12volt x 12volt battery chargers by RedArk, any good?

Hi Robert

Interesting spec sheet, i will have to compare to redark, I thought they were only maker!
from memory the spec of redark not as good as this ABR one?

thanks GN

Hi Ian
Fair points and i must admit i have not thought it through a lot, but uses may be
- charging a boat battery from a vehical running a fridge in boat while traveling.

- topping up the aux battery to get another days camping without having to run generator or vehical to charge aux.

- for those with a 3rd battery in a trailer / van whom have poor charge set ups.

- an ability to have a mobile + independant charge system that ciould be used in a number of vehicals / situations.

What do you think?

Research and exploit what you can do from the alternator fully as there are a lot of things that can do that can achieve what you want for less that the $1600 price range for the one you have mentioned and take into account that if one combine product failed you stop everything.
I cannot imagine that the unit could be mobile without difficulty to use from vehicle to vehicle and that would also add a lot more cost with installation due to its multiplicity function.
You should grow with something by experience instead of buying someone else expensive idea of what yopu should have and then finding out it is not all that its cracked up to be.
Efficiency is the target so as I stated at the start find the most cost effective way to exploit what you have already available.

So you sugestion would be?

I have a Rotronics independant charge system in one vehical and think its pretty good, want to do 2 other vehicals to dual battery systems and would like something that is simpler to install, and hopefully charges the aux quicker as well as being price competitive. Also being able to handle disimilar battry size / type like the rotronic independant charge does is important.

Go to Sterling-Power.com and look at the specs of the Alternator to battery charger and the battery to battery charger.
The alternator to battery charger goes from 80A input to 210A input and the battery to battery charger is currently 50A input.

The 80A and 130A alternator to battery charger can do all battery types with selectable settings and is a smaller footprint than the battery to battery charger.
Prices have come down due to the strength of the dollar against the pound and the prices are shown on our website that is still shown on this forum.
That will give you an idea but if you are interested please make contact by email as the price on the sirte is RR.

if you charged your battery with 50A you would kill the battery instantly
Ctek D250S $375 is good and Redarc gear is good. 2 good choices to look after your batteries and not wreck them. used Ctek on last trip and highly recommend

If you charged your battery with 50A with temperature compensation you would charge your battery quicker and would not kill the battery.

If you read my statement it clearly states input amps and that is what the units will accept and the resistance of the battery will limit what it will accept and with temperature compensation fitted this maximises what the battery can accept safely.

Understanding charging and batteries is done by major suppliers af chargers and alternators around the world and if it wasnt safe then no one would be making gear to do smart charging and there are millions of units now world wide.

Charles Sterling just happens to be a world leader in this field.

What a JOKE

"the poster is nothing more than a sniper and the post would have shot his credability to pieces. "??????????????????????????????????????????????????

I am just a simple farmer who like to learn and play with a few toys. I like to associate with decent people whom i have mutal respect with.

I realy dont understand the attack on my post but if it offends you then why reply??

Good LUCK and I do NOT need YOUR ADVICE, YOUR HELP, YOUR PRODUCT OR ANYTNTHING.

Good Bye

Er, GN, I think Ian was referring to Faulic_McVitte, not you.

Allan

Am i not "the poster"?????
GN

I in no way meant or intended to upset any fair dinkum person specifically you GN and the post in question was a vitriolic attack of me from faulic_mcvitte which the moderators deleted and I am not particularly worried about person attacks as I know there can be no basic substance to them.

If you did not see the post made then I can understand why you reacted as you did.

Remember if you ask a question you get answers so what you keep and what you dont is your business and your silence would be an accepted answer for anyone with a practical attitude.

Ian

GN,

It was directed to Faulic_McVitte and not you.


Ian,

All your response has done is inflame the matter. Please keep your responses On Topic.

Hello the hit and run merchant is here and what is so efficient about whacking out 20A?

What an over statement as 20A doesnt represent whacking efficiency but you definately appear to be whacking something.

How come you didnt say that Red Ark s are no good and you have replaced 10 of them already.
Ian

Can't see anything about solar charging or MPPT capability in any documentation I found for Ctek 250S.

Am I missing something?

Lex,

Ctek D250S

2nd page, it mentions caravan, solar / MPPT ..

I'd like to see it explained in a bit more detail, but it does look like an interesting bit of kit....

:)

Funny that it's not mentioned in the Ctek manual on the Ctek site.

"The statement most deep cycle batteries dont like much more than 20A" is a statement that is wrong and it depends on how you charge with what and what is the resistance of the battery.

You have generalised deep cycle batteries into one restrictive category and this can mislead people.

With todays communication you can talk to anyone anywhere in the world as easily as talking to someone in Australia and with the wide expanse of Australia it could be like talking to someone elsewhere in the world.

Technology today is rapidly changing and there is a company now in Brisbane representing a US firm in setting up charging stations for EV,s that can claim an 80% recharge in under 20Minutes and you cant do that with 20A.

The US parent have been conducting testing on various batteries and the Australian Company battery Energy Systems has been stated as have the best capacity longest life in a lead acid battery tested so far.

A 200AH battery energy battery could accept a 200A inrush charge in the first hour with temperature compensation.

....A 200AH battery energy battery could accept a 200A inrush charge in the first hour with temperature compensation....

I'd like to find out more about it, battery chemistry, internal resistance data, discharge graphs for various loads, peukert graphs etc.

Thanks for any links you might have for me.

Best regards, batterymeister

Ian, why would the battery manufactures stipulate different to what you are saying.

Out of the 5 brands of deep cycle battery's we sell (all leading brands), the manufacture recommends a charge rate usually between 15 to 30 amps depending on battery size.

As fair as I aware there is no ubute battery that is suited to the 4x4/RV market that can do everything well and except extremely high charge rates.

Can you please post the links so I can find out about this new technology.

Sure technology is changing fast but the technology is not usually available to the general public yet or is extremely expensive or unsuitable for 99.99% of applications.


"You have generalised deep cycle batteries into one restrictive category and this can mislead people. "

Please explain?

Soooo...that means any battery I can charge at what ever current I feel like?

Can you also fill me in on the Red Arc problems you are seeing.
