Packaging Options:
26650 Case Kit (Case + Cap with Welded Tab + Top/Bottom Insulation Gaskets) – 100 sets/pack
Product Description:
26650 Cylindrical Battery Case & Shell Kit
Application:
Designed for the assembly of 26650 cylindrical lithium-ion batteries. The kit includes all necessary hardware (steel shell, safety cap, and insulation gaskets) for cell manufacturing.
Key Features:
* High-Quality Shell: The battery case is made from imported Japanese steel with nickel plating, offering superior strength and corrosion resistance.
* Safety Cap Assembly: Includes an explosion-proof cap with a built-in PTC thermistor and a pre-welded aluminum tab (15 mm x 6 mm x 0.15 mm), significantly simplifying the welding process.
* Complete Insulation: Supplied with both top and bottom insulation gaskets to ensure electrical isolation and safety within the battery pack.
