Antigravity Foam Kit

Antigravity Batteries Foam Kit (AG-FM-1) | High-Density Battery Spacers

Secure small-case lithium batteries in larger stock battery trays with the Antigravity Foam Kit. Includes adhesive-backed, high-density shock-absorbing foam.

The Antigravity Batteries Foam Kit (Part # AG-FM-1) provides a simple, clean, and vibration-resistant solution for mounting compact, small-case lithium batteries into larger OEM battery compartments. When upgrading to ultra-lightweight lithium motorsport batteries, the significant reduction in physical battery dimensions often leaves excessive space inside standard battery boxes or trays.

Crafted from closed-cell, high-density foam, this kit includes peel-and-stick adhesive backing for instant installation without extra glue or fasteners. The customizable foam blocks are easily trimmed with scissors or a utility knife, allowing custom padding, elevation, or side-bracing. By dampening harsh road vibrations and keeping the battery firmly anchored, the kit prevents terminal strain, mechanical movement, and premature failure in demanding powersport applications.

Best Uses

1. Lithium Battery Upgrades: Installing compact Antigravity Small Case batteries (e.g., 4-Cell, 8-Cell, or 12-Cell) into standard or oversized stock battery trays.
2. Motorsports & Racing: Securing lightweight batteries in track cars, motorcycles, ATVs, and UTVs subject to severe G-forces, jumps, or high-vibration environments.
3. Custom Vehicle Builds: Custom cafe racers, hot rods, or off-road builds requiring modified battery location padding and electrical insulation.

Features

1. High-Density Closed-Cell Foam: High-strength, shock-absorbing material engineered to resist crushing, oil, water, and thermal degradation.
2. Peel-and-Stick Adhesive Backing: Strong self-adhesive layer ensures foam blocks remain firmly affixed to battery trays or battery cases.
3. Easy-to-Trim Material: Smooth closed-cell structure allows custom trimming with standard scissors or a razor knife for a precise fit.
4. Vibration & Impact Absorption: Engineered structure dampens high-frequency chassis vibrations and cushions against rough terrain impacts.
5. Universal Modular Spacers: Comes with multiple pre-cut foam pieces designed for stacking, side-packing, or height adjustment.

Benefits

1. Snug, Factory-Like Fit: Eliminates loose battery motion when converting from heavy lead-acid batteries to compact lithium units.
2. Extends Battery Life: Reduces internal vibration stress on battery cell connections and terminals, preventing electrical disruption and housing damage.
3. Quick & Tool-Free Install: Self-adhesive backing allows direct attachment into the battery tray in minutes.
4. Protects Vehicle Components: Prevents hard plastic battery cases from chafing, rattling, or damaging surrounding tray walls and electrical leads.
5. Cost-Effective Custom Mounting: Removes the need to purchase expensive, vehicle-specific aftermarket mounting brackets or custom battery hold-downs.
