SPM 7.4V 4000mAh 2S 130C Smart No Prep Drag LiPo Battery: IC5 O-SPMXDRB1

Overview

The Spektrum SPM 7.4V 4000mAh 2S 130C Smart No Prep Drag LiPo Battery represents the pinnacle of performance power for serious RC drag racing enthusiasts across the UK. Designed specifically for 1/10th scale no prep drag racing, this battery delivers the extreme power and consistency that competitive racers demand. The new Spektrum Smart Pro No Prep Series brings industry-leading graphene LiPo battery chemistry to a purpose-built platform that maximises capacity whilst maintaining a lightweight, impact-resistant hardcase shell. Whether you're competing at the track or pushing your drag racing RC car to its limits, this battery is engineered to give you the edge over the competition.

For RC drag racers, power is absolutely key, and the Spektrum Smart Pro No Prep Series batteries deliver exceptional performance in a revolutionary new package. The Pro series design allows significantly more capacity to be squeezed into the LiPo cells, providing larger power ratings compared to similarly sized battery packs from other manufacturers. This means you get more energy, more punch, and more consistent voltage delivery throughout your run. The hardcase shell is engineered to be thinner and more lightweight than traditional designs, yet remains completely rigid, durable, and impact resistant — essential qualities when you're demanding maximum performance from your RC drag racer.

What truly sets this battery apart is the integration of Spektrum Smart Technology. When connected to a Spektrum Smart charger, the battery automatically uploads its unique charging parameters and comprehensive health information from its integrated memory microchip. This intelligent system takes the guesswork out of battery management, making charging simpler and safer whilst optimising the longevity of your investment. The Smart Pro-Series battery practically takes care of itself, automatically discharging to a safe storage voltage after 72 hours of inactivity, ensuring you always have a ready-to-race battery that performs at peak capacity.

Technical Performance

The Spektrum SPM 7.4V 4000mAh 2S 130C Smart No Prep Drag LiPo Battery is engineered to the exacting standards demanded by professional RC drag racing. With a rated capacity of 4000mAh delivered across two cells in series (2S configuration), this battery produces 7.4V nominal voltage with a maximum continuous discharge rate of 130C, delivering an impressive 520 amps of sustained current. This exceptional current delivery is made possible by the advanced graphene LiPo chemistry, which maintains consistently higher voltage output throughout the entire discharge cycle, even under the extreme amperage loads experienced during full-throttle drag racing runs. The battery supports a maximum charge current of 20A with a recommended charge rate of 4A (1C) and can accept up to 5C charge rates for rapid turnaround between races. Physically, the battery measures 96mm in length, 47mm in width, and 25mm in height, with a total weight of 240 grams, fitting within typical 1/10th scale drag racing battery trays whilst delivering superior capacity. The impact-resistant ABS plastic hardcase construction provides durability without excess weight, and the JST-XH balance connector works with both internal balancing circuitry and external balance adapters. All specifications and build quality reflect Spektrum's commitment to producing the finest RC batteries available in the UK market.

Frequently Asked Questions

• Is this battery suitable for my 1/10th scale RC drag racer? — Yes, this battery is specifically designed for 1/10th scale no prep drag racing applications. However, you must verify that your battery tray can accommodate the dimensions of 96mm length, 47mm width, and 25mm height before purchasing to ensure compatibility with your particular drag racing platform.
• What charger do I need for this battery? — This battery is optimised for use with Spektrum Smart chargers, which automatically recognise the battery and upload its unique charging parameters. Compatible Smart chargers include the S2100 G2, S2200 G2, and S450 G2 models. The battery will charge on standard LiPo chargers, but you will miss out on the Smart features and automatic parameter optimisation.
• How fast can I charge this battery? — The battery supports a maximum charge rate of 5C, which equals 20A at full capacity. However, the recommended normal charge rate is 1C (4A) for optimal battery health and longevity. Using the 5C capability allows for super-fast charge times between races without damaging the pack, making it ideal for competitive racing scenarios where quick turnaround is essential.
• What is the difference between this Pro Series battery and Spektrum's G1 and G2 batteries? — The Pro No Prep Series represents an upgrade to standard hardcase surface packs and lives alongside the G1 and G2 battery lines. The Pro Series features specially formulated High Discharge Chemistry designed for drag racing, allowing more capacity to be squeezed into similarly sized cells, delivering larger power ratings. The Pro Series case is thinner and more lightweight whilst remaining rigidly durable, providing the ideal balance of performance and protection for competitive no prep drag racing.
• Will this battery automatically manage itself? — Yes, this is one of the standout features of Spektrum Smart technology. The battery automatically discharges to a safe storage voltage of 3.90V after 72 hours of inactivity, maximising performance and longevity without any user intervention. You can adjust these auto storage settings based on your preferences through your Spektrum Smart charger if desired.
• How will I know if my battery is healthy? — The integrated microchip stores comprehensive data including charging cycles, discharge cycles, battery temperature, internal resistance, and a detailed error log tracking any over-charge, over-discharge, or over-temperature incidents. When you connect the battery to your Smart charger, you can view this information and make informed decisions about battery suitability for critical racing applications.
• What makes the 130C discharge rate important for drag racing? — The 130C continuous discharge rate means this battery can deliver 520 amps of sustained current, providing the extreme power surge essential for competitive drag racing where every fraction of a second counts. This exceptional current delivery, combined with the graphene chemistry's ability to maintain consistent voltage under load, ensures you have maximum acceleration throughout your run.
