Features & Capabilities

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.

User Reviews

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.

Yikes. Echoing what everyone else is saying on here - the batteries are great but the app is garbage. It doesn’t auto-connect to bluetooth and frequently drops signal, meaning you have to keep selecting the batteries in the device list over and over again. It’s never once remembered my devices. Definitely a software issue.

I’ve been extremely impressed with the Epoch 460Ah 12V LiFePO4 battery. The capacity, performance, and overall build quality are outstanding. For anyone needing serious off-grid power for an RV, van build, backup system, or mobile work setup, this battery delivers exactly what it promises. The 460Ah capacity provides a massive amount of usable energy, and the LiFePO4 chemistry offers the long cycle life, stable voltage, and safety that lithium batteries are known for. One of the things I noticed immediately is how well the voltage holds under load. Even when running larger loads through an inverter, the battery maintains consistent output without the voltage sag you typically see with lead-acid batteries. Another big advantage is the simplicity of having so much capacity in a single 12V battery. Instead of wiring multiple batteries in parallel, this one unit provides an enormous energy reserve while keeping the system clean and straightforward. One of my favorite features is the Epoch iPhone app. It connects quickly via Bluetooth and gives you detailed real-time information about the battery, including state of charge, voltage, current, temperature, and remaining capacity. The interface is clean, responsive, and easy to understand. Being able to monitor the battery directly from my phone makes managing the system much easier, especially in a mobile setup. Charging performance has also been excellent. The battery accepts charge quickly and efficiently, whether through a DC-DC charger, inverter charger, or generator setup. Overall, the Epoch 460Ah battery is an absolute powerhouse. Between the massive capacity, reliable performance, and the excellent mobile app for monitoring, it’s one of the best lithium battery options available. I would absolutely purchase it again.

This app needs some attention. It should not show every Bluetooth device in existence; it should filter Epoch only signals. It should also employ a BLE non-exclusive connection, that way I don't have to go find my tablet and disconnect it if I want to view the battery stats on my phone. Thanks.
