Lithium Iron Phosphate, or LiFePO4, batteries are one of the most durable and reliable energy sources on the market and a drastic improvement over lead-acid in safety, weight, capacity and shelf life.



Lithium Iron Phosphate is the safest lithium on the market. It will not explode or catch on fire. It is absent of potentially volatile chemicals that are found in other lithium cells.

Long Lifespan

Lithium Iron Phosphate batteries have up to 6,000+ life cycles without significantly decreasing performance. That means they last for years and years. By comparison, the average lifetime of lead-acid batteries is just two years.

High Efficiency

Lithium Iron Phosphate has 100% of its capacity available for use. It can be quickly charged, discharged and recharged again and again, reducing downtime while increasing efficiency. This makes it a great fit for a variety of applications.

No Active Maintenance

It does not require active maintenance to extend its service life. The batteries show no memory effects and can be stored for long periods of time because of the extremely low self-discharge rate (<3% per month).

Flexible Use

Because they emit no fumes or require little air flow, you can use them inside or outside. They can be stacked on top of each other or can be used in any position.

Peaks and Valleys Energy Use

Using Lithium Iron Phosphate for energy storage, you can optimize usages and help solve the peaks and valleys that occurs during high and low energy demand usages. This also can help to stabilize the grid from intense demand cycles by allowing you to use the stored energy when you need it.

Renewable Power

For the first time, green energy can not only be generated but can be effectively stored and used as needed. You can harness the power of the sun and use it over and over again.

Lightweight and Portable

Lithium Iron Phosphate batteries are relatively small and light weight. Compared to lead-acid batteries, lithium provides great energy density at about half the mass and weight.

Energy Independence

Energy storage allows you to be independent of the grid so you can have energy where and when you want it. So, no worries about black outs, brown outs, or when the grid goes down.

The Lion Safari ME and XP are made from Lithium Iron Phosphate and is the safest solar generator and expansion pack on the market. Because they do not emit any toxic fumes or gases, you can use them inside your home, tent, RV or any other confined area. Lithium Iron Phosphate is the highest grade, safest battery composition available and has no potentially volatile chemistry. The ME and XP go through extensive testing from initial design, through production, and before it ever leaves Lion Energy.

If you want to know more about how safe Lithium Iron Phosphate is (Safari ME and XP) click below.


What are the Safari ME and XP?

The Safari ME and XP are the latest in Lithium battery technology for portable power needs. They replace traditional noisy gas generators with the safest Lithium batteries on the market today. They are light weight for the amount of power and stored energy they have. Think of it as a safe, silent, renewable generator and extra energy storage without the need for gas, pollution or all that weight.

What does the Safari ME power?

You can use it to power a wide variety of devices like cell phones, laptops, tablets refrigerators, freezers, TVs, lights, hot plates or grills, power tools, and the list goes on. Virtually any device you can plug into a standard wall outlet, the Safari ME can power it. And with the optional ME-XP expansion battery, you can power all that for longer.

How can you figure out how long the Safari ME and XP will power specific devices?

The ME has a continuous 2,000W of power output (watts of power output) and over 900Wh (922 watt hours) of stored energy. The ME-XP adds nearly another 2,050Wh more when connected to the ME. That means you can power devices that require up to 2000W of power for various periods of time. To calculate how long the ME can power a device, use this formula: Wh / W = Estimated Run Time. For example, if the device requires 50W of power and the ME has 922Wh then the device can be powered for approximately 18.5 hours (922 / 50 = 18.44) If you use that same device but now with the XP connected to the ME, you'll have 2,970Wh to use in this formula (2,970 / 50 = 59.4).

How long can the Safari ME and XP hold a charge?

They will maintain their charge for up to a year (ME) or two (ME-XP) without having to charge them. This is known as shelf life or storage life. They will lose about 2-3% charge on average each month (more in the first month and less in subsequent months), assuming the unit is fully charge to begin with. However, we recommend using the ME and XP frequently, in the house, outside, on adventures and for emergencies.

Can the Safari ME and XP power an A/C unit?

The Safari ME outputs 2,000W and can power some AC units depending upon the brand and the watts each AC unit requires. Like with most devices, the power consumption varies from brand to brand and model to model. So you'll need to determine if the AC unit is less than 2,000W.Check out our videos tab for a detailed review on the ME. Remember, if you connect the XP to the ME then you get an extra 2,048Wh of stored energy to power things longer.

How can I connect the Safari ME and XP to my house?

You would need a home integration kit, which is generally found at home improvement/electrical supply/hardware stores.

Can the Safari ME and XP be used to store solar power or solar energy?

The Safari ME and XP are a great energy storage combo unit for solar power from solar panels. Together they can store 2,970Wh (watt hrs) of energy.

Why should I buy the Safari ME and XP?

The Safari ME and XP are made from the highest quality and longest lasting battery technology – Lithium Iron Phosphate. The Safari ME and XP are safe, silent and renewable, unlike gas-powered generators. The ME gives your power anywhere, anytime. The ME-XP gives you more time to power those devices.

Will the Safari ME and XP work with power tools?

Yes, most power tools will work just fine with the ME and XP. Some require more energy at startup (a surge) and may need to have a "soft start" component added to the ME that can be found at home improvement, electric supply, or hardware stores.

Lion Energy expansion Pack XP recert

Being a true LiPo4 battery and twice the capacity of the primary ME unit, this is a no brainer if you're looking for a Solar Generator. When asked what my recommendations would be for buying a solar generator, I always say : Make sure you're buying a LiPo4 battery (NOT an NMC) and that the primary unit is expandable. The primary unit should be 2000wats (This unit is 1000w), it should be rechargeable by several methods and be easily portable. Although this unit is only 1Kw, it allows for expansion batteries that are easily plugged into the ME, and are they are relatively affordable. Only downside I can see (for MY needs) is that this uses a 24volt solar system. I have a bunch of 12volt panels, but I suppose I could just put two in series? The other units I have use MP4 connectors, but Lion uses a 30a Anderson connector, so I had to buy an adapter from MP4 to Anderson, aout 12 bucks. The capacity of these units are great, they are easily transportable and should last a very l o n g time. I just wish that the XP could be AC charged independently, but that entail the addition of a charge controller which would me a higher cost, so,...overall a very nicely constructed unit that I expect years of service from. I call Lion prior to purchase. I asked whether if you depleted the ME, you could just plug in the XP and was told yes. Perfect for my needs.

Beyond satisfied

When we returned home with the ME Expansion pack recertified, we began testing it's ability. We took it to deer camp. We have an electric fridge in the garage area of the camper. The expansion pack ran the fridge for 3 days. It's was not depleted when I added the solar panels. I would also like to add that we damaged the case when a strap broke on the tie down. Our UTV bounced on the expansion pack but it still operates perfectly. Lion Energy did a free total replacement. Thank you Lion Energy!
