X2Power Marine 4+

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.

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

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.
