Low-impedance high-power cylindrical cell requiring an external pack, BMS, fusing and thermal system
Power & Energy · 21700 lithium-ion cell
INR-21700-P50B
A 5 Ah high-power cell whose 60 A headline remains a cell-level claim, not a protected robot-pack output rating.
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.

| Independent direct-component measurementindependent_physical_evidence | Capacity, energy, temperature and cycle-life traces published through 2,000 cyclesProfessional cycler, four-wire welded connection and 25 ±0.5 °C chamber; sample-level test. | inconclusiveThe record establishes bounded physical evidence for the named model, but the experiment does not reproduce the catalogued claim metric and conditions; the claim remains inconclusive. | Molicel P50B variable charge-rate cycle life test ↗Equipment, test settings and capacity/cycle charts Checked 2026-08-26 |

Known limits
What this record does not prove.
- This is a cell, not a battery pack.
- The 60 A headline requires the datasheet temperature and cutoff conditions.
- Cell reports do not replace pack-level safety, transport and integration evidence.
