The Ultimate Buying Guide to High Discharge LiPo Batteries: Top Picks at 100C/120C

Introduction

In the RC (radio control) world, battery performance directly determines your machine's explosive power and endurance. Especially for racing RC cars, FPV drones, or industrial robots, the high discharge LiPo battery is at the very heart of your system. In this guide, we’ll walk you through:

- What is a high discharge rate LiPo battery?
- How do 100C and 120C batteries differ from standard ones?
- How to choose the best high-power battery from leading brands like Hoovo and HobbyKing
- Recommended models such as the 6000mAh 6S (22.2V) 100C LiPo Battery
- Best-selling options on HobbyKing

 1. What is a High Discharge LiPo Battery?

LiPo (Lithium Polymer) batteries are rated by their discharge rate, usually denoted by the C rating. A 30C battery can discharge at 30 times its capacity. A 100C battery delivers a massive burst of current, perfect for high-power demands. ≥50C is considered high discharge. 100C and 120C LiPo batteries are ideal for professional use in racing, robotics, and FPV systems.

Ø Key Characteristics of High Discharge LiPo Batteries:

1. High C-Rating (Discharge Rate)

The “C” rating refers to the maximum current the battery can discharge.

A higher C rating (like 100C, 120C, etc.) means the battery can provide more amps without overheating or becoming unstable.

Formula:
Max Discharge Current (A) = C-Rating × Capacity (Ah)
For example: a 5200mAh (5.2Ah) 100C battery can discharge at:
5.2 × 100 = 520A

2. Excellent Burst Performance

High discharge LiPos can handle rapid bursts of current, which is crucial for:

Fast acceleration in RC cars

Sudden throttle spikes in drones

Sharp maneuvers in RC planes

3. Stable Voltage Under Load

These batteries are engineered to maintain voltage stability during high current draw, reducing voltage sag and improving overall performance.

4. Reinforced Internal Structure

Often built with better-quality cells, thicker tabs, and robust wiring to handle the stress of high current loads.

2. 100C vs 120C LiPo Batteries: Which Should You Choose?

In high-performance RC equipment, the battery life directly affects the explosive power and sustained performance of the whole vehicle. As the world's leading RC battery brand, HobbyKing provides a variety of 100C and 120C LiPo batteries to help players of different specifications maximize performance.
Although in theory 100C = 100 times the battery capacity discharge current, and 120C = 120 times, the high-rate LiPo batteries produced by HobbyKing have been rigorously tested, and their nominal C value is closer to actual performance.

For example:

A HobbyKing Turnigy Graphene 5200mAh 100C battery can continuously provide 520A discharge current, suitable for 1/10 and 1/8 off-road vehicles.

The HobbyKing Graphene Panther 5200mAh 120C series is designed for racing players, supporting up to 624A instantaneous discharge output, and can still maintain voltage stability under high-intensity operation.
If you're a pro: choose 120C
For balanced performance and price: choose 100C

Choose 100C scenario (HobbyKing model recommended)

Suitable for the following players:

• Intermediate and advanced players
• Focus on cost-effectiveness and stability
• High frequency of vehicle use but not extreme racing

Recommended models:

Turnigy Graphene Panther 5000mAh 4S 75C

Zee 3S 5200mAh 100C Hardcase LiPo Battery

Advantages:

• Affordable price
• Discharge capacity is sufficient to cope with more than 90% of RC scenarios
• Easier to adapt to conventional ESC and motor systems

Choose 120C scenario (HobbyKing model recommended)

Suitable for the following players:

• Competitive and competition-level players
• Need extreme acceleration or heavy-load climbing
• Use high-current systems (such as high-KV motors or large brushless drives)

Recommended models:

Turnigy Graphene Panther 5200mAh 4S 120C

Hoovo 6S 100C 5200mAh LiPo for 1/8 Buggies & Truggies

Advantages:

• Stronger voltage retention
• Better resistance to thermal decay
• Better performance in scenarios such as racing and extreme drifting

HobbyKing Tips: How to choose the right C value?

• Check the current range supported by your ESC

If the upper limit is 150A, using 5200mAh 100C is completely sufficient (ideal output 520A).

• Depends on how you use your car

100C is recommended for regular off-road/flat running; 120C is safer for competitive climbing and extreme speed racing.

• Reasonably balance weight and battery life

High C value batteries are slightly larger in size, and the size of the battery compartment needs to be confirmed in advance.

Whether you are an RC enthusiast who focuses on stability or a racing player who pursues extreme speed, HobbyKing can provide you with the best 100C or 120C high-rate LiPo battery solutions. Reasonable matching of equipment is the key to maximizing performance.
