Features of High-Voltage Lithium-Polymer Cells
Blumoti high-voltage LiPo cells deliver more energy in a compact pouch design. The series covers capacities from 100mAh to over 10,000mAh. Available voltage platforms include 3.8V/4.35V, 3.85V/4.4V, and 3.9V/4.45V.
Higher Energy Densit
High-voltage cells store more energy within the same battery space. Selected models reach energy densities of up to 680Wh/L. This makes them a strong choice for products with strict size and weight limits.
Longer Device Runtime
A higher voltage platform increases total watt-hour output. Your device can run longer without using a larger battery. It can also reduce charging frequency.
Stable Voltage Output
High-voltage cells maintain a higher voltage level during discharge. This supports steady device performance. It is useful for electronics that require consistent power throughout the discharge cycle.
Flexible Customization
The cell can be customized around your available battery space. We support custom dimensions, capacity, wires, connectors, PCM, NTC, labels, and packaging.
Protection Options
A protection circuit can be added for overcharge, over-discharge, overcurrent, and short-circuit protection. The protection design can be matched to the device and its power requirements.
Designed for Premium Products
High-voltage LiPo cells are ideal when runtime, weight, and internal space are key design priorities. They help product developers create slimmer devices without giving up battery life.
Applications for High-Voltage LiPo Batteries
Wearable and Smart Devices
High-voltage LiPo batteries are ideal for smartwatches, fitness trackers, smart glasses, AR devices, and wireless sensors. Their compact size helps reduce product weight. Their high energy density also supports longer runtime.
Consumer Electronics and Portable Audio
Common applications include smartphones, tablets, e-readers, TWS charging cases, headphones, Bluetooth speakers, handheld gaming devices, and mini projectors. High-voltage cells provide more energy without increasing battery size.
Medical, Healthcare, and Personal-Care Devices
These batteries can power glucose meters, patient monitors, portable diagnostic tools, beauty devices, mini massagers, and other rechargeable healthcare products. Custom sizes, wires, connectors, and protection circuits are available.
IoT and Industrial Handheld Equipment
High-voltage LiPo batteries are widely used in smart trackers, monitoring devices, barcode scanners, mobile POS terminals, logistics PDAs, inspection tools, and rugged handheld computers. Larger-capacity cells can support a full work shift.
Professional and High-Capacity Equipment
Large high-voltage cells are suitable for portable testing instruments, field equipment, industrial control terminals, robotic systems, backup power modules, and other long-runtime devices. Capacities above 10,000mAh are available for demanding applications.
Knowledge Center for High-Voltage Polymer Cells
A high-voltage LiPo cell has a higher voltage platform than a standard LiPo cell, which is typically charged up to 4.2V. For example, a high-voltage LiPo cell may have a full-charge voltage of 4.35V or 4.4V.
Its main advantage is that it can improve energy density without changing the battery size, helping extend device runtime. It can also provide a more stable discharge voltage, which supports better device performance.
High-voltage LiPo cells are commonly used in devices that are sensitive to internal space and weight, such as wearable devices, beauty instruments, smart hardware, and other compact electronics.
The biggest difference between high-voltage LiPo cells and standard-voltage LiPo cells is the voltage platform. A high-voltage LiPo cell can be charged up to 4.45V, while a standard LiPo cell is typically charged up to 4.2V.
This higher voltage directly increases the energy output. With the same capacity, a high-voltage LiPo cell can deliver more energy, helping improve device runtime and overall battery performance.
For buyers, the main value of high-voltage LiPo cells is not just higher voltage, but better energy performance within limited space.
In general, high-voltage LiPo cells are considered an upgrade from standard LiPo cells, especially for devices that need better runtime without changing the battery size.
However, several compatibility factors should be confirmed before upgrading. The most important one is whether the charger can fully charge the high-voltage LiPo cell. Other details, such as PCM design, connector type, and overall pack compatibility, should also be checked.
If the device is designed to support high-voltage LiPo cells, upgrading to a 3.85V cell can be a good way to improve energy output. If not, a standard 3.7V LiPo cell may still be the safer and more suitable choice.
