Hi Guys,
I Have to install my National Luna Dual batery charging system into my new 2012 Pajero GLX. (Took it out of my Pathfinder when i sold it)
I would appresiate if you guys can give me some pointers on where you installed your regulator and relay units on your Pajero's. Some photo's will be nice. Where did you route the electrical cables for the B-H plug?
Also i saw there are tapped brackets in the engine compartment next to the firewall behind the battery. Is this for the onstalation of a dual battery or compressor?
Is there a standard bracket you can fix there to mount a battery or compressor?
Mine is in the front, mounted on the firewall, and my cables run to the back under carpet to the storage box where the 7th seats fold into. In there is now a 130ah Deep cycle battery and a i installed two new fused plugs one to the left of the currently installed plug and one to the bottom of it. Works fine with just 0.4 volt loss from the front.
Do you my any chance have a photo of your setup?outbackjack wrote:Mine is in the front, mounted on the firewall, and my cables run to the back under carpet to the storage box where the 7th seats fold into.

How did you mount the battery? Bolt a battery tray though the steel floor?

how did you measure the 0.4? and what was your output at the alternator? I recall it being around 14.3V (not immediately after start, but after a few minutes / engine hot)... which after reducing it by 0.4 makes it 13.9 - not enough to charge a deep cycle fully.

I measured it at the 12v plug outlet and measured it against the old 12v plug, I will recheck it and let you know. I will also take some pictures and upload them. I also saw a fuse which will actually boost the voltage on your alternator here is the link http://www.ebay.com.au/itm/Dual-Battery ... 4abf7799aa
The arb shop ensured me that it would not be necessary but I still think of doing it just got to find where the fuse must go. Overall no trouble as yet with my system and most of the times I go on long trips so there is and should be plenty of time for the battery to charge up.

Your battery will charge, but won't reach full capacity... Say only 80ah of the 130...
It also reduces the life expectancy of the battery.

Here is just a few pictures of the dual battery system setup, note the battery is a dry cell completely sealed in order not to ommit any gases in car, also mounted on a steel tray which is bolted through the box sealed up with some silicon. Sorry for the dust but it is a pajero and used for pleasure so dust is an integral part of my adventures.
My next addition will be the solar panel on the roof aiding as a wind deflector for rooftop tent, as well as a charging source for the battery for days when the vehicle remain stationary while out bush.

- Solenoid & circuit breaker
- new 130 ah deep cycle battery
Attachments:
- new dedicated 12v plugs 20a fused
I checked the plugs and battery voltages as well as volts to main battery only, there is .10 v drop when the solenoid is activated so the volts available is 14.04 so all good, should charge up to spec.Gemaskerde Tuinvurk wrote:Your battery will charge, but won't reach full capacity...

Found this handy graph
So I inspected the voltage readings which was 12.75 in idle mode which according to the graph means nearly 100% charge I am happy with that. Hope you find it beneficial compliments of sidewinder.com.au
- battery volt vs. charge %
Outback, that graph is for reading the voltage to estimate the state of charge. In order to achieve that level of charge, you will need a higher potential difference from the charging source.
In taking the measurement "at rest" , make sure you've switched off the vehicle and left it for about an hour. The battery heats up when you charge it, giving an artificially higher voltage reading.
Something else to consider is also that deep cycles (most lead based /AGM types), don't like high amperage - around 10 to 20% of Ah rating is ideal. Your alternator puts out many muliples of that. Will you battery charge? Yes. Will it last more that 3-5 years? Unlikely, unless you don't use it much.
