Bigger hyperion

[Burgerman]

Anyone looking for a Hyperion charger in the near future should wait until november.

http://hyperion-world.com/products/prod ... S1420iNET3

This has double the output power of the ones I use (so they are for sale!) and will do all the same good stuff as the original.

See http://www.wheelchairdriver.com/hyperion.htm

And around a month later a DUAL version will be available with 2 outputs that can do 1000 watts! I will be getting a couple of each... The old one was good this one is better!

You do know you're probably going to burn for ever and ever and ever and ever, for making us all want stuff we probably shouldn't afford, right ?

Thanks for the update though. It seems to be taking for ever to actually appear

[TwoTeasChris]

How much do you want for one of your old ones? And a suitable PSU.
Er, I assume that it doesn't have to be plugged into a PC to be used?

edit: I mean to be used fully programmable. Obviously no feed back/data.

[Burgerman]

I have 3. All 250 watt 20 amp max. That means it can do 10 amps into a fairly discharged 24v battery in your car or at home from a power supply.

Or 20 amps into a 12v battery or pair of batteries. Better to choose 18 amps or 9 amps though on a PC to get a text book charge curve!

No they dont have to be connected to your laptop, but once you do theres no going back! Its addictive to watch and see exactly whats happening. And to test batteries every few months...

One unused but opened. One used but unmarked. One used for a year but its almost impossible to tell. All have latest firmware and will need leads making up to suit your usage.

Sensible offers considered but I love them so much I may keep them!

[TwoTeasChris]

At the moment I just want to charge my wife's chair with its AGMs properly, 2 x 12v as per your lates t method. But it will rarely be parked near a PC.
Plug it in, press some buttons, wake up to efficiently charged batts. (Near text book.)
So I assume 'suitable leads' means a couple of andersons?
Two sites show them new at £115. How much for the year-old one with a PSU? You can't keep them all.

I use this as power supply heres one cheap!

OR buy now http://cgi.ebay.co.uk/Auto-Cooling-DC-2 ... 5d2b25e5b4

Because I am keeping the power supply!

I will sell the hyperions as soon as my new ones arrive!

[TwoTeasChris]

Are these PSUs good for the new hyperions? (Does the new one have a power supply built in or am I thinking of another one you mentioned?)

[Burgerman]

There are several new ones.

The newest one out in november needs a 550 watt power supply at 24v which is very hard to find. I just bought one... It will work though.

But its better to buy a 20 amp 24v version of the one I linked to above. Or you wont be able to use full power. They are also on ebay at twice the price nearly... http://cgi.ebay.co.uk/DC-Power-Reyed-48 ... 27a99a28b1

http://cgi.ebay.co.uk/480W-24V-20A-Regu ... 2c5795abdc cheaper

Then soon after a dual version is out! It needs a 24v 1000 watt supply! Or two 12v 20A power supplies as above in series... Or a pair of old powerchair batteries and small charger. Things get out of hand if you get too carried away...

Or you could buy one of these as I just have! http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... SA:GB:1123 40 amps at 30v adjustable...

How safe - water-resistance-wise - are Hyperions?

[Burgerman]

Define safe? They are 24v so you couldnt get a shock if you took a bath with one while charging. But they are logic controlled so they would not work very well! Splash and rain proof, not a problem.

Safe as in robust - how do they handle vibration and knocks, are they quite tough? -they look rather flimsy and delicate.

[Burgerman]

They are strong as in you can bounce them. Unlike our normal metal cased chargers. Because the heavy components that break free or damage circuit boards like transformers etc are not in the charger. They are designed portable and robust to take to your flying field and drop and stand on. And electrically they are fool proof. They are used by thousands of dummies all over the world that short them out and mis connect them. Short and reverse polarity etc cant hurt them. A shower wont hurt either but they are not waterproof!

Thanks Burgerman.

That is exactly what I wanted to know - there is a bitter irony to the fact that these Hyperions reach the market via glorified toy shops!

[Only kidding - but not that much.]

