Why LiFePO4 Batteries Are the Best Batteries for Storage Power Storage.     Date:2022-09-20

As you can see, the positives of LiFePO4 batteries greatly outweigh the negatives. Their efficiency and consistent energy output make it a clear winner. Let’s go over the specifics. 

Long Battery Life

Battery life is where LiFePO4 batteries make up for the higher initial cost. A high-quality LiFePO4 like Dragonfly Energy is designed to last 3000-5000 cycles of deep discharging and still retain 80% of its original capacity. This is critical for a solar system because the batteries are used every single night and recharged every day.

In reality, the battery life cycles are even higher as most discharges are not full. 10,000-15,000 cycles are common for LiFePO4 in a solar application making them good for many years.

Little to No Maintenance

Because our LiFePO4 batteries come with a built-in battery management system, they’re highly efficient. This also means that they require little to no maintenance. Even if you’re using your battery for RVing or marine capacities with constant movement and jostling, LiFePO4 batteries still hold up well.


LiFePO4 batteries also come with considerable weight savings. They generally weigh about one-third to one-half of what a lead-acid battery weighs. This means you can ramp up your battery bank since it takes two or three LiFePO4 batteries to equal the weight of one lead-acid battery. They also have more usable capacity, which maximizes their weight to power ratio.

Fast Charging Time

LiFePO4 batteries offer lower resistance, and they don’t require a float charging cycle. So they charge much faster than lead-acid batteries. When you’re relying on solar power, a battery that recharges faster is significant. If there are only a few hours of pure sunlight per day where you are, a shorter charge time is gold. 

This is an example of solar system power in watts charging a LiFePO4 battery. As the solar climbs for the first part of the day the battery rapidly takes the charge of almost 2000 watts. Notice that once it’s charged it immediately goes to a float charge. Other battery types taper off and can waste solar energy or not get fully charged if there is not enough sun.

Environmentally Friendly 

LiFePO4 batteries are non-toxic and recyclable. Many of us want to use solar energy for its environmental benefits, so it only makes sense to utilize solar battery storage that’s not detrimental to the environment. There are fewer gas emissions from them and no risk of acid spills.
