This means you can spend less time fiddling with charger settings and more time enjoying your RC car, truck, boat or other vehicle. The impact-resistant ABS plastic hardcase protects your investment during transport and use, whilst the advanced IC5 connector ensures a secure, reliable power connection that's backwards compatible with existing EC5 equipment.
UK RC enthusiasts appreciate batteries that offer both performance and convenience, and this Spektrum Smart pack delivers on both fronts. The 100C discharge rating ensures your RC car or boat gets instant throttle response and maximum power delivery exactly when you need it, whilst the Smart technology features mean your battery practically takes care of itself. With automatic self-discharge to storage voltage, temperature monitoring, and detailed error logging, you can be confident your battery will serve you well for years to come.
Key Features
- Integrated Smart Microchip — Each battery contains a memory microchip that stores unique parameters including battery brand, type, capacity, C rating, cell voltage, temperature data, and charge/discharge cycle count. This allows your Spektrum Smart charger to automatically recognise the battery and recall your preferred settings, eliminating manual configuration and ensuring optimal charging every single time.
- Smart Discharge Technology — Programmable automatic discharge brings your battery to safe storage voltage between 12 and 240 hours after use, preventing the damage caused by storing fully charged LiPo cells for extended periods. This exclusive feature dramatically extends battery lifespan and maintains consistent performance throughout the battery's life, ultimately saving you money on replacement packs.
- 100C Continuous Discharge Rating — The powerful 100C rating delivers maximum sustained current output, giving your RC car, truck, or boat the instant acceleration, responsive throttle feel, and peak performance you demand. Whether you're competing in time trials or enjoying recreational bashing, this high discharge rate ensures your battery can handle the demands of high-performance brushless systems.
- Impact-Resistant Hardcase Protection — Unlike soft-case batteries that deform and lose rigidity over time, the ABS plastic hardcase keeps your battery protected from impacts, maintains consistent shape, and ensures it fits perfectly in your RC vehicle's battery compartment. The hardcase also helps protect the sensitive internal cells from physical damage during transport and storage.
- IC5 Connector with Smart Data Wire — The next-generation IC5 connector is larger and more robust than older connector types, offering superior heat resistance and effortless installation. The integrated data transfer wire communicates battery information to your Smart charger, whilst remaining fully backwards compatible with existing EC5 equipment, so you're not locked into replacing your current chargers immediately.
- No Soldering Required — This battery arrives factory-assembled with connectors already installed, meaning you can unbox it and start charging and using it straight away. No special tools, no technical knowledge, and no soldering experience required—perfect for both beginners discovering RC vehicles and experienced pilots who value convenience.
- Comprehensive Error Logging — The battery automatically tracks unhealthy events including over-charge, over-discharge, and over-temperature incidents. This error log helps you make informed decisions about battery health and usage, and provides diagnostic information if issues ever arise, giving you complete confidence in your equipment.
- Data-Rich Battery Memory — Beyond basic specs, the microchip records detailed information including internal resistance, individual cell voltage, battery temperature during use, and the number of complete charging and discharging cycles. This wealth of data helps you optimise charging rates and understand battery condition at a glance.
Technical Performance
The SPM 5000mAh 4S 14.8V 100C Smart LiPo Hardcase represents the pinnacle of lithium polymer battery engineering. With four series cells delivering 14.8 volts nominal output, this pack provides the ideal voltage for high-performance RC cars, trucks, buggies, and boats that demand responsive power delivery.

Frequently Asked Questions
- Is this Spektrum Smart battery compatible with my existing charger? — The IC5 connector is fully backwards compatible with older EC5 equipment, so you can use this battery with non-Smart chargers if needed. However, you'll only unlock the full benefits—including automatic charge settings, smart discharge programming, and detailed battery data—when using a compatible Spektrum Smart charger. We recommend upgrading to a Smart charger to get maximum value from this intelligent battery.
- What does the 100C discharge rating mean for my RC car or boat? — The 100C rating indicates this battery can safely deliver 500 amps of continuous current (100 multiplied by 5 amps per mAh capacity). This enormous current capacity makes it ideal for high-performance brushless systems that demand instant throttle response and maximum acceleration. For comparison, lower C-rated batteries in the same capacity will limit your vehicle's performance and may cause voltage sag during hard acceleration.
- How does Smart discharge extend my battery's life? — Lithium polymer cells suffer permanent damage when stored fully charged for extended periods. The Smart discharge feature automatically brings your battery down to safe 3.0V per-cell storage voltage (11.2V total for 4S) within your programmed timeframe, preventing this chemical degradation. Users report significantly longer usable lifespan when batteries are properly stored at safe voltages compared to batteries left fully charged between uses.
- What is the maximum charge rate for this battery? — This battery supports a maximum charge rate of 3C, which equals 15 amps for the 5000mAh capacity. Charging at the full 3C rate will charge the battery completely in roughly 20 minutes, though you can charge more slowly if preferred. Always use a quality charger with appropriate amperage capacity and never attempt to charge at rates exceeding the manufacturer's specification.
- Will this battery fit in my RC vehicle? — The battery dimensions of 138mm length × 47mm width × 40mm height make it suitable for most modern 1/10 scale RC cars, buggies, and boats designed for 4S LiPo batteries. Before purchasing, check your vehicle's battery compartment dimensions to confirm compatibility. Most modern RC vehicles from Traxxas, ARRMA, Losi, and other major manufacturers offer battery compartments sized for standard 4S hardcase packs like this one.
- What does the error log tell me about battery health? — The integrated error log tracks over-charge, over-discharge, and over-temperature events. If you notice an increasing number of over-temperature incidents, for example, this might indicate your vehicle's ESC is drawing too much current, or your charger settings are too aggressive. Over-discharge events suggest you're running the battery completely flat, which damages LiPo cells—consider charging before your battery voltage drops below 3.0V per cell (12.0V total for 4S).
- Is this suitable for beginners? — Absolutely. Whilst the Spektrum Smart technology offers advanced features that experienced pilots will appreciate, the battery itself is straightforward to use. Factory assembly means no soldering or technical knowledge is required, and the IC5 connector plugs in securely. Beginners will benefit from simplified charging with a Smart charger and don't need to understand the microchip features to enjoy reliable performance. Just remember to charge properly and store at safe voltage between uses.
- What makes this better than a standard LiPo battery? — Three key advantages: First, the microchip automatically communicates with Smart chargers, eliminating manual setup and ensuring optimal charging parameters every time. Second, smart discharge programming maintains your battery at safe storage voltage, dramatically extending lifespan. Third, the detailed error log and performance data let you understand battery condition and optimise your vehicle setup. A standard LiPo offers basic power, but this Spektrum Smart pack offers intelligence, convenience, and longevity.
