• SRD-V2 14.8V-8600mAh-250C  Speedrun pack

8600mAh-14.8V  speedrun pack.  Please note the mAh has been revised and lowered as the original mAh was estimated.  Please check the size of the pack as these will fit in cars using standard battery trays that are wide enough to allow these packs to fit.  The width of this pack is 51mm. For those running custom graphite chassis check out our 90250-4S2PSQ square pack.

 

Our SRD-V2 packs are an evolution of our popular SRD 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-V2 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. 


We are offering a 3S and 4S Speedrun pack using traditonal longer/narrower cells so they can fit the stock battery compartments.  For those running custom graphite chassis you can check out the Square 4S2P pack as we are using the square drag cells to build these 4S2P packs to minimize the voltage drop as much as possible.


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.

 

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.



- 8AWG wires soldered straight to the tabs for lowest possible resistance.
