Outer Limits 4x4 Board

i am running a dual batt setup and i feel it isnt really that good as i have the standard $40 solenoid(the chrome ones with the 4 prongs) what is a good one that manages my batteries and like knows when one battery is low so it converts it to charge that battery for a while,

i also dont have a lot of money so get me some prices on the sort of cheaper ones thanks,
also what brands and whos running them etc etc

thanks all

don't know if this is what your after:-

CAT no MB3670

Hi outback_pootrol and fullmetaljacket, a little care is needed if you want to use the isolator you have the link to.

This is a diode type isolator and unless your alternator is one that sensors the voltage at the battery or you can increase your voltage regulator’s voltage level, using a diode type isolator will mean you will never be able to properly and fully charge either of your batteries.

Diode type isolators cause up to a .7 volt voltage drop and this equates to only 13.5 volts at either battery if your alternator is putting out 14.2 volts, which is about the average voltage output.

Most automotive type batteries require at least 13.8 volts or they just wont charge properly, resulting in a shorter battery life.

Cheers.

I did a comparison of systems here - http://neuralfibre.com/paul/?p=37

Traxide came out the second most cost effective as they let you use 100% of the Aux and 50% of the primary.
The most cost effective was nothing and due care, but many ppl don't want to do the due care bit.
Spreadsheet is on the site.
