They called and said they have a new replacement battery, But it’s the same one o had trouble with. I’m getting corporate involved & small claims court if needed. ### 1/5 — Wont connect to app *2023-08-06* Brand new fully charged . Wont connect ### 1/5 — Does not work *2023-07-25* Brand new 100 AH battery, will not connect to the app and it’s fully charged. ### 2/5 — App is glitching *2024-11-15* App doesn’t connect then it does and has a poor Bluetooth signal three feet away. The app shows brand new out of the box 48 percent charge on this battery. ### 3/5 — Useful when it works *2024-06-13* Bought two lithium iron phosphate 75ah batteries. Screenshots in the app listing show multiple batteries connected at once, my app only connects to one at a time. It switches the one to off and refreshes the search. Also it doesn’t consistently switch between batteries… i click on the first battery but the other battery details page loads intermittently. ### 4/5 — Great *2024-03-21* I’ve had no issues everything has worked great. My only gripe is you can’t not rename batteries. I really wish they would add a feature that lets you rename them. ### 4/5 — Almost perfect *2023-07-28* I’ve had no issues I’m using two of these in my camper set up. The only thing I wish they would add is the ability to name batteries. Should be a fairly easy thing to add. Add that and you’ll get your 5 stars. ### 5/5 — Great! *2023-08-15* I have an X2 Power 35ah Lithium battery that I use for my Riptide Pool vacuum. I’m a swimming pool tech who has to carry a battery box with my vacuum to and from the pools. Switched to lithium, mainly for the weight savings as comparable AGM batteries are almost 3x the weight. I’ve yet to have any connectivity issues over Bluetooth with this app. It’s great seeing the realtime state of charge and how many minutes of runtime I have left, in my case I start off with 90-100 minutes of runtime depending on what propeller I use. Only thing I could really wish for is an app for the Apple Watch so I can make quick glances at my battery status without pulling my phone out of my pocket. ### 5/5 — Blue tooth failure. *2023-06-03* Update, I was getting ready to take the battery back to Batteries + as they responded quickly to my complaint. After sitting fully charged for two days I opened my app and it started scanning this time and connected to the battery. Quick customer service but unknown why the initial failure happened. After charging the battery, using the 2X power supply. The app did not even attempt to communicate with the battery. Either the app is faulty or the blue tooth functionality of the battery is faulty --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
