Cost of Lithium Batteries (15 Solar Brands Compared)

In 2024, the cost of lithium batteries like LiFePO4 is going down while their durability is increasing. Now is the perfect time to replace your lead-acid battery and upgrade your solar generator or solar system.

Lithium batteries are the most versatile electricity storage available. They are:

  • Lightweight.
  • Offer great energy density (3-4 times higher than lead-acid).
  • Powerful (up to 2.4kW).
  • Perfectly fitted for solar energy storage.
  • Long-lasting (up to 10 years).

The cost of lithium batteries is primarily related to their capacity, expressed in Amps. hour (Ah) or watt.hour (Wh).

Cost of lithium batteries: A breakdown

The main lithium battery technology available on the market is LiFePO4. If you dissect them, you will find a few components that greatly dictate the overall lithium battery cost:

Let’s take a closer look at the two main components:

Battery management system (BMS)

A lithium battery cannot work without a BMS. This essential electronic component has 3 functions:

  • Monitor.
  • Regulate.
  • Protect.

The BMS is connected to each prismatic lithium battery cell. It ensures they’re all balanced and equally charged/discharged by controlling the charging and discharging current.

Additionally, It protects the battery from over-discharging and overcharging and ultimately prevents it from overheating by disconnecting the battery cells if needed.  

Note to our readers: All lithium battery brands featured in our article include a built-in BMS.

Prismatic lithium battery bells

Prismatic lithium battery bells are the basic building blocks of all lithium batteries. They have a standard voltage of 3.2V, and their capacity varies 50Ah, 100Ah, 200Ah, etc.

The quality of their material and manufacturing process affects their durability (number of cycles), robustness, and fast charge/discharge abilities.

Four prismatic lithium cells are connected in series resulting in a 12V lithium battery pack (4 x 3.2V = 12.8V).

Currently, LiFePO4 prismatic cells constitute 80% of the total lithium battery cost.

How to choose the correct lithium battery: 4-step process

Use the following four steps to help you choose your lithium battery:

1. The Capacity

Capacity is expressed in Ah. 100Ah means that your battery can provide a current of 100 Amps for one hour at a minimum voltage of 12V.

This discharge rate is called 1C: 100% of the capacity discharged in one hour. This is also equivalent to 10 Amps during 10 hours (10 amps x 10 hours = 100 Ah), a discharge rate of 0.1C: 10% of the total capacity discharge per hour.

A more accurate and absolute measurement of the capacity is the Wh. For example, a 12V, 100Ah battery has a capacity of 12*100=1200 Wh.

Note to our readers: A 12V, 100Ah battery and a 24V, 100Ah battery both have the same Ah, but the 24V stores twice as much energy: 
24 x 100 = 2400Wh.
In this article, we mostly use Ah because the batteries we selected are all 12V.

2. The Continuous Charge/Discharge Current

The BMS pilots the charge and discharge current. The higher, the better. Most BMS accept charging/discharging currents from 50 amps to 100 amps.

Lithium batteries allow for quick charging. A 100Ah battery can be charged in an hour with a current of 100 amps. However, in practice, a one-hour charge will give 80% of the total capacity, and the remaining 20% might last one more hour.

3. The Peak Discharge Current

Depending on your application, you may require a battery with large peak discharging currents. For example, to start heavy equipment such as a solar water pump.  

4. The Total Life Cycles

This is your battery’s durability. The most modern lithium battery models can reach up to exceed 5,000 charges/discharge cycles with a 10 years life duration.

Final thoughts

While the cost of lithium batteries has decreased significantly over the past few decades, it’s still a significant factor that affects the adoption of these batteries for various applications.

However, despite their initial higher cost compared to other battery technologies such as AGM and GEL, the overall cost of ownership is often lower due to their longer lifespan, higher energy density, and better performance. Additionally, advancements in battery technology and production processes are expected to continue to drive down the cost of lithium batteries in the coming years.
