Best China LiFePO4 Batteries


Lithium iron phosphate battery chemistry is more stable at high temperatures and non-combustible even when mishandled. lithium iron phosphate battery safety lies in its less toxic nature also mitigates its risk of accidental poisoning, allergic reactions, and medical hazard.

Fast Charging

LiFePO4 batteries charge faster at a rate of 1C (up to 1 hour). A 20 amp charger can be used with a 23 Ah battery for a 1-hour charge rate. It would help if you charged your LFP battery when discharged up to 80% DOD (20% SOC) or immediately after use.

High-temperature Tolerant

LiFePO4 batteries can tolerate a temperature range from 5 to 45 degrees Celsius. Anything below 5 degrees celsius affects its charging rate, but it does not decompose at high temperatures.

More Lightweight

A typical LiFePO4 battery is 50% lighter than a lead acid battery of the same capacity and can be used without any problem due to this feature.


LiFePO4 batteries (LFP) have a lifespan of at least ten years. It lasts about 5000 cycles at 80% depth of discharge which is longer than other lead acid batteries.

Environmentally Friendly

LiFePO4 batteries are built with non-toxic materials such as copper, iron, graphite, etc. It comprise phosphate salts rather than metal oxides which have a lower risk of contaminating the environment.

China lifepo4 battery for Your Project

Sunly LiFePO4 battery pack factory uses electrochemical materials such as aluminum, cobalt, copper, carbon, etc., as its anode or cathode electrode to design lithium battery systems of special applications, such as lifepo4 solar battery solutions, regarding voltage level, lifetime, SOC, and safety.

Finding LiFeP BaO4ttery Manufacturer: Things to Know

While both battery types fall under the category of lithium-based batteries, the difference is in their performance. Custom lithium ion batteries have a higher energy density of 100 Wh/kg to 265 Wh/kg, while LiFePO4 batteries have a density of 90-165 Wh/Kg. Even with this difference, LiFePO4 batteries are still considered better than lithium-ion because of their stable chemical and thermal property, long lifespan, low cost, portability, lightweight, etc. For more info check our guide what is lifepo4 battery
