The Best for Backyard Bashing
Spektrum™ Smart Technology is proud to introduce our lineup of Smart LiPo batteries with specially formulated Graphene LiPo High Discharge Chemistry designed to provide consistently higher voltage throughout the entire run of the battery under even the most extreme amperage loads.
For RC Bashers, maximum capacity and power are key, and the new Spektrum Smart Pro Basher Series batteries deliver! The Pro series batteries allow for more capacity to be squeezed into the LiPo cells, allowing for larger mAh ratings when compared to similarly sized battery packs. The Pro Basher Series features a newly designed hardcase shell that is thinner and more lightweight, all the while staying rigid, durable, and impact resistant. This series lives alongside current Smart G1 and G2 batteries and is an upgrade to standard hardcase surface packs.
Smart Pro-Series battery's benefits include longer battery life, better performance over the life of the pack, and the peace of mind that comes from knowing your Smart battery is maintenance-free.
When a Smart Pro-Series battery is connected to a Spektrum Smart charger, its unique charging parameters and health information are uploaded to the charger from its integrated memory microchip. You can view and set preferences through the charger, such as charge rates, so all that's required to charge the pack is connecting it to your Smart charger. Smart technology takes care of the rest.
Spektrum Smart Pro-Series surface batteries store a wide variety of essential information, including:
- Battery Brand
- Battery Type
- Battery Capacity
- Battery C Rating
- Individual Cell Voltage
- Battery Temperature
- Charge/Discharge Cycles
Spektrum Smart Pro-Series surface batteries also maintain an error log, including over-heat, over-discharge, and over-charge incidents. This data can help assure that the battery you've chosen is suitable for the application.
Innovative Spektrum Smart Pro-Series surface batteries are so easy to use that they nearly take care of themselves. Smart technology makes it easy to achieve peak battery performance, reliability, and longevity!

Technical Performance
The Spektrum 14.8V 10000mAh 4S 120C Smart G2 Pro Basher LiPo battery is an engineering triumph that combines cutting-edge materials science with intelligent electronics integration. At 14.8V nominal voltage (3.7V per cell across four cells), this pack delivers the power envelope required by modern brushless RC bashers whilst remaining compatible with the latest ARRMA platforms and other high-performance surface RC vehicles. The 120C continuous discharge rate is genuinely impressive, allowing peak discharge currents of 1,200 amps when required—this is the kind of performance specification that separates serious competition-grade batteries from consumer-level alternatives. Weighing 1040 grams (36.68 ounces) with dimensions of 178mm length, 52mm width, and 52mm height, the pack is engineered to fit standard battery trays across multiple vehicle platforms whilst remaining compact enough for quick changes during competitive sessions. The graphene polymer chemistry represents the latest advancement in lithium polymer cell formulation, delivering superior voltage stability under load compared to conventional LiPo chemistry. This means less voltage sag during acceleration, more consistent power delivery throughout your run, and ultimately faster lap times and more aggressive performance across the entire discharge cycle. The 5C charge rate capability (50A maximum charge current) is particularly valuable for serious bashers who need quick turnaround times between runs, allowing full recharge in under 20 minutes depending on charger capabilities. The internal balancing system with integrated adapter ensures that all four cells remain perfectly matched, preventing the voltage imbalances that can degrade battery life or cause performance issues. Combined with Spektrum's proven Smart technology platform, this battery represents a genuine step forward in RC battery intelligence and reliability.

Frequently Asked Questions
- Is the Spektrum Smart G2 Pro Basher 14.8V battery compatible with my ARRMA RC vehicle? — Yes, this 14.8V 4S battery is specifically designed to fit ARRMA 6S All-Road models such as the INFRACTION and FELONY, as well as ARRMA 8S BLX models including the KRATON 8S. Always check your specific vehicle's battery tray dimensions to confirm compatibility before purchase.
- What makes the 120C discharge rating so important for RC bashing? — The 120C rating means this battery can safely deliver continuous currents up to 1,200 amps, providing the raw power needed for aggressive acceleration, high-speed running, and hard cornering without voltage sag. This results in faster acceleration, higher top speeds, and more responsive vehicle control—exactly what competitive bashers need.
- How does Spektrum Smart technology make charging easier? — When connected to a Spektrum Smart charger, the battery's integrated microchip automatically uploads all charging parameters and health information, meaning the charger automatically applies the correct settings without any manual input required. Charging begins automatically and safely—you simply plug it in and let the system do the work.
- What does the 5C charge rate mean and why is it beneficial? — The 5C maximum charge rate means you can recharge this 10000mAh battery at up to 50 amps (5 × 10000mAh = 50A), allowing full recharge from depleted to full in approximately 20 minutes or less depending on your charger. This rapid charging capability keeps you in the action longer and reduces downtime between races or bashing sessions.
- Will this battery work with my existing RC charger? — This battery is optimised for use with Spektrum Smart chargers, which automatically recognise and apply perfect charging parameters. However, the IC5 connector is industry-standard, so it may be compatible with other high-capacity chargers that support 4S LiPo and IC5 connectors—check your charger's specifications to confirm.
- How does the auto storage discharge feature work? — After 72 hours of inactivity, the battery automatically discharges to a safe storage voltage of 3.90V per cell, which is the ideal voltage for long-term lithium polymer storage. This prevents the battery degradation that occurs when LiPo batteries are left fully charged, extending overall battery lifespan significantly. Users can adjust this setting through their Spektrum Smart charger if preferred.
- What is the difference between the Pro Basher series and earlier Spektrum battery generations? — The Pro Basher Series features the new graphene LiPo chemistry that delivers higher average discharge voltage throughout the entire run, a thinner and lighter hardcase design that allows more capacity in a compact form factor, and improved internal balancing. These batteries represent a genuine upgrade to standard hardcase surface packs with longer battery life, better performance, and superior overall reliability.
- Is this battery suitable for beginners in RC bashing? — This is a premium performance battery best suited to experienced RC enthusiasts who understand LiPo safety protocols and have appropriate charging equipment. The high capacity and powerful discharge rating make it ideal for competitive bashers, but beginners might consider starting with a lower-capacity battery and building up experience before investing in this level of performance.
- How long will the battery last if I charge it regularly? — Spektrum Smart batteries maintain detailed cycle logs and provide extended lifespan through intelligent balancing and storage discharge management. With proper care, regular charging through a Smart charger, and adherence to LiPo safety guidelines, this battery will provide consistent performance across hundreds of charge cycles.
