The Best for Backyard Bashing
SpektrumT 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 SPM 14.8V 6800mAh 4S 120C Smart G2 Pro Basher LiPo battery represents a quantum leap forward in power delivery engineering for high-performance RC bashers in the UK market. At 650 grams, this battery packs serious capacity into a manageable weight, with dimensions of 157mm length, 48mm width, and 41mm height—perfectly proportioned to fit large-format bashers like the ARRMA KRATON and OUTCAST 8S without sacrificing chassis real estate. The four-cell (4S) configuration delivers 14.8V nominal voltage, providing the elevated power required for modern brushless ESC and motor combinations whilst remaining within the compatibility window of high-performance basher vehicles. The 120C discharge rating represents the absolute pinnacle of discharge performance, translating to 816 amps of maximum continuous discharge current—an extraordinary figure that ensures zero voltage sag even during the most punishing acceleration and cornering loads. The Pro Basher Series' advanced graphene chemistry achieves a remarkable feat: consistently higher average discharge voltage across the entire battery curve, meaning you maintain near-peak power from first punch to final run-down. The maximum 5C charge rate capability permits super-fast charging with a 34A charge current (6.8A standard charge current), allowing even rapid turnarounds between multiple bashing sessions without degrading cell health. The internal balanced flat-cell architecture, combined with the thin-walled polycarbonate hardcase, demonstrates Spektrum's commitment to engineering solutions that maximise usable capacity without compromising durability—crucial for serious bashers who demand their equipment survive the most aggressive terrain and driving styles.

Frequently Asked Questions
- Is the Spektrum Smart G2 Pro Basher battery suitable for high-performance RC bashers in the UK? — Absolutely. This battery is specifically engineered for extreme performance in surface basher vehicles. The 120C discharge rate, 6800mAh capacity, and graphene chemistry make it ideal for ARRMA 8S BLX models such as the KRATON and OUTCAST, as well as other high-performance brushless basher platforms. If you're serious about bashing and demand maximum power and run time, this is precisely the battery you need.
- What makes the Spektrum Smart technology worth the investment? — Spektrum Smart batteries integrate an intelligent microchip that automatically communicates with Spektrum Smart chargers, uploading unique charging parameters and health information. This eliminates manual configuration, ensures optimal charging every time, automatically balances cells, and automatically discharges to safe storage voltage after 72 hours—all without user intervention. The battery essentially manages its own health and longevity, making it genuinely maintenance-free compared to standard LiPo batteries.
- How long will this battery last on a single charge? — Run time depends entirely on your specific vehicle, driving style, motor KV rating, and ESC settings. However, the 6800mAh capacity is substantially larger than typical surface basher batteries, delivering significantly extended run time compared to smaller packs. Most bashers report that this capacity extension allows for considerably longer sessions between charging.
- Can I use this battery with my existing charger? — Whilst this battery has charge protection circuitry and can technically charge on standard LiPo chargers, you'll miss out on the intelligent Smart technology benefits. To take full advantage of automatic charging, health monitoring, data logging, and customisable parameters, you'll need a Spektrum Smart charger. The investment in a Smart charger pairs perfectly with this Smart battery for the ultimate hassle-free charging experience.
- What is the difference between the G2 Pro Basher and other Spektrum Smart batteries? — The Pro Basher Series represents Spektrum's premium offering for bashers demanding maximum capacity and power. Compared to standard Smart G1 and G2 surface batteries, the Pro Basher features higher mAh capacity in the same footprint, the newly designed thinner hardcase, and graphene chemistry optimised specifically for extreme discharge applications. The 120C discharge rate is substantially higher than most other offerings, and the flat cell configuration maximises chassis space—making this the ultimate choice for serious bashers.
- Is this battery compatible with my ARRMA 8S vehicle? — Yes, this battery is specifically listed by Spektrum as compatible with ARRMA 8S BLX models including the KRATON and OUTCAST 8S. However, always verify that your vehicle's battery tray can physically accommodate the 157mm length, 48mm width, and 41mm height dimensions before purchase. Most modern ARRMA bashers have no compatibility issues with this pack.
- What does the 120C rating actually mean for my bashing? — The 120C discharge rating means this battery can safely discharge at 120 times its capacity per hour (120 × 6.8A = 816A maximum continuous discharge). In practical terms, this means you get lightning-fast acceleration, no voltage sag under extreme load, and maximum power delivery to your motor even during the most aggressive driving. This is essential for competitive bashers and anyone pushing high-KV brushless motors to the limit.
- How does the graphene chemistry improve performance? — Graphene-enhanced LiPo cells maintain higher average voltage throughout the entire discharge curve compared to conventional chemistry, resulting in less voltage sag under high amperage loads. This means your motor receives more consistent power from start to finish, translating to faster acceleration, better top speed maintenance, and improved overall performance throughout your entire bashing session.
