LINKDATA INR21700S-50T
LINKDATA 21700 cylindrical rechargeable lithium-ion cell. Typical capacity: 5.0Ah; minimum capacity: 4.9Ah. Continuous discharge: 50A without an 80°C temperature cutoff, or 90A with an 80°C temperature cutoff. Capacity retention is at least 80% after 1000 cycles at 25±2°C with 5A charge and 5A discharge. Cycle test: charge to 4.2V, hold at constant voltage until current reaches 0.02C, discharge to 2.5V, and rest for 30 minutes. Diameter: 21.35±0.15mm; height: 70.7±0.2mm, including the sleeve; weight: 67.0±1.5g. The cathode chemistry is not specified.
