The CNHL Lightning LiHV 6700mAh 22.8V 6S 120C HV LiPo Battery with EC5 Plug is a high-capacity performance 6S LiHV battery for RC pilots and drivers who want longer runtime, strong voltage support, and high-current output in demanding 6S systems. With 6700mAh capacity, 22.8V 6S LiHV voltage, 120C continuous discharge output, 10AWG wire, and an EC5 plug, this pack is a strong option for EDF jets, RC airplanes, helicopters, ARRMA 6S vehicles, and high-load 6S setups where tray size and weight balance allow.
This battery is best used when your model supports 6S LiHV power, has enough battery space for a 150 × 49 × 51mm pack, can safely handle an approximately 758g battery, and uses an EC5 connector or a compatible high-current setup. EC5 and IC5 are commonly searched together in larger RC power systems, but this battery does not provide Spektrum Smart battery data.

Core Description
The CNHL Lightning LiHV 6700mAh 6S 120C HV LiPo battery is designed for RC setups that need more usable capacity without giving up strong output. The 6700mAh capacity makes it attractive for pilots and drivers who want longer flight or run sessions, while the 120C discharge rating helps support demanding power systems under load.
The LiHV chemistry is part of the performance appeal. When charged correctly in LiHV mode with a compatible charger, this pack can provide a sharper early-run voltage feel than a standard 6S LiPo of similar size. That can be useful in EDF jets, helicopters, high-performance airplanes, and 6S surface vehicles where throttle response and voltage consistency are noticeable.
The 10AWG wire and EC5 plug make this pack suitable for high-current 6S systems. EC5 is commonly used in EDF jets, larger RC aircraft, helicopters, ARRMA 6S vehicles, and other performance platforms. IC5 users often search for similar battery options, but this pack is not a Spektrum Smart battery and does not provide Smart battery telemetry.
High-Capacity Battery Option for the Freewing JL-8 80mm EDF
The CNHL Lightning LiHV 6700mAh 22.8V 6S 120C HV LiPo Battery with EC5 Plug is a high-capacity option for the Freewing PLAAF JL-8 80mm EDF Jet. Despite its 6700mAh capacity, the pack weighs approximately 758g, keeping it in a practical range for pilots who want additional usable capacity without moving into an excessively heavy 6S setup.
For the JL-8, this pack should be positioned as the longer-flight / high-capacity option rather than the lightest sport setup. Compared with a 4000mAh 6S pack, it adds weight but can extend flight time. Compared with many very large 6S packs, it remains reasonable for an 80mm EDF when dimensions, installed mass, and center of gravity are confirmed carefully.
Because this pack is above Freewing's published 6000mAh capacity recommendation, always verify battery-compartment fit, secure mounting, approved system voltage, intake and wire clearance, ESC cooling, takeoff weight, and the specified 78mm center of gravity before flight. Explore the full range in our Freewing JL-8 battery collection.
Applications for EDF Jets, Aircraft, Helicopters, and RC Cars
This 6700mAh 6S LiHV battery is best suited for mid-to-large RC aircraft and high-performance vehicles where voltage stability, capacity, and current delivery all matter. It is especially useful when a 5000mAh pack feels too short on runtime, but the model still needs strong 6S output and an EC5 connector.
In RC airplanes and EDF jets, this pack can be considered for models such as the HobbyKing Sports Hawk, E-flite Turbo Timber SWS, Freewing Zeus, FMS F-86 Sabre 80mm, and XFLY T-7A Red Hawk when battery bay size, center of gravity, connector, ESC rating, and takeoff weight are suitable.
It also performs well as a candidate pack for the Freewing A-10 V3 Thunderbolt II RC Jet, where twin-EDF setups benefit from stable voltage delivery and strong discharge support. For twin-EDF aircraft, always check CG, total installed battery mass, ESC temperature, airflow, and landing approach behavior before regular flying.
For helicopter pilots, this pack can be considered for models such as the T-Rex 550, Goblin Kraken 580, and XLPower Specter 700 V2 when the tray, strap system, connector, current demand, and flying style are suitable. Aggressive 3D flying may require careful temperature and voltage-sag monitoring during early flights.
Compatible RC Cars: ARRMA Kraton 6S and 1/8 Bashers
This battery can also be used in high-power 6S RC cars such as the ARRMA Kraton 6S series when tray size, connector setup, battery retention, and ESC requirements match. The 6700mAh capacity is useful for longer bashing sessions, while the 120C discharge output supports strong acceleration and repeated high-load bursts.
The EC5 connector makes this pack relevant for many ARRMA-style IC5 / EC5 power systems, but this is not a Spektrum Smart battery and does not provide Smart battery data. If your vehicle uses an IC5-equipped ESC, confirm physical connector fit, polarity, wire clearance, and charger setup before use.
The compact form factor allows this battery to run as a single 6S pack in suitable 1/8 scale bashers, or as part of a compatible dual-battery configuration only when the vehicle is specifically designed for that setup. If you are looking for a full setup guide, explore the ARRMA Kraton 6S battery guide.
Why Choose a 6700mAh 6S LiHV Battery?
A 6700mAh 6S LiHV battery makes sense when you want more runtime than common 4000mAh or 5000mAh packs while still keeping strong discharge performance. It is a good direction for larger EDF jets, 6S sport aircraft, helicopters, and 1/8 bashers where the model can physically and safely carry the extra capacity.
Compared with a lighter 4000mAh pack, this 6700mAh battery gives more energy reserve and longer usable sessions. Compared with extremely large 6S packs, it stays in a more practical size and weight class for many performance models. The key is not capacity alone; the model must still balance correctly and keep the power system cool.

