Battery bug installation on two banks?

I have a house battery and a starter battery, with a switch.

I also have a battery bug which was never installed by the PO of my boat.

Can I hook this up to my switch, so that it will read whichever battery bank it is switched to, or will read both when the banks are used together?

My friend thinks it might have to be hooked up directly to one of the batteries, because it must constantly monitor the battery in order to be accurate, so it would get confused and be innacurate if I switched the banks. Is that true?

Re: Battery bug installation on two banks?

What type of batteries are we talking about. Are they the same type, size. Is the bug programable. It appears that the two leads on the battery bug go to the two poles of one battery. Is your battery switch isolating the batteries and then has a combine feature? These are rather inexpensive and not very reliable from what I have heard
from others.

Re: Battery bug installation on two banks?

Peter- is designed to be attached to an SLI battery and left connected to it. Switching between batteries really should confuse the heck out of it. I can see why it wouldn't sell very well, since it requires presumably a car owner to OPEN THE HOOD every time they want to read it. On a boat...since you've already got it, I would install it on the one battery and leave it there. House if you want to use it as a monitor, otherwise leave it on the starting battery and just use the house battery as you need to, charging it whenever you can to try to minimize the charge cycle depth.
