Frequently Asked Questions

• What RC models is the Radient 650mAh 1S LiPo suitable for? — This battery is specifically designed for micro RC models and small applications that require a 1S (3.7V) power source with a JST connector. It is ideal for small drones, lightweight aircraft, micro RC cars, and any compact RC equipment where a single-cell LiPo battery is the specified power source. Check your model's specifications to confirm it uses 1S voltage and a JST connector.
• Is the Radient 1S 650mAh LiPo battery good for beginners? — Yes, absolutely. Single-cell LiPo batteries are considerably simpler to manage than multi-cell packs. There is only one cell to balance, charging is straightforward with any basic 1S charger, and the compact size makes handling and storage easy. The 35C discharge rating provides excellent performance without requiring complex understanding of discharge rates. This battery is recommended for users aged 14 and above.
• What charger do I need for the Radient 1S 650mAh battery? — You will need a LiPo-compatible charger that supports 1S (single-cell) charging. Many entry-level RC chargers and multi-cell chargers have a 1S mode available. Ensure your charger is set to 1S mode and charges at an appropriate current (typically 0.5-1C for safe charging, which would be 325-650mA for this 650mAh battery). Never use standard alkaline battery chargers or NiMH-only chargers.
• How long will the battery last per charge? — Runtime depends on the current draw of your specific RC model. As a general guide, a 650mAh battery powering a motor drawing 10A would provide approximately 3-4 minutes of runtime. Lighter models with lower current draw will achieve longer runtimes. Check your equipment's power specifications for more accurate estimates.
• What does the 35C rating mean? — The 35C rating refers to the discharge rate capability of the battery. It means the battery can safely discharge at 35 times its capacity (650mAh × 35 = 22.75A maximum continuous discharge). This high discharge rating makes the battery suitable for high-performance applications whilst maintaining safety and cell integrity.
• Can I use this battery with different RC brands? — Yes, as long as your RC equipment is designed for 1S (3.7V) power and features a JST connector. The battery is brand-agnostic and will work with any compatible model, whether it's a micro drone, small aircraft, or compact RC car from any manufacturer.
• What are the physical dimensions and weight? — The battery measures 56mm in length, 30mm in width, and just 7mm in height, with a total weight of 22.5g. These compact dimensions make it ideal for space-constrained RC models where every millimetre counts.
• Is this battery waterproof? — Whilst the battery itself can withstand brief water exposure due to its sealed case construction, lithium polymer batteries should not be deliberately submerged or exposed to prolonged moisture. Always store and charge in a dry environment and allow the battery to fully dry before charging if it becomes damp.
• How should I store the Radient 1S 650mAh battery? — Store the battery in a cool, dry place at room temperature (ideally between 15-25°C). If storing for extended periods, keep the battery at approximately 50% charge state (around 3.85V). Always use the soft case provided and store in a fireproof container or LiPo-safe storage bag for maximum safety.
