Hcl-rs 7. 4v-4800mah-150c lcg 21mm shorty 5mm inboard hardcase. Roar approed this pack is perfect for stock racing where our 5600 pack is to heavy to make legal weight and our 4000-lcg pack is a bit to light. Introducing the hcl-rs line of race packs (high cycle life - race series). These formulations are not the generic cells/packs you can get with different color stickers on them. These are recipes developed for us by an independent factory. While we have recently pushed mah and c rates for applications like flight packs and speed run packs, the demands of racing are different. These new formulations hold better voltage, sag less under loads seen in off and on road racing by optimizing the ir and mah per cubic centimeter of the cells.
