Antigravity ATX-30 RE-START BatteryAntigravity ATX-30 RE-START Battery

NEW Drop-In Mounting Kits to quickly & easily install the Lithium ATX-30-RS Battery in your sports car, muscle car, or other hi-performance race vehicle.


The Antigravity ATX-30 RE-START lithium battery is very compact, with a much smaller footprint than the original H6/Group-48 lead/acid battery found in your Porsche (or other Hi-Performance Car). But with this Mounting Tray securing the ATX-30, it then directly swaps into any Porsche that uses the “H6” aka “Group 48” size with no need for modifications. This makes the ATX-30 a quick and relatively painless battery swap most anyone can do.

This ATX-30-RS Mounting Kit uses the same stock mounting cleats as your 991.1 or 991.2 or any car using the Group 48/H6 size Battery including GT4s, Boxsters as well as most all other vehicles that use that battery size. Secured within its mounting tray, the ATX-30 becomes a direct swap for the H6/Group 48 battery.

The mounting tray is a CNC’d Aluminum design available in 3 colors: Billet (raw Aluminum) or anodized Black, or Blue. The kit also includes a matching Top Bar, two Support posts, adhesive-backed foam pads and hardware.


This Mounting Kit does NOT include the ATX-30-RS Lithium Battery – you can find that HERE.


The Antigravity BT-H6 Aluminum Battery Tray allows fitment of our ATX-30-RS Lithium-Ion Battery into your vehicle using your vehicle’s OEM mounting system, so basically a Drop-In fit. The BT-H6 Tray (which attaches to the ATX-30) mimics the bottom mounting cleats found on a number of Lead/Acid Batteries sizes listed below.

But it should also be noted that the ATX-30 can potentially be TALLER that some stock batteries listed below due to the necessity of adding our SAE Car Terminal Adapters to the ATX30 to accept Automotive Style Battery Cables. So please check your measurements before purchase. The Automotive SAE Terminal Adapters add 1″ to the height of the ATX30, which alone is 6.5 x 5 x 6.89 inches LxWxH (mm: 165 x 127 x 175).

Side Cleats
If your vehicle mounts using the bottom cleats of your existing Lead/Acid battery from Left to Right (Measurement “A”) then this tray will work with the following Battery size (Most Porsches):

  • H6 same as Group 48

Front/Back Cleats
If your vehicle mounts using the bottom cleats of your existing Lead/Acid battery from Front to Back (Measurement “B”) then this tray will work with a number of Battery sizes:

  • T5 same as Group 96R
  • H6 same as Group 48
  • H7 same as Group 94R

Ultimately this depends on the bottom mounting type in your vehicle, and if your vehicle uses the bottom mounting system, and the height you need to achieve. Please check all measurements before purchase.
