Whether you’re into competitive RC racing, flying FPV drones, or just bashing around with your favorite RC truck, the battery you choose can make or break your experience. In the world of RC, performance is everything—and it all starts with the right power source.
At HobbyKing, we specialize in high-performance batteries for every type of RC enthusiast. In this guide, we’ll deep dive into the power-packed world of 50C, 100C, and 120C LiPo batteries, exploring the differences, use cases, and our top recommendations.
What Does “C Rating” Mean in a LiPo Battery?
The “C” rating on a LiPo battery refers to its discharge rate, or how quickly it can deliver its stored energy. Here’s what that means:
50C LiPo: A moderate-high discharge rate suitable for most drones, planes, and RC cars.
100C LiPo battery: A high-performance option offering rapid bursts of current, ideal for racing.
120C LiPo battery: Top-tier discharge capability for the most power-hungry applications.
The higher the C rating, the more powerful the battery becomes under load, making 100C and 120C LiPo batteries the go-to choice for racers and serious hobbyists.
⚡ Why Choose a 100C LiPo Battery?
A 100C LiPo battery strikes the perfect balance between power, weight, and reliability. It’s especially favored by:
RC car racers who need explosive acceleration out of corners
FPV drone pilots flying aggressive freestyle or racing lines
RC boat enthusiasts who require constant, high-current output
The Turnigy Rapid 6000mAh 4S 100C LiPo battery by HobbyKing is a standout performer in this class. Designed with low internal resistance and precision-matched cells, this battery delivers consistent voltage under heavy load—an essential trait for any serious RC competitor.
�� Key Features:
100C constant discharge
EC5 connector and JST-XH balance plug
Heavy-duty silicone wiring
Compact, soft-case design for easy mounting
Whether you’re upgrading your RC buggy or building a custom drone rig, this 100C LiPo battery from HobbyKing brings race-ready performance at a killer price point.
Is 50C Enough? The Power and Versatility of a 50C LiPo
While 100C and 120C batteries steal the spotlight, don’t underestimate the 50C LiPo. It’s a reliable, efficient choice for:
Beginner to intermediate pilots and drivers
Lightweight racing drones
Fixed-wing airplanes and gliders
A 50C discharge rate is typically more than enough for weekend flyers or casual racers who want power without overkill. HobbyKing offers a wide selection of 50C LiPo packs, from compact 2S and 3S models to higher-capacity 6S options.
Benefits of 50C LiPo Batteries:
Longer lifespan due to reduced thermal stress
Lower price compared to higher C-rated batteries
Great balance of power and endurance
If you’re flying something like a 5-inch FPV drone or a 1/10 scale buggy, a 50C LiPo could be the sweet spot you’ve been looking for.
When Only the Best Will Do: 120C LiPo Battery
For those pushing the limits of speed and torque, only a 120C LiPo battery will do. These batteries offer:
Instant throttle response
Peak performance under maximum load
The ultimate edge in high-stakes racing
120C LiPo batteries are often seen in top-tier drone racing circuits and competitive RC car races where milliseconds matter.
HobbyKing’s 120C LiPo Options Include:
Ultra-light soft pack designs
High-voltage (HV) variants for added punch
Wide range of sizes from 3S to 6S configurations
With HobbyKing, you can be sure your 120C battery pack has been tested and rated with real-world demands in mind. We ensure high energy density and tight cell matching for consistent, repeatable performance.
How to Choose the Right C Rating for Your RC Model
If you’re not sure whether to go with a 50C, 100C, or 120C LiPo battery, here’s a simple guide:
|
Model Type |
Recommended C Rating |
|
FPV Racing Drones |
100C - 120C |
|
Freestyle Drones |
50C - 100C |
|
RC Cars (Racing) |
100C - 120C |
|
RC Cars (Bashing) |
50C - 100C |
|
RC Airplanes |
50C |
|
RC Boats |
100C - 120C |
Choosing too low of a C rating can lead to voltage sag, overheating, and even battery damage. On the flip side, going too high might add unnecessary weight and cost. That’s why HobbyKing’s broad selection of C-rated LiPo batteries is perfect for fine-tuning your setup.
