ANCEL Battery Monitor

I have been using this battery monitor and app to monitor my RV battery for about a year now. The monitor works great. The app installed easily and connected to the monitor device easily and the entire system works well. So well that I’d like to monitor my utility tractor’s battery too but I see no way of setting up a second monitor (or third, forth, etc.) without corrupting the RV battery data.

It would be amazing if we could calibrate voltage for devices out of normal range. Mine is .4 of a volt off . Simple update with the option for calibration would make the purchase that much better! Please consider!

So I bought this so it would give the battery life percentage when I wanted it. Beware it does not give nor send any notification at all on the battery life percentage nor notification of status.

Install the unit on my Tesla OEM battery, and immediately I could tell that this was a joke of a product. The fonts did not allow the messages to be displayed, the graphs were not accurate or legible and cannot update firmware using the app. Contacted support and ask they did was want to ask me more questions rather than offer simple answer to, is there newer firmware. The questions appear to be from ChatBot AI and the more I asked for support, the more they asked ridiculous questions that had nothing to do with the device. I would not recommend this at all since my confidence in the readings are very suspect.

ANCEL Battery Monitor is a great app to monitor your battery’s health. You need a physical hardware in conjunction with blue tooth. It allows you to see crank voltage and voltage over time at idle and charging. I would give this a 5-star if it allows e Perot of the data to PDF format especially trip data. I do hope the developers add this feature as future updates.

The app doesn’t support more than one car. So if you have more than one battery monitor it’ll just connect to the first one it sees. And there’s no telling which car it’s connected to since you can’t label them either.

Got the device on Amazon, hooked it up, installed this app and it just connects and works. I’m not sure what would happen if you had 2 monitoring devices but with 1 it amazing and simple.

It’s a great little unit to save you from calling AAA to jump your car because you didn’t know your battery was dead.

Had sent message through there app to inquire about not knowing if I had the latest version or not. Over the day, less than 24 hours a new app update came out and was very surprised as to how quick this help answer my issue I was having. I am gratefully appreciate of there fast help in resolving this. THANKS : )

I installed this on my RV batteries, two 12 volt in parallel, to monitor parasitic battery drain. I am absolutely amazed at the information that is charted and the ease of accessing the voltage over a 24hr period. I only use it to monitor voltage and for the price of this device, it’s outstanding! Also great for monitoring the smart charger. I have no problems getting into the app, granted you can’t get too far away. It’s mounted in the step well battery compartment, metal enclosure.
