Technical Performance
This Spektrum Smart LiPo battery is engineered for serious RC aircraft performance with a 14.8V nominal voltage across 4 cells (3.7V per cell), delivering 3200mAh of capacity for sustained flight sessions. The 30C maximum burst discharge rate ensures responsive throttle control and powerful acceleration when you need it most, whilst the 5C maximum charge rate allows for reasonably quick turnaround between flights. With 47.36 watt-hours of total energy capacity and a maximum sustained discharge current of 96 amps (3200mAh × 30C), this battery is suitable for aerobatic aircraft, fast-flying models, and high-powered racing applications. The battery features charge protection circuitry and short circuit protection built-in, safeguarding your valuable RC equipment from electrical faults. Weighing 325 grams (11.4 ounces) and measuring 141mm in length, 42mm in width, and 26mm in height, this battery offers a compact footprint that fits into many standard RC aircraft battery compartments. The 12 AWG wire gauge provides adequate current-carrying capacity whilst maintaining flexibility for installation, with a 60mm balance lead for cell monitoring and an 89mm discharge lead for main power connection. The protective metal alloy exterior helps dissipate heat during high-discharge operations, keeping internal cell temperatures within safe operating ranges and maintaining consistent performance throughout your flying session.

Frequently Asked Questions
- What is Spektrum Smart battery technology and how does it improve my RC flying experience? — Spektrum Smart technology uses an integrated microchip to store unique battery parameters and health data. When you connect this battery to a compatible Spektrum Smart charger, the battery automatically uploads all its information including charge rates, previous charge cycles, temperature history, and any error events. This means you never have to manually input battery specifications—simply connect the battery, press the start button, and the charger handles everything else. The charger remembers your preferred settings, so subsequent charges are even faster. This technology takes the guesswork out of battery management, ensures optimal charging conditions every time, and helps you monitor battery health to make informed decisions about when to retire older packs.
- Will this Smart LiPo battery work with my existing RC charger and aircraft? — Yes, the IC3 connector is fully backwards compatible with popular EC3 connectors used on many RC aircraft and chargers. However, to take advantage of all Smart features including automatic smart discharge and data logging, you'll need a compatible Spektrum Smart charger. Without a Smart charger, the battery functions as a standard high-quality LiPo battery. If you're considering upgrading your charger, a Spektrum Smart charger will unlock the full potential of this battery and make battery management significantly easier.
- What does the smart discharge feature do and why is it important? — Smart discharge is an automatic feature that protects your battery when programmed into a Spektrum Smart charger. After you've finished flying, if you leave the battery for a set period (between 12 and 240 hours), the battery automatically discharges itself to a safe storage voltage. This is crucial because lithium polymer cells degrade when left fully charged for extended periods. By automatically maintaining a safe storage voltage, smart discharge significantly extends your battery's lifespan, maintains better performance over time, and reduces the risk of battery damage or failure. This feature is particularly valuable for RC enthusiasts who fly intermittently or store batteries between flying seasons.
- Is this battery suitable for my high-performance RC aircraft or racing model? — Absolutely. The 30C discharge rate makes this battery ideal for high-performance applications including competitive RC aircraft flying, aerobatic manoeuvres, and power-hungry racing models. The 3200mAh capacity provides excellent energy density while maintaining a compact size suitable for most aircraft. However, you should verify that your aircraft's battery compartment can accommodate the 141mm length and 325-gram weight, and that your motor and ESC are rated for the 14.8V nominal voltage and 96-amp maximum current output. Check your aircraft's manual or consult with RC specialists to ensure proper compatibility.
- How long does this battery take to charge and what's the charge current? — The battery has a maximum charge rate of 5C, which equals 16 amps for this 3200mAh capacity. The standard charge current is 3.2A (1C rate), which would fully charge the battery in approximately one hour under normal conditions. Using the full 5C rate with a compatible Spektrum Smart charger could achieve faster charging in around 12 minutes, though charging at lower rates is generally gentler on battery longevity. When connected to a Spektrum Smart charger, you can customise the charge rate to suit your needs, and the charger will remember your preference for future charges.
- What protection features does this battery include? — This battery includes integrated charge protection circuitry and short circuit protection to safeguard both the battery and your RC equipment from electrical faults. Additionally, the Smart microchip monitors for over-charge, over-discharge, and over-temperature incidents, logging these events so you can review the battery's history and determine if it's still suitable for use. The protective metal alloy housing helps dissipate heat during high-discharge operations, maintaining safe internal temperatures during demanding flights.
- Is this battery suitable for beginners, or is it only for experienced RC pilots? — This battery is best suited for intermediate to advanced RC enthusiasts who are comfortable with lithium polymer batteries and have appropriate charging equipment. Beginners new to RC should start with ready-to-run kits that include compatible batteries and chargers. However, if you're upgrading from a beginner package and have experience with LiPo batteries, the Smart technology features actually make this battery easier to manage than traditional packs, as the charger handles all the technical settings automatically. Always follow proper LiPo safety procedures including using appropriate chargers and storage containers.
