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!

Frequently Asked Questions
- Is the Spektrum 11.1V 14000mAh 3S 120C Smart Pro Basher LiPo suitable for ARRMA Infraction and Felony models? — Yes, this battery is specifically engineered to fit ARRMA 6S all-road models including the INFRACTION and FELONY. It also works with ARRMA 8S BLX models such as KRATON and OUTCAST 8S. Always check your vehicle's battery tray dimensions to confirm compatibility before purchase.
- What makes the 120C discharge rate important for RC bashing? — The 120C discharge rate means this battery can safely deliver extreme amperage to your brushless motor and ESC without thermal stress or voltage sag. This translates to more consistent power delivery, faster acceleration, and better sustained performance during aggressive bashing. The 120C rating is specifically designed for high-demand basher applications rather than slower crawling or racing.
- Do I need a Spektrum Smart charger to use this battery? — Whilst this battery can technically be charged with standard LiPo chargers, you'll only unlock its full potential—including automatic charging, health monitoring, and Auto Storage Discharge—when used with a Spektrum Smart charger. The Smart charger system significantly simplifies battery management and maximises pack longevity.
- How long does the Spektrum Smart battery take to charge? — With a 5C maximum charge rate (70A), this 14000mAh battery can charge extremely quickly. At the standard 1C rate (14A), full charging takes approximately 10 hours. At the maximum 5C rate, charging times are dramatically reduced, making this ideal for users who want fast turnaround between bashing sessions.
- What is the difference between this Pro Basher Series battery and standard Spektrum Smart batteries? — The Pro Basher Series features a newly designed thinner hardcase that allows more mAh capacity to be squeezed into a basher-friendly form factor, compared to standard Smart G1 and G2 batteries. The Pro Series also benefits from advanced Graphene LiPo chemistry, improved case durability for impact resistance, and optimised performance parameters specifically tuned for high-discharge bashing applications.
- How does Spektrum Smart Battery Technology actually work? — Each Smart battery contains an integrated microchip that communicates with compatible Spektrum Smart chargers via the IC5 connector's data wire. The microchip stores battery specifications, charging history, temperature data, cycle count, and error logs. When you connect the battery to a Smart charger, all this information uploads automatically, enabling the charger to apply perfect charging parameters without any manual setup required from you.
- What happens if my battery is left unused for a long time? — The Auto Storage Discharge function automatically discharges the battery to a safe storage voltage of 3.90V per cell after 72 hours of inactivity. This is particularly important for LiPo longevity, as cells stored at full charge degrade faster. You can adjust these Auto Storage settings through your Smart charger if you prefer different discharge timing.
- What safety features does this battery include? — This battery includes integrated charge protection circuitry, integrated balancing with internal balancer and internal adapter, and an error log that records over-charge, over-discharge, and over-temperature incidents. The memory microchip allows you to review these events and make informed decisions about battery suitability for specific applications.
- Can I use this battery in vehicles other than ARRMA? — Whilst this battery is optimised for ARRMA 6S and 8S models, the IC5 connector and 11.1V specification mean it can work in other compatible vehicles using 3S LiPo batteries with IC5 connectors. Always verify battery tray dimensions and connector compatibility before purchasing, as the Pro Basher's larger capacity may not fit all vehicles.
- Is this battery good value for money? — This represents outstanding value for serious RC bashers. The 14000mAh capacity, 120C discharge rate, advanced Graphene chemistry, and comprehensive Smart Battery Technology system typically found in premium batteries are all included. The Auto Storage Discharge and intelligent monitoring system also extend battery lifespan, meaning you'll keep this pack running reliably for many more cycles than budget alternatives.
