• Pre-Fitted Futaba + JST-EHR Discharge Leads — The battery arrives with discharge connectors already installed and ready to connect to your transmitter or receiver, eliminating the need for additional soldering or connector modifications and reducing setup time to mere seconds.
• JST-XHR Balance Connector — This industry-standard balance connector allows for safe and balanced charging of both cells simultaneously, ensuring optimal cell voltage equalisation and maximum battery health during the charging process.
• Compact and Lightweight Design — Measuring just 92 × 31 × 16mm and weighing approximately 93 grams, this pack has a slim profile that fits easily into the radio compartments of popular transmitter models without adding unnecessary weight to your system.
• Wide Radio Compatibility — This battery is specifically designed to work with leading RC radio systems including Sanwa MT4, M11X, and M12 transmitters, as well as Futaba T6J, T8FG, and 12FG models, plus the Taranis X9D 2019 Plus—making it a versatile choice for many UK RC pilots.

Technical Performance

This Gens Ace receiver pack represents quality engineering focused on the specific power requirements of radio transmitter systems. The 2S1P configuration (two cells in series, one in parallel) delivers stable 7.4V output throughout the discharge cycle, maintaining consistent performance and reliable transmitter operation during your RC sessions. The conservative 1C discharge rate—delivering 2.7 amps maximum discharge—is deliberately low compared to high-performance RC car batteries, reflecting the fact that transmitters and receivers draw relatively modest current compared to brushless motors. This design philosophy extends battery lifespan significantly and reduces heat generation, keeping your radio equipment cool and reliable even during extended use. The approximately 93-gram weight ensures minimal impact on your transmitter's handling whilst the compact 92 × 31 × 16mm footprint provides the space-saving profile needed for modern radio compartment design. The combination of JST-XHR balance connector and Futaba plus JST-EHR discharge leads means this battery integrates seamlessly with compatible systems, whether you're flying FPV, bashing an RC buggy, or competing in a 1/10th or 1/8th scale racing event. Gens Ace's manufacturing standards ensure consistent cell quality and reliable performance across every charge cycle, making this pack a dependable workhorse for serious RC enthusiasts throughout the UK.

Frequently Asked Questions

• Is the Gens Ace 2700mAh receiver battery compatible with my Futaba or Sanwa transmitter? — Yes, this battery is specifically designed for compatibility with Sanwa MT4, M11X, and M12 transmitters, as well as Futaba T6J, T8FG, and 12FG models, plus the Taranis X9D 2019 Plus. The pre-fitted Futaba connector makes installation straightforward for these systems. However, if you own a different transmitter model, we recommend checking the radio's battery compartment specifications and connector type before purchase.
• What does the 1C discharge rate mean, and why is it different from my RC car batteries? — The 1C discharge rate means this battery can safely discharge at a maximum of 2.7 amps (one times its capacity in milliamp hours). This conservative rating is deliberately lower than the 25C, 50C, or even 100C discharge rates found on typical RC car batteries, because transmitters and receivers draw far less current than brushless motors. The lower discharge rate in this specialised design optimises battery longevity, reduces heat, and ensures safe, reliable operation of your radio equipment during extended sessions.
• How long will this battery power my transmitter? — The 2700mAh capacity provides extended runtime for most radio systems, typically lasting through multiple full days of RC bashing or racing without needing recharge. Exact runtime depends on your specific transmitter model, usage intensity, and environmental factors, but the generous 2700mAh capacity ensures you'll have plenty of power for extended outdoor RC sessions without mid-day battery swaps.
• Do I need a special charger for this LiPo battery? — Yes, lithium polymer batteries require a dedicated LiPo charger with balance charging capability. You cannot use a standard NiMH or lead-acid charger. The JST-XHR balance connector on this pack allows you to use any quality LiPo charger with an XHR balance port, ensuring both cells charge equally and remain in perfect health. We recommend using a charger with an integrated balancer and low-current setting suitable for receiver packs.
• What is the difference between this receiver battery and a standard RC car LiPo battery? — The key difference is the discharge rate. This Gens Ace receiver pack has a conservative 1C discharge rate, whilst standard RC car batteries are typically rated at 25C, 50C, or higher. This means receiver batteries are optimised for the modest, consistent current draw of transmitter electronics, not the high-current demands of brushless motors. Additionally, receiver batteries often have different connector types (like the Futaba connector on this model) to match popular radio systems, whereas car batteries use XT90, EC3, or similar connectors designed for vehicle power systems.
• Is this battery suitable for beginners? — Absolutely. If you're new to RC and using one of the compatible Futaba, Sanwa, or Taranis radio systems, this Gens Ace battery is an excellent choice. The pre-fitted connectors mean no soldering is required, and the straightforward installation process makes it beginner-friendly. However, you will need a LiPo charger with balance charging capability, so factor that into your initial setup costs.
• What safety precautions should I take with this LiPo battery? — Like all lithium polymer batteries, this Gens Ace pack requires responsible handling. Always use a charger specifically designed for LiPo batteries with balance charging functionality. Never discharge the battery completely or allow individual cells to fall below 3.0V per cell. Store the battery in a cool, dry place away from metal objects that could cause short circuits. If the battery shows signs of swelling, damage, or poor performance, discontinue use immediately and dispose of it safely at a qualified recycling centre.
