Product Overview
The CNHL Lightning LiHV 6700mAh 8S 120C battery is designed for high-power RC applications that demand strong acceleration and stable voltage under load.
The Lightning LiHV chemistry supports charging up to 4.35V per cell, providing improved throttle response and stronger output compared with standard LiPo batteries.
With 8AWG wires and a QS8 connector, this battery is built for extreme current setups used in large EDF jets, helicopters and high-power electric RC platforms.
Applications
- Large EDF jet aircraft
- High-power RC airplanes
- RC helicopters
- Advanced multi-rotor builds
- High-performance RC vehicles using 8S power systems
Single-Pack 8S Option for Freewing Ares 3D EDF Jet
This battery has proven to work well in a single-pack 8S configuration for the Freewing Ares 3D 90mm EDF Jet.
The 120C discharge capability provides strong thrust response and enough reserve power to maintain a stable hover and confidently recover from vertical maneuvers.
It also performs well in other powerful 8S EDF platforms such as the FMS Avanti 90mm.

FAQ
What is an 8S LiPo battery used for?
8S LiPo batteries are typically used in large EDF jets, RC airplanes, helicopters and other high-power electric RC systems that require high voltage.
What are the advantages of LiHV batteries?
LiHV batteries support higher maximum charge voltage compared with standard LiPo batteries, improving throttle response and overall power output.
Why use QS8 connectors?
QS8 connectors are designed for extremely high current loads and are commonly used in powerful RC systems that require reliable high-amperage connections.
What charger should be used for LiHV batteries?
Use a LiHV-compatible balance charger capable of charging to 4.35V per cell.
Notice
- Ensure voltage and connector compatibility before use.
- Do not charge above 4.35V per cell.
- Inspect battery condition before first use.
- If the battery does not hold charge initially, cycle it several times using a balance charger.
