Our Story

After years of working with lithium-ion battery packs, we identified a recurring challenge: many batteries that appear to have failed are otherwise mechanically and electrically sound, but are prevented from operating due to common protection or management-related issues. Existing solutions often focus on full component replacement, which is not always necessary.

This led us to develop the MDT-01, a straightforward diagnostic and recovery tool designed to help identify battery status and support appropriate maintenance or repair workflows. By providing clear diagnostic information, the MDT-01 offers an alternative to unnecessary full BMS replacement where lawful and technically suitable, helping extend the usable life of compatible battery packs.
