Lithium Batteries

There are several types of Lithium batteries. Here at altE, we carry what we feel is the best candidate for renewable energy storage. The advantages of Lithium Phosphate batteries (as compared to Lead Acid for example) are that no maintenance is necessary, they can operate at very low temperatures without affecting capacity, and they are much safer. They also offer one of the lowest lifetime costs per kWh cycle.

Lithium Deep Cycle Batteries

Lithium Battery Storage

Lithium batteries are a great choice for solar power systems. They are especially forgiving when it comes to the level of discharge they will tolerate. Said another way, you can safely go up to a 100% depth of discharge (DoD) while maintaining nearly 98% efficiency. Many of the lithium deep cycle batteries we offer have a cycle life north of 10,000 cycles (80% DoD)!

Watch our video with Jordan from SimpliPhi Power where we discuss their company and the lithium ferro phosphate (LFP) deep cycle batteries they manufacture.

KiloVault Lithium Solar Batteries

Check out our video on the KiloVault line of lithium solar batteries. The KiloVault line is specifically designed for the residential energy storage market—both for off-grid and for battery backup systems. They can be wired in 12V, 24V and 48V configurations. They are maintenance free and have a 5,000 cycle life when discharged to 80% depth of discharge. Click to watch and learn more about the KiloVault!

Monitoring Your Lithium Batteries

Many lithium solar batteries come equipped with a built in battery management system (also known as a BMS). Battery management systems are designed to protect batteries by ensuring they are operating within the manufacturers' desired parameters. Parameters the BMS are monitoring could include state of charge, voltage or temperature of the battery. It’s no secret there is a higher initial capital outlay when buying lithium deep cycle batteries. The BMS is a great built-in feature because it automatically helps protect the investment you made in the battery by shutting down the battery if the BMS detects something is wrong.

Battle Born Solar Lithium Battery

In addition to being easy to work with, lithium deep cycle batteries are also lighter than other deep cycle battery options. Depending on the amp hours and the voltage of the specific battery they can weigh between 16.2 lbs (7.35 kg) to 32.65 lbs (14.8 kg). This makes them a solid option for mobile applications like marine or tiny solar houses.

Simpliphi Power Lithium Ferrous Batteries

SimpliPhi manufactures lithium ferro phosphate (LFP) that are virtually maintenance free. Their lithium batteries come in a variety of amp hours depending on your storage needs and are available in 12 Volts, 24 Volts and 48 Volts. Watch our video to learn more about lithium deep cycle batteries.

Lithium batteries work well in solar systems with battery backup because they can be charged up and do not require maintenance.
