Passive balancing isn’t as “simple” as it looks
Many assume passive balancing = safe + reliable.
But in practice:
Heat dissipation becomes a bottleneck
Balance current is often too low for large packs
Timing strategy matters more than hardware
📌 Observation:
In multi-cell packs, imbalance is often driven by temperature gradients, not capacity differences.
👉 Design tip:
Balance control logic > resistor selection.
