Notes
Looking at the comparison chart, it’s clear that the six batteries are similar in many areas. But there are some notable differences and certain standout features in some of the batteries.
Here are some quick notes to help you choose the right one for your setup.
Pros & Cons Of LiFePO4 Batteries
The Good
LiFePO4 batteries are increasingly becoming the energy storage of choice for solar systems, RVs, golf carts and other applications that require a deep cycle battery.
They are not only replacing older lead acid batteries, they are also more popular than other types of lithium-ion batteries.
LiFePO4 batteries, also called lithium phosphate, have several advantages over other battery chemistries.
Downsides of LiFePO4 Batteries
The biggest downside of LiFePO4 batteries is the price. They usually cost more upfront compared to other types of lithium batteries. They are much pricier than lead acid batteries.
Some brands can cost up to $1000 or more.
That said, they offer better value for money over the long term since they last much longer than lithium-ion and lead acid batteries.
While you’ll need to replace a lead acid battery every 2-3 years and a lithium-ion battery every 3-5 years, a LiFePO4 battery can last up to 10 years.
The other downside of LiFePO4 batteries is that they tend to be heavier and bigger compared to lithium-ion batteries.
That’s because they have a lower energy density.
