    Great tool for diagnosing parasitic current draw from battery
    This is a great tool for diagnosing car electrical problems. Our car battery was draining after two days if it wasn’t driven. I hooked this to the battery and watched the battery voltage go to 14 V as car was driven—charging system good. Then I watched the battery voltage drop as it sat overnight, seeing a cyclical discharging of the battery. (See photos with my notes overlayed.) I finally found the problem—the Bluetooth receiver for the Digital Key system was turning on and off continuously while the car was off, drawing up to 1.2 A. This has a great App you can download for free that acquires data and displays it nicely. Best auto tool ever.

    Great product. I tried two other monitors for my Lithium 12v 100 ah trolling motor battery. I trusted neither one since it seemed to always show 100% after hours of use. This monitor recorded power/percentage drop while using and power increase while charging and alerted me when charged to 100%. This is simple to install, just two connectors to the battery. Range is really goid. Boat is in garage and it connects anywhere on the same level in the house. Love the built in alarms. Great price to have the ability to check the battery level on your phone. Getting second one for the Fish-finder battery.

    Reviewed in the United States on February 8, 2024
    Style: ModernVerified Purchase
    I have a Honda CR-V with a small battery and which is mainly used for very short trips. This results in a depleted battery after a few weeks. This monitor allows monitoring the battery voltage without opening the hood or even going into the garage, so that the battery can be charged when necessary. It also monitors the voltage when cranking, but I'm not sure how to interpret that yet. The bluetooth and app work well but it would have been nice if it kept a weeks or so history on the device and if it had an export ability for the data.

    Reviewed in the United States on March 9, 2019
    Verified Purchase
    It is important to know this battery monitor will only communicate with a Bluetooth device -- like an iPhone -- over a very short distance. Maybe a dozen feet. And said iPhone needs to have its Bluetooth turned on, which is a small but continuous power drain.

    My Quicklynks unit is problematic. It tends to underestimate the charge on the battery, complaining that it is almost out of charge when it still has plenty of cranking power. Also, it sometimes says the battery is still being charged after I've turned off the engine.

    I'm learning to take its reporting with a big grain of salt. I still think it has some value, but I'd be happier if it was more accurate, and had more transmission range.

    Before I bought this unit I had purchased another, similar device that was supposed to link up with my WiFi network, and do much the same in terms of monitoring the battery. Unfortunately that device also suffered from poor range. It could not link up to my WiFi system while sitting in my driveway, just outside my house. That, plus a difficult setup procedure, led me to return that unit for a refund.

    If I can find a better battery monitor -- one I can trust, has WiFi capability and decent range -- I'll probably replace the Quicklynks unit. For now, I'll leave it installed.

    Update March 27, 2019 -- Unit is no longer working at all. It has been reading "0% Charge" on the battery, when there is still plenty of power to crank and start the vehicle. I can no longer return it through Amazon -- I'm past the 30 day limit -- so I am trying to get the vendor to replace or refund it under warranty. But their phone number listed on the Amazon product page has been disconnected. I haven't given up yet, but I'm probably going to have to go through Amazon to get the vendor -- Quicklynks -- to respond.

    Short version -- don't buy.

    Sensible, bonne longueur de fil, enregistre bien. Attention aux fils : ne surtout pas les modifier (y compris la cosse aluminium) car ils sont double, plats et en aluminium, donc à priori fragiles s'ils sont mal manipulés. Sur diesel, déclenche sur les bougies de préchauffage et très peu sur le réel démarrage du moteur. Dommage. A placer du meilleur côté de la batterie pour conserver une transmission bluetooth max.

    5.0 out of 5 stars Great way to monitor a domestic battery in a campervan/motorhome
    Reviewed in the United Kingdom on January 27, 2021
    Style: ModernVerified Purchase
    A very simple and low cost way to monitor a battery use. Highly recommended.

    I have installed it in my campervan on the domestic battery. It gives me a plot of the voltage over the last 30 days whenever I connect my phone by bluetooth. From that it is easy to see the state of charge both when in storage over winter and in active use the rest of the year.

    I've used various amp counting battery monitors before on boats - but nothing as simple and cheap and easy to install as this. And sometimes simple is better.

    My van has a voltage gauge on the battery but this is both more accurate and gives me how the voltage has changed over the last few days. The iphone app works perfectly for this. I've had no problems with this app. It asks for permission to use bluetooth as it has to - so no what sure is meant by asking for "scary" permissions. It just does the job.
