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.

 

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