Overview
The Spektrum 7.4V 1300mAh 2S 5C LiPo Receiver Battery is a reliable power solution designed specifically for RC receivers across a wide range of remote control vehicles. Whether you're operating an RC car, truck, buggy or other RC model in the UK, having a dedicated receiver battery ensures consistent performance and eliminates the need to draw power from your main drive battery. This lightweight LiPo pack delivers the stable voltage output that modern Spektrum receivers demand, maintaining signal integrity and response quality throughout your flying or driving sessions. Built to Spektrum's quality standards, this receiver battery is an essential component for any serious RC enthusiast looking to optimise their setup.
Receiver batteries are often overlooked but are absolutely critical to RC performance. Unlike drive batteries that power your motor, a dedicated receiver battery ensures your radio receiver, servo controller and all control electronics operate independently at peak efficiency. The 7.4V output is perfect for applications requiring two-cell lithium polymer power, and the 1300mAh capacity provides ample runtime for extended sessions. With its JST-RCY connector, this battery integrates seamlessly with Spektrum receiver systems and compatible RC equipment throughout the UK hobby market.
Key Features
- 7.4V Lithium Polymer Chemistry — This battery delivers 7.4 volts across two cells, each cell providing 3.7V of nominal voltage, which is the standard requirement for powering modern RC receivers and control electronics with reliable performance.
- 1300mAh Capacity — The 1300 milliamp-hour capacity ensures extended runtime for your receiver and servo systems, allowing you to run longer sessions without power degradation or loss of signal quality.
- 2S1P Cell Configuration — Two cells in series deliver the required voltage step-up from a single 3.7V cell, providing the dual-cell power architecture that Spektrum receivers are engineered to utilise.
- 5C Continuous Discharge Rate — With a maximum continuous discharge rate of 5C, this battery can supply up to 6.5 amps continuously, providing more than enough current for receiver, servo and control electronics throughout extended RC sessions.
- JST-RCY Connector — The JST-RCY connector type ensures proper compatibility with Spektrum receiver systems and offers a secure, polarised connection that prevents reverse polarity mistakes.
- 1C Charge Rate — The standard 1C charge rate of 1.3 amps allows safe, balanced charging at a measured pace, extending battery lifespan and maintaining cell health for many seasons of RC use.
- Compact Dimensions — Measuring just 2.52 inches in length, 1.1 inches in width and 0.63 inches in height, this receiver battery fits easily into tight receiver compartments without consuming valuable space in your RC chassis.
- Lightweight Construction — At just 1.94 ounces (55 grams), this battery adds minimal weight to your RC model, helping maintain the balance and performance characteristics of your vehicle.
- JST-XH Balance Connector — The integrated JST-XH balance connector allows you to monitor individual cell voltage and maintain optimal cell balance, critical for extending battery lifespan and ensuring safe operation.
Technical Performance
The Spektrum 7.4V 1300mAh 2S LiPo Receiver Battery represents a purpose-built solution for powering modern RC receiver systems across the entire spectrum of remote control hobbies in the UK. Constructed using lithium polymer cell technology, this two-cell battery pack is engineered to deliver stable, regulated power to receivers, servos and control electronics that require more current than traditional NiMH receiver batteries can provide. The 5C maximum continuous discharge rate translates to a sustainable output of 6.5 amps, providing abundant headroom for servo actuation, signal processing and electronic speed control feedback systems. The two-cell series configuration ensures the 7.4V output that modern Spektrum receivers require for optimal operation, whilst the 1300mAh capacity delivers extended session runtimes without voltage sag. The 1C charge rate of 1.3 amps ensures battery longevity through measured, safe charging protocols. Finished with both a JST-RCY power connector and JST-XH balance connector, this battery integrates seamlessly into Spektrum receiver ecosystems whilst enabling proper cell balance monitoring through compatible charging equipment. The compact footprint of just 64mm length and 55-gram weight makes this battery suitable for installation in tight receiver compartments common to modern RC buggies, RC monster trucks, RC crawlers and competition-level RC vehicles throughout the UK.

Frequently Asked Questions
- What type of receiver systems does this battery power? — This 7.4V 2S LiPo receiver battery is designed specifically for Spektrum receivers and other modern RC receiver systems that require 7.4-volt power inputs. The JST-RCY connector ensures compatibility with Spektrum receiver harnesses and related equipment across RC cars, trucks, buggies and other RC vehicles.
- How long will the 1300mAh capacity run my receiver during a typical RC session? — Runtime depends on your receiver's current draw and servo actuation frequency, but the 1300mAh capacity is sufficient for extended sessions. Most RC receivers draw 100-300 milliamps during operation, meaning this battery can theoretically run your receiver system for 4-13 hours before requiring recharge, though actual runtime will be shorter due to servo activity.
- Can I charge this battery with standard RC chargers? — Yes, the 7.4V 1300mAh 2S LiPo receiver battery can be charged with any modern RC LiPo charger that supports 2S lithium polymer packs. The 1C charge rate means you should charge at 1.3 amps for safe, balanced charging. The integrated JST-XH balance connector allows proper cell balancing during the charge cycle.
- What is the difference between a receiver battery and a drive battery? — A receiver battery powers only your receiver, servos and control electronics, whilst a drive battery powers the main motor and ESC. Using a separate receiver battery ensures stable voltage for signal quality and servo response, preventing voltage sag from high motor current from affecting receiver performance. This separation is essential for competitive RC in the UK where signal integrity directly impacts control responsiveness.
- Is this battery suitable for first-time RC users? — Yes, this Spektrum receiver battery is suitable for users of all experience levels. Receiver batteries are fundamental components of any RC setup, and this pack delivers reliable performance for beginners and experienced hobbyists alike. It requires only standard RC charging equipment and basic LiPo battery safety precautions.
- What safety precautions should I take with this LiPo battery? — Lithium polymer batteries require standard safety protocols: never overcharge, never fully deplete, store in a fireproof LiPo bag when not in use, and keep away from moisture. Always use a compatible LiPo charger with cell balance capability, and inspect the battery regularly for any signs of swelling or damage before use.
