How this service works
Battery bank layout (series and parallel counts) and runtime from load, voltage, Ah, depth of discharge and efficiency.
Output
Returns the battery bank configuration including number of series cells per string, number of parallel strings, total bank voltage, total and usable amp-hours and watt-hours, calculated runtime in hours, effective efficiency, and a human-readable summary with any advisory reasons or disclaimers.
Example use cases
Off-grid cabin power sizing
“I'm building an off-grid cabin with a 600W load running on a 24V system using 12V 200Ah batteries. Assuming 50% depth of discharge and 90% efficiency, how many batteries do I need in series and parallel to get 8 hours of runtime?”
RV battery bank runtime check
“I already have 2 parallel strings of 12V 100Ah lithium batteries in my RV. With a 300W constant load, 80% depth of discharge, and 100% efficiency for a DC system, how long will they last?”
Solar backup system design
“Help me size a 48V battery bank for a 1200W backup load using 12V 150Ah AGM batteries. I want 10 hours of runtime, with 50% depth of discharge and 85% inverter efficiency — tell me how many strings I need in series and parallel.”
Technical details
Endpoint
GEThttps://electrical-calc.x402tookit.com/battery-bank?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compute battery bank topology (series and parallel counts) and expected runtime for a DC or inverter-fed load. It is purpose-built for off-grid, RV, solar, and backup power design scenarios where you know your load watts, system voltage, individual battery specs, and desired depth of discharge — and want a validated configuration with usable energy and runtime figures without doing the math manually.
Side effects
- Missing required parameters (loadW, systemVoltageV, batteryVoltageV, batteryAh) returns a 400-level error
- systemVoltageV not a whole multiple of batteryVoltageV results in an invalid configuration or error
- Conflicting runtimeHours and parallelStrings — runtimeHours takes precedence, parallelStrings is ignored
- Zero or negative values for electrical parameters produce undefined/error results
- Very low efficiency or DoD percentages may yield impractically large battery counts
