Affordable Approachable Lithium

We all have read about lithium batteries and how it's the newest game in town. Incredible packaging, weight, charge and discharge qualities. All wondrous things. At a price with significant install complexities.

What if I told you a large capacity battery system with lithium qualities could be affordable and approachable? With some unique benefits.

The device is not new. The integration strategy and approach is what's new here.

Enter Goal Zero Yeti portable battery stations. I used the Yeti 1000 model which is a 98Ah portable lithium battery, with built in charger and high power inverter.

I've always dismissed the idea of replacing solid existing installed capacity with a different flavor of the same capacity. Or thousands more just to match or actually increase the installed capacity I have. But I've always wanted for real high power discharge capabilities to power a residential hair dryer, microwave, etc., something that lithium are great at.

Strategy is a dual battery bank system where the lead acid 12V "house" battery takes care of the house loads. Augmenting with a lithium battery system to handle the 120V "accessory" loads. In this way, I'm not paying for premium batteries to supplant basic uses. That premium accessory capacity is installed above and beyond the house capacity I already have. 215Ah in my 6V lead acid batts. Adding another 98Ah Goal Zero Lithium.

300Ah capacity. For $1000.

Like I said, the integration is what's unique here. This also works great on older trailers to add a 120V inverter inclusive in that same $1000.

I've installed a 120V transfer switch ($75) behind my Airstream power center. This allows the Goal Zero Yeti via its own onboard inverter to power all 120V loads and outlets on the trailer as if it were plugged into power hookups. This allows me to use it for discretionary accessory uses like microwave, hair dryer, TV, and whatever else with superior lithium supported power. With a push of a single button to turn on that Yeti 120V inverter.

So what about charging?

That's the other half of the unique integration. It couldn't be simpler. The Goal Zero Yeti's have built in onboard chargers. Just add a $39 "12V Yeti Car Charger" that charges at 5 or 10 amps. Plug it into any cigarette lighter port. It has a built in voltage relay that switches at 12.8V such that it will only charge when it detects charging voltage. Such that it doesn't charge from and draw down the house batteries.

That means any charging source including the converter charger, solar, generator, car umbilical, can provide charging power to the lithium bank by virtue of it being plugged into the 12V bus.

I have 400W of solar on my trailer. My two battery banks are primarily charged evenly and nicely from that source alone.

Bonus, I can easily unplug the Goal Zero to use in a portable fashion away from my trailer. It also works great as a standalone backup in case anything in the trailer electrical system were to fail.

Very cool. Saw also your inverter thread. This is something I might adopt in a couple of years.

Nothing against Battle Born batts, but this is wholly a different strategy and value proposition. Battle Borns are a different LifePO4 lithium chemistry better suited for permanent install. Roughly $1k for 100Ah. Whereas the GoalZero is an all inclusive package with greater power density, built in high power inverter, charger, likewise $1k for 100Ah. Value, portability, capability, and ease of use is the trade.

Fundamentally, this install is akin to having dual battery banks. A strategy used in bigger RVs and boats. Separation of concerns. Failsafe's. Support of multiple draws to different banks such that the load is not all on a single battery at higher c-rates.

The challenge of dual banks traditionally has been the need to duplicate battery management, chargers, distribution etc. This is where the Goal Zero type batteries help as it has everything built in.

I have a 2000W inverter existing in my trailer. I literally can throw this out now with the better inverter on the Goal Zero (1500W/3000W surge for 30 seconds). That's 2000W inverter is a $400 component that is made superfluous by the Goal Zero. Looked at another way, if one wanted to upgrade their trailer that does not have lithium and does not have an inverter, that's a huge discount on the two components.

GZ also has 132Ah (Yeti 1400) and 280Ah (Yeti 3000) solutions. Imagine a Yeti 3000 installed on top of solid house batteries. That's almost 500Ah for $3k. Something that traditionally has required a significant time and money outlay on the order or $10k++

More interesting is the GZ is expandable. I can add cheap AGM batteries chained to the Goal Zero Yeti's, yet keep the lithium performance properties of that battery bank.

It has a nice readout. You can see the roof installed solar charging it on low at 60W. I tested it pairing a microwave and heater to 2200W. I might even try the A/C on it for kicks. Here's just the coffee maker.

This sounds like a significant addition to my power system. I have not felt the GoalZero Yeti implementations so far were cost-effective improvements, but this seems like a really good idea. I'm going to seriously consider this as a part of my ongoing power system reconfiguration necessitated by replacing my jackknife sofa with a recliner loveseat.

Yup. I did this in my Interstate 16 months ago. We have been full time in it for over a year now and the Goal Zero 3000 has been a great addition. Our separate fridge and freezer combined use about 8A, (100W) which deplete my 220Ah AGM batteries overnight (that floor being 50%, or 110Ah). I've decided not to use a charger via cigarette lighter and I use a bank of four GZ chargers which charge in up to 10 hours if it is very depleted.

