of limits |
Installation & operation
Cells may be installed vertically (terminals up), horizontally, or on their side. Each cell must be monitored, controlled and protected by a qualified BMS whose design has been reviewed by the C4V gigafactory. Battery design must provide for heat dissipation, and modules must be waterproof and dustproof per UL and IEC standards. Operators should track each cell's internal resistance over its service life and retain BMS monitoring records — warranty claims require BMS diagnosis records.
Maintenance & storage
Never drain a cell into over-discharge — below 2.5 V the cell may be permanently damaged. Recharge stored cells periodically; recommended storage is −20 to 45 °C, with up to 6 months safe between −20 and 25 °C. For longer storage, recharge to around 50% SOC every three months. The BMS must prevent charging below the minimum charging temperature.
Transportation & safety
Lithium-ion cells are regulated as hazardous material under the U.S. DOT Hazardous Materials Regulations (49 C.F.R. Parts 171–180) and each carrier's own rules. Do not immerse cells in water, expose them to fire or temperatures outside the rated range, short-circuit terminals, reverse polarity, or overcharge. Secure cells to a solid platform, avoid plastic enclosures around electrical connections, and in case of electrolyte contact wash with plenty of water and seek medical assistance. Abuse testing may only be carried out by certified personnel in a professional laboratory.
Supply chain assurances
The genomic layer behind this specification
Digital DNA™ is C4V's battery-intelligence platform. It assigns every cell a measurable, traceable identity — chemistry, origin, manufacturing process, and electrochemical fingerprint — and carries that identity through the entire supply chain.
The DDNA record on this page is a live artefact of that platform. It can be scanned at goods receipt, embedded in compliance documentation, and queried by AI models to verify that what arrived is what was specified.
- Instant verification — scan the QR at any point in the supply chain.
- Permanent origin record — country, site, licensor and supplier recorded at manufacture.
- Machine-readable — JSON payload integrates with procurement and compliance systems.
