Note: The listed products cover a range of voltages (6V and 4.8V) with Hitec-compatible connectors, plus one alternative Li-Fe option. Each choice focuses on reliability, compatibility with common receivers, and ease of charging to maximize flying time and performance.
Tenergy 6V 2000mAh NiMH Receiver Battery Pack (2-Pack)
The first listed option comprises a 2-pack of 6V, 2000mAh NiMH receiver batteries with Hitec connectors. This configuration supports rapid charging to minimize downtime between flights. The packs are designed for compatibility with popular RC airplane and helicopter receivers, including brands such as Hitec, Futaba, and JR. Each battery weighs about 0.31 lb (5 oz) and measures roughly 2.83 x 1.97 x 0.59 inches, making them suitable for a variety of airframe layouts without significant weight changes.
Tenergy 4.8V 2000mAh NiMH RX Battery Pack
This 4.8V NiMH battery pack offers 2000mAh capacity with a Hitec connector. It’s designed for a broad range of RC receivers across popular brands such as Hitec, Futaba, and JR. The compact pack weighs approximately 0.24 lb (3.84 oz) and measures around 2.28 x 2.05 x 0.59 inches, which helps maintain an efficient balance for smaller airframes while delivering reliable power to the receiver during flights.
Tenergy NiMH Receiver RX Battery With Hitec Connectors 6V 2000mAh
This 6V, 2000mAh NiMH unit is compatible with various receivers and emphasizes a balance between high capacity and a compact footprint. It’s designed to power radio receiver planes and can be rapidly charged to shorten downtime between flights. Weighing about 0.31 lb (5 oz) with dimensions near 2.83 x 1.97 x 0.59 inches, it remains a versatile choice for mid-sized RC planes and other hobby electronics using a Hitec connector.
Tenergy 4.8V 2000mAh NiMH Battery Pack With Hitec Connectors
This 4.8V, 2000mAh pack is tailored for Futaba and similar radio systems, featuring a Hitec-compatible connector. It is designed for aircraft receivers and accessories, ensuring sturdy power delivery for extended flights. The compact dimensions (approximately 1.97 x 1.14 x 1.14 inches) contribute to a light overall load for smaller RC planes, while the 2000mAh rating supports longer standby and in-flight performance.
Spektrum 2200mAh Li-Fe Receiver Battery
This alternative battery chemistry uses Li-Fe (lithium iron) cells with a 2S configuration rated at 2200mAh. Li-Fe options offer higher energy density and stable voltage under load, which can translate to longer flight durations and consistent performance. Note that this is a different chemistry than NiMH and requires compatible receivers and charging equipment. Usage is common in Spektrum-compatible systems, and it supports a slightly higher voltage profile suitable for certain radio setups. Always confirm connector compatibility and airframe weight when selecting Li-Fe cells.
Buying Guide: Key Purchase Considerations
- Battery chemistry and voltage: NiMH packs are robust, forgiving, and widely compatible with many hobby receivers, typically at 4.8V to 6V. Li-Fe packs offer higher energy density and stable voltage but require compatible charging and electronics. Match voltage to your receiver’s requirements and airframe design.
- Capacity and weight: Higher mAh means longer run time but more weight. Balance flight duration with aircraft weight and center of gravity. For mid-sized planes, 2000 mAh is common; for smaller airframes, lighter packs (e.g., ~300–800 mAh) may be preferred.
- Connector compatibility: Hitec-compatible connectors are common in RC gear. Verify that the connector type matches your receiver without modifications to avoid power losses or fit issues.
- Physical dimensions: Packs should fit the available space in the airframe and not disrupt the balance. Check length, width, height, and weight against your model’s battery bay.
- Charging options: Look for batteries that support rapid charging or have readily available charge accessories. Proper charging helps maximize cycle life and minimize downtime between flights.
- Brand and warranty: Reputable brands with good customer support help ensure compatibility across receivers and future replacements. Consider warranty terms and availability of spare parts or replacements.
- Maintenance and lifecycle: NiMH cells provide reliable lifecycle performance with many charge-discharge cycles. Proper storage and charging practices extend battery life and performance in the field.
- Flight profile considerations: For aerobatic or high-demand flights, a higher-capacity pack can sustain longer durations, but ensure the airframe can handle the extra weight without compromising handling.
