200A Battery Monitor with Hall Sensor for AGM and Lithium (LiFePO4) Batteries

I liked all the options that were listed for this monitor but after I installed it, it doesn't seem to be as useful as I had hoped for, in my case anyway. It works fine although I had to manually set it up since I didn't want to drain my battery to zero in order for it to sync up correctly as it states. Didn't think that was a great way to start. I had a 2 AWG cable with a heavy duty lug that was attached to my battery so thats what was going through the sensor and it turns out the sense is the same size so it would not fit through it. I was able to shave a little bit of the copper lug on both sides in order to squeeze it through. If I had not terminated my battery cable already then it would have been fine, until I remove it. I also don't really care for the mounting option which is basically mounting it in a pre-existing rectangle of the same size and forced in place, which I can't see ever being the case. This isn't a standard thing so who has a hole like this, plus a DIY type never would anyway. I have to cut it into my wood wall but its really not the right way to mount this as the slightest miss in cutting it in will make it unusable as a wall mount option. Very, very little room for error. I would have preferred a trim plate that could allow at least a little room for error to be included. I also think it should be just a little bit larger so you can see and read it easier.

Overall its decent but it took me a while to get it to work right and I still do not have it mounted as I am contemplating how best to do that. This being a retail or DIY type of situation for most of us I assume, it would be better to figure how to mount in a wooden wall type environment. Something that is round, say 2.5" would allow a hole saw to be used, regardless of thickness, and then a 2.5" washer at the rear to hold it in place. Maybe allowing for up to 3/4' thickness.

The shipment took longer than expected. The packaging arrived without problems, it is adequate, but the instructions for use are confusing. Once installed I can give more information about it.

This is a real must have item I am getting much more use of my off grid system and saving more with this it way pays for itself and gives much more real time info than other types of devices

Is this compatible with two 150ah batteries?

Easy to install, easily readable screen.
