LiPo Battery Calculator
Calculate LiPo battery energy, runtime, and C rate for drones, RC models, and high-discharge battery packs where weight and current delivery matter.
LiPo Energy and C Rate Tool
Enter pack series count, battery capacity, C rating, and load to estimate LiPo pack voltage, watt-hours, maximum current, and runtime.
LiPo Pack Estimator
This calculator uses 3.7V nominal cell voltage and common LiPo C-rate math to estimate pack energy and discharge capability.
Calculation Results
These results show nominal pack voltage, energy in watt-hours, maximum continuous current from C rating, and estimated runtime if load is entered.
Educational Estimates Only: LiPo batteries are high-performance packs that require correct charging, storage, and handling. Actual runtime, safe current, and cycle life vary by pack quality, temperature, voltage sag, discharge profile, and manufacturer specifications. Verify with datasheets for critical use.
LiPo Basics
LiPo batteries are widely used where low weight and high discharge rate matter, especially in drones, RC aircraft, RC cars, and similar high-performance systems.
LiPo stands for lithium polymer battery. These batteries are popular in drones and RC applications because they can provide high current while staying relatively lightweight, but they also require careful charging and handling.
A typical LiPo cell has a nominal voltage of 3.7V, and common pack ratings often range from about 20C to 100C depending on the application. Because LiPo packs can deliver very high discharge current, proper charging, storage voltage, and physical handling are important for safety.
For example, 3S 5000mAh stores 55.5Wh, 4S 6000mAh stores 88.8Wh, and 6S 10000mAh stores 222Wh using nominal pack voltage.

What is a LiPo battery?
Lithium polymer battery used where weight and discharge rate matter. It is common in drones, RC aircraft, and other lightweight high-power devices.
Is LiPo safe?
LiPo can be safe when charged, stored, and handled correctly, but it is generally more fragile and handling-sensitive than LiFePO4.

Is LiPo safe?
Safe when charged, stored, and handled correctly, but more fragile than LiFePO4.
What is LiPo nominal cell voltage?
LiPo cells commonly use 3.7V nominal voltage.
What does C rating mean?
C rating describes how quickly a battery can be charged or discharged relative to its capacity.
How do I calculate max current?
Multiply battery capacity in Ah by C rating to estimate maximum continuous current in amps.
Why are LiPo batteries used in drones?
Because they offer light weight and high discharge capability, which are important for flight performance.
How should LiPo batteries be charged?
Use a charger designed for LiPo packs, balance-charge the cells, and never leave charging batteries unattended.
What is a common LiPo charge rate?
Many LiPo packs are commonly charged around 1C unless the manufacturer states otherwise.
What does 3S, 4S, or 6S mean?
It means the number of cells in series, which determines the pack voltage.
Is this useful for RC and FPV?
Yes. It is useful for drones, FPV packs, RC cars, RC planes, and other high-discharge applications.
