Can you mix different capacity lithium batteries?

Yes, you can mix different capacity lithium batteries, whether a normal 12V 100Ah battery or a Lithium server rack battery. You can combine different capacity batteries in parallel. You cannot combine different capacity batteries in series. There are a few points you need to consider when wiring in parallel. Let’s explore these three points.

Why does lithium ion have a higher voltage than LiFePO4?

This is because lithium-ion has a slightly higher voltage than LiFePO4. The batteries get charged all at the same time. A smaller battery will be at the same voltage as a larger battery. Therefore, the state of charge will be equal in all batteries. Let me explain with a diagram where all the batteries are charged to 70%. 2.

Can lithium batteries be connected in parallel?

Lithium batteries can indeed be connected in parallel, and this method is commonly used to achieve higher capacity and extend the runtime of a battery system. By connecting two or more lithium batteries with the same voltage in parallel, the resulting battery pack retains the same nominal voltage but boasts a higher Ah capacity.

Why do lithium ion batteries need to be connected in series?

To meet the power and energy requirements of the specific applications, lithium-ion battery cells often need to be connected in series to boost voltage and in parallel to add capacity . However, as cell performance varies from one to another [2, 3], imbalances occur in both series and parallel connections.

Can lithium ion be combined with LiFePO4?

It is not possible to combine lithium-ion with LiFePO4. This is because lithium-ion has a slightly higher voltage than LiFePO4. The batteries get charged all at the same time. A smaller battery will be at the same voltage as a larger battery. Therefore, the state of charge will be equal in all batteries.
