The problem
A capacity discharge test or a cell impedance survey is run against IEEE 450, 1188 or 1106 depending on the chemistry, with manufacturer thresholds and temperature corrections on top, while the engineer manages arc-flash and hydrogen hazards from a paper checklist. What she noticed on site reaches the maintenance system days later, when the paperwork is filed, if it reaches it at all.
What I built
A guided workflow that picks the IEEE procedure for the battery type, trends impedance against the baseline as the readings come in, watches each cell during discharge for reversal or a sudden fall, corrects capacity for temperature, and produces the report to the standard before the engineer leaves site. A Telegram bot takes voice or text notes from any engineer on the crew and feeds them through the same pipeline, so no laptop is needed.
The logic flow

What it returns
The checklist cannot be skipped because the workflow will not advance past it, a failing cell is flagged during the discharge rather than in next month's spreadsheet, and the report exists when the engineer drives away. The observations reach ERPNext the same day.

Every part of it is open source and self-hostable. What I bring is the failure record and the judgement about where your gates should sit.
