6700mAh Capacity at Only About 758g
The main strength of this CNHL Lightning 6700mAh 6S LiHV battery is its capacity-to-weight balance.
At approximately 758g, it carries considerably more capacity than many conventional 5000–5200mAh batteries without moving into the weight class of very large 7000–8000mAh packs. That makes it particularly attractive to aircraft and helicopters where extra battery energy is useful but every additional gram affects center of gravity, rotor loading or takeoff weight.
The 6700mAh capacity provides 34% more rated capacity than 5000mAh and approximately 29% more than 5200mAh. Actual flight or driving-time improvement will depend on power demand, throttle use, gearing, rotor speed and operating conditions.

A Strong 6S Battery Option for the SAB ILGoblin Piuma 700
The CNHL Lightning LiHV 6700mAh 6S 120C is particularly well suited to the SAB ILGoblin Piuma 700 because the helicopter can be configured around either a 6S or 12S power system.
For a properly configured 6S Piuma, one 6700mAh pack provides a simple single-battery setup with substantial energy reserve. The approximately 758g battery weight also keeps the pack in a more practical range for a performance 700-class helicopter than many very high-capacity 6S alternatives.
Real-world use of this battery in a 6S Piuma has shown why the capacity is attractive: compared with a smaller previous setup, the 6700mAh pack allowed a noticeably longer usable flight window while helping the helicopter maintain head speed further into the flight. Exact results depend on rotor speed, collective pitch, governor settings and flying style, so the benefit should be understood as additional usable energy rather than a guaranteed fixed flight time.
For a 12S Piuma, two matching 6700mAh 6S batteries may be used in series when the motor, ESC and wiring are designed for that configuration.

Series connection doubles voltage but does not double capacity. Two 6700mAh batteries in series remain a 6700mAh system.
For 12S use, also remember that two fully charged 6S LiHV packs can produce up to 52.2V. Confirm the ESC's maximum input voltage before using full 4.35V-per-cell LiHV charging.
Some Piuma installations may use a different battery-tray or connector arrangement, so verify the actual wiring fitted to the helicopter before connecting an EC5 battery.

High-Capacity Option for the Freewing JL-8 80mm EDF
The CNHL Lightning 6700mAh 6S LiHV can also be considered as a high-capacity option for the Freewing PLAAF JL-8 80mm EDF Jet.
The important point is that 6700mAh sits above the aircraft's published 6000mAh battery recommendation. It should therefore be viewed as an endurance-oriented alternative rather than the default JL-8 battery.
Its approximately 758g weight helps make the capacity more practical than many conventional 6700mAh-class packs, but battery-bay fit, final takeoff weight and center of gravity remain more important than capacity alone.
Confirm the battery compartment, secure retention, wire and intake clearance, ESC cooling and the specified 78mm CG before flight.
Compare standard and higher-capacity options in the Freewing JL-8 Battery Collection.
Freewing A-10 V3 Battery Selection Note
This 6700mAh battery may also attract interest from pilots of the Freewing A-10 V3 Thunderbolt II because the aircraft uses a powerful 6S twin-EDF system.
However, 6700mAh should be treated as a high-capacity alternative, not an automatic drop-in recommendation. Twin-EDF aircraft are particularly sensitive to battery mass because additional weight affects takeoff roll, landing speed, flare behavior and center of gravity.
If considering this pack, confirm battery dimensions, total installed weight, CG, wire routing and ESC temperature before regular use.

6S Helicopter Applications
The combination of approximately 758g weight, 6700mAh capacity and high discharge capability makes this pack particularly interesting for larger electric helicopters configured around 6S.
Potential applications include suitable builds based on platforms such as the T-Rex 550, Goblin Kraken 580 and other helicopters where the tray, strap arrangement, connector and center of gravity can accommodate the pack.
For high-head-speed or aggressive 3D use, monitor battery, motor and ESC temperatures during initial flights. Capacity and C rating alone do not determine whether a battery is optimal for a particular rotor speed and gearing combination.
ARRMA Kraton 6S and Large RC Basher Applications
The 6700mAh capacity is also attractive to compatible ARRMA Kraton 6S and other 1/8-scale basher setups where longer running sessions are preferred.
At approximately 150mm long, the battery is relatively compact for its capacity, but actual fit depends on the specific Kraton generation, tray configuration, battery straps and surrounding wiring.
The EC5 connector is physically compatible with the main power contacts of an IC5-equipped vehicle. This battery provides normal main power but does not include Spektrum Smart battery electronics or data communication.
Compared with a 5000–5200mAh battery, the 6700mAh capacity provides more energy but also changes vehicle mass and inertia. Drivers prioritizing agile handling may still prefer a smaller battery.
See more appropriately sized single-6S and dual-3S options in the ARRMA Kraton 6S Battery Collection.

EC5 and IC5 Connector Compatibility
EC5 and IC5 are physically compatible at the main positive and negative power connection. This CNHL battery can therefore supply normal power through a corresponding IC5 device-side connector when polarity and orientation are correct.
This is a conventional CNHL EC5 battery and does not provide Spektrum Smart battery identification, automatic charging information or battery telemetry.
Models using XT60, XT90, EC3, IC3, TRX or another connector system require an appropriately rated adapter or professional connector conversion.
LiHV Charging and Maximum Voltage
This is a 6S LiHV battery. A full LiHV charge reaches 4.35V per cell, or 26.1V total.
A model being described as “6S compatible” does not automatically prove that its ESC supports 26.1V. Many conventional 6S systems are designed around the 25.2V maximum voltage of a standard LiPo battery.
Before using full LiHV charging, confirm the ESC manufacturer's maximum input-voltage specification.
If full LiHV compatibility has not been confirmed, the battery can be balance charged to the standard LiPo limit of 4.20V per cell, or 25.2V total.
The 5C specification is the maximum charge rate. For routine charging, a balanced 1C charge rate is preferred when charging speed is not the priority.
