Key Features

• 4-Cell NiMH Configuration — The four-cell arrangement delivers a nominal 4.8 volts, which is the standard voltage specification for many mini RC applications and provides stable power delivery throughout the discharge cycle, ensuring consistent performance across multiple charge cycles.
• 400mAh Capacity — This capacity sits comfortably within the 250-499mAh range and is specifically designed for lightweight mini RC models where excessive weight would compromise handling and speed, making it the optimal choice for small-scale RC vehicles that demand minimal power draw.
• JST Connector — The JST plug is one of the most commonly used connector types in mini RC applications across the UK market, ensuring straightforward plug-and-play installation with compatible receivers and power distribution systems without requiring adapters or modifications.
• Red Colouration — The bright red finish aids in quick visual identification in your battery collection, helping you distinguish this pack from other power sources at a glance, which is especially useful when you operate multiple RC vehicles simultaneously.
• Genuine HuiNa Component — Manufactured by HuiNa themselves, this battery is the authentic OEM (Original Equipment Manufacturer) component, guaranteeing that it meets the exact specifications and quality standards set by the vehicle designer, eliminating compatibility concerns and ensuring optimal performance.
• NiMH Chemistry — Nickel-Metal Hydride technology is robust, relatively forgiving of overcharge conditions compared to lithium alternatives, and requires no special balancing procedures, making it ideal for beginners and casual RC operators who prioritise safety and simplicity over absolute performance.

Technical Performance

The HuiNa CY1331 battery pack represents a straightforward, dependable power solution built with materials engineered to withstand repeated charge and discharge cycles. The four-cell NiMH configuration generates 4.8 volts, which is the industry-standard voltage for mini RC models and power packs in this weight category. At 400mAh capacity, this battery supplies adequate energy for extended play sessions on mini RC cars, crawlers, and compact racers without adding unnecessary weight that would diminish acceleration and top speed. The JST connector is soldered directly to the cells using industry-standard techniques, ensuring reliable electrical contact and safe operation. NiMH cells are particularly robust when it comes to handling partial discharges and irregular charging patterns, which makes this battery forgiving for hobbyists who may not employ precision battery management protocols. The pack can be recharged using standard NiMH chargers widely available throughout the UK RC hobby market, and the cells maintain relatively stable voltage output even as the battery approaches the end of its discharge cycle, providing predictable handling characteristics throughout your RC session. This battery has been specifically engineered as the factory component for HuiNa CY1331 mini models, meaning every aspect of its performance profile — from voltage regulation to connector compatibility — has been optimised for seamless integration with the intended host vehicle.

Frequently Asked Questions

• What is the HuiNa CY1331 battery compatible with? — This battery is the factory-specification power pack for HuiNa CY1331 mini RC models and other RC applications utilising 4.8V NiMH power sources with JST connectors. If your RC vehicle features a JST-type connector and is designed to operate on 4.8V nominal voltage, this battery should be compatible, though we always recommend checking your specific model's documentation before purchase.
• How long does this battery take to charge? — Charge time depends on your charger's output rating; however, NiMH batteries typically charge in 1-4 hours using a standard RC battery charger rated for NiMH packs in the 400mAh capacity range. Never use chargers designed exclusively for LiPo batteries, as these employ different charging protocols and could damage NiMH cells.
• Is this suitable for beginners? — Yes, absolutely. NiMH batteries are considered one of the most beginner-friendly power sources in the RC hobby because they are forgiving of charging mistakes, require no special balancing equipment, and pose minimal fire or safety risks if handled reasonably. There is no need for specialist LiPo charging bags or constant voltage monitoring — simply charge with an appropriate NiMH charger and your battery is ready to deploy.
• How many charge cycles will this battery last? — Quality NiMH cells typically deliver between 500 and 1,000 full charge cycles before capacity begins to noticeably diminish, depending on charging practices and storage conditions. This makes them cost-effective for casual hobby use, as you can operate your mini RC vehicle for many months or years before requiring replacement.
• Can I use this battery in other RC vehicles? — Provided your other RC models feature JST connectors and operate on 4.8V nominal voltage, this battery may be compatible. However, always verify your vehicle's battery specification before attempting to use this pack, as using an incorrect voltage battery can damage your RC model's receiver and electronic components.
• What is the difference between NiMH and LiPo batteries? — NiMH batteries like this one are more forgiving and safer for beginners, require less specialised charging equipment, and pose lower fire risk. LiPo batteries offer higher energy density and longer runtime for the same weight, but require careful handling, special balancing chargers, and appropriate storage precautions. For mini RC models designed for NiMH, this battery is the correct choice.
