8 lithium iron phosphate battery packs connected in series

What should be considered when connecting LiFePO4 batteries in series?

When connecting LiFePO4 batteries in series, the following should be considered: Uniformity: Just like parallel connections, it is necessary to use cells or batteries with the same specifications, including capacity and age, in a series connection.

Are LiFePO4 batteries safe?

LiFePO4 (Lithium Iron Phosphate) batteries are used widely for energy storage or backup. And it's no wonder. Afterall, they are safe, have stable chemistry and they last long. But sometimes, you may need to combine several batteries together to get the most of your setup. You may either connect in series or parallel, depending on your need.

Why are lithium batteries connected in series?

Lithium batteries are connected in series when the goal is to increase the nominal voltage rating of one individual lithium battery - by connecting it in series strings with at least one more of the same type and specification - to meet the nominal operating voltage of the system the batteries are being installed to support.

Can LiFePO4 batteries be connected in parallel?

Due to their design, you can combine LiFePO4 batteries to meet your specific energy needs. Often, people make this connection to: When batteries are connected in parallel, the voltage stays the same, but the capacities (Ah) are added. For example: Two 12V 100Ah batteries in parallel is a 12V 200Ah system.
