VERY IMPORTANT! When programming this meter for a single 36v 100ah LifePo4 golf cart battery be SURE TO CHECK THE "STRINGS" of your battery or the % (0-100%) part of the meter will not be accurate. I have a OGRPHY 36v 100ah battery and I finally figured out it has 12 "Strings" inside its design. I searched everywhere and finally found it in the battery app purely by accident.In the programming you have 6 sections 1-6. 1 & 3 are the primary sections used to set up the battery info.Section 1 is to tell the meter what kind of battery, and how many Strings the battery has. In my case this is how the section 1 needed to read. 1 F12. Default on this unit in section 1 is 1 P03, so you need to change it to F (for LifePo4) & 12 (strings).You will need to find out how many strings your battery is designed with...maybe 12 is industry standard, but I'm new to these golf cart batteries.Section 3 is where you tell the meter on the left and right of the screen how much voltage is getting close to dead/recharge and how much full would be. In my case I used 35.0v on the left side for dead/recharge and 40.0v on the right for fully charged. (get specs from manufacturer)The % side of the meter is now exactly identical to the battery app readings.Its really much easier than it appears to be in my review, just sit down, relax and take your time going through the sections. good luck its a great little meter.

Easy to connect and use. We plan to neaten up our install and attach it with the peel and stick Velcro.

This is my second one of these. The first I broke while trying to move it. The wires on it are only 24 gauge, very difficult to manipulate when they're like a human hair. To make them more durable I soldered the cut ends. The voltage didn't seem to agree with my solar charge controller. The second one replaces the ultra cheapo factory battery monitor that was built for lead acid batteries. Hopefully since this can be set for a Lithium it will be more accurate

After living with minimalist LED lights in my camper trailer I decided to upgrade to a digital readout to show the house battery status. One of the features of this unit was the white back-lite display. It is a nice brightness level and is easy to switch on and off. (The blue LED's used in the standard control panel are annoyingly bright at night so that made a black fabric roll to cover them at night.) When it arrived I was pleasantly surprised with the size of the unit. It is large enough display making it easy to ready but its small makes it easy to find a place to install it pretty much anywhere.I made a cardboard template of the display housing in order to mark out the mounting hole in the side of the cabinet...just below the main control panel. Using a oscillating saw I carefully cut along most of the lines then used a coping saw blade to cut the corners and a file to fine tune the hole. The front flange frame is narrow so you have to be careful not to cut the hole too large. Start small and tweak to fit. My cupboard side board is 3/4-inch thick making me concerned that the display would not grip and stay in place. However, it went in smoothly and hold fast.The wire pigtail (connector on one end and raw wire on the other end) is nice because I was able to easily find and connect to a constant 12-volts, positive and ground....then plug it into the back of the display. Installing it next to the original control panel certainly made this job very easy.It took me a few minutes to understand the sequence of button pushes to cycle through the menus and make the selection for my application. It likely took longer because I push the button too fast and race past where I should have stopped.Once I had the unit set up just how I liked it....I stepped back and admired how nice it looked in the cabinet side. It looked like it came with the camper / trailer. The LED display is easy to read and understand. Just the right amount of information to let me know my battery status. Using a digital multi-meter I compared the voltage at the battery to the voltage displayed at the SUPNOVA unit. They were exactly the same.Yes, I recommend the SUPNOVA battery status display. Actually my son is getting one for his camper.

Bought this to monitor a 24v solar power reserve battery bank.Pros: cheap; bright displayCons: everything elseIncluded wires are way too short to be useful for monitoring anything other than a battery sitting right next to it.Whatever lightweight gauge they used (24awg?) plan on using lots of electrical tape to keep it bound to your extension wires unless you can find really small gauge splints.Custom settings seem to save between connections, but whatever settings you chose don’t show up again when you revisit the settings again so you better have written them down.Settings screens aren’t intuitive. You better have the manual ready. Good luck finding it on Google.But most frustrating of all is menu 5. Apparently this is a calibration menu, but if you accidentally hit enter instead of the menu button while connected to a battery source that isn’t EXACTLY 30v supply then your monitor is now bricked. Why do they even have that setting????!!! And there is no factory reset mechanism.

Don't waste your money flimsy wires does not respond to on/off or anything else after 2 days

El producto es bueno con relación al precio ,en mi caso lo utilize para un carrito de golf la instalación fue fácil no tuve ningún problema,para configurarlo el manual solo viene en inglés pero con un traductor es más que suficiente si tienes alguna duda puedes buscar en Youtube medidores marca supnova el menú es exactamente el mismo,por el momento solo queda ver cuánto dura. Nota le puse 4 estrellas porque los cables que salen del medidor son muy delgados aunque no afecta la instalación les falta mejorar eso.

Came with no Instructions

When programmed correctly it works as intended when used with lifepo4 batteries. Voltage accuracy is within 0.1v of nominal multimeter readings. The instructions however are not very well translated to english. There are incorrect words used and grammatical mistakes. If you are not adept to taking on challenges and are not technically inclined you may want to look for a more user friendly product. See the negative reviews below for more details.Note: You will need to know your battery type and min/max nominal voltage values to program this item for accurate battery percentage results to be displayed.
