Calculation method
Calculation method
Series cells (count)
Choose smallest series count meeting nominal voltage, then smallest parallel count meeting nominal energy; obey entered count limits. No maximum-voltage, current, mechanical or BMS compatibility design.
Parallel cells (count)
Choose smallest series count meeting nominal voltage, then smallest parallel count meeting nominal energy; obey entered count limits. No maximum-voltage, current, mechanical or BMS compatibility design.
Nominal pack voltage (V)
Choose smallest series count meeting nominal voltage, then smallest parallel count meeting nominal energy; obey entered count limits. No maximum-voltage, current, mechanical or BMS compatibility design.
Nominal pack energy (Wh)
Choose smallest series count meeting nominal voltage, then smallest parallel count meeting nominal energy; obey entered count limits. No maximum-voltage, current, mechanical or BMS compatibility design.
Total cells (count)
Choose smallest series count meeting nominal voltage, then smallest parallel count meeting nominal energy; obey entered count limits. No maximum-voltage, current, mechanical or BMS compatibility design.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Choose smallest series count meeting nominal voltage, then smallest parallel count meeting nominal energy; obey entered count limits. No maximum-voltage, current, mechanical or BMS compatibility design. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
