Blomiky 2-Pack 3.7V 150mAh Li-Poly Pack
This pair of 3.7-volt LiPo batteries is designed as a direct replacement for S107G and similar mini helicopters. With a capacity of 150mAh and a 20C discharge rate, these batteries provide a compact, lightweight option that fits tight airframes. The form factor (approximately L26×W16×H6.6 mm) keeps the balance consistent for nimble flight, and the low weight helps preserve pitch and control responsiveness. Suitable as spares or replacements, they are commonly used with Cheerwing S107G and compatible Syma models.
Cecicebb 3.7V 150mAh Lipo Battery Pack
The Cecicebb 150mAh battery pack comes in a 5-pack, offering cost-effective spares for Syma S107/S107G helicopters. Each cell remains at 3.7V with a 20C discharge, matching the performance envelope of small hobby aircraft. The compact dimensions (about 26×16×6.6 mm) and a weight near 5 grams help maintain the aircraft’s center of gravity and flight characteristics. A convenient option for users who want to stock up on dependable replacements.
RCERA C032 350mAh 7.4V LiPo Battery
The RCERA C032 battery provides a higher capacity of 350mAh at 7.4V, aimed at longer flight times for compatible RC helicopters and micro aircraft. While the product listing highlights general durability and easy replacement, it is especially suitable for pilots seeking extended durations between charges in models that accept 2S LiPo packs. Always verify the exact cell model and dimensions to ensure a proper fit in your airframe.
2000mAh 7.4V Li-ion Battery with JST Plug
This high-capacity 2000mAh Li-ion pack is designed for longer-run RC sessions across a range of vehicles, including helicopters, cars, boats, and drones. With a 7.4V specification and a 15C discharge rate, it aims to balance power output with extended flight or run time. The JST plug and compact dimensions (about 2.75×1.45×0.74 inches) help it fit into a variety of airframes, though users should confirm space in the chassis and the compatible connector before purchasing.
URGENEX 2000mAh 7.4V Li-ion Battery
URGENEX offers a 2000mAh 7.4V Li-ion battery with a JST plug, aimed at expanding flight time for a broad range of RC helicopters, cars, boats, and trucks. The pack emphasizes a balance of high capacity and practical discharge (15C), enabling sustained power delivery during more demanding flight maneuvers or extended play. Its dimensions and weight are suitable for mid-to-large airframes that accept 2S packs, and the product notes recommend confirming compatibility with your specific model before use.
Buying Guide: Key Purchase Considerations
- Voltage and chemistry: Most small RC helicopters operate on 3.7V LiPo packs, while larger airframes use 7.4V LiPo or Li-ion packs. Match the battery voltage to your model’s original specification to avoid performance issues or damage.
- Capacity and runtime: Higher mAh ratings extend flight time but add weight. Balance your need for longer runtime with the airframe’s weight tolerance and CG (center of gravity).
- Discharge rate: For nimble aerobatics, a higher C-rate improves immediate power delivery. Check the motor and ESC limits to prevent over-discharge or heat buildup.
- Size and fit: Battery dimensions must fit the battery compartment and not obstruct moving parts. Confirm length, width, and height (and any required battery plugs) for a proper install.
- Connector compatibility: JST plugs are common on many hobby packs. Ensure the connector type matches your charger and ESC harness to avoid rewiring.
- Weight considerations: Heavier packs can alter CG and flight handling. Consider the total airframe weight and the impact on stability and lift.
- Spare availability and durability: Reputable brands offering multi-pack options can reduce downtime. Look for packs with good cycle life and consistent conductance.
- Safety and storage: Use proper LiPo storage bags and follow charging guidelines to prevent heat buildup or swelling. Never puncture or short-circuit cells.
These options cover a range of use cases—from quick replacement spares for micro helicopters to higher-capacity packs for longer sessions. When selecting, prioritize compatibility with your specific model, desired flight duration, and overall aircraft weight. Always pilot-test with care after installing a new pack to confirm balance and power characteristics align with your expectations.
