The STM lightweight small battery kit for Evo 7/8/9 allows you to drop 21 pounds vs the factory battery, lightens up the front of the car and clears room in the engine bay for new intercooler piping. The STM tray is machined billet aluminum with stainless hardware and mounts to existing points in the chassis for an easy install.
The battery tray is available without a battery or with your choice of the Odyssey PC680 or the black Genesis 16EP and the batteries will include a set of new terminals. Please note we cannot ship batteries outside the continental USA.

Performance Notes and Warranty:
These small battery kits are used for racing! They are not designed for for an average daily driver and would absolutely NOT support any sort of aftermarket stereo and they are not great in cold temperatures. These batteries are not even intended for automotive use, but we and most of the racing community use them as such. STM does not warranty batteries. We offer the STM Lifetime Guarantee on the STM Battery Tray, but we cannot warranty the batteries themselves as we are all using them in a way they were not intended for and any attempt we have made to have them warrantied by the manufacturer has been denied.
The typical life we get from one of these batteries varies from 1 year to 10 years. Expect to treat this battery as a maintenance item – once it’s done, just get a new one. For a typical 300-600 HP street car, it’s fine to sit for a week, drive and race on the weekends or drive everyday in nice temperatures (40-90°). If it sits longer than 2 weeks or if it’s in freezing temps, we recommend keeping the charger handy.
These batteries will start your car with no problems and charge naturally with a working alternator, but if you’re having ignition issues… in our experience you’ll get about 10-15 attempts off a small battery before it starts to fade if it’s fully charged. If it’s been sitting untouched in a cold garage for 2 months, don’t even bother trying, put it on a charger first.
What’s the difference between the Odyssey and the Genesis? Typically the Odyssey battery has a longer lifespan than the Genesis. Otherwise, it honestly comes down to cosmetics… That red-orange battery top looks terrible in a blacked-out engine bay. The choice is yours. Read more about each battery:
