Genesis Offroad - Quick Introduction & Overview of our Dual Battery Kits

[genesisoffroad]

Hey Roofus,

I'll try to give you the condensed version here, but always feel free to call us anytime - 901-214-5337.

First, batteries are typically rated in Amp Hours. The Full Throttle Group 25 that we sell for the Bronco has 64 amp hours of capacity. To convert that to watts, just multiply amps by volts, so 64 x 12 = 768 watts (loosely).

Next, I'm not familiar with the Bluetti, or the Pecron charger, so I'll speak generically here. What you're describing sounds like the charger turns off if the input voltage drops below 13v, is that right? If so, I'd try to change that threshold down lower if possible. The reason is that most modern vehicles have a smart alternator that sense when your main battery is fully charged, and the alternator can free spool in order to try to save you a drop of gas, which means it's not putting out as high of a charge voltage level, so you see it drop down below 13v and your charger turns off. It's normal for the alternator output to drop down to 12.5 or maybe even slightly lower. As long as the engine is running though, you want your charger running as well.

To your direct questions, about running a fridge overnight, generically, yes, the aux battery in our kit should be able to run your fridge for an extended period of time. How long depends on several factors. Is the battery completely full when the engine turns off, is the fridge completely cooled down before running from the battery only, the ambient air temp, how often you open the door, how often you remove cold stuff and replace it with warm stuff, what else is running from the battery power, etc.

For charging the Bluetti, again I can't speak about that product, but it's typically less efficient to use a battery to power a charger which charges another battery which then runs your fridge, than to simply run the fridge from the first battery. You're going to have some loss of efficiency just from powering the charger in the Bluetti.

Best case scenario - get our dual battery system with high quality AGM batteries like Full Throttle or Odyssey, consider getting our G Screen Monitoring System to keep an eye on the battery levels, and get our new Bronco Power Box which will let you run the fridge from the aux battery without draining your cranking battery. Then use your Bluetti as a backup device if you need extra run time without needing to crank the engine.

I hope that helps! Let me know if you need more info!

Thank you very much, Shane! That's helpful. I'll probably still give y'all a call to make sure I'm understanding everything correctly.

Here's a link to the Pecron charger for reference: https://www.pecron.com/products/pecron-500w-car-charger-dc1242-500-for-car-rv-van
Ecoflow also makes this 800w version: https://us.ecoflow.com/products/800w-alternator-charger and Bluetti's just released there's here: https://www.bluettipower.com/products/bluetti-charger-1

Hello Shane, would you be able to provide an ETA on when the Power Box for the 4 door Bronco would be available. I am very seriously considering purchasing the dual battery system and would like the Power Box as well. Thanks!

Honestly I don't have an ETA for you at this moment. However, here's one possible idea for the 4 door guys, if you want to take advantage of our Power Box. You could get the current 2 door version, bolt it in place using one hardtop bolt, and use some 3M sticky tape under the lip on the other side since that other bolt hole won't line up in the 4 door. Just a suggestion!

We'll try to get a new design specifically for the 4 door soon.

Thanks!

So, i just recently installed this with the two group 25 Odyssey, on my 1st short trip (less than 15 miles) it popped a "check charging system" issue. Truck has 1050 miles on it and nothing hooked up to the bus bars yet. I did install with the engine on sensor cable and the button is switched to auto.

Do I need to do anything to make sure I don't have a problem?

Thanks in advance!

Driven twice since I posted, hasn't popped an additional alert, possibly this was due to initial install and needed to cycle?

Any info would be greatly appreciated.

The most common solution to this type of symptom is to make sure all 4 battery post clamps are tight. Grab each cable and give it a tug. If you can wiggle the clamp on the battery post even a little bit, it can lead to all sorts of bizarre gremlins, including those that indicate your charging system (alternator) not able to charge the battery.

As long as you are getting power into the batteries from the alternator, and power out to your factory fuse box, the rest of the vehicle doesn't know anything about our system. It's just giving you extra battery capacity when they are connected, and protecting the cranking battery from your accessories when the engine is off.

Found the potential culprits, it was inside the unit. I was able to tighten each of the main posts inside significantly. This was the only "play" in the system.

I recorded a video of how much i was able to tighten on the positive cable, but the negative was just about the same.

Hopefully this fixes up the issue and I can move on to some more fun stuff for my build.

Might want to check QC on the final assembly and make sure those get tightened down before shipment.

Thank you very much for bringing this to my attention. I'll certainly make sure this doesn't happen again. Happy New Year! -Shane

Currently don't need this but if I do want a system definitely going with this as i will never be going for extended amount of time without power. Will go with this because Shane's effort in answering all questions asked!!

I may have missed it in my skimming through, But I know yall suggest odyssey group 25 to prevent trimming something, can you show exactly what would have to be trimmed to use other batteries?

Thank you! We have plenty of kits in stock when you're ready!

Watch this clip starting at the 4:20 mark. I'm pointing at the radiator support bracket at the corner of the battery. If you want to notch this bracket to allow the battery to move toward the fender a little more, then you could fit other batteries in there.
