18650 Battery Pack Calculator and Planner
Select a cell from the cell database
Use this autocomplete search functionality to find your specific cell in order to pre-populate the values that we have for that cell.
Single cell information
Enter information on a single cell into the input fields to receive results for a single cell. Results will automatically generate every time a value changes and there is enough information to calcualte results.
The C-rate will be used down below at pack level calculations, so make sure you fill this section out.
Pack level information
Enter information related to your up-and-coming pack to get all kinds of information on the pack.
The C-rate, voltage, and capacities from the single-cell step will be used to calculate information in this step. Make sure that you fill out the fields above to get accurate results in this section.
Virtual battery life estimator
This section allows you to get an idea of approximately how long the pack you are building will be able to run.
If you plan on running something that consumes 1000W, you can now figure out how long the pack will last while providing that power.
Pack weight and cell cost
This section estimates the cost and weight of the pack based on cell count, single cell weight, and cost per cell.
The series and parallel information from the above step are used to calculate this information, so make sure you fill out the above step first.
