High-power cylindrical 21700 lithium-ion cell requiring an external pack, BMS, thermal design and protection system
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.
9 known suppliers in this product family.
Rechargeable cells, smart packs and custom battery suppliers relevant to mobile and field robots. The list is bounded to the current RCI manufacturer-directory universe and separates exact-model audited suppliers from confirmed product-line suppliers.

1 bounded physical-evidence record.
Publisher independence, identity precision and measurement scope vary by row. Results remain bounded by the disclosed specimen, setup, workload and metric; an inconclusive mapping is evidence associated with the catalog model, not verification of a manufacturer claim.

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.
