I was recently attempting to connect to my battery in an area where I was surrounded by RVs with lots of Bluetooth. When there are many Bluetooth devices, the list of Bluetooth devices adds the same device over and over to the list. Further there seems to be a limit to the total number of devices you can handle from the list of Bluetooth devices you get from the OS. What I mean by that is that I couldn’t see the battery’s Bluetooth signal in the app. When I turned off my iPhone and Apple Watch, I was able to see the battery. I think this is because you have a hard limit on the number of devices and my battery was after the limit…until I switched off a couple of devices. I’d be happy to discuss this further, please respond to this review with contact info & I’ll happily provide more info. If this app is open source, I’d also be happy to fix the problem. (Or if you could release the source to me).

I am also having my batteries reading 84 and 81 % routinely these are 200ah and when I first set them up one was 203ah other 198ah after first charge. These are on a charger on my boat and have never been run down they are six months old. O noticed this app doing this from day one. There is something wrong between the app and what the BMS is saying. The only time the app would read 100% was when I charged the batteries until BMS shut off on each battery then the app would magically read 100% at 203ah and 198ah. Please fix this real time status something is either wrong with the app or what the BMS is saying.

With this update they have removed the battery health and actual capacity from the screen. I believe this is to hide problems with the batteries they are selling. I have received two different batteries from them with less than the design capacity. Both of them showed in the app with 84% health and 175ah capacity. Buyers beware!

App doesn’t work. Just says we’re sorry 🤦🏻‍♂️
