🔋 RPE Now Offering 4680 Battery Cells for Project-Based Applications!
At Rechargeable Power Energy, we’re excited to announce that starting this month, 4680 cylindrical lithium-ion battery cells will be available for purchase through our project-based sales program!
Whether you’re building high-performance EV packs, energy storage systems, or custom high-drain applications — the 4680 format represents a major leap forward in energy density and thermal efficiency.
Why the 4680 Battery Cell Matters
The 4680 cell (46mm diameter, 80mm height) is designed to pack more power, energy, and efficiency into a single unit. Tesla helped put this format in the spotlight, but demand has grown across multiple industries for larger-format cylindrical cells that:
-
Provide up to 6X the energy output
-
Deliver 5X higher energy density
-
Improve thermal management and reduce the need for additional structure or modules
These benefits make 4680 cells ideal for:
-
Electric vehicle battery systems
-
Large-scale solar storage
-
High-demand robotics or drone platforms
-
Custom industrial pack designs
Comparing 4680 vs 21700 vs 18650 (and 26650)
Let’s break down how 4680 cells compare to the traditional cylindrical sizes we also offer:
| Cell Type | Diameter x Height | Capacity Range | Energy Density | Use Case Highlights |
|---|---|---|---|---|
| 18650 | 18mm x 65mm | ~2500–3500mAh | Moderate | Power tools, e-bikes, flashlights |
| 21700 | 21mm x 70mm | ~4000–5000mAh | High | EVs, drones, energy storage |
| 26650 | 26mm x 65mm | ~4000–5500mAh | High w/ higher output | Heavy-duty e-bikes, torches, robotics |
| 4680 | 46mm x 80mm | ~9000–15000mAh+ | Extremely high | EVs, solar grid storage, industrial packs |
While 18650 and 21700 cells continue to dominate the market for their versatility, the 4680 cell is shaping the future for those who need maximum performance in compact configurations.
We also continue to support 26650 cells, which offer a solid middle ground with higher current output in a slightly wider format — great for builders who want more punch without moving to a larger architecture.
Custom Orders for R&D, B2B, and OEM
RPE is proud to serve B2B customers and innovators across North America. For OEMs, fleet managers, and battery pack designers, our 4680 cells are available via custom or project-based requests. This allows us to:
