How to use:
1. Push the black button for about 3s until it shows “1-U” and release it. Push it again for 1s it shows “2-b” and release it. Push it again for another 1s it shows “3-c” and release it. Push it again for another 1s it shows “4-d”.
2. When it shows “1-U”, push the black button for 3s then you can adjust the voltage admeasuring apparatus. Push it for a longer time, the voltage goes up. Then push it for another longer time, the voltage goes down. Do it again and again. To save and exit Automatically after the screen is twinkling.
3. When it shows “2-b”, you can change the type of battery.
12V: 1pc 12V Lead-acid battery
3.7V: 1pc 3.7V Lithium polymer battery
3.2V: 1pc 3.2V Lithium iron phosphate battery
1.2V: 1pc 1.2V NiMH battery
4.When it shows “3-c”, you can adjust the number of batteries.
Please refer to the following:

Here's how I figured mine out for anyone interested or confused. I have two 12.5V sealed lead acid batteries in parallel (12V system). The meter came configured for 12V & "2" batteries but showed "0%" and the voltage reading was off a bit. The correct settings? I confirmed it was set for 12V battery types. Then, I measured my fully charged battery bank with a quality gauge (it read "13.4V" fully charged) and I adjusted this meter to read the same. It still said "0%" though because my "2" batteries were PARALLEL. So, I set it to "1" battery and now it read the correct "100%". If the bank was wired in SERIES, the meter would be set to "12" volt batteries, "2" batteries in series, adjusted to roughly "25V" when fully charged.
I hope this helps anyone who might be confused by this otherwise good meter that came without instructions. I like that I can change my bank in the future if I decide to reconfigure my system. Good meter.
The good things about this is that it's relatively easy to program when you figure it out and it looks really nice to have this big bright battery meter instead of just a voltmeter. I definitely reccomend the product despite the voltage adjustment thing but to fix that I set it to % only mode. Great product and easy to use
Most annoying is that the UI to configure this module simply sucks, and there is no manual to explain it. Luckily, other reviews did a good job explaining it. You may want to use an adjustable lab supply to verify you have configured it correctly.
Since I did not want the unit to be powered all the time draining several mA's from the batterys, I added a pushbutton switch to activate it on demand. However the unit takes a few moments to "boot up" it isn't instant, and if you set it to flip between % and V, then it takes 5 seconds to get to %.
And lastly, it should be mentioned that this cannot by it's nature measure energy in or out, or current at all. Monitoring battery voltage does not tell you a whole lot about how much battery is left, and if the V -> % mapping is linear, than it isn't taking into account any discharge characteristic curves which just means it's very inaccurate.
All that said, I still really like it!
I had the 2-b set to 12 thinking that would change it from 24 volt factory setting to the 12v i wanted.
Kept showing battery dead? After getting multi meter out proving to myself battery was charged.
I figured out you need to be sure to make it to 3-c and set it to one battery. It was set 2 12 volt batteries in series = the 24volt default setting.
