What Is an 18.5V Lithium Battery Pack
An 18.5V lithium battery pack is built by connecting five 3.7V lithium-ion cells in series, creating a 5S configuration.
This structure provides higher operating voltage while keeping the design compact and lightweight.
Compared with traditional lead-acid or NiMH batteries, lithium-ion technology offers faster charging, longer lifespan, and more consistent performance.
That’s why it’s widely adopted in both industrial and commercial applications where reliability matters.
Why It’s a Popular Choice
Many engineers and designers choose 18.5V lithium battery packs because they deliver stable power without adding extra weight.
They are ideal for machines and tools that need smooth voltage under heavy load.
Thanks to advanced Battery Management Systems (BMS), each pack is protected against overcharge, overdischarge, short circuits, and temperature fluctuations.
This makes it a safe, durable, and easy-to-integrate energy solution for modern equipment.
Performance and Reliability
An 18.5V lithium battery pack maintains consistent output throughout its entire discharge cycle.
That means your device keeps performing at full strength until the very end — no sudden voltage drop or weak performance.
Each pack supports more than 500 charge cycles while maintaining excellent capacity retention.
At Jetray, we use premium lithium cells from Samsung, LG, and Panasonic to ensure every pack performs reliably even in demanding environments.
Typical Applications
These battery packs are widely used in industries where mobility, reliability, and long-lasting energy are essential.
You’ll often find them in:
Robots and AGVs
Medical devices such as monitors and portable ventilators
Solar lighting and renewable energy systems
Industrial testing tools and instruments
Communication and security equipment
No matter the application, the 18.5V pack ensures smooth, stable power for continuous performance.
How 18.5V Compares with Other Lithium Battery Packs
If you’ve used 3.6V, 7.4V, 11.1V, or 14.8V lithium battery packs before, you might wonder where 18.5V fits in.
Each voltage range serves different product needs — from small electronics to high-power industrial tools.
| Battery Voltage | Configuration | Main Advantage | Common Applications |
|---|---|---|---|
| 3.6V | 1S | Compact and lightweight for small devices | Flashlights, sensors, IoT gadgets |
| 7.4V | 2S | Balanced power and size for portable use | Cameras, handheld tools, small drones |
| 11.1V | 3S | Stable output for mid-range systems | RC models, testing devices, medical tools |
| 14.8V | 4S | Stronger power for larger equipment | Robots, communication devices, LED lighting |
| 18.5V | 5S | High energy output and long runtime | AGVs, solar lighting, power tools, automation |
