Compact 1800mAh 4S Power for High-Performance RC Aircraft
The CNHL MiniStar 1800mAh 4S 120C is aimed at models that need the additional voltage of a 4S power system without carrying the size and weight of a large-capacity battery.
Its approximately 209g weight makes the pack especially relevant to compact speed aircraft, FPV airplanes and other performance-focused models where battery mass directly affects acceleration, center of gravity and control response.
The 120C continuous and 240C burst ratings provide substantial stated discharge capability for high-load brushless systems. Actual current draw is still determined by the motor, ESC, propeller, EDF unit and operating conditions.
Why Choose This Battery?
-
1800mAh capacity: A useful performance-oriented capacity for compact 4S aircraft.
-
Approx. 209g weight: Helps keep high-speed fixed-wing models relatively light.
-
86mm length: Compact format for tighter battery compartments.
-
120C continuous rating: Designed for demanding 4S brushless systems.
-
XT60 connector: Commonly used by performance RC airplanes and FPV platforms.
-
Standard 4S LiPo: Charges to 16.8V and does not require LiHV charging mode.
A Strong 4S Battery Choice for Durafly EFXtra and EFX Racer
The CNHL MiniStar 1800mAh 14.8V 4S 120C LiPo Battery with XT60 Plug is a particularly strong performance-oriented battery choice for the Durafly EFXtra and current EFX Racer.
Unlike a lower-capacity 3S alternative, 1800mAh 4S sits directly in the core performance direction of these compact speed racers. It provides the higher voltage associated with their 4S setups while keeping battery capacity and installed mass relatively conservative.
At approximately 209g, the MiniStar 1800mAh 4S helps preserve the quick acceleration and responsive feel expected from a compact high-speed aircraft rather than adding the additional mass of a much larger 2200–2600mAh 4S pack.
The 120C continuous rating is also well aligned with the short bursts of high current common during launch, vertical acceleration and full-throttle speed passes.
Battery installation should still be checked for physical clearance, secure retention, wire routing and final center of gravity before flight.
Compare this 1800mAh 4S performance setup with additional 3S and 4S choices in the Durafly EFXtra and EFX Racer Battery Collection.
4S Battery Option for the TBS Chupito 800mm FPV Airplane
The compact 1800mAh format also makes this battery relevant to compatible TBS Chupito 800mm FPV Airplane setups using 4S power.
For an FPV airplane, capacity should be considered together with battery mass. A larger battery may provide more potential cruising time, but additional weight can affect launch characteristics, stall speed, center of gravity and overall efficiency.
The 1800mAh MiniStar offers a middle ground between smaller 1300–1500mAh packs and heavier 2000mAh-plus batteries, making it useful when the aircraft can accommodate the additional energy without compromising balance.
Compare additional capacities in the TBS Chupito 800mm FPV Airplane Battery Collection.
4S Battery for FPV and Freestyle Builds
The combination of 1800mAh capacity, XT60 connection and 120C rating also makes this pack relevant to compatible FPV and freestyle builds designed around 4S power.
For multirotors, battery selection should take into account frame size, motor KV, propeller size, takeoff weight and intended flying style. An 1800mAh pack can provide more energy than the common 1300–1550mAh freestyle battery class, but the additional battery mass changes handling and momentum.
This makes the 1800mAh format particularly useful when longer cruising or mixed freestyle operation is more important than achieving the lowest possible takeoff weight.

Battery weight varies by model, so capacity alone should not be used to predict aircraft handling. Always compare the actual dimensions and weight of the specific packs being considered.
More 4S Battery Options
For additional capacity, compare the CNHL Black Series 2000mAh 4S 100C with XT60.
For a lighter high-discharge setup, compare the 2 Packs CNHL Black Series V2.0 1500mAh 4S 130C with XT60.
For even higher stated discharge capability in the 1550mAh class, compare the CNHL Ultra Black 1550mAh 4S 150C with XT60.
XT60 Connector
This battery uses an XT60 output connector, a common power connection for performance RC airplanes, FPV aircraft and multirotors.
The pack connects directly only when the model uses the corresponding XT60 device-side connector with correct polarity.
XT60 is not directly compatible with EC3, IC3, EC5 or IC5. Models using those connector systems require an appropriately rated adapter or professional connector conversion.
Standard 4S LiPo Charging
This is a standard 4S LiPo battery. Maximum balanced charge voltage is 4.20V per cell, or 16.80V total.
Do not use a 4.35V-per-cell LiHV charging mode with this battery.
The stated 5C value is the maximum charge rate. For routine charging, a balanced 1C rate is preferred. 5C is the stated maximum, not the everyday target.
FAQ
Is this battery 120C or 200C?
The product specification is 120C continuous and 240C burst. Older copy referring to a 200C maximum should not be used for this SKU.
Is this a standard LiPo or LiHV battery?
This is a standard 4S LiPo battery with a nominal voltage of 14.8V and a maximum fully charged voltage of 16.8V.
What are the dimensions?
The battery measures approximately 86 × 38.5 × 34mm in L × W × H order.
Is 1800mAh suitable for the Durafly EFXtra?
Yes, 1800mAh is a strong 4S performance-oriented capacity direction for the EFXtra. Confirm physical fit, battery position and final CG before flight.
Is this a good battery for the current Durafly EFX Racer?
Yes. The 1800mAh 4S format closely matches the performance direction of the current EFX Racer and is particularly attractive when pilots want to keep battery weight relatively low.
Why choose 1800mAh instead of 2000mAh?
The 1800mAh capacity generally favors lower battery mass and responsive handling, while a 2000mAh pack carries more energy. The better choice depends on the actual battery weights, dimensions and the aircraft's CG range.
Does 120C mean the aircraft always draws high current?
No. 120C is the battery's stated continuous discharge rating. Actual current draw depends on the motor, ESC, propeller, EDF unit and operating conditions.
Should this battery always be charged at 5C?
No. For routine charging, a balanced 1C rate is preferred. The 5C specification is the maximum charge rate, not the everyday target.
