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.
Awesome Battery, Trash App
Probably one of the best values in lithium batteries out there, the product is soured by their absolute trash quality of an app. Gimmicky graphics, crashes all the time, and overall horrible UI/UX compared to other batteries. History tab is utterly useless as it default loads to the day you installed the battery, not the last couple hours like victron.
Get your app together epoch,

460 V2
I bought this great battery however the app is horrible. It says be within 10 meters to connect but I have to be within 3 ft or the device can’t find the battery. Another problem is it automatically turn off after a minute so when your looking at different screen you have to go back and turn it on again. I wish I would have bought the cheaper battery and put an eviction shunt and saved money. Also can’t update because it wants a password that’s supposedly not required. Horribly disappointing

Please filter based on MAC address prefix
The app is annoying in that it detects every Bluetooth device in our RV. This is silly, because Epoch could easily filter based on the MAC address prefix(es) they use in their batteries. Just a few lines of code would make this app far more usable. The glitzy graphics and animation are not necessary. Just present the information simply and reliably, please.

This app is not documented anywhere
I like my Epoch battery, but this app displays data that nowhere on earth is documented on what most of it means. This is absolutely infuriating.
App is not documented
This app is not documented at all. I cannot understand why my battery heater isn’t working. Nothing in the battery manual states how it works and this app has no explanation. Further, this link supplied in this app for my battery isn’t even the correct manual. Epoch needs to re-evaluate this entire app and documents its use so I can get the most out of my $1500 battery and stop screwing around.

Bad battery information
That app used to work, but now I have no idea where my battery state of charge stands. Seems like good batteries, but horrible app now. For so many Epoch customers this Needs to fix quick.
12/19/24. Update
Finally got an update for the epoch app. Charging time and discharge time have been fixed. The App load time is faster. Thank you

Can’t connect to the Bluetooth
I read the reviews and was like how bad can it be, connecting to Bluetooth is about as basic as it gets. Apparently not…. The app is shockingly bad. It connects to the Bluetooth and then immediately disconnects. I’ve tried multiple times with no luck. Absolutely terrible app. Again connecting to Bluetooth is as basic as it gets for 20 years now. Please fix!?!

Trash
The new app is complete garbage. Don’t know how whoever designed the update thought it was a good update. Gives you useless info and none of the info you would need for the battery.
Cannot save battery connection
The app provides valuable information on the batteries and works well with multiple batteries. However, the battery connection and name is not saved so you have to re-select the batteries every time you close and reopen the app.
Furthermore, it is unable to filter out non-epoch devices so all the wireless devices in the area show up in the list making it even more inconvenient to find and select the right devices.
This can get very annoying when you want to use the app frequently to check the status of your batteries. This should be a relatively easy programming fix to save the device address so hopefully this will be fixed soon.

Bring back the old app
The batteries are rock solid, but I agree with most of the posts about the new app. The old app had a feature to tell you how many hours minutes were remaining at the current discharge rate. Also showed you how long it would take once you’re charging to charge up the battery. Those two statistics were awesome to have. Please bring them back!
Also, what is the “Advanced setting” password? In that part of the app, (once the password is known), does that area give more data or configuration parameters? Your user manual doesn’t talk about this part of the app.

Does not always reflect true battery charge.
My app was showing 70% left on the battery yet the battery was dead. At no time did the app show that the levels were declining. Battery died, app read 70%.
I would not depend on this app especially if you use it in situations such as electric water motors. It left me stranded.

Not working at all !!!
You guys are a complete disaster, for 3 months your app is not working at all, what are you doing there?????

Epoch app
This app is very helpfull to me as I am now able to see how many amps appliances or electrical consumers are using. It also gives me the charge rate the solar system is charging at and also the charge status of the battery. Love it
They ruined it!
This app used to be useful. It used to give the time till discharge or charge. It used to give all the details and info on one screen. Now it is all graphics that are useless! If it doesn’t get changed back to something that resembles the old app I will never purchase another epoch battery again.
