More Power? You Got It.

Unlike other batteries, the UT 1300 outputs 150A continuously and a 900A peak. More output means more power for your RV, Motorhome, Boat, Shed, Gazebo and Dump Trailer.

Lithium Battery Winter Usage Tips

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

Note, ALL types of batteries need to be above freezing in order to charge them. As a result, it is best to use the batteries in a climate controlled location (not on the tongue of a trailer or using a lead acid battery compartment that has to be ventilated, thus allowing freezing air to circulate around the battery).

The Safari UT and other lithium batteries can be placed in an insulated space, inside the RV or other climate controlled areas. Some users have suggested using a Battery Heating Pad that you can find online. We recommend using the battery in a climate controlled location.

Questions about Safari UT 1300

The Safari UT 1300 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 play” simply remove the deep cycle lead acid battery from your RV or boat and replace it with this superior performing battery.
The Safari UT 1300 is an amazing Lithium Iron Phosphate battery that can be used for auxiliary power in RVs, Trailers, Motorhomes, Boats, Cabins, Sheds, Gazebos, Dump Trailers 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. For example, use it in an RV to power slide outs, lights, microwave, TV, AC, etc and get twice the camping time than a lead acid battery. Want to use it to power a trolling motor? No problem, and you’ll get not only a longer use time, but it also weighs less than half a lead acid battery and that’s a big deal in a boat. How about using it to store energy at a cabin so you can power lights, TVs and more? Yes, you can use it for that too. It can be used 100% and then recharged over 3500 times and still have 80% of its capacity left. (Note: The Safari UT 1300 is not a battery to use for starting vehicles.)
The life of this Lithium battery is 14 times that of deep cycle lead acid batteries — this is literally a lifetime battery — thus a Life Time Warranty.
The Safari UT 1300 is a great energy storage unit for solar power from panels on homes, cabins, businesses and RVs.
The Safari UT 1300 is virtually maintenance free, meaning you don’t have to use it or even trickle charge it every 3-4 months, deal with fluids since it doesn’t have any, or remove it from your vehicle and store it for the next season. It can hold its charge for up to 2 years and can be recharged after that time too.
It will maintain a charge for up to 2 years without having to charge it. This is known as shelf life or storage life. We recommend using it more frequently than every 2 years, though.
The Safari UT 1300 performs better than lead acid batteries in most weather conditions. It can charge between temps of 32° to 113° and can discharge between -4° to 131° at 100% rate. Outside these ranges it can discharge at a lower rate.
It weighs in at just 23 pounds and is the same 24 Group Size as other batteries. The dimensions are 10.2” L x 6.6” W x 8.8”
It is commonly referred to as a 12.8V, 105Ah (how much energy is stored in it), 1344Wh (12.8V x 105Ah). Technically, it is called Nominal Voltage at 12.8V and 105Ah. It can do 900A for a millisecond (a spike) then approximately 250A for one minute and 150A continuous (how much power it puts out) capacity.
Yes. You can increase the voltage from 12V on a UT 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 1500A and 1000Ah by connecting them in parallel (+ to + and - to -).
We recommend setting all voltages to a max of 14.6 per UT in series or at least close to it.
End amps or tail amps need to be set as low as possible and inverter low voltage needs to be set to 11.5V.
Victron inverters charger and charge controllers should be set to 13.9 volts for a 12 volt inverter and 27.8 for 24 volt inverters.
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 parameters. This prevents the battery from overcharging or discharging as well as operating outside of the temperature range.
Yes! You could use a standard battery charger and it will charge the batteries. 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 13.8V. The UT 1300 can accept a charge up to 14.6V. Most chargers would get the batteries to 13.8V. For best performance, we recommend a lithium charger.
Yes, the Safari UT will take too much current so you must limit it with the wire you use to charge it. For example, if you need 10-12 feet of wire, a 10-12 gauge wire will work to limit the current. Double check the actual current with a current meter and size the fuses appropriately. You may need to add fuses and other protective equipment to protect the system. To prevent possible damage to your alternator we recommend using the Redarc (Model #BCDC1225D), which is a DC-DC charger. It will safely charge your batteries while you are driving.
