🔬 Series Strings vs. Parallel Groups: Do you know how cell mismatch affects them differently?
In Series: The lowest-capacity cell sets the ceiling for the whole string, leaving usable energy trapped in stronger cells.
In Parallel: Current splits based on internal resistance. A lower-resistance cell pulls extra current, works harder, and creates an accelerated aging feedback loop.
This is why rigorous, three-tier cell matching (Voltage, Capacity, and IR) before pack assembly is non-negotiable for utility-scale systems.
Rahul Jalthar breaks down automated grading, top-balance vs. bottom-balance sorting philosophies, and how to audit your supplier’s incoming cell test data.
