7800mAh Capacity in a 6000mAh-Class Weight Range
The defining advantage of this CNHL Lightning 7800mAh 6S LiHV battery is not capacity alone. It is the relationship between capacity, size and installed weight.
Increasing from 6000mAh to 7800mAh normally means accepting a substantially larger and heavier battery. This pack is designed differently. At approximately 875g and 152 × 51 × 59mm, it remains close to the installation class of many conventional 6000mAh 6S batteries while providing 1800mAh more rated capacity.
That is a 30% capacity increase compared with 6000mAh, creating additional usable energy for longer flights or runs without automatically moving the model into the size and weight class of a conventional high-capacity 7800mAh pack.

Verified for the Freewing Eurofighter Typhoon V2 6S 90mm EDF Jet
The CNHL Lightning LiHV 7800mAh 6S 120C battery with EC5 has been verified for use in the Freewing Eurofighter Typhoon V2 6S 90mm EDF Jet.
This is where the pack's low weight for its capacity becomes especially useful. A conventional 7800mAh battery would often be too large or heavy for a 90mm EDF aircraft, but this Lightning pack remains close to the physical and weight class of the 6000mAh batteries commonly used in large EDF jets.
Moving from 6000mAh to 7800mAh provides 30% more rated capacity while retaining a battery format that has been successfully installed and balanced in the Eurofighter Typhoon V2.
The EC5 output plug also matches the aircraft's EC5 power connection, so no connector adapter is required when the aircraft remains in its standard EC5 configuration.
The additional capacity should not be interpreted as a guaranteed 30% increase in flight time. EDF current draw changes considerably with throttle position, vertical flying, high-alpha maneuvers, wind and external stores. The practical benefit is additional usable energy and landing reserve.
Always confirm the final center of gravity after installation and secure the battery firmly before flight.

High-Capacity Battery Option for the Eflite Pilatus PC 21 1.3m
The CNHL Lightning LiHV 7800mAh 6S 120C is also an interesting high-capacity direction for the Eflite Pilatus PC 21 1.3m, particularly for pilots who prioritize endurance and are comfortable tuning battery position and center of gravity.
The key advantage is that 7800mAh does not automatically mean carrying the weight normally associated with a conventional battery of this capacity. At approximately 875g, this pack stays much closer to the weight class pilots typically consider when experimenting with larger-capacity 6S airplane setups.
For the PC 21, the 7800mAh option should be treated primarily as an endurance-focused setup. A smaller 5000–6000mAh battery can favor lower flying weight and a lighter feel, while 7200–7800mAh options carry more energy for longer mixed-throttle flights.
Before flight, confirm hatch clearance, battery retention, wire routing and final CG. Battery capacity alone does not determine whether a pack is appropriate for the aircraft.
See the complete Eflite Pilatus PC 21 Battery Collection to compare 5000mAh, 6000mAh, 7200mAh and 7800mAh 6S options by capacity, weight and flying style.
Large 6S EDF Jets and RC Airplanes
The lightweight high-capacity format makes this battery especially relevant to large 6S EDF jets and propeller aircraft that normally operate with approximately 5000–6000mAh batteries but have enough physical space and CG adjustment to accept additional capacity.
For aircraft, battery selection should always consider more than capacity. Check battery-bay dimensions, final center of gravity, takeoff weight, ESC maximum voltage, cooling, wire routing and battery retention before moving to a larger pack.
The 120C rating provides substantial current capability, but actual current is determined by the motor, ESC, EDF unit, propeller and operating conditions.
6S RC Cars, Trucks and Boats
The 7800mAh capacity can also provide longer sessions in compatible large RC cars, trucks and boats where the 152 × 51 × 59mm dimensions and approximately 875g weight can be accommodated.
For surface vehicles, additional capacity can reduce the number of battery changes during long bash sessions. The tradeoff is additional chassis mass compared with a smaller 5000–6000mAh pack.
For boats, confirm battery tray dimensions, hatch clearance, hull trim, cooling-line clearance, connector position and secure retention before running.

EC5 and IC5 Connector Compatibility
EC5 and IC5 are physically compatible at the main power connection. This battery can provide normal positive and negative 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 communication, automatic battery identification or Smart battery telemetry.
Models using XT60, XT90, EC3, IC3, TRX or another connector require a correctly rated adapter or professional connector conversion.
LiHV Charging and Maximum Voltage
This is a 6S LiHV battery. When charged in LiHV mode, the maximum voltage is 4.35V per cell, or 26.1V total.
A power system being described as “6S compatible” does not automatically prove that it supports 26.1V. Many conventional 6S systems are designed around the 25.2V maximum voltage of a standard LiPo battery.
Before charging to full LiHV voltage, confirm the ESC manufacturer's maximum input-voltage specification.
If full LiHV support has not been confirmed, this pack can be balance charged to the standard LiPo limit of 4.20V per cell, or 25.2V total. This gives up some usable energy but keeps the battery within conventional 6S LiPo voltage limits.
The 5C specification is the maximum charge rate. A lower balanced charge rate is generally preferred for routine charging because it generates less heat and places less stress on the battery.
About the CNHL Lightning LiHV Series
