Review: Battery for camping trailer - This is my first lithium battery, and I purchase it for the off-grid project in my camping trailer. I did some research before placing the order, and it seems this is the easiest set-up battery on the market. It's a well-made battery. The delivery was in time and the battery was in a good condition. The product is in a good quality. I cannot wait to start the project with my kids.
Review: Large capacity, small footprint, lots of features! - We’ve just completed our second season on the road with this battery, and its performance has been flawless. The on/off feature helps when we’re adding accessories and dealing with other wiring issues. The Bluetooth app provides all the necessary data on state of charge, temperature, cell health, etc. As stated in other reviews though, you need to be within a few feet of the battery to use it. The only negatives for us are the Anderson connection (larger guage wiring than we require) and lack of a mounting bracket built into the case. Other than that, highly recommended!

### ⭐ Renogy Smart Battery Bluetooth Doesn't Work
*by A***R on March 29, 2024*

Don't buy the Renogy Smart battery! They put the Bluetooth inside the metal battery case and it is unusable beyond six feet...without obstructions, and completely unusable inside my trailer from as close as 2 feet. Of course, they blamed me for installing the battery in a "metal" compartment which is in fact enclosed by non-metal materials. When testing the Renogy's BT signal with a BT signal app from an unobstructed 6 feet away, I could see my Garmin watch BT signal from inside the trailer....about 30 feet away, but had nothing from the Renogy Smart battery in plane sight. Their customer support recommended solution is for me to spend $200 on a remote moniter... How convenient to get more money from me to fix their BT design flaw. Avoid this product for its design flaws and the Renogy company for their failed customer service!
