We are pleased to offer a new line up of speed run and drag racing packs. These use our new True Spec Extreme Graphene V2 formulation which you can read up on by clicking here. These packs have been designed to optimize power to weight ratio. These packs have the highest possible performance in the market based on their weight/size to power ratio. If you are serious about speed runs or drag racing then these are must have packs.
To keep the weight as low as possible these are regular softcase packs with no G10 protection plates. To lower the resistance these have 8AWG wires and come with no connectors. We do offer connectors in the drop down menu but many who do speed runs/drag racing tend to use different connectors.
Click here to see how our 6400 packs did under 12 cycles at 300A discharge. First graph is the data at 250A before the 12 cycles at 300A and second graph is he data at 250A after the 12 cycles. This shows how advanced materials give better performance and improves cycle life.
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 out to make sure it is free of manufacturing defects.
- Built with wide tab cells for lowest possible internal resistance.
- 8AWG wires soldered straight to the tabs for lowest possible resistance.
