Gen 3 Dual Battery System
for 2007 - 2021 Toyota Tundra
Genesis Offroad launched the first completely integrated, easy to install dual battery system for the Jeep Wrangler in 2013. Never satisfied with 'good enough', we have listened to customer feedback and refined our dual battery system to be even better suited to meet the demands of today's off road vehicles and their drivers.
Our purpose remains the same - to allow you to enjoy your aftermarket electrical accessories without worrying about draining down your cranking battery. Even if your cranking battery gets too low to start the engine, simply press a button to jump start from your second battery. Gone are the old days of reading wire schematics to figure out how to add a second battery to your vehicle with a manual selector switch or isolator device. Genesis dual battery kits are completely pre-wired for you out of the box for easy installation. No wire strippers or crimpers required!
What's new with Gen 3
1 - New heavy duty battery combiner
Allows your engine's alternator to charge your cranking and accessory batteries.Connects batteries together in parallel while driving, then separates them once the voltage drops below 12.7v to protect your cranking battery from getting drained by your accessories.Rated for 300 amps continuous current flow, and spikes of up 2500 amps for 10 seconds to handle anything you can throw at it.Compatible with all modern high output alternators.Uses NO power to keep batteries connected, allows batteries to stay fully charged when not in use and run accessories even longer.Generates NO heat, since no current is flowing through it while the batteries are connected, the battery combiner produces no heat at all.More robust and more reliable design means more worry-free adventures
2 - New boost button
Now includes 3 user-selectable modes - Auto, On, and Off'Auto' mode automatically connects batteries when either one is above 13.1v for 90 seconds, and disconnects them when they drop below 12.7v for 30 seconds.'On' mode will manually connect the batteries together. Use this to jump start the engine when the cranking battery is low, or manually provide extra run time to your accessories by using both batteries together.'Off' mode will manually separate the batteries. Use this when you want to leave the batteries isolated for any reason. Note the alternator will not charge the Aux battery while in this mode.The green halo light will turn on to indicate the batteries are connected, and the light will be off when the batteries are separated.3 - New bus bars
Now includes 3 tall studs and 3 small screws for power & ground wire connectionsDifferent stud sizes 1/4", 5/16", and 3/8" give you more flexibility for connecting your heavy duty accessory cables such as a winch, stereo amplifier, air compressor, fuse panels, etc.Lighter gauge wires such as LED lights, CB, etc, can use the 3 small screws for connecting #10 sized ring terminals.Any accessories connected to the bus bars will run from the Aux battery and will not drain down the cranking battery.The protective cover flips up for easy access for routing your wires.
4 - New Heavy Duty Cables
Higher solid copper strand count for more current carrying capacity and more flexibilityThicker insulating jacket for even more protection from the elementsHeavy duty adhesive lined heat shrink protects the wire from corrosionTin-plated copper lugs and post clamps for superior conductivity

Durable
Size: Large
Excellent material. I wish the hole was a little smaller to keep the treats in better. Also wish they were a little larger and/or oddly shaped so as not to fit under the sofa. Still totally worth it.

Subtle, great dog toy design!
Size: Large
These things are amazing. Stuff them with peanut butter and treats and freeze them of course, but football spike them across the yard to drive your overly hyped dog nuts! And the hole allows you to safely pry it out of a tug battle , just a great design! And it can bobble across a small living space without getting lost like a ball would. Love it!

Treats fall out way to easy
Size: Large
Kinda sorta awful at holding treats in it, they just fall out without my dog even having to touch it really. I spread peanut butter on the inside of the toy and freeze it..works much better that way, nay, works amazing that way. I got this toy to stimulate his brain, so he’s either much smarter than every other dog or the treats fall out too easy..I believe it’s the ladder.

Great for enrichment treats for dogs
Size: Large, Size: Large
Great product and durable. We fill them with wet dog food and freeze it then give it to our dogs as enrichment treats. They love it. It’s super easy to use and strong against dogs bites and chewing

Keeps My Dog Busy and Happy!
Size: Large
I bought this 2-pack of treat-dispensing toys for my large dog, and they’ve been a total win. The rubber is strong enough to hold up against heavy chewing, but soft enough that it doesn’t hurt his teeth. I like that it’s large, so I can fill it with kibble or small training treats, and it keeps him entertained for a long time.
The best part is how much mental stimulation it gives—he really has to work to get the treats out, which helps with his energy and boredom. I also noticed it slows down his eating when I use it for kibble, which is a huge bonus since he usually gulps food too quickly.
Getting two in a pack is great value. I keep one stuffed in the freezer with peanut butter for a cool snack on hot days and use the other for everyday play. Both clean easily with warm water and soap.
✅ Durable and safe rubber
✅ Keeps dogs busy and mentally stimulated
✅ Doubles as a slow feeder
✅ Great value for a 2-pack
Highly recommend if you want something affordable, durable, and actually fun for your dog!
