Quick Fit Check
The [Combo] 2 Packs CNHL MiniStar 850mAh 14.8V 4S 70C LiPo Battery with XT30U Plug includes two compact, lightweight flight batteries for 2.5-inch cinewhoops, small freestyle drones and other 4S FPV platforms designed around the 700–850mAh battery class.
Each battery measures 62 × 33 × 30mm and weighs approximately 110g. The combination of 850mAh capacity, 70C continuous output and an XT30U connector makes these packs suitable for pilots who want more flight time than a smaller 650–750mAh battery without moving to a substantially heavier 1000mAh-class pack.
Before ordering, confirm the battery compartment or mounting plate, strap length, XT30U connection, cable routing and acceptable takeoff weight for your aircraft.

Compact 850mAh 4S Power for CineWhoops and FPV Drones
The CNHL MiniStar 850mAh 4S 70C LiPo battery is designed for compact FPV aircraft where battery weight, dimensions and center of gravity directly affect handling.
At approximately 110g per pack, it provides more capacity than many lightweight 650–750mAh batteries while remaining suitable for compatible 2.5-inch cinewhoops and compact freestyle platforms.
The 70C continuous and 140C burst ratings support responsive throttle changes, controlled punch-outs and sustained 4S operation in correctly matched power systems. The 850mAh capacity is especially useful for pilots who prioritize smooth cruising, cinematic movement and energy reserve rather than the lightest possible setup.
Why Choose the Two-Pack Combo?
-
Two flight-ready batteries: Complete one flight, replace the pack and return to the air without waiting for the first battery to recharge.
-
Consistent matching specification: Both packs use the same capacity, voltage, dimensions, discharge rating and connector.
-
Useful field rotation: Alternate between batteries to reduce the pressure to recharge a warm pack immediately after landing.
-
850mAh capacity: Provides a practical balance between flight duration and installed weight for compatible cinewhoops.
-
XT30U connection: Suits compact FPV systems designed around XT30U or corresponding compatible power leads.
-
Standard 4S voltage: Charges to 16.8V and does not require LiHV charging mode.
850mAh 4S Battery for the GEPRC DarkStar25 O4 Pro
The CNHL MiniStar 850mAh 14.8V 4S 70C LiPo Battery with XT30U is a practical standard-voltage option for the GEPRC DarkStar25 O4 Pro, O4 Wide and compatible DarkStar25 builds.
Its 850mAh capacity sits at the upper end of the DarkStar25 battery range, making it well suited to cinematic cruising, outdoor exploration and pilots who prefer a more planted flight feel with additional energy reserve.
The XT30U battery plug connects directly to the DarkStar25 XT30U-M power lead without an adapter. Each battery weighs approximately 110g, so the aircraft will carry more momentum than it would with a lighter 700–750mAh pack. This can support smoother lines and steadier cruising, while rapid directional changes may feel less immediate.
Always confirm battery clearance, strap tension, cable routing and final takeoff weight before flying.
Compare both compatible options in our best battery collection for the GEPRC DarkStar25 O4 Pro.
GEPRC CineLog Battery Option
This 850mAh 4S battery can be used with compatible models in the GEPRC CineLog series that accept its 62 × 33 × 30mm dimensions, approximately 110g weight and XT30U connection.
The capacity supports smooth indoor-to-outdoor cinematic flying, moderate cruising and repeated controlled throttle changes. Compared with a smaller battery, the 850mAh pack can provide more energy reserve, although the additional weight may produce a more settled rather than highly agile flight response.

GEPRC Cinebot25 V2 O4 Pro Battery
The CNHL MiniStar 850mAh pack is also an option for compatible GEPRC Cinebot25 V2 O4 Pro builds where the pilot wants more capacity than a lightweight 4S pack.
Its 110g weight favors smooth momentum, stable cinematic movement and outdoor cruising. Pilots prioritizing the lightest possible takeoff weight or faster directional response may prefer a lower-capacity option.

More Compatible FPV and RC Applications
2.5-Inch CineWhoops
This battery is well suited to compatible 2.5-inch cinewhoops that use a 4S power system, XT30U connection and a battery mount large enough for its dimensions. The 850mAh capacity supports cinematic cruising and mixed indoor-outdoor use.
150mm to 210mm FPV Drones
Compact freestyle and cruising builds in this size range may use the pack when the frame, motor setup and center of gravity support its approximately 110g weight.
Small Freestyle Builds
The 70C discharge rating supports responsive 4S performance in correctly matched small freestyle platforms. Confirm motor current, propeller choice and battery temperature during the first flights.
Durafly MFX Racer
The compact battery format may also suit the Durafly MFX Racer and other small 4S RC airplanes that accept the dimensions, weight and XT30U connection. Secure the pack properly and verify the specified center of gravity before flight.

The better choice depends on the aircraft, payload, tune and intended flight style. The 850mAh pack is not automatically better simply because it has more capacity.
XT30U Connector
Each battery includes an XT30U output plug. It connects directly to a corresponding XT30U-M power lead when connector orientation and polarity are correct.
No adapter is required for the GEPRC DarkStar25 XT30U-M connection. Models using XT60, EC3, IC3, EC5, IC5, T/Dean, TRX or another connector require a correctly rated adapter or professional connector conversion.
Keep the connector and power wires clear of propellers, ducts, frame edges and other moving or abrasive parts.

FAQ
Does this battery fit the GEPRC DarkStar25 O4 Pro?
Yes. The 850mAh capacity is within the DarkStar25 battery range, and the XT30U connector connects directly to the aircraft’s XT30U-M lead. Confirm battery restraint and final takeoff weight before flying.
Is 850mAh suitable for a 2.5-inch cinewhoop?
It can be suitable when the aircraft accepts the 62 × 33 × 30mm dimensions and approximately 110g weight. It generally favors flight time and smooth momentum over the lightest possible handling.
Is this a standard LiPo or LiHV battery?
This is a standard 4S LiPo battery. Its nominal voltage is 14.8V, and its maximum balanced charge voltage is 16.8V, or 4.20V per cell.
Can it connect directly to an XT60 model?
No. This battery uses XT30U. A correctly rated XT30-to-XT60 adapter or connector conversion is required for an XT60-equipped model, provided the current demand remains suitable for the complete connection system.
Should these batteries always be charged at 5C?
No. The 5C specification is the maximum charge rate, not the required everyday rate. A lower balanced charge rate generally creates less heat and places less stress on the cells.
Notice
- Each battery is a standard 4S LiPo pack with a maximum charge voltage of 4.20V per cell.
- Charge each battery with a compatible LiPo balance charger using the correct four-cell setting.
- Confirm the 62 × 33 × 30mm dimensions, approximately 110g weight and XT30U connector before use.
- The package contains two separate batteries; do not connect them in series or parallel unless the complete system is designed for that configuration.
- Secure the battery firmly and keep the wires clear of propellers, ducts, frame edges and moving parts.
- Inspect both batteries independently before charging and use.
- Never charge unattended, and do not use a swollen, punctured, damaged or overheated battery.
- Allow each pack to cool before recharging and use storage mode when the batteries will not be used for an extended period.
