Li-Ion BMS comparison, BMS selector

Parametric selector of off-the-shelf Battery Management Systems for large Li-Ion battery packs

By now, dozens of Li-Ion BMSs are commercially available, making a choice somewhat daunting.

This form allows you to chose the right, commercially available BMS, for your large Li-Ion battery pack application based on your needs.

Start by specifying the important parameters. If no results, undo less critical selections. To start from scratch, click the "Reset selections" button.

We have attempted to be as thorough and accurate as allowed by the information available on each BMS. Yet, we cannot held responsible for any incorrect or incomplete data. We kindly request you to bring any errors to our attention.

Even though this website is a service brought to you by Elithion employees, in preparing the data for this list we co-operated with competitors with the goal of avoiding any bias.
