This derating is actually really easy to implement: a standard lithium ion cell is actually fully charged at 4.2V, but the battery management system will report it as fully charged once it reaches 4.15V or so.
- userbinator 1y agoFor aerospace they only go up to 4.05V, and the cells last tens of thousands of cycles with less than 10% capacity loss after a decade: https://www.nasa.gov/wp-content/uploads/2024/01/saft-ves16-cell-life-test-performance-update.pdf?emrc=65fc803378e2b https://www.nasa.gov/wp-content/uploads/2024/01/saft-ves16-c...
