High-Voltage LiHV Battery Solutions: 3.80V, 3.85V, & 3.90V Rechargeable Cells

Standard 3.7V LiPo cells are the industry baseline, but for applications demanding higher energy density and a flatter discharge curve, High-Voltage Lithium Polymer (LiHV) technology is the superior choice. LiPol’s LiHV range provides a significant performance boost in a lighter, more compact footprint.

Key Benefits Section of High Voltage LiPo Batteries

• Enhanced Energy Density: More Watt-hours (Wh) per gram compared to standard LiPo.

• Higher Voltage Ceiling: Higher terminal voltage means more punch for motors and longer operational windows for electronics.

• Reduced Weight: Achieve the same power output as a 3.7V pack but with a smaller, lighter LiHV configuration.

• Stable Discharge: Engineered to maintain higher voltage under load, preventing “sag” during peak performance.

Why Choose LiPol High-Voltage Batteries?

Increased Capacity in the Same Footprint: By increasing the voltage ceiling, we pack up to 20% more power into the same physical space as a standard 3.7V battery.

Reduced Voltage “Sag”: LiHV cells maintain a higher operating voltage throughout the discharge cycle. For a motor-driven application (like a drone or medical pump), this means more consistent power even as the battery nears empty.

Weight Efficiency: For aerospace and UAV clients, weight is everything. Our 3.85V and 3.90V cells allow you to reduce the number of cells in a pack while maintaining the same total voltage, significantly cutting down on weight.

Manufacturer Warning: To ensure the safety and longevity of your LiHV investment, always use a dedicated LiHV-compatible charger. While a standard charger will only fill these to 4.20V (leaving them undercharged), an LiHV charger allows them to reach 4.35V or 4.40V safely.

Certifications: All LiPol High-Voltage cells are RoHS & REACH compliant, with available UN38.3 and IEC62133 certification for global shipping and medical-grade integration.

• The Advantage: The industry “sweet spot.” It provides roughly 15% more energy density than standard cells, allowing for longer mission profiles in weight-critical designs.

3.90V Extreme High-Voltage LiPo Batteries

• Best For: Racing drones, professional cinematography equipment, and high-drain industrial tools.

• The Advantage: Maximum power output for high-torque applications. Note from our Expert: These cells require precise charging protocols to manage heat generation and ensure long cycle life.

Technical Comparison: Standard LiPo vs. High-Voltage (LiHV) Series

Caution from the LiPol Engineering Team: To unlock the full potential of our LPHV series, you must use a charger with a ‘LiHV’ mode. Charging these cells on a standard 3.7V LiPo setting will only charge them to 4.20V, resulting in a loss of potential runtime. Conversely, never attempt to charge a standard 3.7V battery to 4.35V.

Always verify that your charger supports LiHV settings. Charging a standard 3.7V battery to 4.35V is dangerous and can lead to thermal runaway. Conversely, charging a 3.85V battery with a standard 4.20V charger is safe but will result in roughly 15% lost capacity

Understanding High Voltage Rechargeable LiPo Batteries

Choosing the right LiHV battery involves understanding your needs and evaluating various factors such as voltage compatibility, capacity, discharge rate, size, charging requirements, cycle life, safety features, and brand reputation. By considering these elements carefully, you can select a battery that enhances your device’s performance and ensures safety and longevity.

What Are High Voltage LiPo Batteries?

High-voltage LiPo batteries are cells designed to operate at a nominal voltage higher than the standard 3.7V LiPo batteries. These LiPo batteries can increase power output and energy density, making them suitable for specific applications that demand enhanced performance.

LiHV battery-high Voltage Rechargeable LiPo Battery

In summary, while both LiHV and standard LiPo batteries share similar chemistry and characteristics, the primary distinction lies in their voltage capabilities and performance metrics, with LiHV representing an advanced option within the lithium polymer battery family.

• a LiHV (Lithium High Voltage battery) is a rechargeable LiPo battery. Here are the key points that clarify this relationship: Definition: LiHV batteries are a specialized form of lithium polymer (LiPo) batteries designed to operate at higher voltages. While traditional LiPo batteries typically have a maximum voltage of 4.2V per cell, LiHV batteries can be charged up to 4.35V per cell. This higher voltage allows them to deliver more energy and potentially longer device runtimes;
• Rechargeable Nature: Like standard LiPo batteries, LiHV batteries are rechargeable and utilize lithium-ion technology. They can be cycled multiple times, making them suitable for applications that require frequent charging and discharging.
• Performance Characteristics: LiHV batteries generally offer higher energy density, stable power delivery, and the ability to handle high discharge rates compared to traditional LiPo batteries. This makes them particularly popular in high-performance applications such as drones and remote-controlled vehicles.
• Charging Requirements: Due to their higher voltage capabilities, LiHV batteries require specific chargers to accommodate the charging voltage of 4.35V per cell. Using a charger designed for standard LiPo batteries may lead to overcharging and potentially hazardous situations.
• Applications: LiHV batteries are widely used in scenarios where weight and size are critical, such as in racing drones and other high-performance electronic devices.

Types of High Voltage LiPo Batteries

• 3.80V High Voltage LiPo Batteries:
  Applications: Commonly used in drones, RC cars, and portable devices that require a balance of power and weight.

How do you choose a suitable High Voltage LiPo Battery?

When choosing a suitable LiHV battery (Lithium High Voltage), several important factors must be considered to ensure that you select the right battery for your specific needs. Here’s a comprehensive guide based on the search results: Key Factors to Consider

• Voltage Compatibility: Ensure that the voltage of the LiHV battery matches your device’s requirements. LiHV batteries typically have a nominal voltage of 3.8V to 4.35V per cell, compared to standard LiPo batteries, which are usually rated at 3.7V to 4.2V. Using a battery with the wrong voltage can damage your device or lead to inefficient performance.
• Capacity: A battery’s capacity, measured in milliamp hours (mAh), indicates how much energy it can store. Choose a battery that meets or exceeds your device’s energy requirements to ensure optimal performance and runtime.
• Discharge Rate (C Rating): The discharge rate indicates how quickly the battery can deliver power. A higher C rating means the battery can provide more current without overheating, which is crucial for high-performance applications like drones and racing cars.
• Weight and Size: Consider the battery’s physical dimensions and weight, especially for portable devices with limited space. A lighter battery can enhance the device’s overall performance and handling.
• Charging Requirements: Check if your charger is compatible with LiHV batteries, as they require a maximum charging voltage of 4.35V per cell. Using an incompatible charger can lead to overcharging or damage.
• Cycle Life: Evaluate the battery’s expected cycle life, which refers to how many charge and discharge cycles it can undergo before its capacity significantly decreases. LiHV batteries may have a shorter cycle life than traditional LiPo batteries, so consider how often you will use the battery.
• Safety Features: Look for batteries with built-in safety features such as overcharge protection, short-circuit protection, and thermal management systems to prevent accidents during use.
• Brand Reputation: Opt for reputable brands known for their quality and reliability in producing lithium batteries. This ensures you receive a product that meets safety standards and performs well.
