Description
3.7V 4000mAh 18650 Li Ion Battery Pack
Product Features

Rechargeable Lithium Ion (Li-ion) cells feature a negative electrode (anode) made from lithium compounds. Lithium's high reactivity and lightweight properties compared to NiMH metal alloys result in superior gravimetric energy densities. These cells maintain performance during 12-month storage without maintenance and offer an expected cycle life exceeding 1000 cycles.

Key Advantages
  • Higher voltage and capacity
  • Superior specific energy density
  • Long cycle life (1000+ cycles)
  • Safe operation with no memory effect
  • Low self-discharge (<3% monthly)
  • Fast charging capability
  • Excellent discharge performance across temperature ranges
  • Environmentally friendly with no toxic materials
  • 12-month storage capability without maintenance
