Editorial interest 77/100 Selection signal · not a rating of the site

An IoT system for monitoring lithium-ion batteries that estimates cell health and remaining life from the voltage response to a brief load step.

Landing page captured for the 2026-10-31 issue.

For: Lithium-ion battery operators and monitoring teams
Worth noticing: The stated sampling rate is 1 kHz, and one discharge record contains 4.7 million samples.

Field notes

The described node periodically applies a small extra load, then records current and cell voltages without removing the battery for a test-stand discharge. Readings can travel over Wi-Fi, Ethernet, or RS-485; the server extracts resistance-related features at three points after the current step. The site says its remaining-life forecast is refined with each new measurement and defines end of life as 80% state of health.
