Team

FLE was founded in 2024 on the principle of doing more with less. Our all-weather, ultra-high power and fast charging, lithium-ion products allow you to build the perfect battery for your application. No wasted capacity, less weight, no unnecessary risk, smaller environmental footprint, and lower costs across the board.

We value cooperation, science, and fairness. We look forward to working with you, or for you, to deliver the best product possible.

Together.
