What is Lithium Iron Phosphate?

Lithium iron phosphate is a chemical compound LiFePO₄ or “LFP” for short. LFP offers good electrochemical performance, low resistance and is one of the safest and most stable cathode materials available for lithium-ion batteries.

Why BLUETTI Chooses LiFePO₄

Safety &

LiFePO₄ batteries are best known for their strong safety profile, resulting from highly stable chemistry, which is something lead-acid, and most other battery types don’t have at the level LiFePO₄ does. In the experimental environment such as acupuncture and high temperature, when the traditional NCA/NCM battery deflagrates and catches fire, the lithium iron phosphate battery in the same environment only emits smoke slightly without any visible flame.

Unrivalled Longevity

Battery Life Cycles To 80% Of Health

2,500~3,500 Cycles


500~800 Cycles


LiFePO₄ batteries can not only reach 3,000-5,000 cycles or more, they can reach 100% depth of discharge (DOD). Why does that matter? Because that means, with LiFePO₄ (unlike other batteries) you don’t have to worry about over discharging your battery. Also, you can use it for a longer period of time as a result. In comparison, lead acid batteries last only 300-400 cycles. The high-quality lithium iron phosphate batteries used in the mid-to-high-end power station of BLUETTI can reach 3,500 charge-discharge cycles.

lfp vs nca vs ncm


LiFePO₄ batteries are non-toxic, non-contaminating, and contain no rare earth metals, making them an environmentally conscious choice. However, NCA batteries contain nickel, cobalt; NCM batteries contain nickel, cobalt, manganese, the mining of these metals has caused damage to our environment.

Why You Should Choose

Safest lithium-ion
Battery by far.

LiFePO₄ battery is inherently safer than NCM batteries in its greater thermal and chemical stability, making it less prone to explosions or fires. Ideal for home use and off-gird living.

Longer lifespan
Without compromising

BLUETTI LiFePO₄ batteries live up to 5000 cycles at 80% depth of discharge. Say you use 4KWh a day on a 2000Wh power station with solar panels hooked, NCA/NMC battery holds almost a year with 2 cycles a day while the lithium iron phosphate battery offers you at least 4 years.

Higher energy density
For higher charging
& spatial efficiency.

The energy density of LiFePO₄ has now reached 160Wh/kg from previous 90 Wh/kg in just few years and will be expected to exceed 180Wh/kg that NCM packs own in future.
