## Description

Epoch Li-ion is a Chrome extension that uses Bluetooth Low Energy to locate Epoch batteries nearby and stream real-time data. It displays key metrics such as voltage, current, power, internal resistance, and temperature in an instrument-style dashboard, while flagging alarms when limits are exceeded. The extension also shows per-cell voltage differences and cell balance status to help you monitor safety and performance.

It records warnings and protection events as they occur and facilitates quick access to each battery's status, aiming to extend battery life and improve stability of Li‑ion packs. Connect, scan, refresh, and view battery health at a glance for safer, more reliable operation.

## Review summary

Users generally appreciate real-time monitoring and multi-battery support, but Bluetooth reliability, device filtering, and update-driven UX regressions hinder consistent use. Common complaints include auto-connect failures, inaccurate readings, and loss of useful metrics like time-to-discharge/charge. When the app works, it provides valuable insights and is handy for mobile setups, but reliability and UI flaws consistently overshadow its benefits.

### Pros

- Real-time battery monitoring on iPhone (SOC, voltage, current, temperature, remaining capacity).
- Ability to monitor multiple Epoch batteries from a single app.
- Quick Bluetooth connection with a clean, responsive interface when connected.
- Provides data beyond SOC, including information about battery cells and health.
- Handy for mobile/off-grid setups, making it easy to view status on the go.

### Cons

- Bluetooth connectivity is unstable; auto-connect often fails and devices are forgotten.
- App lists all nearby Bluetooth devices and lacks filtering to Epoch devices, causing clutter.
- Recent updates regressed usability by removing key metrics (e.g., time-to-discharge/charge) and adding a less useful UI.
- Data can be inaccurate or not reflect reality (e.g., 0% readings or dead battery reported).
- App reliability issues (crashes) and not saving which battery is selected across sessions.
