Features:
This is a multi-function DC meter based on 2.4G datatransmission technology.
It can measure miscellaneous parameters such as voltage,current, power, and discharge capacity, watt-hour, time, and temperature.
It has over-current , under-voltage ,and limited and other functions.
The instrument can automatically identify the direction ofthe current, and the battery capacity can be monitored in real time.
The instrument uses TFT LCD display, display information iscomprehensive, user-friendly and better interaction.

I like the display, but that’s about it. I bought this a month ago and have noticed that it does not report accurate state of charge (SOC) and discharge current over time. I connected it to my LiFePo4 48V 16s battery pack with a Daly smart battery management system (BMS). The BMS reports extremely accurate SOC, so compared to that, the this device falls short. Also, it is difficult to tighten the lugs onto the bolts, so be aware that you will have to disassemble it to secure the lugs.

Product works as advertised. Only issue I had was the signal strength. I had to locates it father away from my battery than I wanted. I want to mount the display by the factory tank level panel. But the signal is not very strong, so I had to move the shunt closer.

Overall poor design. Cable access holes in the cover are not large enough. The cover cannot be put on after connecting the cables and the cables cannot be installed with the cover on. I have not tried it yet so I gave 2 stars assuming the unit works.
