18650 Battery Holder

An 18650 battery holder is a specially designed case or holder that securely accommodates 18650 lithium-ion batteries for powering devices. These holders provide a reliable way to connect batteries to circuits without soldering and ensure safety during use.

Key Features

• Material: Usually made of durable plastic (ABS or similar) with metal spring-loaded terminals for good electrical contact.
• Compatibility: Fits standard 18650 batteries (18mm diameter, 65mm length).
• Configuration: Available for series or parallel configurations:
  • Series: Increases voltage (e.g., 2 batteries in series = 7.4V for 3.7V batteries).
  • Parallel: Increases capacity while maintaining voltage (e.g., 2 batteries = double the mAh at 3.7V).

Types of 18650 Battery Holders

Multiple Battery Holder: Holds two or more batteries (e.g., 2S,  configurations for series connections or parallel setups).
