The "TechTracker" 7.4V 2200mAh Lithium-Ion Battery


Presenting the "TechTracker" a high-performance 7.4V 2200mAh Lithium-Ion Battery designed for IoT devices, tracking systems, and versatile backup applications.



Perfect for IoT and Tracking:

  • The "TechTracker" is tailored for the power demands of IoT devices, tracking solutions, and various backup applications, ensuring reliable performance when you need it most.

Features and Specifications:

  • JST XH 2.54 Connector: Comes with a convenient JST XH 2.54 connector for easy integration into your projects.
  • Shrink Paper Packing: Packaged with care in shrink paper, guaranteeing safe delivery and handling.



Why Choose Lithium-Ion Over Lead-Acid SMF Batteries:

1. Compactness and Portability:

  • Lithium-Ion: The "TechTracker" is incredibly lightweight and compact, making it ideal for space-constrained IoT devices.
  • Lead-Acid SMF: Lead-acid batteries are significantly bulkier and heavier, limiting their use in portable applications.

2. Energy Density:

  • Lithium-Ion: Offers a higher energy density, providing longer-lasting power in a smaller form factor.
  • Lead-Acid SMF: Lower energy density means they are less efficient and require more space for the same capacity.

3. Cycle Life:

  • Lithium-Ion: The "TechTracker" can handle hundreds of charge and discharge cycles, ensuring a longer operational lifespan.
  • Lead-Acid SMF: Lead-acid batteries have a limited cycle life and degrade faster over time.

4. Maintenance-Free:

  • Lithium-Ion: Requires minimal maintenance, with no need for periodic electrolyte checks or topping up.
  • Lead-Acid SMF: Requires regular maintenance to prevent dry-out and electrolyte leakage.

5. Efficiency:

  • Lithium-Ion: Offers higher charge and discharge efficiency, reducing energy waste.
  • Lead-Acid SMF: Suffers from energy loss due to self-discharge and low efficiency.

6. Environmental Impact:

  • Lithium-Ion: Environmentally friendly with no toxic heavy metals and lower CO2 emissions during manufacturing.
  • Lead-Acid SMF: Contains hazardous lead and poses disposal challenges.




Make the smart choice with the "TechTracker" Lithium-Ion Battery, offering compactness, efficiency, and longevity that outshines traditional lead-acid SMF batteries. Upgrade your projects and enjoy reliable, long-lasting power for your IoT devices and tracking systems. Order now and experience the difference! 🌐🔋
