Off-GRID ENGINEERING Dual Battery Systems (An Introduction)

[Off-Grid Engineering]

Clean work! Way better than the Columbia Overland tray I have for my first Gen Taco. Do you have a web site yet or just the FB page?

Thanks! We do have website... but its my first attempt at building one so its not super fancy... check it out!

Count me in for 2nd gen tundra interest.

They Matt! I live in Frisco and have been wondering about a secondary battery mount for my T100. Any chance this fits?

 

[Off-Grid Engineering]

Will do!

I haven't had a chance to check! If you're ever in the Northern Colorado area, feel free to stop in and we'll check. I give decent discounts to test trucks!

Outstanding design! I'll definitely have to pick one of those up for my 2nd gen, and maybe some help with wiring. There are many things I'm good at, and electricity is not one of them.

Looks great! I too immediately envisioned a short with the strap, you can't protect against stupid and lots of OEM are metal, but the OEM are lots narrower, and presumably their lawyers have deeper pockets
What about blowing the same strap out of a non conductive fiber board?, rivet a aluminum channel on the back if it's not stiff enuff. I get you have to keep it simple to clear a profit, but industrial DC is my background and I get paranoid
Not trying to rain on your parade, just wasn't looking to see something go bad.

If you're serious about wanting one, please email me at Matt@offgrid4x4.com and we'll get you set up asap! I have quite a few trays ready to go out the door. Just let me know!

Hmmm... I appreciate all the concern. Contact between those two pieces would be very bad. Ive had my system installed for quite some time and have never had the battery or tiedown move... but then again, Im always under the hood designing new stuff. So, Im always checking.

All the other trays on the market have a similar design. Usually they're made out of steel though.

I guess I have to leave it up to the customer to make sure their connections are tight and covered. There are lots of mods we make to our trucks that take individual engineering and forethought to make sure they're safe.


Edit: I just thought of something. I may include some rubber strips to affix to either side of the tie down... for extra insurance. What does everyone think?

I live in Vail and have a 1st gen Tundy DC that needs a dual set up but also want to put an ARB compressor in the engine bay maybe we can come up with a solution for both?!

It's definitely something I'm thinking about doing, but I have a few things I need to take care of first. Nice truck btw. Other than color, we will soon be twinsies.

Looks good. Another vote for 2014+ Tundra!

Anything will help, maybe slit a piece of rubber tube and put it on the edge??. The whole battery box and retaining rods and strap are one big negative, so it's really contact with the red positive post that is a concern. That's what Stoffregen was referring to.

Oh. I totally understand what he was saying. And I agree. If the battery came loose and touched the tie-down, it would short. But the same holds true for every other battery tray on the market, including the factory one. The point is, keep your tie-down tight. In light of this concern however, I will be brainstorming an option for greater insurance. It may be as simple as some tubing around the tie-down or maybe just some locking nuts on the tie-down.

Another option for battery trays. We can mount your relay wherever you want. Just ask!
