Capacity for runtime planning
The 5000mAh nominal capacity gives pack designers a defined starting point for energy and runtime calculations. Final runtime depends on pack configuration, load, and operating conditions.

Current and C-rate values should be confirmed for the intended pack configuration, thermal design, protection system, and operating conditions.
Three product characteristics help buyers decide whether this cell fits a demanding design review: capacity, current delivery, and resistance.
The 5000mAh nominal capacity gives pack designers a defined starting point for energy and runtime calculations. Final runtime depends on pack configuration, load, and operating conditions.
The listed 25A / 5C maximum continuous discharge and 40A / 8C peak discharge support evaluation of short-duration and sustained current requirements.
Internal resistance is listed at ≤14mΩ. Use this value in pack-level electrical and thermal reviews, alongside the selected interconnects, protection system, and enclosure.
Choose the cell when its current, size, capacity, and temperature parameters align with the complete system design.
Procurement teams should qualify operating limits and documentation alongside electrical performance. The product information mentions UN38.3 and UL safety, while the temperature and cycle-life values provide practical checkpoints for design review.
Charge at 0°C to 45°C and discharge at -20°C to 60°C according to the listed specifications.
The listed storage temperature range is -20°C to 45°C.
Cycle life is listed as ≥500 cycles for purchasing and service-life evaluation.
Ask for the applicable UN38.3 and UL documentation during the quote and shipment-planning conversation.
Share required quantity, target application, pack configuration, delivery destination, and documentation needs. The product team can then help organize pricing and the next purchasing step for standard supply, bulk orders, or pack-assembly discussions.
