Design Notes
- Watch the voltage derating curve before sizing the bank.
- Series resistance and cell balancing affect usable life.
- Confirm terminal torque and busbar alignment at assembly.
- Cells in series need balancing — imbalance shortens the whole string.
- Keep the string voltage under the module rating at end of charge, not just nominal.
