SRD-V2 Drag and Speedrun Packs
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.
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.
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.
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.
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 it out to make sure it is free of manufacturing defects.
