Initially, batteries with different capacities, types, and usage histories may not significantly impact performance. However, over time, the dissimilar electrolytes and variations in charging and discharging processes can lead to battery damage. Considering technical aspects, I personally advise against the following practices: Mixing used batteries with new ones. Combining batteries of different capacities in parallel or series connections. Using batteries from different brands. Mixing different battery types. Advanced inverters often come equipped with smart battery management systems (BMS) that recognize connected batteries. However, BMS can sometimes become confused about the battery types, leading to potential damage to command boards." Remember to handle battery combinations with care to ensure optimal system performance and longevity.
