Quick Fit Check
The CNHL Lightning LiHV 6000mAh 15.2V 4S 120C HV LiPo Battery with EC5 Plug is a high-output 4S battery for RC users who want substantial capacity, strong voltage support, and an EC5 connector without moving into an excessively bulky pack. Its 6000mAh capacity makes it useful for larger RC airplanes, performance boats, 1/8-scale vehicles, and dual-battery 8S aircraft setups where runtime, power delivery, and installed weight must be balanced carefully.
Before ordering, confirm that your model supports 4S LiPo or LiHV power, has enough battery space for a 149 × 51 × 31mm pack, can safely carry an approximately 477g battery, and uses an EC5 connector or a properly rated alternative. For dual-4S aircraft, use two identical packs and confirm the total installed weight, series wiring, connector clearance, ESC voltage limit, and final center of gravity.

Core Description
The CNHL Lightning LiHV 6000mAh 4S 120C battery is designed for RC platforms that need more capacity than a common 5000mAh pack while retaining strong discharge support and a manageable physical profile. The 6000mAh capacity provides useful energy reserve for longer flights, extended boat runs, and larger surface vehicles, while the 120C rating supports repeated throttle changes and high-load acceleration.
LiHV chemistry adds another performance dimension. When charged correctly in LiHV mode with a compatible charger, the pack can deliver a stronger early-run voltage feel than a standard 4S LiPo of similar capacity. That can be useful in aircraft takeoff and climb, boat acceleration, large-vehicle launches, and dual-pack EDF systems where voltage stability under load matters.
The EC5 plug and 10AWG wiring make this battery relevant for higher-current RC systems. EC5 and IC5 are often searched together in ARRMA, Spektrum, Horizon Hobby, aircraft, and boat applications, but this battery is not a Spektrum Smart battery and does not provide Smart battery telemetry.
Why Choose a 6000mAh 4S LiHV Battery?
A 6000mAh 4S LiHV battery occupies a useful position between lighter 5000mAh packs and much larger long-runtime batteries. It adds 20% rated capacity over a 5000mAh pack while remaining compact enough for many large airplanes, performance boats, and 1/8-scale vehicles.
Compared with a lighter pack, the 6000mAh capacity can provide longer usable sessions and more reserve energy. The tradeoff is additional weight, so battery selection should never be based on capacity alone. Aircraft pilots should check center of gravity and landing behavior, boat users should check hull trim and self-righting performance, and vehicle owners should confirm tray fitment and chassis balance.
The high-discharge Lightning LiHV construction also makes this pack relevant where a standard long-runtime battery may feel soft under load. It is intended for users who want capacity without giving up strong throttle response and high-current capability.
RC Airplane and Warbird Applications
This battery can be considered for larger 1.5m–1.7m RC airplanes, sport aircraft, warbirds, bush planes, and other 4S platforms where battery dimensions, installed mass, connector type, and center of gravity are suitable.
For warbird applications, it is featured as a battery direction for the Nexa Messerschmitt BF-109 1540mm ARF. A 6000mAh pack may provide additional flight time, but users should confirm that the aircraft can accommodate the 477g weight without becoming excessively nose-heavy.
For bush and utility flying, it can also be considered for models such as the Avios Grand Tundra V2. In STOL-style aircraft, battery weight and position affect low-speed behavior, takeoff distance, landing feel, and overall wing loading, so CG verification remains essential.
Performance RC Boat Applications
The combination of 6000mAh capacity, 120C discharge support, EC5 connector, and 10AWG wiring also makes this battery relevant for high-performance 4S boats and dual-4S 8S marine systems. In boat use, the pack offers a balance between runtime and strong acceleration, but the added capacity must still be matched to the hull’s battery trays and weight distribution.
It can be considered for large boats such as the Pro Boat Super Sonicwake 48" when battery dimensions, connector layout, tray size, secure retention, and the boat’s approved voltage configuration are suitable. Depending on the specific setup, larger battery trays or changes to battery positioning may be required.
