LiHV, also known as Lipo High Voltage Battery or Lipo HV Battery, is available in fully charged voltages of 4.35V, 4.4V, and 4.45V. In the RC hobby, the most common type is the 4.35V LiHV. But what distinguishes LiHV from the traditional Lipo battery, which has a fully charged voltage of 4.2V?
Next, we will provide a detailed comparison through practical tests, recording the voltage and capacity changes from full charge to minimum charge for both battery types. This information will be presented in charts to guide you on the correct usage of LiHV and Lipo batteries, helping you extend their lifespan.

Frequently Asked Questions
Q1: Which is better, LiHV or Lipo Battery?
Compared to Lipo batteries, LiHV batteries have a higher discharge voltage and larger capacity, providing greater discharge power and extended run time. However, LiHV batteries are more expensive to manufacture and are commonly used in RC racing batteries.
Q2: What is a healthy cell voltage gap for Lipo and LiHV batteries?
A cell voltage gap greater than 300mV is generally considered too large. A small cell voltage gap indicates good battery quality.
Q3: What is the safest charging current for Lipo and LiHV batteries?
The recommended charging rate is 0.2C, so the safest charging current is equal to the battery capacity (Ah) multiplied by 0.2C.
Q4: What should the cutoff voltage be for Lipo and LiHV batteries?
The cutoff voltage should be set between 3.3V and 3.5V.
