Freewing F-35C 110mm Battery Requirements
The Freewing F-35C Lightning II uses a 12S power system built from two matching 6S battery packs. This layout is especially convenient for EDF pilots who already use 6S batteries in other large electric aircraft and want to keep the same battery format across multiple models.
| Aircraft | Freewing F-35C Lightning II 110mm EDF |
| Power System | 12S |
| Battery Configuration | 2 × matching 6S batteries |
| Freewing Capacity Range | 5000–6000mAh per 6S pack |
| Practical Extended Option | 6200mAh 6S |
| Connector | EC5 |
| CG Range | 133–140mm from the leading edge where the removable wing panel meets the fuselage |
Always use two packs of the same model, capacity, chemistry and similar age and condition. Both packs should start the flight at the same state of charge and should be treated as one matched 12S battery set.
Which Battery Capacity Is Best for the Freewing F-35C?
The best battery capacity depends on how you want to balance weight, available energy, discharge headroom and overall flight setup. The F-35C can use several CNHL battery sizes effectively, so there is room to choose between a factory-style setup and higher-capacity alternatives.
| Capacity Class | Positioning | Best For |
|---|---|---|
| 5000–5200mAh | Closest to the lower end of the standard setup | Pilots who want a conventional 12S EDF configuration |
| 6000mAh | Within Freewing's recommended capacity range | A strong all-round starting point for the F-35C |
| 6200mAh | A small step above the standard 6000mAh class | Pilots wanting slightly more usable capacity |
| 6700–9500mAh | Higher-capacity confirmed-fit options | Capacity-focused setups with careful final CG adjustment |
Confirmed CNHL LiPo Options for the Freewing F-35C 110mm
The following CNHL standard LiPo batteries have suitable dimensions and installed weight for the Freewing F-35C 110mm. The aircraft uses two matching packs at a time to create the required 12S system.
| CNHL Series | Capacity | Voltage | Discharge Rate | Connector |
|---|---|---|---|---|
| Black Series | 5000mAh | 22.2V 6S | 40C / 65C | EC5 |
| G+Plus | 5000mAh | 22.2V 6S | 70C / 100C | EC5 |
| Racing Series | 5200mAh | 22.2V 6S | 90C | EC5 |
| Black Series | 6000mAh | 22.2V 6S | 65C | EC5 |
| G+Plus | 6000mAh | 22.2V 6S | 70C / 100C | EC5 |
| Racing Series | 6200mAh | 22.2V 6S | 90C | EC5 |
| Racing Series | 9500mAh | 22.2V 6S | 90C | EC5 |
CNHL Lightning LiHV Batteries for the Freewing F-35C
The Freewing F-35C power system also supports suitable 6S LiHV batteries. CNHL Lightning LiHV packs use a 22.8V nominal voltage and can be charged to the LiHV full-charge voltage of up to 4.35V per cell when used with a LiHV-compatible charger.
Two matching 6S Lightning LiHV packs form the aircraft's 12S LiHV setup. This gives pilots a higher-voltage alternative to conventional 22.2V 6S LiPo packs while keeping the same two-pack battery layout and EC5 connector format.
| Battery | Voltage | Discharge Rate | Connector |
|---|---|---|---|
| Lightning LiHV 5500mAh | 22.8V 6S | 120C | EC5 |
| Lightning LiHV 6000mAh | 22.8V 6S | 120C | EC5 |
| Lightning LiHV 6700mAh | 22.8V 6S | 120C | EC5 |
| Lightning LiHV 7200mAh | 22.8V 6S | 120C | EC5 |
| Lightning LiHV 7800mAh | 22.8V 6S | 120C | EC5 |
| Lightning LiHV 8500mAh | 22.8V 6S | 120C | EC5 |
Use LiHV mode only with a charger that specifically supports LiHV chemistry. Do not charge a LiHV pack beyond 4.35V per cell.
5000mAh vs 6000mAh vs 6200mAh for the Freewing F-35C
5000–5200mAh: Stay Close to the Standard Setup
A pair of 5000–5200mAh 6S packs keeps the aircraft close to the lower end of Freewing's intended battery range. This is a sensible choice for pilots who prefer a lighter, more conventional 12S EDF setup.
6000mAh: The Natural All-Round Choice
6000mAh sits directly within Freewing's recommended range and is one of the most balanced choices for the F-35C. It offers more stored energy than a 5000mAh setup while staying close to the aircraft's intended battery configuration.
