Auxiliary battery

[Doctari]

Unfortunately, I know little about electronics. So, what comes with the auxiliary battery, and why would I want an auxiliary battery? Thanks in advance for your help.

Kept closed in a climate controlled lab at 25C. It'd be at least double that in the field in summer.

In your field. Which fortunately isn't mine!

Did he specify anything? Is it just the capacity?

I use 1.1amps an hour in the warm West Australian conditions with my 52l Bushman

Well I won’t argue the actual numbers because I don’t have a proof point. However I do know that in my previous vehicle with an an Optima yellow top deep cycle battery well under 105Ah I could run my Bushman for about 2 days in hot temperatures fairly easily. I really don’t expect much more than that from any dual battery system without running the car or topping up with solar. Depends of course what else you are running but I don’t run an inverter or induction hotplates or appliances etc when I am camping. I do sometimes run some low draw led lights but usually they run from my camper battery

Never forget I'm in Tasmania. Snow to surf in a couple of hours.

Does the IG come with an Anderson plug somewhere externally?

I don’t tow, but really liked having this on the old 110 with my dual battery setup as it allowed me to make a long extension lead and run it to tents etc., and also this is where I would connect a battery charger too when parked up in the garage for a while.

No Anderson plugs.... it will need to be a DIY mod.

Ahh, shame. Thanks

Depending in your spec it has a NATO style plug on the back and I have made up an adapter to Anderson, however apparently it isn’t live all the time. Rumours that a software change may fix but otherwise may need to bypass the relay to make it permanently live.

Thanks. Trialmaster, so I believe that’s all the internal electrical toys/ options ticked? Not sure what a NATO plug is but not fussy about shape, only timing/flavour of the electricity supplied. Will keep an eye out for mods which enable

That is one.. certified for 12V or 24v and up to 1000A. Grenadier specified afaik (not verified). 12V 400A

1000A is nonsense, maybe in the millisecond range. Seriously maximum 150A continuous or 300-400A short load.

Agree. Just look for the Norm VG 96917. There you find the spec. 30s 300A. Continues 135A.

Jump start cableT hank you .. the 1000A were on the cable 6 mins 24V just found the source.. see link.

The rear NATO socket is fused with a 350 amp fuse located in the 5 way Littel fuse box.

That's a different NATO plug, you picked the wrong one.

That is the purpose if a forum. Thank you. There is much information out there. Now I know there is not just "the one and only NATO Plug" but variants.

So in theory you could charge both vehicle batteries via this?

 

[MarkH]

Lead acid batteries of course have a cycle life depending on how deeply discharged they are. You often read caravaners saying 'I get 3 - 4 days no problem' but the batteries are being discharged to 10.5-11.0V. If regularly taken below 12.2V (50%) you reduce cycle life by about two thirds and you're replacing batteries every few years. Optimal cycle life is staying above 70% state of charge but typically not practical so 50% is a good compromise. A good system should be designed around that.
