Technical Performance

This Volantex LiPo battery represents solid engineering and manufacturing excellence in the world of RC power systems. The 11.1V nominal voltage across three cells in series provides the ideal power level for small RC aircraft, FPV quadcopters, racing drones, and compact RC vehicles available in the UK hobby market. The 400mAh capacity delivers approximately 4.44 watt-hours of total energy, which translates to practical flight times of 5-15 minutes depending on your specific model's power demands and flight characteristics. The 25C discharge rating of this battery allows for peak discharge currents up to 10 amps during maximum throttle application, making it suitable for both leisurely cruising and spirited aerobatic manoeuvres. The lithium polymer chemistry employed in this battery provides superior energy density compared to older nickel-based battery technologies, meaning you get more flight time in a lighter, more compact package. The JST connector is soldered with precision to ensure reliable electrical connections that won't degrade over hundreds of charge and discharge cycles. Like all quality LiPo batteries, proper care and maintenance — including storage at partial charge, regular balancing, and safe charging practices — will extend the service life considerably, making this an economical choice for serious RC enthusiasts who plan to use their equipment regularly throughout the year.

Frequently Asked Questions

• What is a 3S LiPo battery and why should I choose the Volantex 400mAh model? — A 3S LiPo battery contains three lithium polymer cells connected in series, delivering 11.1 volts nominal output (typically ranging from 12.6V fully charged to 9V when depleted). The Volantex 400mAh 3S is an excellent choice because it combines reasonable capacity for extended flights with a lightweight design perfect for small RC aircraft, FPV quads and compact drones available across the UK RC market.
• Is this battery suitable for beginners in RC hobbies? — Yes, this battery is beginner-friendly, though you will need a dedicated LiPo charger and a basic understanding of LiPo safety practices. The 400mAh capacity makes this ideal for getting started in small-scale RC flying without the cost and complexity of larger batteries. We recommend all LiPo battery users read the safety guidelines carefully and follow best practices for charging, storage, and handling.
• What charger do I need to use with this Volantex LiPo battery? — You will need a dedicated LiPo battery charger with balancing capabilities. The charger must support 3S LiPo charging profiles and ideally include a balance connector to ensure each cell charges evenly. Many modern RC chargers sold in the UK, including those from brands like Hobbywing, support 3S LiPo charging and will work perfectly with this battery.
• How long will this battery last in terms of charge cycles? — With proper care, a quality LiPo battery like this Volantex model can deliver 200-300 full charge cycles or more. To maximise lifespan, store the battery at approximately 50% charge when not in use, avoid over-discharging below 3.0V per cell, and allow the battery to cool between flights before recharging.
• What models and equipment can I use this battery with? — The Volantex 11.1V 400mAh LiPo battery with JST connector is compatible with any RC model, drone, quadcopter or aircraft that accepts 3S LiPo batteries with JST connectors. This includes small FPV racing quads, fixed-wing trainer aircraft, micro drones, and compact RC vehicles. Always verify your model's battery requirements before connecting.
• Is the JST connector standard and will it fit my equipment? — Yes, the JST connector is one of the most common standard connectors in RC hobbies across the UK. However, some models use alternative connectors like XT30 or XT60. Before purchasing, confirm your model uses JST connectors, or you may need a compatible connector adapter.
• How should I store this LiPo battery when not in use? — LiPo batteries should be stored in a cool, dry place at approximately 50% state of charge. Never leave them fully charged for extended periods, as this stresses the cells and reduces overall lifespan. Many RC enthusiasts store batteries in purpose-designed LiPo bags to protect against potential damage or thermal runaway in the unlikely event of a fault.
