Battery monitors - best way to monitor battery status?

[Rob]

Where are you going to get 22 volts from ?

According to this PDF it is 12.8 to 22V input

For interest, I have 2 of the blue LCD monitors and they read within 0.01 volts of my multi meter when measuring voltage on my 3 new Numax CXV24's. 1 LCD measuring the 2 starter batteries and 1 measuring the third / leisure battery. They're 1000amp cold crank, 86amp hours

I get 12.86 - 13.22 depending on when I measure..

You'll probably find the 12.86 drops within a few weeks as they settle in. When did you fit them?

Hi John
Fitted the day before lincomb and probably started the car up 10 times since then.. I'll keep an eye on them (and fitting them in to a hobby box this weekend so they'll be permanently accessible)
Thanks for the tip..
