There's a lot of things to love about the Safari UT 250 from the light weight of just over 5 lbs. and zero maintenance to it being able to be recharged with renewable sources like the sun.

Weighs Less
At only 5.2 lbs, it super light weight.

Made from Lithium Iron Phosphate, it's the safest lithium battery on the market. You can use it indoors or outdoors.

Lasts Longer
Long lasting life cycles at 2,500+ using full depth of discharge (DOD). It can hold a charge for up to 1 year.

Renewable Solar Batteries
Use the power of the sun to fully recharge the UT 250 in as little as 2.5 hrs.

2X the Energy
You can use all the stored energy (20Ah) of the UT 250 instead of only half, like lead acid batteries do.

Expandable for More Power
If 20A continuously and a 35A peak, isn't quite enough, connect two in parallel or in series for more power and capacity.

Zero Maintenance
No fluids. No trickle charging. No mess. The Safari UT 250 just works – day in and day out.

7 Year Warranty
Using Lithium Iron Phosphate technology it can be drained and recharged over 2,500 times – much longer than Lead Acid batteries. That is why it's backed by a 7 year warranty.

Environmentally Friendly
Produces zero emissions or carbon footprint during use, no greenhouse gases, and does not damage the environment. It's good for you and the planet.


Our UT battery series comes with our own proprietary BMS that will protect your battery from harm. It's like having its own bodyguard.

The Safari UT series all have an internal Battery Management System (BMS) that acts as a safety net to shut down the battery if it goes outside of set parameters. This prevents the battery from overcharging or discharging as well as operating outside of specified temperature range.



  • Camping / RV
  • Marine / Water Use

This small but powerful battery has 20Ah of capacity which can provide a full day of power for electronics like a fish finder, ice auger, gazebo lights, or powering your wheelchair or mobility scooter. The UT 250 is a great, smaller option.

We have created a step-by-step walk-through on how to use the the UT battery series for either:

In addition to powering all your toys, you can also use your Lithium Iron Phosphate batteries to be prepared for any emergency.

The Lion Energy DIY Solar Kit lets you harness the power of the sun, store the energy in your UT 250 battery, and convert it to power for your devices, tools, lights, and many other power needs. Use the DIY Kit for your shed, cabin, gazebo, campsite, or outdoor adventure.

Frequently Asked Questions

What is the Safari UT 250?

The Safari UT 250 is the latest in Lithium battery technology. It replaces traditional deep-cycle lead acid batteries with the safest Lithium Iron Phosphate. It is a "plug and plays" battery. Simply remove the deep-cycle lead acid battery and replace it with this superior-performing battery.

What does the Safari UT 250 power?

The Safari UT 250 is an amazing Lithium Iron Phosphate battery that can be used for auxiliary power in Boats, Cabins, Sheds, Gazebos, and where you need a reliable source of stored energy. It replaces lead acid batteries and provides twice the energy because all of its energy (amp hours) can be used instead of only ~50% like lead acid batteries provide. How about using it to store energy in a cabin so you can power lights and more? Yes, you can use it for that too. It can be used 100% and then recharge over 2,500 times and still have 80% of its capacity left. (Note: The Safari UT 250 is not a battery to use for starting vehicles.

How long does it last?

The life of the Safari UT 250 Lithium battery is approximately 14X that of deep cycle lead acid batteries in its class. And it comes with a 7-year warranty.

How long can the Safari UT 250 hold a charge?

The Safari UT 250 will maintain its charge for up to 1 year without having to charge it. This is known as shelf life or storage life. However, we recommend using it more frequently.

Can it store solar power?

The Safari UT 250 is a great energy storage unit for solar power from panels on homes, cabins, businesses, and RVs, just in smaller amounts than the Safari UT 700 or 1300.

Do I have to maintain it?

The Safari UT 250 is virtually maintenance-free, meaning you don't have to use it or even trickle charge it every 3-4 months or deal with water or acid since it doesn't have any. It can hold its charge for up to 1 year and can be recharged and used time and time again.

Is it good in bad weather?

The Safari UT 250 performs better than lead acid batteries in most weather conditions. It can charge between temps of 32° to 113° F and can discharge between -4° to 131° F at 100%.

How big is it?

The Safari UT 250 weighs in at just 5.2 pounds. The dimensions are 7.1" x 3.0" x 6.6" (L x W x H)

What's the rated capacity?

The Safari UT 250 is commonly referred to as a 12V, 20Ah (how much energy is stored), 256Wh. Technically, it is a nominal 12.8V lithium iron phosphate battery.

Can you use it in series or parallel?

Yes. The Safari UT 250 can increase the voltage from 12V up to 48V total by connecting them in series (4 batteries connected together via + to - posts). You can increase the amps (A) and Amp Hours (Ah) up to 140A and 60+ Ah in parallel (+ to + and - to -). If you really want to increase your power and capacity, we recommend upgrading to the Safari UT 700 or 1300.

Battery Charging Parameters

We recommend setting all voltage to a max of 14.6 per Safari UT in series or at least close to it. End amps or tail amps need to be set as low as possible and the inverter's low voltage needs to be set to 11.5V. Victron inverters charger and charge controllers should be set to 13.9V for a 12V inverter and 27.8V for 24V inverters.

What is a BMS?

The Safari UT already has an internal Battery Management System (BMS) that acts as a safety net to shut down the battery if it is out of specific parameters. This prevents the battery from overcharging or discharging as well as operating outside of the temperature range.

Can I use my standard charger?

Yes! You could use a standard battery charger and it will charge the Safari UT battery. However, since most chargers are designed for a lead acid battery, they are made to go up to a certain voltage. On a lead acid battery, their "full" is about between 12.8V and 13.8V. The Safari UT 250 can accept a charge of up to 14.8V. Most chargers will get batteries up to 13.8V. For best performance, we recommend a lithium charger.

Can I use a heating element to keep my lithium batteries above freezing?

If you want to use some type of heating element to keep the battery above freezing, do an online search or check out sites like You can keep the battery inside so it's not exposed to extreme temperatures.
