Frequently Asked Questions

• Will this transmitter battery fit my FrSky Taranis X9D radio? — Yes, this GENSACE battery is specifically noted as compatible with the FrSky Taranis X9D, one of the most popular RC transmitters used throughout the UK. However, we always recommend verifying the physical dimensions (92 x 29 x 24mm) and connector type (BEC) match your specific radio model before purchase, as transmitter compartment sizes can vary between different manufacturer models and generations.
• How long will this battery last per charge? — The 2700mAh capacity provides several hours of runtime depending on your transmitter's power consumption, which varies based on whether you're using LCD screens, LED backlighting, telemetry modules or other power-hungry features. Typical runtime for most modern transmitters is between 8 and 12 hours of continuous use per full charge, making this an excellent choice for full-day RC sessions at UK flying sites or racing venues.
• Is this 3S battery safe for my transmitter? — Yes, the 11.1V output of this 3S LiPo is the standard voltage for modern RC transmitters and is perfectly safe when used with equipment designed for 3S packs. GENSACE batteries incorporate proper cell balancing and protection circuitry to ensure safe operation. Always charge using a quality LiPo charger with balancing capability and never leave charging batteries unattended.
• Can I use this battery in my older transmitter? — Older transmitter models may have been designed for different battery types (NiMH, NiCd or 2S LiPo). Before using this 3S battery, verify your transmitter's original battery specifications and voltage requirements. Using an incorrect voltage battery could damage your transmitter's electronics or provide insufficient power. Consult your transmitter manual or contact our support team if you're unsure of your system's requirements.
• What makes GENSACE batteries different from cheaper alternatives? — GENSACE is a recognised manufacturer of RC batteries with strict quality control processes, consistent cell performance and proper safety standards. Cheaper batteries may use lower-grade cells that suffer from voltage sag, reduced cycle life or potential safety issues. Investing in a quality GENSACE battery ensures reliable long-term performance and reduces the risk of battery failure during critical flights or races.
• How often should I charge this battery? — Lithium polymer batteries perform best when recharged after each use. Do not allow the battery to fully discharge between sessions, as this can reduce overall lifespan. Store the battery at approximately 50% charge in a cool, dry location when not in use for extended periods. A quality LiPo charger with balancing capability is essential for maintaining optimal cell health and longevity.
