Can solar container lithium battery packs be mixed

Can solar container lithium battery packs be mixed

Yes, you can mix different capacity lithium batteries, whether a normal 12V 100Ah battery or a Lithium server rack battery. They are a little over 2 1/2 years old. I'd like to add another one next spring. However, it seems I remember reading in the past that lead acid batteries of different ages should not be mixed. During charging, the voltage increase will be consistent and within the charger's limits. This can force the battery management system (BMS) to shut down the entire system based on the weakest link, significantly reducing available capacity and causing other batteries to remain. . These LiFePO4 lithium batteries are commonly used in applications requiring steady energy delivery and high durability, such as renewable energy systems, Recreational Vehicle, and backup power solutions.
