Our FAQ lounge zone
01
What is LiFePO4 battery?
LiFePO4 batteries are a type of rechargeable battery that have a number of advantages over other types of batteries. They are environmentally friendly because they do not contain lead or acid. They are also exceptionally durable and can last for up to 10,000 charge cycles. This makes them an excellent choice for use in electric vehicles and other applications where durability and longevity are important.
02
Why are LiFePO4 batteries better for powersports?
There are many reasons that LiFePO4 batteries are better for powersports than lead acid batteries. For one, they are much lighter weight, which makes them easier to transport and install. They also have a much longer life span (cycle life), meaning they will not need to be replaced as often. Additionally, LiFePO4 batteries are less susceptible to damage from vibration, making them a better choice for vehicles that are used off-road or in other rugged conditions. Lithium Unlimited Co’s batteries are additionally padded inside for further shock and vibration resistance.
03
How do they compare to other types of batteries?
LiFePO4 batteries have a high energy density, meaning they can store a lot of energy in a small package. This makes them a good choice for extreme off the grid scenarios where you might want to charge a phone or run a spotlight as well as start your vehicle. Just ensure you don’t go too low in the charge. They also have a longer lifespan, meaning they can be used for multiple charges and more seasons.
04
Is it true that lithium doesn’t like the cold?
Lithium can be sensitive to temperature extremes. However, our cells are specifically designed to operate over a huge temperature range to overcome that. Our low-temperature batteries can operate at -35 degrees F when operated per the manual and can operate as high as 160 degrees F without damage or any issues.
05
I have heard that Lithium is dangerous?
Other types of lithium can be dangerous if punctured. LiFePO4 is a much safer technology and will not catch fire under the vast majority of circumstances. Our batteries are additionally protected by a specially designed Battery Management System, BMS for short, which greatly increases safety & protection.
