• SRD-V3  7.4V-11000mAh-250C Square Softcase Drag Racing pack

11000mAh-7.4V square pack for drag racing.   

We are offering the first batch of Square SRD-V3 packs at a very special discounted price as the performance didn't turn out as good as expected.   This first shipment will provide the same performance as the SRD-V2 Square packs which are still the strongest packs on the market. Improvements to the formulation will be made but this may take a good amount of time as we must isolate the reason why the results were not as expected.


Our SRD-V3 packs are an evolution of our popular SRD-V2 line of packs.  The cells used in these packs are custom made for us using the most advanced materials which results in reduced voltage drop under load.  We believe these to be the most powerful cells on the market to date.

The SRD-V3 packs are 2P (2 cells in parallel). Contrary to what is being said by some of our competitors and racers the number of cells in parallel has no impact on the voltage drop of the pack unless you add cells to make the pack bigger.    A bigger/heavier pack will have less voltage drop assuming it’s made with the same cells.   Most companies offering drag and speed run packs are just using cells that factories are already using for other applications, and they achieve the voltage drop desired by adding cells in parallel.  SMC is works directly with the factories engineer to design cells at a proper size/weight to optimize voltage drop under load.   The size of a cell can improve the voltage drop under the highest amp loads. 

Our new square Drag cells have an optimized size to reduce voltage drop under high amp loads.  These are built with super wide 30mm tabs to increase the performance of the cells.   Our competitors packs with many cells in parallel are built with cells that have 12mm or 15mm wide tabs.  Having many cell tabs to connect together will result in a decrease in performance. 


To keep the weight as low as possible these are regular softcase packs with a top and bottom G10 protection plate.  To lower the resistance these are built with 8AWG wires and come with no connectors.  We do offer a selection of connectors that can fit the 8AWG wires.

We are now offering the Amass SH8.0 connectors which are the best 8mm connectors on the market.  We offer them in 3 configurations.   Black male/ Red female ,  Red Male/ Black female and black and red females.   We recommend using a male and female on the packs as this will prevent reverse voltage connection.   You can check out the resistance of these connectors versus the QS8 on the SH8.0 connector page by clicking HERE


Due to the extreme nature of speed runs and drag racing please note there is no warranty on these packs.  Each pack is tested prior to shipping to make sure it is free of manufacturing defects.

- Built with 30mm wide tab cells for lowest possible internal resistance.
- 8AWG wires soldered straight to the tabs for lowest possible resistance.
