I purchased a BM2 battery monitor to hook up to my camper battery. I dry camp a lot and use a solar panel to keep the battery charged. I wanted something easy to use to check battery state. I am not interested in power in or power out of the battery. I just wanted to know if it was dead or not.
I bought one of the BM2 blue tooth battery monitors to try out. I have not hooked it up to my camper yet, but will this weekend.
In the mean time I hooked it up to my car, which it what it is meant for, to try it out. I am impressed with how it works and the information it provides. It gives a pretty good diagnostic of the car's charging system.
The fact that it will maintain a month's worth of data with out being near the phone is great. I do not get to my camper every weekend. In fact I have not been there in a month. Being able to see what happened when I was gone should be interesting.
I will put it on my camper this weekend and follow up after it has been on for a few weeks.
If you're a gadget nerd like I am check it out.
Not me. But shows how it works.
