Dietz-Power wheelchairs

[Burgerman]

This shows the same thing.

The number of Ah you think you got depends on discharge rate, very very heavily and on the internal battery resistance and on the battery peukert level.

So small battery scooter = disaster!

There is NO tech info on those pdf files! Just some dumbed down marketing garbage.

Can you tell me EXACTLY what the charge algo is? CV voltage, termination based on current or time or hopefully both, and float voltage etc?

E.G. TECH CHARGE INFO:
For Gel, 14.10V CV at room temp, and terminates at 1/750thC or 12H CV limit whichever is first, then 13.45V float.
For AGM 14.50V CV terminating at 1000thC or 8 hors whatever occurs first, and 13.5 float.

Thanks!

I emailed them... Lets see what they say. I am frustrated by the fact that no charger manufacturer seems able to give any sensible info. And its impossible to know if a charger is any use without it.

I emailed them on Friday, no response as of yet. .

[Burgerman]

I now have the data...

See attached PDF.

They do two sets of charge algos...
One for gel, on which they carge CV at 28.8V (too high for gel) and stop charging (terminateCV) too soon by far at 1A, and then go to float at a correct 27.2V as long as you dont leave that connected for more than a couple of days. Too high for stotage float.
Every 2nd charge they do a strange overvolt thing for 1 hour. Thats a bad idea on gel too. So they are as bad as every typical mobility charger.

And they have a different algo (determined when purchased presumably) for AGM where they use 29.4V which again is too high for some but OK for Optima or pure lead batts. But again they stop charging too early, and they do that every other charge thing where they overvolt the battery. It wont do any good but wont hurt AGMs much. Better to charge for loger in the frst place.

So. Will it work? Yes. Anything works...
Is it ideal? Far from it esp on gel batteries. Will cost you around 30% lifespan. I wouldnt use this on gel.
AGM? It does what all mobility chargers do. It over volts, and cuts off CV at around 2 hours... Relying on float to top up the battery. It will. But it will take forever.

I have a rwd in at the minute should anyone want any specific measurements.

[Burgerman]

Caster centre to centre of the barrel might be interesting.

[rover220]

500mm barrel centres.

[Burgerman]

Thanks.
500 is 19.7 inches for the inflicted. Thats enough.

[hank]

What's measurements on your Salsa to compare John

[Burgerman]

F55 20.5
Salsa 19.0
Dietz 19.7

All to centre of castor pivot. Inches obviously... Because thats what my carer gave me! The dietz isnt as good as the olde F55 here, but better tahn the salsa. And that works great with 9 inch tyres and a bit tight with 10 but thats how mine is. So the Dietz should be the 3rd candidate that allows a centre plate and moving the seat back to get proper control/CG and stop it being an oil tanker.

[hank]

Thanks all good for centre footplates

[CPguy]

What is a "centre of barrel" in this context please? I only know the term barrel from wine and weapons.

[hank]

Between the front Centres of the shaft castor forks locknuts located in the frame

[CPguy]

Ok, so its measuring across, caster to caster. Thank you!

[steves1977uk]

Having seeing and a small test drive of the RWD Dietz chair, I must say I was very impressed with it!

Also rover220 was a super helpful guy. Looking forward to buying it and getting it set up properly.

Steve

[Burgerman]

Did it have a centre power footplate by any chance?


If I were to buy one, how would I get parts easily at a sensible price?
Say -20% and no VAT?

Anyone using VR2 or pre R-Net PG Drives controllers on ANY chair, can get OEM/Manufacturing (Covrers A, B and C access levels) on the Dietz download page here: https://dietz-power.com/downloads-dealer-login/

Anyone wanting the OEM version of the R-Net generic software, for all R-Net chairs, can get it on the Dietz download page too https://dietz-power.com/downloads-dealer-login/

Unlike all the rest that pretend it doesent exist, or refuse to supply, you can download it straight from their website. An enlightened manufacturer. And the only one I found ever...

[steves1977uk]

No it had the adjustable manual swing-aways footplates, which were needed for my foot control. A centre footplate wouldn't work for me since I need them separate and strong for to be able to push myself up with help.

Not sure about spare parts yet as I didn't get that far!

Steve

[rover220]

Glad you were impressed with it Steve, they are good kit. Steve's chair will need some very custom mods footrest wise but nothing that can't be achieved.

[Burgerman]

Does anyone know the caster width on the Q700R or/and Q500R still?

[rover220]

Does anyone know the caster width on the Q700R or/and Q500R still?

afraid not.

[Burgerman]

Bugger!

Someone must have one... I may have to call sunrise

[Arima]

I'll ask the dme for an engineering drawing for the q500r next time we speak.

[Burgerman]

The 700r is a better bet.

[Colin uk]

I've not come across the Dietz line before. Quite interesting.

I'm actually quite interested by this one at 53cm / 20.8" wide & the single rear wheel makes me wonder what that would be like to live with. The rear casters at the corners usually limits these in practice. Although this adds length, it also looks like you could back up quite close to a wall once that caster has spun.

It's not perfect, but the narrow frame, less rear swing restriction and avoiding the seat being to far forward from the rear drives is ticking some big boxes on initial look.

[rover220]

The slimline chairs are proving very popular, especially the 5 wheel model.

Hi All,

If you need any further details on the DIETZ range of powerchairs please let me know what you need and I will see if I have something I can get hold of for you.

hi i was looking for a showroom or dealers i could take my tina to see and try a dietz chair but found none in southeast england and its hard to commit to buying an unseen product so we have had to look elsewhere,did i miss a dealers here?cheers

Welcome aboard! Will be getting my new Dietz powerchair soon hopefully.

Steve

[Burgerman]

Any news yet? Looking forward to decent pics and opinions on it. Did you go rear drive?

[steves1977uk]

Yes BM, I went for RWD and have paid a deposit to rover. So should be getting it soon!

Well you've not paid it to me exactly.
