Key Advantages of 21700 Li-Ion Battery Packs

Superior Energy Density: The 21700 cells (21mm diameter, 70mm length) offer higher energy density compared to older 18650 cells, storing more power in a compact form. Ideal for space-constrained applications like e-bikes or portable power tools.
Extended Cycle Life: Advanced lithium-ion chemistry delivers 500-1000 charge cycles while retaining 80% capacity. Integrated BMS enhances longevity for long-term cost savings.
Integrated Safety Mechanisms: Battery Management System (BMS) safeguards against overcharge, over-discharge, short circuits, and thermal runaway. Premium cells include built-in safety vents and stable chemistry.
Broad Temperature Tolerance: Operates effectively from -20°C to 60°C, suitable for extreme environments. Features low self-discharge (1-2% monthly) for enhanced storage stability.
