In the world of remote-controlled (RC) vehicles, the quality of your power source directly influences your performance. Whether you're racing, flying, or bashing, having the right battery means the difference between winning and stalling. At HobbyKing, we understand what true RC enthusiasts need—power, durability, and performance.

This is why our line of LiPo and Li-Ion batteries has become the gold standard in the RC industry. In this article, we’ll break down our best options across voltages and capacities, including the popular 11.1v battery, 22.2v lipo, 7.4v 800mah 2s, and 3.7v li-ion battery, while demonstrating why HobbyKing remains a trusted source worldwide.

1. Understanding Battery Basics: LiPo vs Li-Ion

Before diving into models, let’s clarify the difference between LiPo (Lithium Polymer) and Li-Ion (Lithium-Ion) batteries:

  • LiPo batteries offer higher discharge rates, lower weight, and flexibility in shape, making them ideal for drones, cars, and airplanes.
  • Li-Ion batteries boast longer lifespan, higher energy density, and safer construction, perfect for handheld devices and backup power.

HobbyKing offers both options, and each has its place depending on your RC setup.

2. 11.1V Battery: A Balanced Choice for Performance and Efficiency

The 11.1v battery (3S LiPo) is one of the most common choices among RC hobbyists. With its balanced voltage and manageable size, it powers drones, boats, and airplanes with precision.

At HobbyKing, our 11.1v battery packs are available in various capacities (from 1000mAh to 5000mAh), offering flexibility for flight time, speed, and weight management.

Benefits of HobbyKing 11.1v batteries:

  • Consistent power delivery
  • Ideal for mid-sized drones and planes
  • Stable voltage under high loads

Our Turnigy 11.1v 2200mAh 3S 25C LiPo Pack, for example, is a fan-favorite for FPV flyers seeking reliable performance without excess weight.

3. 22.2V Lipo Battery: Pure Power for High-Performance RC Setups

When your RC car or drone demands intense bursts of energy, nothing delivers like a 22.2v lipo battery (6S). This is the battery of choice for racers and professionals who need peak voltage with minimal sag.

The Turnigy Rapid 6000mAh 6S 100C LiPo Battery Pack, for example, is a beast—made for those who want to push their limits on the track.

Key Features of HobbyKing 22.2v LiPo:

  • Up to 200C burst discharge
  • Heavy-duty XT90 connectors
  • Low internal resistance
  • Perfect for competition-level RC racing

If you're serious about RC car racing or high-end drones, a 22.2v lipo battery is the powerhouse you need—and HobbyKing delivers it at an unbeatable value.

4. 7.4V 800mAh 2S: Compact, Lightweight & Ideal for Mini RCs

Looking for a battery for your small-scale RC cars or beginner drones? The 7.4v 800mah 2s battery from HobbyKing offers the perfect balance of lightweight design and consistent output.

Why choose the 7.4v 800mah 2s?

  • Compact size fits smaller RC models
  • Excellent for kids’ and beginner RC cars
  • Lightweight, enhancing agility

This battery is also ideal for educational robotics kits and mini quadcopters. Despite its size, it delivers high energy for extended sessions.

5. 3.7V Li-Ion Battery: Safety and Longevity Combined

For handheld transmitters, sensors, or backup modules, the 3.7v li-ion battery is a compact and safe choice. Unlike LiPo batteries, Li-Ion cells such as the HobbyKing 18650 3.7V 2600mAh battery offer greater longevity and safety during storage and charging.
