For the lowest cost per kWh cycle and highest energy density, lithium solar batteries are the best choice for renewable energy systems with storage needs.
Lithium solar batteries are more specifically called lithium iron phosphate batteries (LiFePO4 or LFP), and they offer numerous advantages over flooded and sealed lead acid batteries when used in renewable energy systems. Longer life, wider temperature range, true deep cycling, and safety are just the beginning. See below for even more reasons to choose lithium iron phosphate batteries over the alternatives, or browse our selection of 12V, 24V, and 48V lithium solar batteries for sale from KiloVault, SimpliPhi, Battle Born, and other top manufacturers.Read more +

To understand why lithium iron phosphate batteries have become the new gold standard for renewable energy systems, it’s helpful to compare them to the previous standard battery type for these applications - lead acid.
Compared to lead acid, lithium solar batteries are:
It’s also helpful to compare lithium iron phosphate batteries to an alternative type of lithium ion batteries for solar and renewable energy systems - lithium nickel manganese cobalt (NMC).
Compared to NMC, lithium iron phosphate batteries are:
It should be clear by now that lithium batteries for solar energy storage are superior to lead acid batteries in every way except for the higher upfront cost (though when it comes to lifetime cost per kWh cycle, lead acid can’t touch them). Here are some specific applications where lithium solar batteries really excel and why:
Under the umbrella of "lithium batteries", there are both lithium metal batteries and lithium ion batteries. Lithium metal batteries are not rechargeable, so they’re not relevant for solar power systems.
Under the umbrella of "lithium ion batteries", there are several types - each with its own set of pros, cons, and specific use cases. Today, three types are by far the most common, and they have different specialties:
