💡 How often should you measure lithium and nickel based battery stacks under load?

It is handy to watch active voltage curves during heavy use to protect your investment.
- Track minimum drop rates to identify dead cells before they ruin full projects.
- Compare maximum recovery values after rests to gauge true remaining reserve capacity.
- Log repeated cycle data to decide when swapping worn packs saves more time than fixing them.
