Antigravity Battery Tracker Bluetooth Monitor System BTR-2 for 12V Lead/Acid Vehicle Batteries, Test Voltage Cranking Charging

This monitor takes about 10 minutes to install. It gives you real time battery voltage, cranking voltage and a test of the charging system. Mine was flagging my battery for low cranking Volts, 9.1V on an electric hog parasitic battery drain vehicle ( 2018 Honda CRV ). I replaced the battery before it got cold out and I'm set.I checked the readings against my volt/ohm meter and a load tester .This little device is totally accurate.It beats getting stuck or having to pull out the jump box. $ well spent. I have 4. Two are on my cars one on my motorcycle the last on my tractor.Excellent device must have. No drama involved with app install on android device.

Provides a lot of information with good Bluetooth range. Good choice for the money.

So far it's been working. The app is easy to use, just like other Bluetooth devices you lose connection, outside I been able to get about 130 feet away and in my house it's about 30 feet, at night I can be on the opposite side of my house and pick it up.It can help you if you think you have a parasitic draw that's draining your battery, as it graphs out your voltage as it goes up or down and shows it for 30 days, just remember the first hour or two after you shut your vehicle off it starts to go to sleep, so wait about a hour or two to start watching for a parasitic draw.I would use this to do the testing for a parasitic but it will help you see what is going on with your batteryNow the bad, the terminal ends do not fit a 3/8 bolt. I emailed the company asking about cutting the ends off and that would void the warranty.The length of each wire should be longerIt's not accurate mine is off about .5 of a voltIt could have more features

A few thoughts on this battery monitor system with regards to using it on a motorcycle:- It has promise and is fairly easy to set-up. Be mindful of the size of the spade connectors on the device leads, they are likely larger than whatever it already on your motorbike's battery. Use a washer or slip this connector on the bottom of the connector stack.- The app needs some clean-up and interface improvements. You can actually set up and name multiple devices per iOS/Android app, but you have to navigate down a few menus to switch. This could easily be put right on the main app screen.- It would be awesome if this could also be expanded to monitor parasitic battery drain with some in-line sense device that could be installed on the battery terminal.Aside from that, I had to order this from Amazon twice in order to actually get the new-condition device that was advertised; the first one as visibly used and looked like it was a repackaged customer return. Garbage.

I bought my first antigravity battery monitor for my lithium battery on my fishing Kayak and it has been awesome. I bought another for my Arima boats auxiliary battery than runs my electric downriggers. It tells me precisely what all my different batteries levels are and I can even check all of my batteries voltage, usage and other things I cant remember from my phone while inside my house. These were a great addition to my kayak and boat giving me peace of mind knowing my batteries are fully charged and how long I can continue to fish and at what rate. Just download the app, connect 2 wires and your done.

Very useful, voltages and settings on point .. works great ..

Give current and past statue of my battery usage.

This works out great on my motorcycle. Plenty of info and I don't need to figure out where to put an additional voltage gauge which wouldn't provide as much info anyway. Just make sure to verify you are getting the right one. There is another version for lithium batteries

Installed this on the primary battery on my pontoon and it works great. Gives me all the information I need about the status of the battery. I highly recommend this product!

Pro: Easy to install. Will send u notification about battery Heath at any interven u set, without starting the bike.Con: The wiring could be longerOverall “It’s A Great product, at a good price point.
