Battery Bank Series and Parallel Calculator
Inspect ideal bank voltage, amp hours and energy from identical battery modules.
Open this toolSeries and parallel connections change battery bank voltage and amp hours in different ways.
Enter identical module ratings and the proposed arrangement. Compare the ideal bank values before checking the manufacturer's permitted configurations.

How to use
- Enter module nominal voltage and module capacity.
- Enter modules per series string and parallel strings.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why use this tool
The arithmetic view helps distinguish added voltage from added parallel capacity.
Before relying on the result
Arithmetic assumes identical compatible modules. BMS, permitted series or parallel arrangements, protection and balancing require manufacturer and installer review. This is not wiring approval.
Tool limitations
Arithmetic assumes identical compatible modules. BMS, permitted series or parallel arrangements, protection and balancing require manufacturer and installer review. This is not wiring approval.
Questions
Is the arrangement approved for wiring?
No. Module compatibility, protection, balancing and manufacturer limits require qualified review before installation.
What should I check before using Battery Bank Series and Parallel Calculator?
Check Module nominal voltage, Module capacity, Modules per series string and Parallel strings. Use the exact units shown beside the controls and replace any example values with your own inputs.
