I've had no choice but to move on from NBN & its rotary dial phone sidekick because recently they were installing new copper phone lines in our area!

---

We ended up dumping the NBN at home and fixed wireless internet at the workshop and extended the data portion of the business mobile phone. Now we have much faster internet both at the workshop and at home and went from $75 for the workshop plus $55 for the NBN plus $60 for the two phones and now pay $63 for the 2 phones, unlimited calls and 60GB of data a mth that we will never use even half off.

The original NBN would have been worth joining, but the pitiful mess we have ended up with after political interests got involved is a complete waste of tax payer's $$ with only a few of the Telco's coming out on top.

I don't see any advertising

Jim

I have often wondered what the actual paying advertisers think of anyone on here posting the virtues of another system or equipment.

When I look at the top of this page I can see at least one advert relating to electrical that the Nomad Site would get paid to have them place their advert up there.

I have noted also that even if someone asks an opinion on any advertised product above, there is quite often several posts informing all that they think that a different product is better.
Maybe its an agreed condition that the advertisers above would have to tolerate but if I were advertising I would be very concerned how some people on here are permitted make unsupported comments or worse still just troll the topic.

I would spend my advertising budget a little bit more wisely if I were some of them up there which if happened would be a shame as they all are actually site sponsors that would go to contribute to the site operating costs.

Many other forums have a policy of no naming or shaming of products which I think is the fairer way to go.
Naming and shaming products on a public platform can actually attract legal action from detractors.

I note that whenever an electrical enquiry is raised then the anti Lithium brigade move into full swing.

I dont think it will ever change so I am content to be entertained.

Carry on gentlemen.

Our 100Ah battery can deliver what ever load you place on it, there is no upper limit. The limit is voltage drop and if/when the load is great enough to pull any cell voltage below 2.8v the battery will be disconnected. We generally use 300 amp mega fuses but we have fitted 500 amp mega fuses where big loads from multiple inverters in parallel are involved. Voltage drop starts at around 2.0CA or 200 amps per 100Ah advertised capacity but that voltage drop at the terminals will only be around 0.2v to 0.5v, most of the voltage drop still occurs through the cables, fuses and connections. I've watched a 300 amp ANL fuse slowly melt the centre plastic shell under a 320 amp load, this was the reason for switching to mega fuses with their better contact area etc. As long as you have the T1 lithium BMS system running at all times, we offer a 3yr renewable warranty. Bring the system back after 3 yr and we will clean all the cell terminals and links and retreat them with anti corrosion compound, memory charge and memory discharge clear the cells and do a capacity test at the manufacturers specified rate of 0.5CA (50 amps per 100Ah or discharged to 0%SOC over 2 hrs) and give you a graph of how the cell voltages faired during the test to verify the cells/battery is still at 100% capacity or what ever the capacity they return (every one so far has still been better than 100% even after 8 yrs full time service) We then offer another 3 yrs warranty and so one. The 3 yrs isn't one of those "you missed the 3 yr service so warranty is void" things, we have had some we haven't seen back here for 6 yrs or more, systems we fitted in the front yard back in Lake Illawarra, but they still come up after a service and we are happy to still offer the 3 yrs

Well actually, I didn't say that. Someone else wrote that infomercial

Not nice to take things out of context Tony, by not mentioning the post you copied was a reply to a hecklers post put you in the same basket. I don't want to paint you with that brush so it's up to you to show you weren't just adding a support post to a known antagonist but rather making your own statement.

Generally an infomercial contains a link to a website or phone number or some sort of contact address, without that could it just be viewed as an information post? That was the intention, an information post answering a question that was asked in what was supposed to be "in all sincerity" but all the posts since show the true intent of the question posted:

 

So EXACTLY how much is this 100Ah Lithium Terry, can we parallel them, what is its/their maximum discharge current, and what is the warrantee peiod?

No BS, no spin, just some facts will do.

 

How would you have answered the question Tony?

I try as much as possible to remain separate from my wife's business when it comes to giving advice on any forum. I'm not sure just what I should do when asked about an item I build and install as part of my input into my wife's business. I can't even claim I'm an employee because they get paid :lol: I don't get any money from any job that actually goes through the business but I guess at least it costs less out of the savings that remain in the bank so it could be construed I do get some benefit.
Kinda damned if I do and damned if I don't, so not sure how I should go about giving advice regarding a direct question about a product I'm involved with ....

About all I know about lithium batteries is How do you know that caravan camped beside you has lithium batteries ? Dont worry the owner will tell you within 5 minutes of meeting him ! . I enjoy reading about anything to do with batteries and 12 volt stuff because I really dont know a lot about it. I have a very simple setup in my tow vehicle and thats the way I like it. 2 120 ah agm batteries and a dcdc charger. No smart phone monitoring. Just a digital volt meter. My work ute is even simpler with a caterpillar battery out of a d8 in a cradle on the tray and a vsr with 2b&s cables. My caravan has (to my way of thinking) an overly complicated 12 volt setup, but the only thing I look at is the volt meter. I really enjoy reading what Terry has to say. One day when my caravan batteries die I will definitely look into lithium, but until then Im more than happy with what I have. So Terry at least one member here is interested in your posts and knowledge. Regards Pete

Thank you Pete, it could be worse, they could also be vegan :lol:

I know pretty much what camping fridge i am going to get, waeco cfx40.

