✅ Key Features & Advantages
Ultra-High Energy Density
Around 5× greater than lead-acid batteries, significantly cutting down e-bike weight. It means riders enjoy longer range, improved efficiency, and less power consumption on every journey.
Low Internal Resistance
Minimizes energy loss and heat generation. With less wasted energy, the battery runs cooler, lasts longer, and operates more efficiently.
High Discharge Current
Supports continuous 20A discharge (customizable to higher outputs). Perfect for demanding e-bike motors, steep climbs, or rapid acceleration without performance drops.
Comprehensive Safety Protection
Built-in BMS (Battery Management System) with overcharge, over-discharge, over-temperature, short-circuit, and reverse-polarity protection. Ensures maximum safety and reliability under all riding conditions.
Active Balancing Function
Prevents large voltage differences between cells. It guarantees stable performance, avoids sudden capacity loss, and extends overall battery lifespan.
Water & Dust Resistance
With waterproof materials, protection can reach IP65 rating. Ideal for outdoor, rainy, or dusty riding environments without performance compromise.
Long Cycle Life
Retains over 90% capacity even after one year of heavy use. Over 800–1000 charge cycles ensure long-term durability and reduced replacement costs.
Flexible Customization
Options for shapes (rectangular, cylindrical, triangular, arc), voltage, capacity, terminals, and OEM services (printing, labeling, packaging). Tailor-made to fit different e-bike brands and specific design requirements.
