Best inexpensive battery management solution

Hi all,
I have an FZJ80 - so a single battery - and I want to fit a second (combined deep cycle/starter) act as an emergency backup in some applications and to power accessories in others. I've already relocated the washer bottle and have an offside battery tray on its way from Julian. I also have a National Luna dual battery monitor fitted in the car and I'm about to order a new Exide Maxxima.
So the missing bit of the puzzle in a dual battery solenoid of some sort.
I don't plan to do any winching, I'm just looking for a simple system that I can use to
(a) isolate the 2nd battery on starting so I don't run them both down together (and also to run the 2nd battery down for accessories)
(b) combine batteries in parallel for regular charging
(c) switch in the second battery if the first one is run down for starting.
If it was possible to control this from the cab, all the better.
I've seen many battery management systems but the are ofter very expensive and look quite complicated.
Does anyone have a suggestion for a cost effective and robust system for the above?
thanks :)

Hello Andy,
This is my first post to the list (been reading for a while though).
There is a seller on ebay, Insideout4x4 who has got a couple of T-Max 180
amp, dual Battery/Split charge systems for sale. =A384.99
This is the item number: 290393065678
I've bought from this seller before with no problems.
regards,
Brett

I have a National Luna split battery system. It uses a lot of power when the car is not running. If the car has not moved for a week the battery is flat. Do you have the same experience with the T-Max?

I know there is a Bosch selenoid you can get that does the same.

Brett (and other people who responded to the post),
Thanks for this - the T-Max system looks like it will fit my (modest) needs just fine, so I'm order to order one!
Much appreciated,
Andy :)

Hi Karel,

I've got an HDJ80 with factory fitted twin batteries so no aftermarket split
charge fitted. I've no experience of the TmaX system, the one I posted just
looked reasonably priced compared to others.

I bought a 200 amp solenoid and intelligent splitter off flea-bay - it does
the job perfectly. The 3rd (in my case) battery only starts to charge after
the main battery comes up to charge spec - 13 volts or something).
Otherwise it stays isolated from the other 2 batteries, so overnight use for
accessories doesn't use the main power at all. However, if you want to be
able to introduce the second battery as a backup starter / emergency
battery, you're better off going for a marine switch that gives you
'battery1 - off - battery2 - both' functionality. You can get them
from marine stores online quite cheap. Also a nice extra theft deterrent,
if needed. I made up the entire split charge system - haven't put in the
monitor as yet (and I've heard horror stories of NL ones draining
batteries.....? Maybe just the battery mgmt system though?)
