I purchased 3 150 AH lithium batteries. All the batteries have built in Bluetooth. However and I mean a big HOWEVER! The iPhone app will only show the first two batteries I connected to Bluetooth. It will not connect the third battery. I can understand reading only one Bluetooth battery at a time but come on. You should be able to add as many batteries that you have Bluetooth space for. I believe my iPhone can have 256 different Bluetooth connections. Come on guys please fix this app so I can add more batteries. Or better yet give us an app that shows all the batteries at once.

This is a fairly basic app that connects easily to my 3000w all-in-one solar inverter. It gives what appears to be accurate information; however, it also disconnects after about a minute requiring frequent refresh if you are trying to catch peak output—a feature this app lacks. It also lacks the ability to add capacity beyond 100ah and usually fails anyway. Recently changed time zones on my phone around midnight (from 1230 am to 1130 pm). This wasOn my peak collection day thus far and the change caused all of that day’s data to be wiped out. Disappointed in the app but their budget priced equipment works well doing all I ask it to. Hopefully they will do some upgrades.

I use this app to connect to a Eco-worthy 280ah battery for my camper van. That connection allows me to see some basic info such as net charge/discharge rate, time of use, etc. I wish this particular battery had the ability to change some parameters, especially the freeze protection point which is way too low. The connection was easy and for my limited scope of a single battery, it works well enough. No language issues.

Tried multiple different times to scan QR codes on the batteries for the built in BMS; not only does it not work your device will not pop up on the bluetooth to connect a different way. Cant get ahold of customer service, so much for 24/7 support. Honestly a flop and i was excited for easy management. The app itself is infuriating, let alone the system an issues i can not resolve with out a tech. But i cant get anyone on the phone.
