Quality guarantee
Voltaplex values long-term relationships with clients and encourage our clients to performance test cells against official manufacturer specification sheets.
In Asia, 18650 batteries are binned by quality into A, B, and lower bins. C-bin batteries are often recycled from battery packs. Lower bin batteries will underperform and may be dangerous.
We will only provide A Grade cells, unless specifically required to otherwise, for example, some clients may prefer Grade B Chinese cells for low-cost ESS projects. We can also confirm batch-date code, run testing (like impedance/voltage/capacity), and handle other IQC requirements.

Battery specifications
The Sony VTC5 is perhaps the most notorious lithium-ion 18650 battery of all time - but wrongly so. Many vendors claimed it to be a 'step up' from the VTC4 but naming conventions are not that simple. Actually, the VTC5 was a step down for many people because of its max. cont. discharge rating is actually 10 amps lower. There is a lot of controversy surrounding this, as many trusted vendors falsely claim higher specs. This is all due to bad Chinese suppliers that exaggerate specs, and vendors that fail to enact due diligence and test their batteries thoroughly. Regardless the cell is still very popular and has many useful applications.
Battery specifications:
- Model: US18650VTC5
- Manufacturer: Sony
- Max. continuous discharge current: 30A
- Nominal capacity: 2600 mAh
- Nominal voltage: 3.6 V
- Discharge end voltage: 2.5 V
- Charging voltage: 4.20 +/- 0.05 V
- Standard charging current: 1.25 A
- Length: 65.20 mm
- Diameter: 18.35 mm
- Weight: 44.30 g

FAQs About Buying and Using 18650 Batteries in Bulk
Learn more about buying and using 18650 batteries in bulk through our frequently asked questions.
What’s the difference between protected and unprotected 18650 batteries?
Protected 18650 batteries include a built-in circuit for overcharge, over-discharge, and short-circuit protection. Unprotected cells offer raw performance but require external battery management systems.
Can I get 18650 batteries with specific discharge ratings?
Yes! Voltaplex offers 18650 battery cells with various discharge rates to support different system requirements.
How should I store 18650 batteries in bulk?
Store 18650 batteries in a cool, dry location away from metal objects, direct sunlight, or heat sources. Keep them partially changed and use protective cases for long-term storage.
Do 18650 battery cells have a shelf life?
Yes, most 18650 cells maintain optimal performance for 2 to 3 years if stored properly. Gradual capacity loss can occur over time due to natural chemical aging.
How Cylindrical Form Factors Benefit Custom Battery Designs
The uniform shape and standard dimensions of 18650 batteries simplify the custom battery pack assembly layout process.
Engineers can scale systems easily by aligning multiple 18650 cells in fixed arrays without adjusting for variable dimensions.
This form factor allows precise capacity planning, simplifies connection points, and supports automation in high-volume builds.
Voltaplex offers 18650 battery cells in bulk to meet the needs of teams developing modular, repeatable designs.