EC5 Plug and IC5 Search Compatibility Notes
This battery comes with an EC5 plug, a connector type commonly used in larger RC aircraft, EDF jets, helicopters, boats, and 6S surface vehicles. EC5 and IC5 are often searched together because they appear in similar ARRMA, Spektrum, and high-current RC power-system discussions.
This battery is not a Spektrum Smart battery and does not provide Smart battery data. If your model uses an IC5-equipped ESC, confirm physical connector fit, polarity, current rating, wire clearance, and charging setup before use.

What to Check Before Buying
-
Voltage: Your model must support 6S LiHV / 22.8V battery operation.
-
Connector: This battery uses an EC5 plug. EC5 and IC5 are commonly searched together, but this is not a Spektrum Smart battery.
-
Battery size: Confirm your battery tray or bay can fit 150 × 49 × 51mm.
-
Weight: At approximately 758g, check aircraft CG, EDF takeoff weight, helicopter tray balance, car handling, or boat trim before use.

FAQ
What is this 6700mAh 6S LiHV battery best used for?
It is best used in EDF jets, larger 6S aircraft, helicopters, ARRMA 6S vehicles, and high-performance 6S setups that need more capacity, strong discharge output, and EC5 connector support.
Can this battery work in the Freewing JL-8 80mm EDF?
Yes, it can be considered as a high-capacity option for the Freewing JL-8 80mm EDF, but it is above the published 6000mAh capacity recommendation. Confirm battery fitment, secure mounting, ESC temperature, takeoff weight, and the specified 78mm CG before flight.
Can this battery run an ARRMA Kraton 6S?
Yes, it can be used in ARRMA Kraton 6S-style vehicles when tray size, EC5 / IC5-style connector fitment, battery retention, ESC rating, and vehicle setup are suitable.
Why choose 6700mAh instead of 5000mAh?
A 6700mAh pack can provide longer runtime and more energy reserve than a 5000mAh pack. The tradeoff is added size and weight, so CG, handling, cooling, and battery retention must be checked carefully.
What is the main advantage of a LiHV battery?
LiHV chemistry supports a higher per-cell charging mode when used with a compatible LiHV charger. In practical RC use, that can give stronger early-run response and more energetic throttle behavior compared with a standard 6S LiPo of similar size.
What charger should be used for LiHV batteries?
Use a balance charger that supports LiHV charging. If charging conservatively as a standard LiPo battery, do not exceed standard LiPo voltage limits. Never use an unsupported or incorrect charging mode.
Is EC5 compatible with IC5 systems?
EC5 and IC5 are often searched together because they appear in similar high-current RC systems, but this battery has an EC5 plug and does not include Spektrum Smart battery data. Always confirm physical connector fit, polarity, and charging setup.
Notice
