Design Notes
- Cell measurement accuracy is specified over temperature — calibrate the sense path if the gauge reports state of charge rather than raw voltage.
- Balance current is limited by the bleed resistor and the pack wiring; check the resulting balance time for the capacity mismatch you expect.
- Protection thresholds should sit inside the cell maker's absolute limits with margin for measurement error.
- Keep the sense lines separate from the power path to avoid IR drop corrupting readings.