6200mAh: More Capacity Without a Large Jump
6200mAh moves only slightly beyond the standard 6000mAh class and remains a very practical option for the F-35C. The CNHL Racing Series 6200mAh 6S 90C EC5 is a good fit for pilots who want a modest increase in available capacity without moving into a much larger battery class.
Higher-Capacity Batteries for the Freewing F-35C
The F-35C can also accommodate several higher-capacity CNHL batteries beyond the standard 5000–6200mAh range. Confirmed-fit options include 6700mAh, 7200mAh, 7800mAh and 8500mAh Lightning LiHV packs, as well as the 9500mAh Racing Series LiPo.
Higher capacity provides more stored energy, but it should not be translated directly into a guaranteed number of extra flight minutes. EDF current draw changes significantly with throttle use, and larger packs can also change the final balance point. Always treat capacity, installed weight and CG as parts of the same setup decision.
Freewing F-35C CG and Battery Placement
Do not rely on a fixed battery-tray position to determine the CG. Different pack lengths, capacities and weight distributions can move the aircraft's balance point even when every battery physically fits the bay.
Freewing specifies a CG range of 133–140mm, measured from the leading edge at the point where the removable wing panel meets the fuselage. This measurement should be the final reference for battery positioning.
Install and secure both 6S packs, check the aircraft at the specified CG point, and move the battery pair forward or rearward as required before flight.
Why Matching Two 6S Packs Matters on a 12S EDF Jet
When two 6S batteries operate together as one 12S system, they should be treated as a matched pair. Avoid combining different capacities, different battery chemistries, substantially different ages or packs with noticeably different condition.
- Use the same CNHL battery model for both sides of the 12S set.
- Charge both packs fully before the flight.
- Use packs with similar cycle history and condition.
- Do not mix standard LiPo and LiHV packs in the same 12S set.
- Check both packs after each flight rather than monitoring only one.
EC5 Batteries for the Freewing F-35C
The Freewing F-35C uses EC5 for its recommended battery setup, and the CNHL batteries listed in this collection are offered with EC5 plugs. This keeps the installation straightforward and avoids adding an unnecessary connector conversion to a high-current 12S EDF power system.
Freewing F-35C Flight Time and Battery Capacity
A 3.5-minute timer is a sensible conservative starting point for a 5000mAh setup, with total flight time often extending beyond that depending on throttle use and landing preparation. Moving to 6000mAh or 6200mAh provides more available energy, but there is no fixed runtime that applies to every pilot.
Full-power passes, vertical climbs and repeated acceleration consume energy much faster than reduced-throttle cruising and glide segments. Start with a conservative timer, check both batteries after landing and gradually build a flight-time reference that matches your own flying style.
Freewing F-35C Battery FAQ
What battery does the Freewing F-35C 110mm use?
The F-35C uses two matching 6S batteries together to create a 12S power system. Freewing specifies 5000–6000mAh LiPo packs, while 6200mAh is also a practical verified capacity for the airframe.
Can I use 6000mAh 6S batteries in the Freewing F-35C?
Yes. 6000mAh 6S is within Freewing's recommended capacity range and is one of the strongest all-round battery sizes for the aircraft.
Can I use 6200mAh batteries?
Yes. The CNHL Racing Series 6200mAh 6S 90C EC5 has suitable dimensions and weight for the F-35C and offers a modest capacity increase over a standard 6000mAh setup.
Can the Freewing F-35C use LiHV batteries?
Yes. Suitable CNHL Lightning 6S LiHV packs can be used as matched pairs in the F-35C's 12S system. Use a charger that supports LiHV mode and never exceed 4.35V per cell.
Can I use batteries larger than 6200mAh?
Yes. The higher-capacity CNHL batteries shown in this collection have suitable dimensions and installed weight for the F-35C. Final battery position should still be adjusted to achieve the correct 133–140mm CG.
Can I use one 5000mAh pack and one 6000mAh pack together?
No. The two 6S batteries should be matching packs of the same model, chemistry and capacity, with similar age and condition.
Where should the batteries sit in the tray?
There is no universal tray position that should be copied for every battery size. Install and secure both packs, then move them forward or rearward until the aircraft balances within Freewing's specified 133–140mm CG range.
