Group 51R Lithium-Ion Battery

The Antigravity Group-51R Lithium Car Battery is engineered as an intelligent, direct-fit replacement for your vehicle's original battery. It utilizes advanced LiFePO4 lithium chemistry and incorporates a full Battery Management System (BMS) that protects against over-discharge, over-charge, and short circuits, while also providing cell balancing and thermal protection. This ensures maximum safety and extends the battery's lifespan, with expected cycle life of 7-9 years. A standout feature is the proprietary RE-START Technology, which includes built-in wireless jump-starting. If the battery is discharged, you can activate the jump-start function remotely via the included keyfob, allowing you to start your car and drive away without needing external assistance or even opening the hood. This technology intelligently manages power to prevent a complete discharge while retaining enough energy for a restart. In addition to its advanced features, the AG-51R-RS offers significant performance benefits through extreme weight reduction. Weighing in at only 11.25 lbs (for the 30Ah model), it can reduce vehicle weight by up to 40 lbs compared to traditional lead-acid batteries. This weight loss positively impacts handling, braking, and acceleration. The battery provides robust cranking power, with the 30Ah model delivering 1200 CA, capable of starting high-performance motors. This battery is designed to fit in the OEM Group 51R case size (9.4 x 5.2 x 8.6 inches), making installation straightforward without requiring modifications. It is listed as OE S2000 fitment and is also suitable for other performance vehicles that use the Group 51R size, such as Honda Civics, Honda S2000s, Miata MX-5s, and Nissan GTRs. For optimal performance and longevity, it is recommended to use only Lithium LiFePO4 chargers.
