RC LiPo Battery Power & Configuration Calculator
What this calculator does
The RC LiPo Battery Power and Configuration Calculator helps you plan how one or more LiPo packs will behave in an RC setup. Battery configuration can be confusing because series wiring increases voltage, parallel wiring increases capacity and current sharing, and the final setup load depends on how the model uses that power. This calculator is useful for cars, boats, EDF jets, airplanes, and charging or bench planning. It helps estimate total voltage, capacity, wattage, current demand, usable energy, and how hard the battery is being asked to work. Enter the cell count, capacity, C rating or current demand, and whether packs are used alone, in series, or in parallel. Example: two 3S 5000mAh packs in series become a 6S 5000mAh setup, while two in parallel remain 3S but become 10000mAh. Use this page before changing pack wiring so you can avoid confusing voltage, capacity, and current capability.
In practical terms: It explains and calculates how LiPo pack wiring affects voltage, capacity, wattage, current sharing, and usable energy.
How to use it
Enter the pack count, cell count, capacity, and configuration. Compare series and parallel wiring to understand what changes and what does not.
Example calculation
Check whether two 3S packs should be wired in series for 6S voltage or in parallel for longer 3S runtime.
FAQ
What changes when LiPo packs are wired in series?
Series wiring adds voltage while capacity stays the same. Two 3S 5000mAh packs in series behave like one 6S 5000mAh pack.
What changes when LiPo packs are wired in parallel?
Parallel wiring keeps voltage the same while capacity and current sharing increase. Two 3S 5000mAh packs in parallel behave like one 3S 10000mAh pack.
Why does wattage matter more than voltage alone?
Wattage combines voltage and current. A setup can use the same current at a higher voltage and place much more total power through the system.
Can this calculator tell me if my battery is safe?
It helps estimate load and configuration, but final safety depends on pack condition, connector quality, wire size, cooling, and real measured current.
