9000mAh-11.1V speedrun pack. 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 the our 90250-4S2PSQ square pack.
To help us better keep up with demand we are offering these new packs at a 10 dollar per pack discount as a pre-order. First shipment is due in by the second half of September. A pre-order can be cancelled and refunded at any time. Just email us with the order ID number for a refund. Once the first shipment arrives in stock or the amount of packs we have ordered in our first order is sold out we will stop offering the discounted pricing. The goal of this discount and pre-order is to allow us to know the demand for these new packs and place a second order to try and keep up with demand.
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.
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.
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.
- Built with 3omm wide tab cells for lowest possible internal resistance.
- 8AWG wires soldered straight to the tabs for lowest possible resistance.
