What Is a LiHV Battery?
A LiHV battery (High Voltage LiPo) is an enhanced version of a traditional LiPo battery that allows a higher maximum charge voltage per cell. While standard LiPo batteries charge to 4.20V per cell, LiHV batteries are designed to safely charge up to 4.35V per cell, providing more usable energy without increasing physical size.
For RC applications, this higher voltage translates into longer runtime, improved throttle response, and more consistent power delivery—especially noticeable during high-load acceleration or extended flight sessions.
LiHV vs Standard LiPo: Key Differences
| Feature | Standard LiPo | LiHV (High Voltage LiPo) |
|---|---|---|
| Max Charge Voltage (per cell) | 4.20V | 4.35V |
| Energy Density | Standard | Higher usable capacity |
| Power Output Under Load | Drops earlier | More stable voltage |
| Physical Size | — | Same size as LiPo |
| Compatibility | All LiPo chargers | Requires LiHV-capable charger |
Why Choose LiHV for FPV Drones?
In FPV applications, LiHV batteries are popular because they deliver a higher initial voltage and maintain it longer during aggressive throttle use. This results in crisper throttle response, reduced voltage sag, and slightly longer flight times compared to equivalent LiPo packs.
LiHV FPV batteries are especially well suited for freestyle drones, cinewhoops, and lightweight racing setups where efficiency and power-to-weight ratio matter most.

Why Use LiHV Batteries in RC Cars?
For RC cars and trucks, LiHV batteries provide stronger punch off the line and more consistent power during long runs. When combined with hard case construction, LiHV packs are ideal for racing and high-load environments where durability and voltage stability are critical.
Drivers often choose LiHV hard case batteries to maximize performance without moving to a higher cell count, making them a practical upgrade for 2S, 3S, and 4S setups.

LiHV Safety and Charging Notes
LiHV batteries should always be charged using a charger that explicitly supports LiHV mode. Charging a LiHV battery as a standard LiPo will limit it to 4.20V per cell, which is safe but does not utilize the full capacity of the pack.
As with all high-performance LiPo batteries, proper storage voltage, balance charging, and physical inspection are essential for long-term reliability and safety.
