Annoying
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.

Great Battery!!
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.

It works but it needs attention.
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.
kinda barebones
Shows SOC as percentage and as voltage. Shows individual cells. Shows temperature probe readings. Shows amps in/out. What do I dislike? The bluetooth. It disconnects on a whim and then even requires that I manually disconnect if I want to see the battery from another device (tablet, phone) it's clunky. The battery itself works well.

Horrible app
This app is useless. I’ve had it and my battery for about a month. Seems like the app just got worse and worse. Starting today, Bluetooth won’t even connect even with my phone on the gauge that has the Bluetooth module in it.
