As a specialized lithium-ion manufacturer, Shenzhen Huayousheng Energy Technology Co., Ltd. (FYW Power) supplies Grade A 18650 cylindrical cells in 2000mAh, 2200mAh, 2500mAh and 2600mAh capacities. Every cell is built around one principle: a battery must remain safe and stable throughout its entire service life, not just on the day it ships.
These 3.7V 18650 rechargeable lithium-ion cells are produced with consistent material and process control, then 100% capacity tested and sorted before shipment. Tight matching of capacity, voltage and internal resistance makes them reliable building blocks for battery packs, consumer electronics and energy-storage projects.
| Model | Type | Nominal / Min. Capacity | Cycle Life (0.5C, 25°C) | Max. Series / Parallel |
|---|---|---|---|---|
| 18650-2000mAh | Energy Storage | 2000 / 1950mAh | ≥ 300 cycles | 7P7S |
| 18650-2200mAh | Digital / Consumer | 2200 / 2150mAh | ≥ 300 cycles | 3P2S |
| 18650-2500mAh | Digital / Consumer | 2500 / 2450mAh | ≥ 400 cycles | 7P7S |
| 18650-2600mAh | Digital / Consumer | 2600 / 2550mAh | ≥ 400 cycles | 7P7S |
Safety is designed into the cell structure, not added afterwards. Each unit uses a rugged nickel-plated steel shell and is assembled under strict quality control to reduce swelling, short-circuit and thermal-runaway risks.
Stable performance is what keeps a battery pack consistent in the field — and it is what our customers value most.
