Custom 26650 Battery Packs Manufacturer
Nuranu Battery designs and manufactures custom 26650 battery packs for applications requiring higher capacity, excellent durability, and stable power output. Compared with traditional 18650 cells, 26650 batteries offer larger physical dimensions and higher capacity, making them ideal for equipment that requires extended operating time and fewer recharge cycles.
Our engineering team provides complete battery pack development services, including cell selection, pack configuration, BMS integration, enclosure customization, testing, and OEM/ODM manufacturing.
What Is a 26650 Battery?
A 26650 battery is a cylindrical lithium-ion cell measuring approximately:
- Diameter: 26mm
- Length: 65mm
Compared with 18650 and 21700 cells, 26650 batteries typically offer:
- Higher capacity
- Longer runtime
- Improved thermal performance
- Better durability under demanding conditions
This makes them suitable for industrial equipment, energy storage systems, backup power solutions, and high-performance electronic devices.
Why Choose Custom 26650 Battery Packs?
Higher Capacity for Longer Runtime
26650 battery cells typically offer capacities ranging from:
| Cell Type | Typical Capacity |
|---|---|
| 18650 Cell | 2000–3500mAh |
| 21700 Cell | 4000–5000mAh |
| 26650 Cell | 4500–6000mAh+ |
This makes 26650 battery packs ideal for applications requiring extended operation between charging cycles.
Excellent Thermal Stability
The larger cell format allows improved heat dissipation, helping maintain stable performance during demanding operating conditions.
Benefits include:
- Reduced heat buildup
- Improved safety
- Longer battery lifespan
- Better high-load performance
Cost-Effective Pack Design
Because fewer cells may be needed to achieve a target capacity, 26650 battery packs can offer:
- Simpler pack architecture
- Lower assembly complexity
- Improved reliability
- Easier maintenance