Initial writeup here: http://www.airforums.com/forums/f240...-a-177828.html

Also, new discoveries on how best to use it, just documented here (more details to come). http://www.airforums.com/forums/f240...er-196410.html

Glad it works for you. Looks like it would take up a lot of room. You have a nice place to put it. My only option would be the closet. Then how do you wire it so it remains portable. I see other comments that it takes forever to recharge and the inverter is 1500 watts not 2000.



You add the transfer switch and and extra $ for their charger plus wiring might as well go with a regular lithium such as Battle Born

Hi NoResults. The pics don't show scale well, but it's a fairly compact unit (10.1"L x 15.3"W x 9.3"H). Small enough that I could locate it in any one of my lower storage spaces on my 27FB trailer easily.

I have two wires plugging into the unit: 120V plug, and 6mm barrel charging adapter. Barely more difficult to unplug than my electric coffee maker. I can unplug the GZ and my trailer continues to have full electrical support from the house batteries, including 120V as I have a separate 2000W inverter (2000 was in reference to this separate inverter).

Charging speed is a matter of capacity and preference. I have mine charged and tendered by solar where speed is not really a concern. At 10amps (120W), it'll charge from fully depleted in about 1 sunny day. Goal Zero makes a number of different chargers and options, including 50amp 12V chargers, 25amp 120V fast charger. I don't need any of those for the way I'm using mine.

I got my Goal Zero on sale for $800. Add $75 for transfer switch. Plus some misc wires I had at home and did the install setup myself. The transfer switch is wholly optional, but was a cheap and easy addition for me.

These prices are in a completely different ball park than your suggested Battle Born. A single $1k investment is 1 bare battery. I can't do anything useful with that. If I install it in place of my house batteries, I've downgraded to only 100Ah capacity. One has to invest in a minimum of 2x Battle Borns at $2k to begin to play.

Seems like a good way to to add an inverter and a 100 Ah lithium battery without any technical know how.
Is the inverter 1000 watts? When I had my 1000 watt inverter I was not able to operate even the smallest microwave. This is why I installed a 2000 watt inverter.

Dan, the inverter on the Goal Zero Yeti 1000, 1400, and 3000 are all 1500W inverters. With surge capability for 30 seconds to 3000W, which is beyond what most residential 15amp circuit breakers will allow.

I have tried, and it will definitely do what it says, without power sag. That is the beauty of lithium batteries, to be able to support 1C power draws continuously.

1500W continuous is enough to power anything you could plug into standard 120V plug at home. Generally, devices don't draw more than 1500W continuously at least, as it has to follow the 80% rule for a circuit. 120V @ 15amp is 1800W max, or 80% of that is 1500W continuous. The Goal Zero should handle anything you want to plug in.

Yes, I posted a months or so ago to one of the other Yeti threads, that I had used a GZ Yeti 3000 to emulate shore power with some success. No the AC will not run, but most everything else did. The Microwave was a bit touchy, and I believe on less that full power you can skirt the 30 second surge limit. I kept my Yeti on the backseat of my Silverado, and ran the shore power connection through the sliding rear window. I had two 180W Grape Solar panels on mounted on the tonneau cover and recharged it with Solar during the day. I also had an ef2400is Yamaha generator that I used to charge via 4 standard wall chargers with a branch connector to the Anderson Power Pole input (I have plenty of inputs on my 3000 with the MPPT module dedicated to solar). I was inputting over 500W at some point.

I was camped at a festival where generator usage was limited to off hours, as the noise was not allowed while the stage was occupied. Really like NOT having to run the genny most of the time. I also used the genny to make sure the house batteries had a full charge via a BatteryMinder charger.

I now have two Yeti 3000's AND a Yeti 1000, all of which I bought during the recent Costco and REI sales. And I've added two 100W Grape Solar Panels to the roof of my truck for a total of 560W! That gives me the option to charge two yeti's at the same time (any combination of two of the four each), or use branch connectors to combine all four to charge a single yeti.

As the original poster said, it is flexible and multipurpose. No mods to my trailer at all, and all at a cost that was less than Airstream OEM Solar. And I can use the Yeti's as backup power for my house during outages here in Florida. I have an 11.5 KW roof mounted Solar System on my house, but it is inaccessible during outages, but my Portable Grape System is. And with the surplus I am generating with my home system, my Yeti's are always charged and ready to go. BTW, Enphase, the maker of y rooftop microinverters, is now marketing a system that makes Rooftop solar accessible during outages, so I am looking into that.

Thumbs up

. . . similarly . . . the Goal Zero units are also useful as mobile power stations during hurricane season . . . and can be loaned to family and friends who need to keep a fridge etc. going . . .

Along with small propane-fired generators which can run off a 20-lb. BBQ tank, a continuous source of power can get folks through the tough times.
