LiHV Batteries

What Is a LiHV Battery

You may have heard about lihv batteries if you enjoy RC models or drones. A lihv battery stands for Lithium High Voltage. This type of battery uses advanced lithium chemistry to reach a higher voltage per cell than standard lithium batteries. You can charge each cell in a lihv battery up to 4.35 volts, while regular lithium polymer (LiPo) batteries only go up to 4.2 volts per cell. Some brands even allow charging up to 4.45 volts per cell.

This high voltage output gives your RC models and drones more power y longer run times. The extra voltage means your drone can fly faster and last longer in the air. RC cars and planes also get a boost in speed and performance. Lihv batteries use a modified chemical matrix that supports higher voltage and reduces voltage sag. This means you get steady power, even when you push your model hard.

Consejo: Always use a charger that supports lihv batteries. Charging with a standard LiPo charger will not give you the full power and capacity of your lihv battery.

Here is a table that shows the main differences in chemistry and structure between lihv batteries and standard LiPo batteries:

LiHV vs LiPo

You might wonder how lihv batteries compare to standard LiPo batteries. The biggest difference is the voltage. Lihv batteries can reach up to 4.35 volts per cell, while LiPo batteries stop at 4.2 volts. This higher voltage gives you a performance boost of about 8-10%. Your drone or RC car will have more thrust, faster speeds, and better response times. Lihv batteries also have higher energy density, so you get more power without adding extra weight.

Here are some key points to help you see the differences:

• Lihv batteries deliver a higher maximum voltage per cell (4.35V) than LiPo batteries (4.2V).
• The higher voltage means increased thrust, faster speeds, and longer flight times for RC models and drones.
• Lihv batteries show less voltage sag under heavy loads, so your model keeps strong power during use.
• You need a charger that supports lihv batteries to reach the full voltage and capacity.
• Lihv batteries degrade faster over time, so you may notice a drop in capacity after many charge cycles.
• These batteries are popular in racing drones, micro drones, and high-speed RC cars because of their power-to-weight advantage.

Nota: If you use a lihv battery in a device made for LiPo batteries, check if your device and charger can handle the higher voltage. Using the wrong charger or settings can damage your battery or device.

Lihv batteries have become the top choice for many RC and drone fans. You get more power, longer run times, and better performance. You must handle them with care and use the right equipment to enjoy all the benefits safely.

Technology

Voltage and Power

LiHV batteries use advanced lithium chemistry to deliver a high voltage output. You get more power from each cell because the voltage reaches up to 4.35V. This higher voltage means your RC model’s motor spins faster and produces more speed. For example, a 3500KV motor can reach much higher RPMs with a LiHV battery than with a standard lithium pack. The extra voltage adds up across multiple cells, giving you a real boost in total power. This high power output lets your drone or RC car accelerate quickly and reach top speeds. You also enjoy longer flight times because the battery holds more energy. The high energy density of LiHV technology means you get more performance without adding extra weight. This energy density advantage is important for racing and high-performance models.

Discharge and Stability

LiHV batteries support high discharge rates, which means they can release energy quickly when your model needs it most. You get stable power output during hard acceleration or fast maneuvers. The lithium chemistry in these batteries helps reduce voltage sag, so your RC model keeps strong and reliable power delivery throughout use. Stable power output is important for drones and cars that need quick bursts of speed. However, the high voltage and high energy density can cause more heat in the motor and ESC. You must make sure your system can handle the extra load. LiHV batteries give you stable power output, but you need to monitor temperature and avoid pushing the battery too hard.

Cycle Life

When you use LiHV batteries, you get great performance, but you trade off some longevity. LiPo batteries often last over 300 charge cycles if you take care of them. LiHV batteries, with their high voltage and high energy density, usually start to degrade and swell after only 30-40 cycles. This shorter battery longevity comes from the lithium chemistry that allows for more capacity but reduces how long the battery lasts. Official ratings may say both types last 200 to 400 cycles, but real-world use shows LiHV batteries wear out faster. If you race or fly often, you may need to replace your LiHV battery more often. Still, many users choose LiHV technology for its high power output and stable power output, even if it means shorter longevity.
