700+ Class RC Helicopter Battery Guide
The 700–800 class RC helicopters represent the top tier of performance in the hobby. Flying with 690–800mm blades, they are built for high power, long flight times, and extreme 3D capability. Selecting the right 700 class RC heli battery or 12S helicopter battery is the key to unlocking their full potential.
Voltage & Capacity Tips
- 12S (2×6S) · 5000–5500mAh: Most common setup for 700 size 3D helis—delivers explosive power and precise response.
- 12S · 6000–7000mAh: Perfect for long flights and scale 700–800 models, offering extra duration with stable performance.
- High C-rate packs: For aggressive 3D, a 120C 6S LiPo battery ensures punch, safety, and consistent output.
Discover our full range of high-performance packs: 6S LiPo batteries (pair for 12S setups) and 12S LiPo batteries.
FAQ: 700 Class Helicopter Batteries
Q1: Do I need a 12S battery for my 700 heli?
A: Yes—most 700 and 800 size helicopters are designed for 12S helicopter batteries. You can easily achieve this by connecting two 6S LiPo batteries in series, which is the standard setup for high-power RC helis.
Q2: What’s the difference between a 700 and an 800 class heli?
A: Both run 690–800mm blades, but 800 class machines carry larger packs (up to 7000mAh 6S pairs), offering longer flight times and more stability for scale or cinematic flying.
Q3: Which connectors are most common?
A: For 700+ class helicopters, EC5 and XT90 connectors are standard, ensuring safe high-current delivery and reliable performance.
