Great battery and I like the Bluetooth app
Great battery, I really like that it's Bluetooth enabled and I can check on the batteries charge from my phone. I am using it in an RV to run my refrigerator while I am driving. I have installed the app that monitors the battery on an old phone which I wiped clean. I don't have a sim card in it and it is not connected to WiFi.

1235A Lithium Ion Battery Review
Batteries are operating as advertised. 100W solar panel charges them sufficiently. I'm using them with a Renogy 3000W Inverter on my bumper pull camper. I'll put them to the test this weekend and report back. The copper wire ends that are supplied are worthless. Purchase the proper fittings with that 2-4 G wire you use to join batteries. I didn't download Chinese App to monitor batteries. I'm using: Overkill Solar App. It's awesome. Most-importantly, get out and have FUN. PEACE from Santa Barbara, CA
