👉 The DDR fluid, or Deep Cycle Absorbent Diaphragm Pump Fluid, is a specialized lubricant and absorbent material used in deep cycle electric vehicles (EVs) and other applications involving rechargeable batteries. It serves as a critical component in the battery management system, providing cushioning and reducing friction between moving parts within the battery pack. This fluid also helps absorb shocks and vibrations, ensuring smoother operation and extending the lifespan of the battery and its components. Composed of a mixture of silicone oil and various additives, DDR fluid is designed to maintain optimal performance under the demanding conditions of deep cycle applications, where the battery is frequently charged and discharged.
