About this app

The KH-F series volt-ampere meter is a new type of coulomb counter that can measure various physical parameters such as voltage, current, power, charge and discharge capacity, watt-hours, time, etc. It can also set parameters to realize multiple protection functions such as over voltage protection, under voltage protection, over current protection, overpower protection, over temperature protection and time limit protection.The meter can automatically identify the direction of the current, and can monitor the battery capacity in real time and display the measured data in use color LCD screen. The VAG series voltage and current meters add voltage and current curve display and export functions on the basis of the original functions. At the same time, the mobile phone APP and host computer can be used to control, and the firmware can also be updated and upgraded in real time.

Ratings and reviews

This app works pretty good and has great information and a good UI. It has some issues. 1. It seems to always report 100% charge regardless, and changing the maximum voltage doesn't change it. 2. The calibration setting isn't intuitive and when you find it it's only whole numbers of a percentage, 99%, 100%, etc. This isn't enough resolution to finally tune 4 digits to calibration. 3. If it does not record total Watts of charge or discharge. 4. If the chart doesn't show trends easily.

Very useful app. Would be more useful if there were adequate documentation. REMARKABLE number of ways to modify the measurement environment, scale current and voltage displays. Probably more sophisticated than most users would want. The size of a phone screen makes things a little awkward at times (e.g. for setting scales). It would benefit from having colours of graphs tied to colour of the appropriate axes somehow. Certainly complements the display panel that forms the front of the device.

App has notifications blocked and the option to allow them is grayed out. It freezes frequently and you need to force it closed and restart, and lastly 80% of the time it says "Connected" but fails to load any data and immediately disconnects saying "Disconnected, try again". Useful when it works but very unreliable and annoying.
