คําอธิบายสินค้า
EVE INR21700/50PL 5000mAh 50A Tabless High-Drain Lithium-ion Cell for Advanced Power Tools
Product Overview

The EVE INR21700/50PL is a cutting-edge, industrial-grade 21700 cylindrical rechargeable lithium-ion cell designed and manufactured by EVE Energy Co., Ltd. for high-performance civil hardware networks. Utilizing advanced tabless (全极耳) structural layout, this cell achieves an ultra-low ex-factory AC internal resistance of ≤ 5mΩ. This design optimizes electron pathways and dramatically suppresses heat build-up under extreme thermal and mechanical strain.

Featuring a robust 3.60V nominal voltage and massive 5000mAh standard capacity, the 50PL delivers an astonishing 50A (10C) maximum continuous discharge current (with recommended 75°C temperature cut-off and 80°C maximum hardware protection threshold). It supports ultra-fast charging capabilities up to 10A (2.0C) and offers resilient power delivery across tough professional operational profiles. It stands as a premium power solution for heavy-duty electric power tools, professional garden machinery, and industrial automation electronics.

Key Performance & Advantages
  • Advanced Tabless Technology: Features an ultra-low internal resistance profile (≤ 5mΩ), lowering energy loss and minimizing surface temperature spikes during high-rate discharge runs.
  • High Discharge Rate Capabilities: Retains a stable discharge plateau across high-current outputs at 25°C, providing outstanding rate efficiency (95% relative capacity at 30A; over 95% at 40A compared to a 10A baseline).
  • Extended Industrial Cycle Life: Engineered to survive demanding workloads, maintaining ≥ 60% of its initial capacity after 400 aggressive cycles under a high-stress 10A (2C) charge and 40A (8C) discharge profile.
  • Solid Low-Temperature Capacity: Delivers excellent efficiency across cold-weather job sites, retaining ≥ 60% relative capacity at -20°C, ≥ 75% at -10°C, and 80% at 0°C under a 12.5A (2.5C) heavy discharge load.
  • Excellent Storage & Recovery: Retains strong chemical stability, achieving a capacity recovery of ≥ 90% of its standard discharge capacity after being stored at a fully charged state at 60°C for 30 consecutive days.
  • Verified Structural Safety Compliance: Successfully fulfills rigorous environmental and safety test matrixes without fire or explosion risks, including 1.0m concrete drop tests, UN38.3 vibration and low pressure tests, and comprehensive safety validations.
Core Applications
  • Industrial & Professional Power Tools: High-torque impact drivers, heavy-duty hammer drills, cordless circular saws, and industrial angle grinders.
  • Commercial Outdoor Garden Equipment: Professional cordless lawnmowers, heavy-duty chainsaws, weed trimmers, and high-velocity leaf blowers.
  • High-Suction Cleaning Networks: Cordless stick vacuums, heavy-duty commercial carpet cleaners, and premium smart robotic floor sweepers.
  • Custom Battery Packs & Robotics: High-output custom multi-series packs for Automated Guided Vehicles (AGVs), warehouse robotics, and light e-mobility infrastructure.
Critical Safety Instructions & Usage Notice
  • System Protection Mandate: The cell must be assembled with a dedicated Battery Management System (BMS) or safety circuit board. The host system must monitor each cell block voltage independently to prevent imbalances.
  • Discharge Cut-off Guard: Never allow the cell voltage to drop below the 2.50V safety limit. System protection must automatically trip when reaching 2.50V to avoid catastrophic over-discharge.
  • Charging Constraints: Do not exceed the maximum charge voltage of 4.20±0.05V or maximum current of 10.0A. Inverse or reverse charging is strictly prohibited as it can permanently damage the cell.
  • Physical Pack Assembly Handling: Direct soldering onto the cell body is strictly prohibited; cells must be connected using spot-welded nickel strips onto the terminal caps to prevent thermal separator damage.
  • Handling & Disassembly Precautions: Do not dismantle, puncture, crush, or incinerate the cell. If electrolyte leakage is detected or a pungent odor is present, discard the cell immediately.
  • Long-Term Storage Management: For storage extending beyond 3 months, it is strongly recommended to store cells at a low-temperature range (0 ~ 25°C) in a dry, non-corrosive environment.

Questa batteria con 5000mAh, buona scarica da 80A, mi piace questa batteria
The packaging was good, nothing was damaged. I waited for over a month to receive the goods, and the battery cells are good.
