Step 9: Layer Plastic Sheeting Inside Box (optional for AGM or LiFePO4 batteries)
SMALL BATTERY BOX INSTALL
To install them, we used a piece of ¼” plywood as a spacer, Titebond II wood glue, and ¾” self-tapping screws. Two D-ring anchor points inside the battery box (one on the front and one on the back) let us strap our batteries down. Step 8: Install Anchor Points for Ratchet Straps We also drilled holes about halfway down on the left side (the side closest to the rest of the electrical components) to run our wiring through. We drilled holes right at the top of the angled side pieces and three more holes along the top of the back piece to let any released hydrogen rise up and escape (this is very unlikely with AGM batteries). The front of the battery box got four holes a few inches down to allow for fresh air to flow in. Step 6: Make Sure the Batteries Fitĭry-fitting the batteries proves that we didn’t screw up any of our measurements! Step 7: Drill Holes for Vents and Wiringįor ventilation, we drilled several holes in the front, sides, and back of the battery box using a 1-½” spade drill bit (a hole saw would work too). Once the spacer was set in place inside the battery box, we permanently attached it using 1” GRK cabinet screws driven in from the outside. The spacer fits perfectly in the bottom of our battery box. So, we made a spacer out of 1×3 furring strips arranged into a square and attached together using pocket holes and 1-¼” pocket hole screws. Since we designed our battery box with some wiggle room to allow for airflow, we needed a way to keep the batteries in place inside the box. And because our batteries are a weird size, we couldn’t find any commercially available battery boxes that would fit them. Some may argue that a battery box is unnecessary for AGM batteries, but we just felt safer having one.
SMALL BATTERY BOX UPGRADE
*New* Optional Upgrade to Titanium Tiedown.Titanium flange nuts and rods for easy installation and removal of the battery.The kit includes all necessary titanium hardware for a simple, bolt-in install to factory mounting points, with no drilling necessary.

Each of our battery trays is laser cut from 6061 aluminum and black anodized for a durable, long-lasting finish. The JDC Small Battery Kit for Mitsubishi Evolution 7/8/9 is a great upgrade for anyone looking to shed some extra weight or make some room for a more direct route upper intercooler piping.
