Description
High-Energy 26700 3.7V 5000mah Lithium-Ion Rechargeable Cell
Maximum Capacity & Premium Power Delivery
When standard 18650 or 21700 cells can’t give you the runtime your project demands, step up to the 26700 Lithium-Ion Cell. Engineered with a 3.7V nominal rating and a full 4.2V charge capacity, this beefier cylindrical cell is designed to deliver maximum energy density and prolonged power to high-drain devices.
Key Features
-
Massive Energy Density: The larger 26700 form factor (26 mm diameter by 70 mm length) allows for a significantly higher milliamp-hour (mAh) capacity than smaller cells, keeping your devices running much longer on a single charge.
-
True 3.7V Nominal Power: Delivers a strong, steady voltage profile that standard high-drain electronics, motors, and tools require for peak performance.
-
Excellent Discharge Rates: Built to handle demanding loads without severe voltage sag, making it highly reliable under heavy work conditions.
-
Cost-Effective Longevity: Supports hundreds of charge cycles with proper care, offering a reliable, long-term power solution that cuts down on replacement costs.

Versatile Applications
Thanks to its combination of high voltage and high capacity, the 26700 cell is the perfect choice for:
-
Custom EV & E-Bike Battery Packs: Build smaller, lighter packs with fewer cells while matching the capacity of older configurations.
-
High-Drain Tactical Flashlights: Provides the intense current needed for multi-thousand lumen output alongside massive runtime.
-
Power Tools & Gardening Equipment: Upgrades cordless tools that need high current and long endurance.
-
Portable Power Banks & DIY Electronics: A dream for hobbyists building custom outdoor power stations, robotics, or portable audio rigs.
Safety Note: This is an unprotected, high-performance industrial cell. Always use a high-quality Battery Management System (BMS) when building packs, and ensure your charger is explicitly rated for 4.2V max lithium-ion charging.
