Review on ๐ LNEX Portable Battery Monitor with Shunt: 500A Car Battery Monitor for RV Battery, with Programmable Alarm & 26ft Wire by Don Devine
I am impressed! in Tools for diagnostics, testing and measurement
I am an electrical engineer and generally find such devices very disappointing. You usually have to spend a lot more to get something reliable and accurate enough to meet your own specifications. This battery monitor lives up to its advertised specifications. I have access to some lab power supplies, meters and loads. With these tools, I was able to verify that this battery monitor actually meets the 1% tolerance specification; hardly, but it qualifies. I haven't tested the temperature drift yet, but so far it seems to be very stable.