For dual-battery boats, use two identical packs with the same capacity, connector, age, condition, internal resistance, and charge level. Install both batteries symmetrically and test hull attitude, turning behavior, cooling, and self-righting performance before extended full-throttle operation.
Lightweight Dual-4S Setup for the Freewing Eurofighter Typhoon V2 8S
Use two matching CNHL Lightning LiHV 6000mAh 15.2V 4S 120C batteries with EC5 plugs in series for the Freewing Eurofighter Typhoon V2 8S High Performance 90mm EDF Jet when the aircraft, wiring, ESC voltage limit, and battery compartment have been verified for this setup.
Two 4S 6000mAh batteries connected in series create an 8S 6000mAh battery system. Series wiring doubles voltage while capacity remains 6000mAh; it does not create a 12000mAh system. The two-pack combination weighs approximately 954g before accounting for the series harness and retention hardware.
Compared with a typical dual-5000mAh arrangement, this pair increases rated capacity by 20%. It is intended as an endurance-focused alternative for pilots who want more energy reserve while keeping pack weight under control. This matters in a dual-battery EDF because every increase in individual pack weight is carried twice.
See more battery options for the Freewing Eurofighter Typhoon V2 6S and 8S.
Dual-4S Battery Option for the Freewing Ares 3D 90mm EDF
Two matching packs can also be connected in series to create an 8S 6000mAh setup for compatible high-power EDF aircraft such as the Freewing Ares 3D 90mm EDF Jet.
Before using a dual-4S setup, confirm the aircraft’s required cell count, ESC maximum input voltage, battery compartment dimensions, connector arrangement, cooling, installed weight, and center of gravity. Do not assume that a battery will fit only because the total cell count matches.
EC5 Plug and IC5 Search Compatibility Notes
This battery comes with an EC5 plug, a high-current connector commonly used in large RC aircraft, boats, trucks, truggies, and dual-battery systems. EC5 and IC5 are frequently searched together because they appear in similar ARRMA, Spektrum, Horizon Hobby, and high-current RC applications.
This is not a Spektrum Smart battery and does not provide Smart battery data. For an IC5-equipped system, confirm physical connector fit, polarity, current rating, charging method, wire clearance, and whether the model expects Smart battery communication before use.

FAQ
What is this 6000mAh 4S LiHV battery best used for?
It is best used in larger 4S airplanes, performance boats, 1/8-scale vehicles, and supported dual-4S 8S aircraft or marine setups that need additional capacity and strong current delivery.
Can two of these 4S batteries create an 8S setup?
Yes. Two identical 4S 6000mAh packs connected in series create an 8S 6000mAh system. Voltage doubles, but capacity remains 6000mAh.
Can these batteries work in the Freewing Eurofighter Typhoon V2 8S?
They can be considered as a dual-4S endurance-focused option when the battery bays, combined weight, EC5 series wiring, ESC maximum input voltage, cooling, and final center of gravity are all confirmed before flight.
Why choose 6000mAh instead of 5000mAh?
A 6000mAh pack provides 20% more rated capacity than a 5000mAh pack. The tradeoff is additional weight, so it is best for models that can carry the extra mass without compromising balance or handling.
Can this battery be used in the Pro Boat Super Sonicwake 48?
It can be considered for compatible Super Sonicwake 48 setups when the battery trays, connector layout, approved voltage system, secure retention, and hull balance are suitable.
What is the advantage of LiHV chemistry?
LiHV chemistry supports a higher per-cell charging mode when used with a compatible charger. This can provide a stronger early-run voltage feel and more energetic throttle response than a standard LiPo of similar size.
Can I charge this battery with a standard LiPo charger?
Use LiHV mode only when the charger specifically supports LiHV batteries. When charging conservatively as a standard LiPo pack, do not exceed standard LiPo voltage limits.
Is EC5 the same as IC5?
No. EC5 and IC5 are commonly searched together because they appear in similar high-current RC systems, but this battery has an EC5 plug and does not provide Spektrum Smart battery data.
Notice
