Kozmic Ralliart Lithium Small Battery System

Upgrade the battery setup in your 2008–2015 Mitsubishi Ralliart with a compact, purpose-built mount system designed around the Antigravity ATX20 battery line. This kit was created to solve a real fitment problem for turbo-swapped Ralliarts using Evo X-style turbo kits and ETS intake systems—while also being a clean, lightweight, high-quality solution for any Ralliart owner wanting a smaller, stronger battery package.
Built in the USA using a laser-cut and CNC-bent aluminum holder, this setup gives you a secure, professional install with the durability to match serious daily use and track abuse. Whether you’re tidying up the bay, freeing up space, or finishing off a turbo swap the right way, this kit is the cleanest way to mount an ATX20 in your Ralliart.

Optional ETS Intake Support Bracket Kit (Turbo Swap Friendly)
For customers running an Evo X fitment turbo kit on a swapped Ralliart, we also offer an optional intake support bracket kit to properly support an ETS Evo X Intake.
Supports ETS Evo X intake setups with:
Standard MAF Housing
3.5” MAF Housing
This was the main reason this kit was created—because the turbo-swapped Ralliart crowd deserves parts that actually fit and mount correctly, without sketchy DIY brackets or “kinda works” solutions.
⚠️ Fitment Note: ETS Evo X intake setups do NOT fit the OEM Ralliart turbo configuration.
