How You Can Add Batteries To Increase The Capacity Of Your Goal Zero Yeti Lithium<\/h2>\n

The Goal Zero Yeti power stations come in lots of different sizes and configurations. Some of them are lead-acid batteries and other lithium. In an earlier post<\/a>, I wrote about how you can double, even triple, the battery capacity of a Yeti 400 and Yeti 1250. Today I am going to help you increase the battery capacity of the Yeti Lithium models.<\/p>\n

You can increase the battery capacity of the Yeti Lithium power stations that have an expansion module slot. Like the Yeti 1000<\/a>, Yeti 1400<\/a>, and No products found.<\/span>.<\/p>\n

It’s also possible to connect a Yeti Tank Expansion battery to the Yeti 1250, by using the 1250 Ring Terminal Connector Cable<\/a>. To do this, you’ll remove the lid of the Tank battery to install the ring terminal cable.<\/p>\n

Since the MPPT charge controller uses the same expansion module slot, this means you can’t use both at the same time. That’s a bummer, but I believe in future Yeti Lithium power stations, the MPPT charge controller will be built-in, so you can use both.<\/p>\n

Now, let’s take a look at what you need to expand the battery capacity, and answer the most frequently asked questions.<\/p>\n\n

How It’s Done<\/h2>\n

To increase the battery capacity of a Yeti Lithium power station, you can connect Yeti Tank Expansion batteries. But in order to do so, you need a Yeti Link. Let’s take a closer look at each of them and how they work.<\/p>\n

The Yeti Link Expansion Module<\/h3>\n

To connect a Yeti Tank battery to the Yeti power station, you’re going to need the Yeti Link Expansion Module<\/a>.<\/p>\n

The Link Expansion Module is installed where the MPPT charge controller is already installed on the Yeti 3000, or in the empty expansion module slot on the Yeti 1000 and 1400. It’s very easy to install, you just have to remove a couple of plastic screws and connect two cables.<\/p>\n

On the front of the Yeti Link, there is an 8mm input capable of inputting 150W to the Tank batteries or the Yeti. There is also a battery indicator with 4 LED lights, that show the state of charge of the Tank batteries with 25% increments.<\/p>\n

On the back of the Yeti Link, there is an EC8 port which is where the Yeti Tank batteries are connected.<\/p>\n

The EC8 port on the back can also be used to recharge the Yeti from an alternator in a vehicle. To do that, you’ll also need a Male EC8 to Ring Terminal Cable and an EC8 extension cable.<\/p>\n

The Yeti Tank Expansion Battery<\/h3>\n

One Yeti Tank expansion battery holds a 12V battery rated at 100A, which means that it holds 1200 watt-hours. The Yeti 1000 has 1045 watt-hours of battery capacity, so it will more than double the capacity with one expansion battery.<\/p>\n

The way the Tank battery works together with the Link module is that it will charge the Yeti battery.<\/p>\n

The only way to recharge the Yeti Tank batteries when connected to the Yeti Link is through the 8mm input on the Yeti Link module. Charging the Yeti via its PWM charge controller with either a wall\/car charger or solar panels will not charge the Tank batteries.<\/p>\n

When the Tank battery is charged and the Yeti Lithium battery isn’t, you’ll see input on the Yeti screen of between 400-700 watts. This is the Tank battery charging the Yeti battery.<\/p>\n

It’s also possible to buy a third-party PWM\/MPPT charge controller and connect it directly to the Tank batteries.<\/p>\n

The Yeti tank expansion battery is not a lithium battery but a deep-cycle AGM battery. You can add as many Tank batteries as you want since each battery has two in\/out cables.<\/p>\n

How To Connect The Battery To The Link Expansion Module<\/h3>\n

Connecting the battery to your Yeti is as easy as connecting a cable.<\/p>\n

The Yeti Tank battery has two EC8 connectors coming out of it. One of them can be used to connect an additional Tank battery, and the other will be plugged into the back of the Yeti Link expansion module.<\/p>\n

Goal Zero has made a video about the Yeti Link expansion kits that you can view down below. I recommend watching it to easily understand how it’s set up and works.<\/p>\n
