26700 battery

The 26700 Lithium-ion cell is a high-capacity power solution engineered for high-drain applications, offering a superior balance of energy density and structural stability compared to traditional 18650 or 26650 formats.

The 26700 battery cell represents a strategic evolution in cylindrical battery geometry. With dimensions of 26mm in diameter and 70mm in height, this format allows for a significantly larger internal volume than the standard 18650, translating to capacities that typically range from 4000mAh to 5500mAh.

Available in both NCM (3.7V) for maximum energy density and LiFePO4 (3.2V) for extreme safety and cycle life, the 26700 cell features a robust steel casing and a high-pressure safety vent. Engineers favor this model for its thermal efficiency; the larger surface area allows for better heat dissipation during high-rate discharge. Common modular configurations include:

  • 12V (4S / 3S): For marine and RV house batteries.
  • 24V / 36V: Preferred for mid-range electric scooters and wheelchairs.
  • 48V (13S / 15S): The standard for home energy storage systems and telecommunication backups.

Comprehensive Application Scenarios

The versatility of the 26700 cell has seen it dominate several high-growth markets:

  • Electric Micro-Mobility: Powering e-bikes, cargo trikes, and high-speed scooters that require sustained torque.
  • Portable Power Stations: Serving as the core energy unit for outdoor camping power banks and emergency jump starters.
  • Industrial Automation: Reliable power for AGVs (Automated Guided Vehicles) and robotics in warehouse environments.
  • Renewable Energy Storage: Storing solar and wind energy for off-grid lighting and residential ESS.
