Ratings and reviews

I run 3 of these for my battery bank in my van. Batteries are decent enough. App used to work GREAT until the latest update. I like that the charge/discharge time finally updated to hours and minutes. My problem is that once a battery is selected, it cannot be unelected. No matter what i do, the app always opens the same battery. I can no longer go back and select another battery.

app says my battery is 80º. also says it is at 100% charge when it is clearly not. battery works great, but either the app, or the hardware in the battery communicating with the mobile app is garbage. this battery is only about a month old. using my volt meter or victron battery monitoring app gives me more accurate information than the x2 app MADE FOR THIS BATTERY. for $600.00 battery, I am not impressed.

So far the app is useless. Just says "searching for device" "if not found try charging the battery" it is! Doesn't even show up on my Bluetooth devices list. 2 month old app and def. not ready for release. Now 8/20, 2 months later & the app is still just as usless Never connects to either of my batteries. Its amazing they chg $900 for these batts yet cant even make the app work. So much for a quaility BMS monitored by smart device Decent batts but better for less $ out there. I wont buy again...
