Assemble 18650, 21700, and 32700 cylindrical lithium batteries in series or parallel to meet your diverse DIY needs.

What Are Cylindrical Lithium Batteries?

Cylindrical lithium batteries are widely used due to their structural stability and performance advantages. Based on materials and casing types, they can be classified as follows:

  • Material Systems: LiFePO4, Lithium Cobalt Oxide, Lithium Manganese Oxide, and NMC.
  • Casing Types: Steel casing and polymer casing.

Among them, steel-cased LiFePO4 cylindrical batteries stand out as the mainstream choice due to:

  • High capacity and stable voltage output
  • Excellent charge-discharge cycle life
  • Wide operating temperature range and eco-friendly properties
  • Strong high-current discharge capability and superior safety

These features make them ideal for solar lights, lawn lights, backup power, power tools, and toy models.
