INR21700-B68U
Extended runtime without giving up high-current capability.
A 6,800 mAh 21700-format lithium-ion cell combining 340 Wh/kg gravimetric energy density with up to 54 A maximum continuous discharge for energy-sensitive, high-performance battery packs.
High energy density with practical 54 A performance in a standard 21700 format.
Choose the B68U when pack runtime and weight efficiency are the main priorities, but the application still needs strong continuous-current capability. Its 6.8 Ah capacity and 340 Wh/kg gravimetric energy density can reduce parallel cell count and pack mass compared with lower-capacity 21700 options, while the 54 A continuous discharge rating supports demanding propulsion, mobility and industrial loads.
High gravimetric energy density supports longer runtime without unnecessary pack weight.
More stored energy per cell can simplify pack architecture and reduce component count.
Strong continuous-current capability for performance-focused battery systems.
