BM Pro Wireless Battery Monitoring

I came across this today.

It's a battery monitor that works through your smart phone. It has a shunt like you would expect, but it also has bluetooth connectivity. It appears to be extremely easy to install. All you do is connect it to the battery, and pair it to your phone. No wires to run to a monitor.

Does anyone have one, have experience with one or even seen one? I'm wondering how it compares to the Tri Metric.

The ease of installation is compelling.

I haven't heard of those before but it looks very interesting. I'd be curious to hear about any real life experiences with this device.

I did a quick look at the information in the link. I have a Tri Metric system in my FC 20'. Some quick impressions:

It probably is not as versatile as the Tri Metric in that it does not have all of the various possible readouts and settings the TM has. On the other hand, many will never use the capability of the TM, and sometimes the TM is kind of a pain to figure out and use.

The cost is considerably higher than the TM.

It most likely would be easier to install on a simple installation than the TM, but if you have two large negative cables as I have (one for the inverter, one for the coach) it might be more difficult to install.

The idle current of 10 mA, although not high would, over time, run the batteries down, so, it needs to be disconnected for long term storage. The TM also has that same problem, just one more reason I recommend total disconnection of the batteries when in storage. I think this one would be easier to forget, not sure.

If you are comfortable using your smart phone for everything, I guess that reading the battery capacity etc is ok, but I like a dedicated readout. I am old school, I admit.

Has anyone installed a BM Pro BatteryCheck? I'm curious to know how you like it, how long it's been installed and any related comments. A friend is considering having one installed and I'd like to know more about the product and it's operation.

I recently installed a Tri Metric monitor and found it to be a wonderful tool. For those who want wireless (i.e. Bluetooth) operation the BatteryCheck product may be just the ticket.

I found the same wireless unit recently (Jan 2016) and am considering buying it. Did you end up getting one and if so do you like it?
