Key Features

• 7.4V Two-Cell LiPo Configuration — This battery delivers 7.4 volts of power through two lithium polymer cells in series, providing the optimal voltage range for HuiNa RC construction vehicles and ensuring maximum performance from your model's motor and electronic components without risk of over-voltage damage.
• 500mAh Capacity — The 500mAh energy storage capacity is perfectly matched to smaller and mid-sized HuiNa RC models, offering extended runtime compared to smaller batteries whilst maintaining manageable weight that doesn't compromise your vehicle's handling and responsiveness.
• SM4P Connector Type — The standardised SM4P connector (also known as JST SM4P) provides a secure, reliable connection to your HuiNa model's receiver and power distribution system, ensuring consistent electrical contact and safe disconnection every time you use the battery.
• Multi-Model Compatibility — This single battery pack works with eight different HuiNa models (1535, 1552, 1553, 1554, 1571, 1572, 1577, 1579, 1585), making it an economical choice if you own multiple HuiNa construction vehicles and want standardised power sources across your collection.
• Lightweight Lithium Polymer Construction — LiPo battery technology delivers high energy density in a compact, lightweight package, meaning you can achieve longer runtimes than equivalent NiMH batteries whilst keeping your RC model's weight distribution optimal for realistic operation.
• Ready to Use Out of the Box — The CYP1021 battery arrives fully assembled with its connector already attached, ready to install into your HuiNa model without any additional preparation or modification required.
• Genuine HuiNa Specification — This is an official HuiNa part (not a third-party clone), manufactured to the original specification by the brand's engineering team, ensuring perfect fit, compatibility and safety performance with your RC model.

Technical Performance

This HuiNa replacement battery pack represents the ideal power solution for owners of HuiNa's range of construction-themed RC vehicles available in the UK hobby market. The 7.4V output voltage (nominal 2S LiPo) is specifically calibrated for HuiNa's proprietary electronic speed controllers and motor configurations found in models like the 1535 (14-channel RC excavator), 1552, 1553, 1554, 1571, 1572, 1577, 1579, and 1585. The 500mAh capacity provides adequate energy storage for realistic operational periods typical of RC construction vehicles — usually between 20-40 minutes of continuous operation depending on driving style and vehicle loading. The lithium polymer chemistry ensures stable voltage delivery throughout the discharge cycle, meaning your HuiNa model maintains consistent speed and torque from the moment you connect the battery until the charge is depleted. The SM4P connector specification guarantees compatibility with HuiNa's dedicated receiver circuits and protective mechanisms including low-voltage cutoff protection (if fitted to your model's receiver). LiPo technology is recognised as the performance standard for modern RC vehicles in the UK, offering superior energy density compared to outdated NiMH alternatives, lighter weight than equivalent capacity lead-acid systems, and a flatter discharge curve that maintains power delivery under load. The 14500 cell designation refers to the specific cylindrical LiPo cell dimensions (14mm diameter, 50mm length) used in this pack's two-cell configuration.

What's in the Box

Frequently Asked Questions

• Is this battery compatible with my HuiNa RC model? — Yes, the CYP1021 is specifically engineered for HuiNa models 1535, 1552, 1553, 1554, 1571, 1572, 1577, 1579, and 1585. Check your model number on the vehicle documentation or box to confirm compatibility before purchasing. If you're uncertain which model you own, the SM4P connector type is distinctive and easy to visually match with your existing battery socket.
• What is the runtime I can expect from this battery? — The 500mAh capacity typically delivers 20-40 minutes of continuous operation on HuiNa RC construction vehicles, though actual runtime varies depending on driving conditions, motor load, and terrain. More aggressive driving style will consume the charge faster than gentle operational use, and running the vehicle on steeper inclines will reduce total operational time compared to level ground operation.
• Can I charge this battery in my standard RC battery charger? — Yes, provided your charger has an SM4P connector compatibility (or accepts an SM4P adapter) and supports 2S LiPo charging profiles. Modern balance chargers and multi-chemistry chargers sold in the UK almost universally support SM4P connectors. Always consult your charger's manual to confirm it supports 7.4V LiPo charging, and ensure you use the correct charging profile to avoid damaging the battery or creating safety hazards.
• Is this a genuine HuiNa part or a third-party replacement? — This is a genuine HuiNa original part, manufactured to HuiNa's specifications. The part number CYP1021 is the official HuiNa designation, ensuring perfect compatibility and quality assurance. Always purchase from authorised retailers like RC Model Shop to guarantee authenticity and avoid counterfeit batteries that may perform unreliably or present safety risks.
• What safety precautions should I follow when using this LiPo battery? — LiPo batteries require sensible safety practices: store the battery at room temperature in a fireproof container when not in use; never leave a charging battery unattended; disconnect the battery immediately if you notice any swelling, unusual heat, or smell during operation; and always use a reputable charger designed for LiPo batteries. LiPo batteries are safe when treated with proper respect, but they demand more care than older NiMH technology.
• Can I use this battery with my other RC vehicles? — This battery is specifically engineered for HuiNa models and uses the SM4P connector. If your other RC vehicles use different voltage systems (like 6V NiMH or different LiPo configurations) or different connector types (like JST, Deans, or XT60), you would need a different battery pack. Attempting to force-fit incompatible batteries can damage your RC model's electronics.
• How long will this battery last before it needs replacing? — With proper care and regular use, a quality LiPo battery typically remains reliable for 300-500 complete charge-discharge cycles. Over time, battery capacity gradually reduces, and you may notice shorter runtimes after a year or two of active use. When the battery's runtime drops below 50% of its original capacity, it's usually time to replace it with a fresh pack.
