750mAh 3S LiHV Power for Compact FPV and RC Models
The CNHL Lightning LiHV 750mAh 3S 120C battery occupies a useful middle position between ultra-light micro packs and heavier endurance-focused batteries.
Compared with common 450–550mAh batteries, the 750mAh capacity provides more energy for cinematic passes, cruising, repeated practice laps and mixed indoor-outdoor flying. At approximately 61g, it remains light enough for compatible compact aircraft that would become less responsive with a substantially heavier battery.
The slim 78 × 21 × 22mm case is especially useful on frames with narrow battery channels or forward-loading compartments. The XT30 connection and 16AWG wires support clean installation on small 3S power systems without the weight of a larger connector.
Why Choose This Battery?
-
750mAh capacity: Provides more energy reserve than many 450–650mAh micro packs.
-
Approx. 61g weight: Maintains a practical balance between flight duration and aircraft responsiveness.
-
120C discharge rating: Supports rapid throttle corrections and high-load operation in correctly matched power systems.
-
Slim battery shape: The 78mm-long, 21mm-wide case suits narrow battery channels and compact mounting areas.
-
XT30 connection: Matches lightweight 3S FPV and RC systems using a corresponding XT30 power lead.
-
Flexible charging choice: Can be charged to full LiHV voltage when the complete system supports it or limited to standard 3S LiPo voltage where required.
3S CineWhoop and Micro FPV Battery
This battery is well suited to compatible 2-inch and 2.5-inch CineWhoops that need more flight time than a small 450–650mAh pack but do not have the space or payload allowance for a much larger battery.
The 750mAh capacity favors smooth cinematic cruising, controlled indoor lines and outdoor exploration. Its 120C output also preserves useful throttle response for quick altitude corrections, light freestyle moves and recovery from prop wash.
The additional capacity may produce a steadier, more momentum-focused flight feel than a smaller battery. Pilots who prioritize minimum takeoff weight and very rapid directional changes may prefer a lighter pack, while pilots who want more energy reserve may favor this 750mAh configuration.
BETAFPV Pavo20 Pro and Pro II Battery Option
The CNHL Lightning 750mAh 3S battery can be considered for compatible BETAFPV Pavo20 Pro and Pavo20 Pro II configurations that accept its dimensions, approximately 61g weight and XT30 connector.
The 750mAh capacity suits pilots who prioritize longer cinematic lines and outdoor cruising rather than the lowest possible takeoff weight. Because battery recommendations can vary with the installed video system, camera, frame version and tune, confirm the complete mounting space and final aircraft weight before flying.
Compare this pack with smaller and lighter options in the Pavo20 Pro and Pavo20 Pro II battery collection.
GEPRC CineLog25 V2 and Cinebot25 Fitment
This slim 750mAh pack may also suit compatible GEPRC CineLog25 V2, GEPRC Cinebot25 and similar compact 3S XT30 builds.
Compatibility depends on the exact aircraft version and power-system configuration. Confirm that the model is designed for 3S operation and can securely hold the 78 × 21 × 22mm battery without obstructing the ducts, camera mount, GPS, receiver antenna or other equipment.

750mAh 3S Battery Option for Goosky S2 and S2 Ultra
The CNHL Lightning LiHV 750mAh 11.4V 3S battery is a strong fit candidate for the Goosky S2 and Goosky S2 Ultra. Its 750mAh capacity and approximately 61g weight remain close to the general battery class used by these compact helicopters, while the XT30 connector suits a lightweight high-current power system.
This CNHL pack uses a relatively long and narrow 78 × 21 × 22mm case. It should not be described as a confirmed drop-in replacement until the physical installation has been tested. Check battery insertion depth, canopy clearance, retention, wire direction and center of gravity before flight.
The Goosky power system is normally operated as a standard 3S setup. Unless the specific ESC and helicopter version are confirmed to support the 13.05V maximum of a fully charged 3S LiHV battery, charge this pack only to the standard 3S limit of 12.60V total, or 4.20V per cell.

XT30 Connector Compatibility
This battery includes an XT30 output plug. It connects directly to a corresponding XT30 device-side connector when polarity and orientation are correct.
Models using XT60, EC3, IC3, EC5, IC5, T/Dean, TRX or another connector require an appropriately rated adapter or professional connector conversion.
Keep the power and balance wires clear of propellers, ducts, gears, motor bells, canopy edges and other moving or abrasive parts.
LiHV Charging and Voltage
This battery can be charged to a maximum of 4.35V per cell using a charger with a dedicated 3S LiHV balance-charging mode. A fully charged pack reaches 13.05V.
Full LiHV charging should only be used when the complete aircraft power system supports that voltage. A model described only as “3S compatible” may have been designed around the 12.60V maximum of a standard 3S LiPo battery.
Where full LiHV voltage has not been approved, charge the battery to the standard LiPo limit of 4.20V per cell. This reduces the maximum voltage and available energy but avoids exposing the electronics to an unconfirmed higher input voltage.
The 5C specification is the maximum charge rate. For normal use, a lower balanced charge rate generally creates less heat and places less stress on the cells.

FAQ
Is this a standard LiPo or LiHV battery?
This is a 3S LiHV battery with an 11.4V nominal voltage. It can be charged to 13.05V in LiHV mode when the charger and aircraft electronics support that voltage.
Is 750mAh too large for a 3S CineWhoop?
Not necessarily. It is suitable for compatible aircraft that accept the 78 × 21 × 22mm dimensions and approximately 61g weight. It generally favors flight duration and steady momentum over the lightest possible handling.
Can it be used with the Pavo20 Pro or Pro II?
It can be considered for compatible 3S XT30 configurations when the battery mount accepts its size and weight. Confirm the exact aircraft version and final takeoff weight before use.
Does it fit the Goosky S2 or S2 Ultra?
It is a strong fit candidate based on capacity, weight and connector, but it should not be treated as a confirmed drop-in replacement until battery insertion depth, canopy clearance, wire routing and center of gravity have been checked.
Can I charge it to 13.05V in the Goosky S2?
Only when the specific helicopter electronics are confirmed to support full LiHV voltage. Otherwise, charge the pack to the standard 3S limit of 12.60V.
Can it connect directly to an XT60 model?
No. This battery uses XT30. An appropriately rated XT30-to-XT60 adapter or connector conversion is required, provided the complete connection remains suitable for the current demand.
Should the battery always be charged at 5C?
No. The 5C value is the maximum specified rate, not the required everyday rate. A lower balance-charge rate is generally preferred for routine charging.
Notice
- This is a 3S LiHV battery with a maximum charge voltage of 4.35V per cell.
- Use a compatible balance charger and select the correct 3S LiHV or standard LiPo charge mode.
- Confirm that the aircraft electronics support the selected maximum voltage before charging fully in LiHV mode.
- Check the 78 × 21 × 22mm dimensions, approximately 61g weight and XT30 connector before use.
- Secure the battery firmly and keep the main and balance wires clear of propellers, ducts and moving parts.
- Never charge unattended or use a swollen, punctured, damaged or overheated battery.
- Allow the pack to cool before recharging and use storage mode when it will not be used for an extended period.
- Inspect the battery and cell voltages before the first use and after any hard impact.
