Battery Info

For the do-it-yourself guys, we now offer our high quality battery tray as a stand alone kit. If you would like to use your own battery isolator and do the wiring yourself, or if you have specific needs that our full-featured kit does not meet, now you can get the bare battery tray and top lid alone. This kit comes with no components mounted onto the top lid, but you still get all the hardware you need to install it into your 2007-2020 Toyota Tundra.

The kit includes everything you need to install the tray:

CNC laser cut and CNC bent steel battery tray
Top lid with grommets for routing your wires
Rubber caps over the pressed-in studs - you can use them or remove them
Hardware to secure the top lid
All hardware required to install the tray and move the fuse box backwards
Fits 2007-2021 Toyota Tundra
Uses the factory battery cables - no cutting required
Batteries sold separately. Matching Group 25 batteries are required.
Powder coated for durability
Proudly made in the USA

Follow our detailed instructions for installing the battery tray, then finish it off with your own custom wiring solution.

Battery Options:

Any Group 25 size battery will fit our tray (Note the stock battery is not compatible)
For your convenience, we currently offer the Full River FT750-25, an excellent battery that has 750CCA (cold cranking amps) and 64aH (amp hours) of reserve capacity
The Odyssey Performance Series ODP-AGM25 battery is also available for purchase through our site, boasting 675CCA and 59aH of reserve capacity
Note: Batteries ordered through Genesis Offroad will ship separately
Both batteries must be the same physical size for the top lid to securely hold them in place

Optional Ring Terminals

Are you planning on connecting some accessories to the power & ground bus bars? We offer this convenient 16 piece assortment of high quality, adhesive-lined heat shrink ring terminals. These are much better quality than the cheap ring terminals at the auto parts stores.

Each package Includes 4 each of the following sizes to match the bus bars on the Gen 3 Power Hub.

#10 ring, 16-14ga
1/4" ring, 16-14ga
5/16" ring, 12-10ga
3/8" ring, 12-10ga.

Q: I asked this the other day... Hi, I am looking to add a 100ah lithium battery. The closest size I can find is 10.23 wide 5.23 deep and 8.95 tall. Would this work with a group 25 starter battery on the other side? I'm just looking to keep a refrigerator going. Thanks, Jason To clarify, I'm wondering if the bracket can physically hold these two batteries. I'm looking at the DIY kit. I understand the lithium battery needs a DC to DC charger.

Asked by: Jason - 3/21/2024

A: The battery you're considering is too wide to fit in the tray.

Asked by: Jason - 3/20/2024

A: You cannot mix battery chemistry. Meaning if you use one lithium battery, you must use two. To our knowledge, there is not a proper lithium battery available at this time to use in this kit.

Q: Will this kit fit a 2012 Toyota Sequoia Limited with 5.7 regular fuel V8? Under the hood should be than same as a tundra.

Asked by: Brian Mullins - 1/24/2022

A: This kit has been designed to fit the 2007-2021 Tundra. We have had no customers report any success installing into a Sequoia to date. The cooling system is different, so the radiator support and hoses interfere.
