Product Description
The 18650 is the most widely used rechargeable lithium-ion cell format in the world - trusted by manufacturers of laptops, power tools, electric vehicles, and countless portable devices. This 2200mAh cell provides a reliable balance of energy density, discharge performance, and longevity in a compact cylindrical package measuring just 18mm x 65mm.
With a nominal voltage of 3.7V and a fully charged voltage of 4.2V, this cell delivers consistent power output throughout its discharge curve. Rated for 300-500 full charge cycles, it offers long-term value for both prototyping and production-grade applications. The standardized 18650 form factor ensures compatibility with a vast ecosystem of battery holders, charging modules (such as TP4056), and battery management systems (BMS).
Whether you are building a custom lithium battery pack, powering a solar energy storage system, upgrading a flashlight, or prototyping an IoT device, this cell provides the dependable energy foundation your project requires.
Key Features
- 2200mAh Capacity: Ample energy storage for extended runtime in portable and embedded applications.
- 3.7V Nominal Voltage: Standard Li-ion voltage compatible with most 3.3V and 5V circuits via regulators.
- Industry-Standard 18650 Form Factor: Universal compatibility with holders, chargers, BMS boards, and battery pack configurations.
- Rechargeable (300-500 Cycles): Hundreds of charge/discharge cycles for cost-effective, long-term use.
- High Energy Density: Compact size with significant energy output - ideal for space-constrained designs.
- Lightweight Construction: Approximately 45g per cell, suitable for weight-sensitive portable projects.
- Wide Operating Temperature: Performs reliably from -20 degreesC to 60 degreesC during discharge.
- Flat Top / Button Top Variants: Check listing for terminal style to match your holder or contact configuration.
- Versatile Series & Parallel Configurations: Combine multiple cells to achieve higher voltages (series) or greater capacity (parallel) for custom battery packs.
Why Choose This?
- 100% authentic cells sourced from trusted and authorized suppliers
- Genuine rated capacity - no inflated or misleading mAh claims
- 1-5 day shipping, 7-8 day delivery from Bengaluru warehouse to most of India
- Expert technical support for battery pack design and charging circuit guidance
- Ideal for individual prototyping or bulk orders for production builds
Project Ideas
- Custom Battery Packs: Wire multiple 18650 cells in series or parallel with a BMS to create custom lithium battery packs for drones, e-bikes, robots, or UPS systems.
- Solar Energy Storage: Pair with a solar charge controller and TP4056 module to build an off-grid solar power bank or solar-powered IoT sensor node.
- Portable Power Banks: Build your own USB power bank using 18650 cells and a power bank PCB module - customize capacity to your exact needs.
- High-Performance Flashlights & Torches: Upgrade or power tactical flashlights that require reliable, high-drain 18650 cells.
- Arduino & ESP32 Portable Projects: Power microcontroller-based projects for hours - perfect for data loggers, weather stations, GPS trackers
