What is a LiFePO4 - Lithium Iron Phosphate Battery?

Traditional lithium-ion batteries, which are the newer, most widely used option, have gained a reputation in recent years for catching on fire. This is why lithium batteries typically are not used to create large battery banks, but then lithium iron phosphate was discovered.

Also referred to as LiFePO4, these batteries are safer and more reliable for high-power applications, such as charging stations. Although they aren’t new, they are now becoming more noticed - and finally being recognized as a greater alternative to lithium-ion. With ROCKSOLAR’s eye always on the best technology that gives you the most for your money, it’s natural that we carry various types of LiFePO4 batteries for you to choose from.

Why LiFePO4?


LiFePO4 is extremely efficient when it comes to saving space and being portable. These batteries are one-third of the weight of most lead-acid batteries and half the weight of popular batteries which are composed of manganese oxide. When using LiFePO4 while traveling, the lighter weight means less gas usage and more maneuverability, for a car, boat, or RV.


LiFePO4 batteries do not contaminate the earth like the batteries you’re used to - they are non-toxic and contain no rare earth metals, making them the most environmentally friendly choiceyou can make. Most batteries, like lead-acid and nickel oxide lithium batteries, containchemicals that are not biodegradable and can leak toxic substances on whichever landfill they end up in.LiFePO4 batteries are also amazing for the planet because they are rechargeable - meaningthey won’t even end up in a landfill in the first place. They are recyclable and extremely long-lasting - so when the time comes (far from now) to dispose of them, you can rest assuredknowing they will not harm wherever they land.


As mentioned before, a lot of people are making the switch to LiFePO4 batteries as traditionallithium-ion batteries have been known to cause fires and be extremely harmful when leftunattended or to charge devices on a larger scale. LiFePO4 batteries have great thermal andchemical stability, making their cells incombustible which means that they won’t start a fire andthey can also withstand hard conditions, like blizzards, deserts, or rocky terrain.

Quick Charging

When you purchase a battery you want it to last as long as possible. While LiFePO4 batteries are wonderfully rechargeable, they also have a long lifespan and recharge quickly because of their lightweight. The service life is around 10 years, and the runtime when using the batteries is longer than any lead-acid or other lithium formulated battery you can buy. If you want a battery that will both charge quickly and stand the test of time, LiFePO4 is the perfect choice.
