About Battery designer
Are you designing a lithium (Li-ion) battery pack for electric bikes, scooters, drones, or DIY projects? Stop doing manual calculations and use this app!
This app is the ultimate tool for designers, hobbyists, and professionals working with 18650 and 21700 lithium cells. Simply use the intuitive sliders to adjust the series (S) and parallel (P) configurations and watch your battery's key parameters change in real time.
🔬 Key App Features
Interactive Battery Design:
Adjust Size (S/P): Modify the number of cells in series and the number of cells in parallel with easy-to-use sliders.
Cell Selection: Choose the cell model (18650 or 21700), its individual capacity (mAh), and maximum discharge (A).
Automatic and Accurate Calculations:
Nominal Voltage (V): Calculate the total voltage based on the cells in series.
Total Capacity (Ah): Determine the total capacity based on the cells in parallel.
Energy (Wh): Obtain the total stored energy, essential for calculating performance.
Maximum Discharge Current (A): Know the maximum current the pack can safely deliver.
Weight (kg) and Dimensions: Get an estimate of the weight and physical measurements (Length, Depth, and Height) of your battery.
Performance Analysis:
Run Time: Calculate how long your battery will operate at full capacity. Simply enter the motor power (W) and system efficiency (%) to obtain the run time (h).
Detailed Quote:
Total Battery Price: Estimate the total cost of your project. Enter the price of each cell, the price of the BMS (Battery Management System), and the price of other materials (wires, casing, nickel) to obtain the final quote.
✨ Why use this calculator?
Save time and avoid costly mistakes.
Whether you're building a 15S4P pack for high voltage or a 24S9P pack for high capacity, our app provides you with critical data instantly. Know in advance the voltage, capacity, energy (Wh), and the impact your design will have on the dimensions and final price.
