## Questions & Answers

**Q: Can you leave it attached to the battery all the time while using the lithium battery for a trolling motor?**
A: Yes.  Leave it connected.  It uses very low voltage.  Use the mobile app to monitor and see how the battery voltage drops over a period of time.

**Q: Will this monitor two batteries in parallels by hooking up to one?**
A: Wouldn’t see why not, since when wired in parallel it becomes one battery.

**Q: Why does the battery percentage fluctuate so much. Drops to below 60% when moving in my kayak and comes back to 90% once I stop.**
A: Has to do with lithium ion battering, they don't read like acid

**Q: How much power does it draw?**
A: Hi Tim, the Battery Tracker draws 1mAh. Thank you and please feel free to visit us at antigravitybatteries.com if there's anything else we can help you with.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Exactly what I needed and works better than I thought.
*by G***. on October 6, 2023*

No one who owns a Gravity Battery for their hobby vehicles and etc. should be without this product.Easy to use, and can instantly tell you your battery's condition so you'll know if it is good to go, or if you need to be charging it.Cannot say enough good things about this. It is a must own.

### ⭐⭐⭐⭐⭐ Perfect accessory to go with your battery.
*by J***N on December 21, 2023*

I needed a security camera in a remote corner of my yard and solar power was my best and cheapest option. The camera would occasionally drop off the network and I thought I had power issues, but once I installed this battery monitor on the battery, it was obvious it was not the battery, but something else. I was completely impressed with the high resolution graphing options, one shows the instantaneous real time voltage, and the other shows the 24 hour voltage, so I can easily see when the battery is getting a good charge (5 hours a day in that location), and for how long, and the discharge when the sun isn't shining. It also shows the charge level of the battery at any given time. The battery and the monitor is in a metal weather enclosure which one would think would block the Bluetooth signal, but I receive the battery status from the monitor easily when I am within 50 feet of the box. Would like to see a version with the option to add an external antenna just in case I needed more range.I plan to buy more of these units and put them on my other battery projects for piece of mind, and to make sure I don't ruin any batteries by not keeping them properly charged when I store them. I highly recommend this accessory for your batteries to help give you that extra piece of mind.

### ⭐⭐⭐⭐⭐ Used on tracker lithium battery on kayak
*by S***L on January 13, 2023*

I have this on my 100ah tracker lithium battery, which is on my Old Town autopilot kayak. Until now I had no way of telling what the level of my battery was. The autopilot has a meter, but it's not made for lithium batteries. The app is very easy to use and understand. The battery tracker is easy to install. I'm glad that I got this.