If you wanted to get the most out of these Hyperions as big-battery chargers, what is the minimum size of transformer that you could get ?
In other words, is there a pocket power supply unit, like the one I use for my computer-speakers, which just looks like a bulky 3-point plug - or is that asking for too much?

[Burgerman]

Full power out requires full power in. A standard wheelchair charger is self contained. But it onnly does one trick and usually not that well. And is about 200 to 290 watts.

A 300 watt power supply is small. A 600 watt one is big. A 1000 watt one is about 4x as big as your standard travel wheelchair charger.

Of course the hyperion can run from any power supply. Car battery or car. No supply needed! You have a 100 amp supply already!
Or a small pocket supply like your laptop one could be used. In which case you tell the hyperion what max amps the input is allowed to take and it will work fine. At a lower power level.

£41.18. Get em while the're hot.

[Stewpot]

Blimey!!!

I had no idea that you needed all this equipment to charge the batteries.

Looks very clever though... http://www.youtube.com/watch?v=-ox3EpzvsJ8

[TwoTeasChris]

Have you got your new Hyperions yet John?

[Burgerman]

Yep. The 1420 is on my desk! Cool too. But having PC problems at the moment and building a new one...

[TwoTeasChris]

Are your old ones for sale yet John?

[Burgerman]

One bought by a freind. One has usb connection issues. Yes it was my own fault! Dont ask... But if you dont want to connect it to a computer then yes it too is for sale. I use that one in my van for charging helis and planes mostly. Looks good and works great. But I am waiting for the new dual 1000 watt one... Basically a pair of 1420s in one package.

[TwoTeasChris]

... But if you dont want to connect it to a computer then yes it too is for sale...

How much?

[Burgerman]

Offers? Including carriage?

[TwoTeasChris]

Can the 1420i do 40a @ 12v?

[Burgerman]

No. Max 20amps. But it can do 20 amps at 24v...

And 20 at 12v overnight. So fast charge in the day and slow (er) charge at night.

[JoeC]

It looks like we have reached the end of life for some 2+ year old gels, so their replacment along with other factors make this look like a good time to collect some data and learn more about how the batteries are really being used each day.

Do I understand right that the 1420i is the way to go? is the larger one really that close to rElease, or will it be a while? Also, does the price look a lot higher? I have no power supply, and no car to charge from.

[Burgerman]

The larger one has replaced the smaller one and is available now. Its price is much the same as the smaller one was. Although that is being discounted if you can find one.

From a 12v supply both are the same power. You need a cheap (or good if you want) 24v power supply. This gives you the full 20 amp charge rate at 24v.

Its max output is 20 amps. Doesent matter if into 12v or 24v. (or 1,2v if you are charging 1 nicad!)... And its max wattage at higher outputs needs 24v.

So you can either use a car, (or a pair of very old gel batteries and a very cheap 12v power supply to use to charge them?) or a good bench power supply such as the one I got cheap on ebay.

But most people use one of these for use at home http://cgi.ebay.com/24V-20A-Power-Suppl ... 27b6d759a7

It is almost perfect and should only limit you by a couple of amps. And cheap. I have one and its reliable and solid.

Did I notice one of those 12v 100amp chargers on your bench? If so, I would be interested to know how long you can charge a 1500 Odyssey at these very high [ 100amp rates ] before the rate begins to fall.

[Burgerman]

Its a 40 amp power supply. Adjustable for amps and volts maximum. If I set it to 29.4v for odyssey AGM and 40 amps it does a perfect CC/CV charge. It stays at 40 amps solid for anything from a few mins to 15 mins or more depending on discharge level, cable length (big difference!) and gauge etc. But my van charges at 100 exactly. There it is only at 100 for 3 to 5 mins and then it starts to fall away as it charges.

Really?- how big a difference does the cable length make - I know from experience that poor soldering can make a huge difference - ie double or even triple the usual time.

Can you point me to some Hyperion graphs for the Odysseys at the Hyperion's max. amps?
