Frequently Asked Questions
- What RC models can I use this 1S LiPo battery with? — This battery is compatible with any RC device, receiver or control board designed for single-cell (1S/3.7V) lithium polymer power. Common applications include micro RC helicopters, small quadcopters, lightweight RC airplanes, and small RC car receivers. Check your device's power requirements before use to ensure compatibility.
- Is the Radient 850mAh 1S LiPo suitable for beginners? — Yes, this battery is suitable for hobbyists aged 14 and above who have received proper instruction on lithium polymer battery safety and charging procedures. Beginners should always learn correct battery handling, storage and charging practices before operating LiPo batteries, and should never leave batteries unattended during charging.
- How long does this battery take to charge? — Charging time depends entirely on the charger you use and the charge rate selected. A typical 1-amp charger might fully charge this battery in approximately one hour, though faster chargers with higher output may reduce this time. Always use a dedicated lithium polymer battery charger with appropriate cell detection capabilities.
- What is the JST connector and why does it matter? — The JST connector is the most common connector type used in small RC battery applications throughout the UK and worldwide. Its standardisation means this battery will work with the majority of RC receivers, chargers and control boards without requiring adapters or modifications, making it highly compatible with existing RC equipment.
- How should I store this battery when not in use? — Lithium polymer batteries should be stored in a cool, dry place at room temperature (around 15-25°C). Store the battery at approximately 50% charge state if you won't be using it for extended periods. Never store LiPo batteries in extreme heat, freezing conditions, or damp environments, and always keep them away from flammable materials.
- What does the 35C discharge rating mean for my RC model? — The 35C rating indicates how much continuous current the battery can safely supply. For this 850mAh battery, this translates to approximately 29.75 amps maximum continuous discharge. This rating ensures the battery can power typical small RC applications without excessive heat generation or cell damage, making it suitable for moderate to demanding use.
