Power & Energy · 21700 lithium-ion cell
INR-21700-P45B
A high-power cell record included to make the cell-versus-pack boundary explicit; it is not a drop-in robot battery.
Reported values, conditions attached.
Evidence state describes the claim—not the prestige of the company or document.

Known limits
What this record does not prove.
- This is a cell, not a protected pack.
- A robot battery requires cell matching, interconnect, BMS, fusing, enclosure, thermal design and pack-level certification.