 I'm running a cfx28, charging phones, camera, 4 Olight usb torches, charge AA batteries for toothbrushes & portable radio etc.

I would get the wiring right the first time as it is the most painful thing to replace if it is not heavy enough, & even more money!

My setup 4 x 26AH gel (space issues). 120 watt solar, DC-DC (will replace with smart version), MPPT 100/20.

If you can fit a larger battery all the better & the same for solar. Everything I have is 12volts. Cooking is with metho. Coffee beans we hand grind.

For $1500 you could put one of our 100Ah lithium batteries, a solar regulator and probably around 200w of folding portable panels. You could also add alternator charging to avoid having to drag the generator with you, maybe even sell it to fund the project.

This was the post I made back on the start of this thread and I stick by it. If the OP wants to design a system for putting the 4 x 50w folding panels on a roof rack or something, that is fine by me. Unfortunately our cell supplier just received his latest shipment from Winston batteries and with the falling AUD compared to the USD, the cost has gone up over 10%, so I'd be struggling to include the DC to DC charger in that quoted price now.

That leaves one wondering, if the cost price is still increasing, why are drop in battery suppliers discounting their remaining stock? Possibly to clear the shelves before shutting up shop?

I have no interest in attempting to compete with the lowest cost items around, the reputation one gets from selling something that simply fails up the track soon clouds over any possible short term gain.

This quote remains a true today as the day it was penned:

 Benjamin Franklin: The bitterness of poor quality remains long after the sweetness of a low price is forgotten.

On looking on the web I came across this
"More and more shonky sellers display battery capacity without the 20 hour suffix.
Capacity figures without the 20hr suffix are meaningless and in many cases this is done intentionally to con you into buying their product.

As you probably know, all batteries will return a lower capacity when you discharge them fast.
But it works both ways.
When discharging happens slower over a longer period of time, they offer MORE capacity.
So there needs to be a common denominator which according to Australian Standards is set at the 20 hour mark.
So for testing and capacity specification purposes you need to look at the 20hr figure or it will be like apples and oranges.
E.g. a 105Ah/20hr battery typically returns 125Ah when discharged very slowly, like 50 or 60 hours..
Unscrupulous sellers use this effect (google Peukert) to fudge capacity numbers to their advantage."

I studied batteries in 1958 so my knowledge of them is somewhat out of date.
But the above statement seems to indicates that a 105Ah/20hr battery will deliver the rated power as long as the load is under 5Amps, which is its rated discharge rate.
My fridge draws just under 5A, and then only intermittently.
I have a few led lighting bars and USB ports.
So I really have no need for anything other than an AGM battery.
I do have an inverter but only need it for charging up the electric tooth brush.
Computer, tablet and phone can be charged up via the USB sockets.

Hello all Merry xmas and a good new year now I am in the market to get new battery's for my van the battery's I had in there were Reco100ah and a Absorbed power 90ah now they were in there when I bought the van in 2014 Remco has a swelling problem so I have taken them both out now I have put 2x150 watt solar panels on the roof now I have read and tried to understand all what you guys are talking about but me mm mm I have looked at battery's 2x 120ah 20hr Kickass there called $558 and I think there called giant 130ah 20hr carnt remember the price my couple of questions are if I get 120ah or 130 its not going to hurt anything and dose anyone else have any suggestions on good brands that's aren't to dear

Cheers

Chris

I have the Kickass 120Ahr, 2 of. 4 year old no issues.

Nothing fancy  just 300watts of portable solar with the regulator on the panels, 5m 10mmsq extension lead. Works perfectly.

You won't hurt anything going from 90 to 120 or 150Ahr. They are providing more Capacity only.

Hi Chris 

I have used Aussie batteries and solar. Work OK and reasonable price. They will have some specials probably and free freight. Google them.

I was intrigued by the secret price for Lithium batteries and have been doing some research.
There seems to be a reluctance to advertise prices and I suspect that maybe some places are adjusting prices to either an estimate of the customer's affluence or to aid in on-selling various options.
However Jaycar to the rescue.
SB 2215, 12.8V 100AH LiFePO4 Lithium battery $799.00
MP 3741, MPPT Solar charge controller for Lithium or SLA batteries $199
MP 3746, WiFi Communication module for MP 3741 Solar charge controller 59.95

Total $1057.95

The MP 3746 is required to program the Solar charge controller. Need to enter the parameters from the battery spec. sheet.

I can see no reason why this is not a drop in replacement for an AGM battery system.
