12v - 84v Digital Battery Level Voltage Monitor ALTERNATOR Meter Gauge LAMP Indicator Status

What I expected for the price, would mount neatly in a panel. Just put battery clips on and used it to monitor 12v battery on charge. Don't know how it measured level of capacity of charge, think its just a percentage of the max voltage it measured last so if your battery charged at 13.8v and was 12v off charge it would say 87%.

The monitor was used to check the level of batteries in a portable test rig, very well made and good price,if this works ok then I will be getting another one.

Does the job perfectly. Didn't expect it to work or last but for the price it has been very good value

Bought for Ebike. Does what it’s suppose to do 100% reliableTT

A great addition to any 12V system, packaged well and delivered on time, now installed on a miniature locomotive where I can keep an eye on the battery usage

Perfect, really easy way to quickly check the state of my leisure battery, bought another now.

I bought this to monitor the voltage in my car battery when waiting for the wife so I will not be looking for a jump start 😂😂😂

Just what I needed to monitor my scooter batteries.
