Pack 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.

This list is by no means exhaustive. If you have cells that you would like added or find that we are missing data for some of the cells that we do have, please email us, or fill out a contact form.

Cell database made possible and initially compiled by Wolf @ the SLS.com forums

Enter your cell manufacturer or model number to search for your cell. Results will appear automatically as you type.

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.

Enter the voltage of a single cell in your planned pack and the rated & tested capacity of one cell.

Enter the C-rate & the charge/discharge current.

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.

Enter the intended series and parallel cell numbers of the pack you are going to be building.

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.

Enter the amount of watts you expect to be drawing off of the pack to figure out how long that pack would last before needing a recharge.

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.

Enter the weight per cell, in grams, and the cost per cell to calculate overall pack weight and cell cost.
