Why We Curate, Not Catalog
We focus on two widely used cylindrical formats. The table below gives buyers a quick first-pass choice before requesting matching support.
| Decision field | 18650 | 21700 |
|---|---|---|
| Diameter / height | 18mm / 65mm | 21mm / 70mm |
| Capacity range | 2000-3500mAh | 3000-5000mAh |
| Discharge range | 3C-15C options | 3C-10C options |
| Pack design | More cells, finer configuration granularity | Fewer cells, simpler BMS and busbar design |
| Typical use | Power tool, medical, compact instrument pack | AGV, e-bike, ESS, portable power station |
How We Select
Three steps from 40+ candidates to 8 trusted cells.
1. Evaluate
We rigorously test 40+ cell models for real-world capacity, cycle life, discharge rate, and internal resistance. Not datasheet claims — measured results.
2. Verify
Batch consistency audits. Certification verification (UN38.3, IEC62133, UL, CE). Factory assessment. Supply chain stability analysis.
3. Recommend
Only the cells that pass every check earn a place in our catalog. We then match the optimal cell to your specific application requirements.
