Why use LiFePO4 cells

Safety and stability

LiFePO4 batteries are best known for their strong safety profile, the result of extremely stable chemistry. Batteries offer superior thermal and chemical stability which provides an increase in safety. Lithium cells are incombustible, which is an important feature in the event of mishandling during charging or discharging. They can also withstand harsh conditions.


Performance is a major factor in determining which type of battery to use in a given application. Long life, slow self-discharge rates, and less weight make LFP batteries an appealing option. Service life usually clocks in at fifteen to twenty years or longer, and runtime significantly exceeds lead-acid batteries. Battery charging time is also considerably reduced, another convenient performance element. So, if you’re looking for a battery for long life and quick charging, LiFePO4 is the answer.

When subjected to hazardous events, such as collision or short-circuiting, they won’t explode or catch fire, significantly reducing any chance of harm. When you choose a lithium battery and anticipate use in hazardous or unstable environments, LiFePO4 is likely your best choice.

Environmental Impact and Space Efficiency

LiFePO4 batteries are non-toxic, non-contaminating and contain no rare earth metals, making them an environmentally conscious choice. Also worth mentioning is LiFePO4’s space-efficient characteristics. At one-third the weight of most lead-acid batteries and almost half the weight of the popular manganese oxide, LiFePO4 provides an effective way to make use of space and weight. Making your product more efficient overall.

Compared to lead-acid and other lithium batteries, lithium iron phosphate batteries offer significant advantages, including improved discharge and charge efficiency, longer life span and the ability to life cycle while maintaining performance. LiFePO4 batteries often come with a higher price tag, but a much better cost over the life of the product, minimal maintenance, and infrequent replacement makes them a worthwhile investment and a smart long-term solution.
