power queen500A Battery Monitor with Shunt | Programmable Alarm | 8V-120V Voltage Range | LCD Display | 20ft Shielded Wire | Compatible with 12V Lithium, LiFePO4, Gel, Flooded Batteries

Does what it's supposed to do: gives information about your batteries. I have it running on a 24v 200ah 2p2s battery array and it gives helpful information as long as you set it up right. Takes a little effort to install, but is worth it.I like the Power Queen company as they seem to have quality products and good support.

I feel Power Queen has a great product and at a excellent price point! I use several different types of Power Queen products on YT. This battery monitor is accurate and usually lower price than the competitors. It holds same features and functionality. Easy to set up and accurately detects the smallest of current flow. Can handle large current easily up to rating as well. Highly recommend!

Works great

Pretty good tool once you read the manual and learn how to propery use it. No complaints here.

Easy to install, Instructions are very clear. Screen was perfect size and easy to see. For me it was pulling 0.00w with backlight off, and for the 8-10 seconds backlight is on after you hit the button, it drew 0.08w. Quality product in my opinion and gives exactly the info I need at a glance of the screen. Highly recommended and would buy again.

Great product and consistently excellent customer service. Much better than my experience with Ecoflow!

Easy to install and plenty of cord from shunt to monitor

It worked fine for 6 months now it wont register that there are 200 ah of battery and is stuck on 100 ah. So it tells me I have 50% with 2- 100ah batteries. The batteries are both full and connected correctly. Now I cant monitor my solar panels. Piece of junk.
