My BMV 702 worked perfectly for about 3 years. Now it shows a voltage that is low by 7 volts. This measurement is verified by a multimeter, two solar charge controllers and the inverter. I've changed the inline fuse holders and inserted 1amp fuses. I've checked every connection for corrosion. I even recently replaced my entire battery bank with LifePo4. The BMV seems to accurately record amp hours in and out, but the voltage is just 7V low.
Here is a link to a power forum thread where I tried to get help with my problem: Power Forum
Please, I did check all of the suggested threads for answers. There is none.
